How to Install Oracle on a Mac (2020)

In this post, you’re going to learn the exact steps to take to install Oracle on your Mac computer.

This guide includes:

  • step-by-step instructions on downloading and setting up the required software
  • screenshots at each stage
  • explanations of the configurations you need to set (such as connecting to the database)

So if you want to set up Oracle on your Mac computer, you’ll love this guide.

Let’s get right into it.

Overall Process

Installing an Oracle database on a Mac computer is a bit different from installing it on a Windows or Linux computer.

Oracle doesn’t support running an Oracle database directly on a Mac computer. You can’t install Oracle Express, for example, in the same way that you can on a Windows computer.

The good news is that you can use a Virtual Machine. To get set up with Oracle on your Mac, the general process is shown below.

Note: An alternative to using a Virtual Machine is using Docker. I believe using Docker is a simpler process and seems to less resource-intensive than a Virtual Machine. I’ve documented the entire process here if you want to try that method instead: How to Set Up a Database on Docker.

Let’s take a look at the requirements, and then get into the steps.

 

Requirements for Oracle VM on a Mac

So, what do you need to be able to run Oracle using a VM on a Mac?

The requirements for running a virtual machine are listed on Oracle’s page here (last updated 20 Jun 2019), and are shown below:

  • At least 2GB RAM. Default VM is 1G RAM, for better performance increase.
  • At least 15GB of free space
  • 2GHz processor (a lesser processor will be acceptable but slower)
  • Mozilla Firefox 2.0 or higher, Internet Explorer 7 or higher, Safari 3.0 and higher or Google Chrome 1.0 or higher
  • Admin privileges on your computer

My current Mac is a 2018 MacBook Pro with 8GB of RAM and a 256GB hard drive, which runs the VM pretty well.

On my previous MacBook Air (2015, 4GB RAM), it actually ran pretty slowly, because the 4GB RAM is split with 2GB for the VM and 2 GB for the Mac OS, bringing both systems to a crawl. MacBook Airs are not designed to be able to run intensive programs such as VMs.

If you really want to use Oracle on a Mac, but don’t quite meet the requirements, you can use Oracle Live SQL, which is a web-based Oracle database.

Assuming you want to install Oracle on your Mac, let’s look at the steps.

Step 1: Get VirtualBox

The first step to getting Oracle on your Mac is to download a program called VirtualBox. This program allows you to run virtual machines, which are self-contained operating systems. It will let you run a Windows or Linux operating system inside your Mac.

I suggest VirtualBox because it’s free, and Oracle provides a ready-made file that you can use with it. One alternative is Parallels, which I explain at the end of this guide.

To download VirtualBox:

Step 1A: Go to the VirtualBox website: https://www.virtualbox.org/wiki/Downloads (opens in new tab).

The current version is shown at the top of the page (currently it is 6.2.6).

VirtualBox download page Step 1B: Click on “OS X Hosts”. This is a direct link to a .dmg file, which is the installer file for Mac.

The file will start downloading. It’s approximately 122 MB.

VirtualBox Download

Step 1C: Once the file is downloaded, open it.

Open VirtualBox

Step 1D: Double click the VirtualBox.pkg icon in the window that appears.

VirtualBox download open

Step 1E: Click Continue if a message appears about installing the package.

VirtualBox package confirmation

Step 1F: Click Continue on the welcome screen.

VirtualBox Install

The installer will tell you how much space VirtualBox will take up (approx 251.8 MB).

Step 1G: Click Install.

VirtualBox Install

Step 1H: Enter your password if prompted.

Enter Password

The program will now be installed.

VirtualBox Install

Step 1I: Once completed, it will inform you the installation was successful.

VirtualBox installation done

Step 1J: Click Close, and move the installer to the trash.

Installation Failed?

Did you get an error saying the installation had failed for VirtualBox VM?

VirtualBox Install Failed

The installation failed.

