Jun 17, 2020 Apple’s support document lists more than three dozen older media formats affected by the transition to 64-bit technology in macOS Catalina, like RealVideo, DivX, Sorenson 3 and FlashPix, in addition to other formats that were superseded by improved encoders. Examples of media that will be affected by the transition to 64-bit technology include video files from early Flip Video cameras that. The macOS Catalina Patcher is an application that lets you install and run macOS 10.15 on unsupported hardware. The program can download the latest version from Apple servers and create a bootable flash drive from it. To create media using macOS Catalina, you need to specify the location of the installer and select the media (at least 16 GB). You’ve now created a bootable macOS Catalina installer on your USB stick – next, you need to install it on your older Mac. Plug the USB stick into your older Mac. Restart your Mac while holding Option/Alt (depending on when it was made) to access Startup Manager.

In October last year, Apple releases a new version of macOS dubbed as ‘Catalina.’ This latest installment of macOS includes new features, including new apps for podcasts, music, and TV (replacing iTunes), the ability to use iPad as an external monitor, a revamped Photos app, and many more. Seeing this, it’s no wonder that some Mac users want to update their OS version to Catalina. However, not all of them have the luxury to do so.
Officially, macOS Catalina won’t work on older Mac devices that are deemed not powerful enough, according to Apple. Additionally, they provided the official list of the supported Macs:
This means that if you have a Macbook Air or iMac released in 2011, you won’t be able to upgrade your OS to Catalina. What version of macOS do you have?
If you’re unsure what version of macOS you have, you can check your macOS or OS X version by clicking the Apple icon at the top-left corner of Mac’s screen, then select About This Mac. In the Overview tab, look at the Mac model year below the OS version number. If the year is the same or above the previous compatibility list, then you should be able to install macOS Catalina formally. If not, read on.
Make your old Mac support macOS Catalina
Older Mac owners don’t have to worry. It’s not the end of the world. There’s a patch that lets you install Catalina to Macs that are not officially supported.
The patch is known as DosDude Catalina Patcher. DosDude Catalina Patcher is a third-party tool, meaning Apple does not develop the tool. It’s made by an individual developer instead. Keep in mind that just because you can make your old Mac run Catalina, it doesn’t necessarily mean it will always be a good thing to do.
Get Mac Os Catalina
Apple prevents older devices to run Catalina for a reason. As mentioned before, anything older than the officially supported hardware will most likely offer suboptimal performance using Catalina, not to mention that some features need newer hardware to function properly.
Despite that, it doesn’t mean that all old machines won’t run macOS Catalina well. Given that your hardware is capable enough, running Catalina shouldn’t introduce any lasting problems. The macOS Catalina Patcher is also updated regularly to address any issues that may surface. Otherwise, you can always downgrade your macOS to an older version if needed.
Install macOS Catalina on an older Mac
Before we begin, it might be a good idea to have a backup of your system using Time Machine, just in case. Creating a backup is always recommended. It’s not only useful for installing a new OS version can enable you to undo any changes after an update, which would be very helpful should something go wrong.
Once you are ready to jump into upgrading, follow the step-by-step guide below to install macOS Catalina on an older Mac using DosDude Catalina Patcher.
Now, you can enjoy the latest version of macOS on an older Mac. Remember that Apple doesn’t recommend you do this, so some troubles might show up when operating your device. Even though dosdude1, the developer of Catalina Patcher, introduces new patches regularly, it shouldn’t be surprising if the experience may not be as good as using Catalina on Macs that officially supports it.

While I have older hardware (a 2013 MacBook Pro) that I use for testing macOS betas—it's now running Catalina—it's often handy to have the latest macOS beta running in VMware Fusion on my iMac. With past OS releases, this has been a relatively easy process. With Catalina, however, attempting the install results in a black screen.
Thankfully, some enterprising Fusion users (Bogdam and intel008) have figured out a workaround. I tried it, and while it did work for me, I had to change the instructions just a bit (read on for the details).
Os Catalina For Older Macs 10
I'm not going to replicate the entire blog post here, as it's quite involved (and includes lots of helpful screenshots), but the short version is that it requires setting up a new VM (upgrading will not work!) as a macOS 10.14 guest, customizing the settings to change it to a Windows 10 x64 (yes, really) guest, launching the VM setup tool by dropping the Catalina installer app on it, interacting with the Windows 10 boot controller a couple times, then finally changing the VM back to a Mac guest OS.
That all sounds great, so I set to work, and all was progressing well…until I reached the part that reads…
Select “Boot normally” and press Enter.
This should then give you the normal boot progress screen: https://abkeen823.weebly.com/blog/free-audio-recording-software-for-mac-catalina.
But for me, it didn't provide the boot progress screen. https://abkeen823.weebly.com/blog/project-management-tools-for-macos. Instead, I saw a few boot failed messages—it looked like it couldn't find a boot volume—and I wound up back at the same screen.
After a few cycles of this, and not sure what to do about it, I tried something on a lark, and it worked: I shut down the VM, then opened its settings, went to General, and changed the OS type back to macOS 10.14 from Windows 10 x64.
When I then restarted the VM, macOS booted to the initial setup screen (select a region, etc.), and everything worked.
As it turns out, it seems that my installer had run all the way through before getting to the Windows controller boot screen for the first time, because what I did as a fix is listed as the next steps after the installer finishes, which the instructions describe as hapening after the first visit to the Windows controller boot screen. I have no idea why mine worked in a different manner.
One thing that may not be obvious from the instructions is how to actually get the macOS Catalina installer app you need to proceed. To do that, you need to install the Catalina profile from Apple's developer download page (login required). Then open System Preferences > Update, and let the installer download. When it's fully downloaded, quit System Preferences, and you'll find 'Install macOS 10.15 Beta.app' in your Applications folder.
If you don't want to install the profile on your actual Mac, you can follow the above steps in an existing virtual machine, then copy the installer to your actual Mac via drag-from-VM or via file sharing. You then drag this image into the new VM's setup screen to start the process.
Final note: I had to run the Install VMware Tools command twice. Run it once and then approve all the security requests and allow the extension, reboot, then run the Tools installer again, and it should work.
Great thanks to those who figured this out—having a virtualized beta to test with is incredibly convenient.
