How to install Catalina on older Mac, update macOS on an old MacBook

The Mac updates its work system for laptops and macOS computers (formerly Mac OS X), corresponding to the clock, annually with new options and improvements. This is all high quality, however, the newest MacOS model, known as Catalina, will not work on a Mac older than 2012 and, in the case of the Mac Pro, in late 2013. Which may imply that your Macs have not been updated, except that you watch this tutorial.

Before proceeding and following the recommendation at, a warning. There is a purpose for which Apple chooses not to help the new Mac work system on older Macs. Older Macs simply do not have the required mandatory elements or power to meet the demands of more modern programs. So, if you’re putting Catalina or a newer model of macOS on an old Mac, be it Mojave, High Sierra, Sierra or whatever, don’t expect it to work easily.

Is my Mac too old to update?

Do you need to update your Mac with the latest macOS model? Officially, it may be too old to run the updated software program.

Apple recommends that macOS Catalina runs on the next Macs:

  • In early 2015 or later, MacGuide fashion
  • MacGuide Air fashions from mid-2012 or later
  • MacGuide Pro fashions from mid-2012 or later
  • Mac mini fashions from late 2012 or later
  • IMac fashions from late 2012 or later
  • iMac Pro (all fashions)
  • Mac Pro fashions from late 2013

Apple recommends that macOS Mojave runs on the next Macs:

  • Mac Fashions from 2012 or later
  • iMac Pro (from 2017)
  • MacGuide fashions from 2015 or later
  • MacGuide Pro fashions from 2012 or later
  • MacGuide Air fashions from 2012 or later
  • Mac mini fashions from 2012 or later
  • Late 2013 Mac Pro fashions (plus mid-2010 and mid-2012 fashions with Metal-compatible GPU)

This implies that if your Mac is older than 2012, it will not be able to formally use Catalina or Mojave. In the case of Catalina, which incorporates all the old fashions of the Mac Pro, the pre-trash bin.

MacOS High Sierra had few options. Apple mentioned that it will happily work on a MacGuide or iMac in late 2009 or later, or on MacGuide Air 2010 or later, MacGuide Pro, Mac mini or Mac Pro.

We have a macOS compatibility check here, so you can see what variations of macOS your Mac should offer the chance to run.

However, it is possible to run more recent variations of macOS on older Macs, thanks to an update made by a developer. Although you can anticipate problems. This hack would not work with every Mac, however, many are aligned. You can see if your Mac is supported here.

Using Catalina on an unsupported Mac can be considered a violation of Apple’s phrases. For data on Apple phrases, read: you must agree with Apple phrases

Using Catalina on an older Mac

The downside is that if you have an older Mac, you simply cannot install the enhancement file on the Mac App Store. But not all parts are out of place. You can download a macOS Catalina Patcher from a developer known as DOSDude1. The patch allows you to install Catalina on an older Mac.

DODDude1 provides a video tutorial on its website here. We’ve simplified the steps below, however, we suggest that you simply watch his tutorial.

  1. Download the newest model of the Catalina patch here. (You can make a donation).
  2. Open the Catalina Patcher application.
  3. Click Continue.
  4. Choose Download a replica.
  5. The download (from Catalina) will start – since it is almost 8 GB, it will probably take some time.
  6. Connect a flash drive.
  7. Choose “Create a bootable installer” from the options.
  8. Connect the bootable installer to the Mac that you need to update.
  9. Restart your Mac while holding down the Option / Alt key. This will open your Mac in Startup Manager.
  10. Choose the bootable configuration unit and Enter.
  11. Your Mac should now open in Recovery.
  12. Choose Reinstall macOS and wait for the new macOS model to be installed.
  13. After the installation is complete, you want to restart your Mac in restore mode and select the drive that makes up the bootable installer.
  14. Now select macOS Post Install and the necessary patches can be installed on your Mac for Catalina to work.
  15. Choose Force cache rebuild when patches are used.
  16. Restarting.
  17. When you restart, your Mac should now boot to a fully functional copy of macOS Catalina.

If you are using a macOS model older than High Sierra or Mojave, you may want to format your laborious unit for APFS.

How to use Mojave on an old Mac

As in Catalina, a correction device was written DOSDude1 that allows you to install macOS Mojave on an old Mac.

You can download the Mojave Patch Tool here.

How to use High Sierra and older on an older Mac

DOSDude1 wrote an identical patch for High Sierra and the previous Sierra. With the patch installed, it is possible to return to the fashion of early 2008. It is unlikely to become a dream, which is why Apple does not suggest this action plan. But you need to be ready for tolerable efficiency.

Why you shouldn’t install MacOS Catalina on an old Mac

We do not suggest technology novices to make this resolution: it requires an average degree of technical experience.

Remember, we are in favor of Apple’s official recommendation on this, which implies that if something is not adequate – and that is always an option with a configured operating system, even if you are using official software – your warranty in all likelihood it will not prevent. Obviously, your Mac is unlikely to be in line with any warranty prior to 2008, which may not be an excessive amount of priority.

Back up your Mac sooner than persevere. And remember 2 more caveats.

At some level, Apple can fix this hack and prevent it from working sooner or later. So, if you are excited and completely satisfied with the fact that dangers and difficulties cost you a price, jump in while you still can.

Otherwise, you may have thought about trying to read how to promote an old Mac.