The Installer encountered an error that caused the installation to fail. Contact the software manufacturer for assistance.

I got this error when attempting to install VirtualBox on 10 May 2020, running macOS Catalina 10.15.4.

How can you resolve this?

These are the steps I followed (thanks to Daniel Meechan’s article here):

Follow the steps from 1D to 1G above, stopping when you get to the screen with the “Change Install Location” and “Install” buttons. Don’t click Install.

Open System Preferences from the Apple menu.

MacOS System Preferences

Click on Security & Privacy (second row, far right).

Click on the General tab.

MacOS Security & Privacy

You should see a greyed-out message at the bottom of the window saying “System software from developer “Oracle America Inc.” was blocked from loading.

Security Password

Click the padlock icon on the bottom left of the window to unlock this window.

Enter your password and click OK.

Security Unlocked

The disabled text and buttons should now be enabled.

Click Allow.

Enter your password again.

Now, return to the VirtualBox installer and click Install.

Resume the steps above from 1H. The installation should now be successful.

 

Step 2: Download the Oracle Developer VM

Now you’ve got VirtualBox installed, you need to download the file that contains the Oracle database. This is the virtual machine file and is provided by Oracle.

It’s called the “Oracle Developer VM” or “Oracle Developer Day VM”, as it was originally created for developers but it has expanded since then.

To download this file:

Step 2A: Visit the Oracle Developer Day download page here (last updated 20 June 2019).

OTN Download Page

This page lists the versions of software it comes with. At the time of writing, this is Oracle Linux 7 with Oracle Database 19.3.

Step 2B: Scroll to the bottom of the page and click the Oracle DB Develop VM link.

OTN VM Download

Step 2C: On the popup that appears, check the box to accept the license agreement, and click the green Download button.

Accept Agreement

 

Step 2D. You’ll be asked to log in to your Oracle account. If you have an account, enter your details. If you don’t have an account, you can create one. It’s easy and free.

Oracle Login

Step 2E: Once you have logged in, the Developer Days VM file will start downloading. It has an “ova” extension.

Developer VM download

This file is about 7GB so may take a while. I’ve had no issues downloading it with Chrome, but you may want to use a download manager if your connection isn’t very good.

 

Step 3: Set Up the Oracle VM

Now you have downloaded the Oracle VM file, it’s time to set it up.

Step 3A: Open VirtualBox. I usually do this by pressing Command + Space and typing in VirtualBox.

VirtualBox CMD Space

VirtualBox Main Screen

Step 3B: Click File, then click Import Appliance (or click the Import button at the top of the main screen). The Appliance to Import screen is displayed.

Import VirtualBox

Step 3C: Click the Choose File button on the right of the textbox, which is the little yellow folder icon with the green arrow. (Leave the Source textbox as the default “Local File System”).

Step 3D: Select the DeveloperDays OVA file you have just downloaded, and click Open.

There’s no need to extract the file before opening it.

VirtualBox OVA open file

Step 3E: Click the Continue button on the main installer.

Import VirtualBox

Step 3F: Click Import on the Application Settings page.

VirtualBox Appliance Settings

Step 3G: Click Agree on the popup that appears.

VirtualBox Agree

Step 3H: The import process will begin. This process took about 2 minutes for me.

Importing

Step 3I: Once the installer is finished, you should see “Oracle Developer Days (Powered Off)” on the left panel of the VirtualBox window.

This means the VM is installed but not running.

VirtualBox Installed

 

Step 4: Run the Oracle VM

Now the installation has finished, it’s time to run the Oracle VM.

Step 4A: To run the Virtual Machine, click once to select “Oracle DB Developer VM” and click the green Start arrow.

VirtualBox Installed

There will be a minute or so of a black screen with white text as the virtual machine loads, and a black screen.

Virtual machine loading

A Linux desktop will appear, and a moment later a terminal window will appear:

VirtualBox VM terminal

The virtual machine is now ready to use.

 

A Note About Firewall and Port Forwarding

In previous versions of VirtualBox and this VM, we had to take extra steps to make the VM visible to the host (the Mac that you are running the VM on). We also had to set up port forwarding, which would allow us to enter in an IP address such as “localhost” on the Mac and have it forward to the Virtual Machine.

However, this configuration is already done in the latest version. So, these steps are no longer needed. Once the VM is running, as mentioned above, we can connect to it using SQL Developer (or another IDE).

I’ve removed these steps from the guide, but the comments below still refer to them.

Let’s continue!

 

Step 5: Test Using SQL Developer

The last step is to test this connection using SQL Developer.

Step 5A: Open SQL Developer on your mac. If you haven’t downloaded it, you can download it from the Oracle website.

Step 5B: Create a new connection by clicking on the green + icon.

SQL Developer new connection

Step 5C: Enter these details for your connection:

  • Name: whatever you like. A name such as “VirtualBox Oracle” is OK if you can’t think of anything.
  • Username: hr
  • Password: oracle
  • Check Save Password if you don’t want to enter the password every time.
  • Hostname: localhost
  • Port: 1521
  • Select “Service Name” instead of “SID”
  • Service Name: orcl
  • Connection Type: Basic

Your connection screen should look something like this:

New Connection

Step 5D: Click “Test” to test the connection. The message should say “Success”, which means the connection has worked.

Success

  • If it says “Listener refused the connection with the following error: 12514”, then you likely have the Service Name incorrect.
  • If it says “Listener refused the connection with the following error: 12505”, then you likely have selected SID instead of Service Name.
  • If it says “Test failed: ORA0-1017: invalid username/password, logon denied”, then you likely have an incorrect username or password, or one of several other issues.

I’ve written more about resolving Oracle connection issues here.

Step 5E: Click Save to save your connection in the list.

Step 5F: Click Connect. After a moment, a new SQL worksheet window is opened on this new connection.

New Tab

You can now run SQL queries on Oracle on your Mac. This will work for as long as you have the Virtual Machine running in the background.

To test this, you can run this query:

SELECT * FROM v$version;

This will show the current version of the Oracle database.:

Oracle Version

Your Mac can now access your Oracle database running on your own virtual machine!

 

Shutting Down

Once you have finished with your Oracle SQL session, you can shut down your VM. To do this, go to Machine > ACPI Shutdown. The Virtual Machine will go back to a “Powered Off” when it’s done.

VirtualBox Installed

 

Alternative to VirtualBox: Use Parallels

One alternative to this process of using VirtualBox and the Oracle VM is to use Parallels. Parallels is a VM application, just like VirtualBox. The key differences are:

  • It has a different VM file format, so you can’t use Oracle’s VM files.
  • It’s a paid tool, unlike VirtualBox which is free.
  • You can install your own operating system on it, so you can run Windows 10 for example, instead of Oracle Linux. VirtualBox allows this as well.
  • You can install your own version of Oracle on there, such as Oracle Express or an earlier/later version of Oracle.

The steps are quite similar to setting up VirtualBox. To set up Parallels for an Oracle database on your Mac, the high-level steps are:

  1. Purchase and download Parallels for Mac (or use the free trial).
  2. Install Parallels.
  3. Set up a new Virtual Machine on Windows 10. I don’t know if you have to download the Windows 10 (or other Windows version) ISO file, or if Parallels can do that for you.
  4. Once the operating system is installed, download Oracle or Oracle Express from the Oracle website, inside your virtual machine.
  5. Install it on your virtual machine as though you’re running it on a Windows computer.
  6. Configure the port settings in a similar way as you did for VirtualBox
  7. Connect to the virtual machine from SQL Developer on your Mac.

I’ve used Parallels in the past for this. The only reason I stopped was because my MacBook air didn’t have the specs to keep up with running a VM.

Summary

Some developers want to run an Oracle database on a Mac. While Oracle is not natively available on a Mac computer, it’s possible to run Oracle or Oracle Express on a Mac using a virtual machine.

This article describes the steps you need to take to set up the existing Oracle Developer VM and VirtualBox on your Mac to get it up and running.

    Status: Failure-Test failed: Listener refused the connection with the following error: ORA 12514, TNS listener does not currently know the service request

    1. Hi Dipika, I would suggest checking your connection parameters, especially the IP address of the virtual machine.
      I’ve got an article here on this error but it may not solve the issue for connecting using a Mac.

      1. Hi,

        I tried following the installation process on my New MacBook Air with M1 chipset. However , I got the following error while accessing oracle DB developer through VM manager :

        Kernel driver not installed (rc = -1908) and it’s failing to open a session for virtual
        Machine Oracle DB developer VM.

        Kindly help

    2. Hello Dipika, i encountered this error as well. I am running 19c. When you start your oracle database on the virtual machine, it gives you some database information. Please check to see what those credentials are, they may be different from what was used above. Check specifically for these:

      Oracle SID: sid_here (Connect using SID instead of service name as described above)

      Pluggable DB: check for the ‘username/password@ORDS’ credentials given in this section. you’ll notice a place like (‘if sqlplus username/oracle@ORDS’ connects ORDS pdb has already been installed)

  3. Hi,

    While I am trying to import the OVA file on mac os, I get the below error

    Failed to import appliance …/Downloads/DeveloperDaysVM2018-10-16_09.ova.

    Result Code: NS_ERROR_INVALID_ARG (0x80070057). Any thing I can do to resolve it?

    Thanks

  4. Hi
    Thanks for your write up.
    I’m on a Mac on Mojave 10.14, I can get the Oracle DB Developer VM running but I can’t past step 5.
    I have no admin setting to reach the firewall settings, port etc?
    Thanks

    1. Hi Matt,
      Good question. I’m not sure why the Admin section would not be appearing. I remember having this issue a while ago but I don’t remember how I resolved it.
      I admin setting up a VM for this is a bit tricky so I would suggest Googling why the Admin menu does not appear.
      Sorry I couldn’t be more helpful!
      Ben

      1. On an enterprise (corporate) system, the MacOS might be locked down from the user and is denied permission to get to the admin section. Unfortunately, this is pretty common. It would help if you mentioned that it was the admin section of MacOS. It’s confusing to direct us to the VM and then switch gears to the MacOS without any indication that you’re doing this. Otherwise, great and helpful article.

    2. Did you resolve this? I am stuck too. He said system menu, admin then firewall but none of those options are there. I don’t see the system menu. I click settings but there was no admin tab. Any help?

  5. Hi Ben,

    Thanks so much for this article. It is great help.

    It appears Oracle has come out with a new release of VirtualBox (6.0) since you wrote this article which I have installed. The interface is slightly different than you describe. I am working on the step to set up the firewall rule. In the upper right hand corner of the 6.0 interface is a icon (which I might label a 3 server network icon). When clicking on it a drop down displays, with a variety of options including a wrench/tools icon. When I click on that, I get to a screen with a Wifi option. It displays a message, No Wi-Fi Adapter Found. I am able to open up Firefox and surf around on the VM so must have WiFi connectivity, but still have that message.

    In the upper left hand corner of the VM, is a menu labeled Applications. Underneath it, is a submenu named Sundry which has an option for Firewall. When I open it up I get a message: Trying to connect to firewalld, waiting…

    A quick Google search about the No Wi-Fi Adapter Found returned some entries from 2013 about installing an extension to VirtualBox. Before I go down that path, I thought I would ask you if that is what you recommend or maybe I missed something.

    Also, I noticed on my virtual machine the command ipconfig is not installed. On my MacBook, it is in /usr/sbin, but nowhere to be found on the VM. Any thoughts on that?

    Thanks again. This has been a great start for me.

    1. Hi John,
      Glad you like the article.
      Thanks for the question. Yeah it looks like a recent version has come out since writing this. I’ve only set up this VM once or twice so I’m not that familiar with all of the issues or intricacies of it.
      It’s strange that the icon is different and the firewall setup is not working.
      I would suggest asking a question on AskTOM – that’s a support forum for Oracle issues. They may be able to advise what the issue is or at least advise what else you can try.
      Sorry I couldn’t be more helpful!
      Thanks,
      Ben

  6. Hello,

    Your steps have worked just fine for me thus far (up to Step 5, haven’t tried this yet). This is by far the simplest tutorial on running Oracle on Mac that I’ve found.

    I notice SQL Developer runs a little slower in the VM (Oracle Live SQL is worse). I suspect Step 5 may make things better but my question is in regards to the safety of it. This is a little new to me so I have some questions. Does opening ports expose my Mac to security issues, is this port only open when VirtualBox is running? Is there a way to make this more secure for peace of mind? I guess I’m just concerned with how safe making the VM visible to my Mac would be.

    Thanks so much for your detailed tutorial.

    1. Also, when logging into SQL Developer and it says there’s an updated version, if I click on that link it will open the VM Firefox browser and take me to the download page from the Oracle site. Can we actually update our version of SQL Developer this way or is that not possible since it’s still technically running on my Mac.?

      1. Hi,
        Are you opening SQL Developer inside your VM or on the Mac?
        I think you can update it either way – the version on the VM or the version on the Mac.
        I don’t use the version inside the VM, but if I did, I think it would update OK.
        If you’re not sure, you can manually download it from the Oracle website and install it.

    2. Hi George,
      Thanks, glad you like the article!
      I’m not sure about the security issue behind it. Networks and ports is not a strong point for me. I would suggest asking the AskTOM forums, they can probably advise on the impacts I think.
      What are the specifications of your Mac? I ran a VM on a 2015 MacBook Air and it ran quite slowly, but on a 2018 MacBook Pro it’s running very well.
      Thanks,
      Ben

  7. Nice article! Helped me a lot. Needs to be updated to the current version of the VM and some extra screenshots would be nice. I also found that the auth should be system/oracle and service name=orcl. Also, the port forwarding was already set up in the VM, so no need to actually do this step, but nice to have it document in case it gets deleted. Also don’t need the IP for it, just leave it blank. Thanks for posting! I’m happily connected to my VM with Sql Developer on my Mac. Good times!

    1. You filled in/clarified the missing info. Thanks! Great article Ben. Just needs a couple of updates to align with latest version of VM. As mentioned by Digitalman42, it’s actually a bit easier now with some of the configuration already installed.

  8. Hi, At step 5 when I’m trying to open firewall configurations it is giving me an error stating – “Failed to connect to firewalld. Please make sure that the service has started correctly and try again.”

    Thank you so much for the tutorial and I’d appreciate any HELP on resolving the ERROR I got.

    Tj

    1. Hi Tj,
      I’ll take a look at the error, however it’s not something I’ve seen before. It might be easier for you to Google it (if you haven’t done so already) as others may have experienced it.
      Ben

  9. thanks so much for this tutorial, it worked like a charm. I have the same issue with configuring the firewall and opening ports, as mine shows as having a wired connection, but it’s fast enough using SQL dev within the VM, so I’m ok with that. Anyway, just wanted to say I really appreciate you taking the time to do this!

    This post was very helpful and the steps were easy to follow and install each component. My environment works correctly; however, when I try to install sample schemas from the Oracle site, I am having problem with the users being setup. I don’t seem to have access to create these schemas. Probably user error, but trying to figure out how to get these sample schemas created.

    https://docs.oracle.com/en/database/oracle/oracle-database/18/comsc/installing-sample-schemas.html#GUID-B0BEE222-D8B0-4B68-B359-DEA153956EF6

    administrator to grant you the necessary privileges

    what should i do?

  15. Thanks for this guide. I was able to perform all the steps and the test using SQL developer worked. My confusion is related to my classwork for a course I’m taking on database systems using Oracle.

    I’m completely new at this, so my questions or confusion may not even make sense, sorry in advance, but hopefully I can get some guidance.

    My class instructs me to download 11g Express Edition from Oracle (which I obviously can’t run on my mac, which is why I am here). This guide seems to indicate I can do what I need using this method, and my instuctor said that students had used a VM with some success in the past. Part of my confusion is understanding the difference (and how they relate) between 11g Express and SQL Developer. I think that 11g is the database, and SQL is a way to access and interact with it?

    What is throwing me off is your example to test using SQL and using the hr username and oracle password, is this simply a sample database? How do I set up my own database on my Mac to do my coursework?

    This is where the dots aren’t connecting for me. I can’t tell if what I am trying to do is even possible, or if I am just missing something. My only other option to use an old PC I have access to, but this is less than ideal. I would prefer to run everything out of my Mac if possible.

    Thanks in advance.

    1. Hi Brandon, thanks for the questions.
      Oracle Express is the database itself, which is the software and files that store all of the tables and data and everything that makes the database work. Oracle Express is a smaller but easier to set up version of Oracle’s full database, and it’s great for getting started. Oracle Express 11g was the most recent version of Oracle Express up until a year or so ago, and now I think the latest version is Oracle Express 19c.
      Oracle SQL Developer is an application that lets you access and interact with the database, as you mentioned. You’ll need Oracle Express to work with the database, but you can use another application instead of SQL Developer if you like. SQL Developer is quite easy to use, and free, and is often recommended by those working with Oracle (myself included).
      The difference with my article and what you’re referring to is that my article uses a VM that’s provided by Oracle. Their VM includes the full Oracle Database (not Oracle Express), and this database includes a sample database called “hr”. I suggest testing with this because if you’re able to connect to this “hr” database that’s inside the VM, then the setup process has worked.
      The good thing is that once this has been done, you can then set up your own database and tables and use that instead of the “hr” database.
      So, in short, if you can complete everything in this article and get the VM working on your Mac, you should then be able to create the database you need.
      Hope that helps. Let me know if you have any other questions.

      1. Hello Ben,

        Your article is amazing and it worked perfectly for me too.

        However, I am struggling with creating my own database, please can you share a guide on how to do this properly after VM is working without using the “hr” database

  16. Hi,
    I installed this and it’s ok but I need from Northwind database because my SQL course works with this database. Please, can you help me with this!

    1. Hi Tanya, I don’t think Oracle has released a Northwind database as it’s an SQL Server data set. But if you have the SQL scripts to create it from SQL Server you can convert it to Oracle by changing some of the data types and syntax I think.

  17. Hi, I’ve installed the VM on my MAC and when I tried to run the Oracle DB Developer, I have a faillure :
    Kernel driver not installed (rc=-1908)

    Make sure the kernel module has been loaded successfully.

    where: suplibOsInit what: 3 VERR_VM_DRIVER_NOT_INSTALLED (-1908) – The support driver is not installed. On linux, open returned ENOENT.

    Can you help me please ?

  18. I just want to say thank you so so so much!! the article is so insanely helpful, everything worked for me perfectly, I appreciate your help!

  19. “You must specify a machine to start, using the command line.

    Excellent blog, I followed steps and am able to install oracle and connected successfully from mac.
    Thanks for such wonderful detailed and needed guid!

  21. I am stuck at step ” Step 3D: Select the DeveloperDays OVA file you have just downloaded, and click Open. ” when I try opening it, it’s all grey meaning that they are not compatible maybe? I don’t know what the problwm is do i need an application to open it?

    1. Hi, I think the OVA file is opened by VirtualBox. I think you can open VirtualBox and follow the Import process to import this OVA file to start the virtual machine.
