macOS Catalina Patcher1.4.4

29 May 2020

Run macOS Catalina on your Unsupported Mac.

Overview

macOS Catalina Patcher lets you install macOS Catalina on Mac computers that are no longer officially supported. It can help you create a bootable USB drive that can be used to install macOS Catalina on Mac computers older than mid 2012.

Important disclaimer

MacUpdate team strongly suggests not to install macOS Catalina if you only have one computer or if it is your main machine. Also consider creating a Time Machine backup before proceeding with an installation and look through System Compatibility section. Do not attempt to install macOS Catalina on computers that are in the Not Supported list.

Important Info

APFS BootROM Support: If you have a machine that supports High Sierra natively, you MUST ensure you have the latest version of the system's BootROM installed. If you have NOT previously installed High Sierra, you can download and install this package to install the latest BootROM version. When installing, ensure your system is plugged in to power, or the update will not be installed.

  • MacBook3,1
  • MacBook4,1
2008 MacBook Air (MacBookAir 1,1)

Known Issues

  • AMD/ATI Radeon HD 5xxx and 6xxx series graphics acceleration: Currently, it is not possible to achieve full graphics acceleration under Catalina on any machines that use a Radeon HD 5xxx or 6xxx series GPU. If you have a machine with one of these GPUs installed, I'd advise upgrading it if possible (can be done in 2010/2011 iMacs, iMac11,x-12,x), disabling the dedicated GPU if using a 2011 15" or 17" MacBook Pro (MacBookPro8,2/8,3, instructions to do so can be found here), or not installing Catalina. Running Catalina without full graphics acceleration will result in extremely poor system performance.
  • 2008 Mac Pro 3,1 AMD GPU Support: FIXED as of Catalina Patcher 1.2.0.

It worked on my mid 2011 mac, but it has virtually crippled the functioning of the graphics card, and slowed it to a crawl. Anyone know how to reverse the process? I don't really want to buy a new machine.

My iMac 27" mid 2011 will be "almost unusable" due its AMD Radeon 6770M GPU so that simplified the choice for me. Seems that category does take in most of the potential audience for this patch. I do commend the author's initiative for making this available for the Mac users who can take advantage of the patch. I do NOT commend Apple for putting its much abused customers in the situation where they desperately look to such solutions. It's not like the customers demanded the hugely expensive crap GPU's, Fusion Drives and lack of vital ports that make sticking with Apple as much of a curse as a blessing. It is as though Apple, when it isn't treating its customers with utter contempt, is testing them for just how much they are willing to take before quitting. I haven't bought a Mac from Apple in almost 10 years and whilst I am periodically tempted, Apple does more than enough to convince me that it doesn't want to sell me another Mac.

I do not see any reason for not granting the author five stars. Catalina is now running on my mid 2011 mini.

Mostly works. However Brave browser no longer loads, and Zoom doesn't play back the video from my iSight on my 2009 iMac. It is unclear if that is due to the install, or baseline incompatibility between Catalina and my hardware.

It looks like this package is very well maintained. I have also been impressed with how seamless all the patches that make the older hardware work with Catalina have been integrated. This developer obviously has very deep insight into how macOS Catalina works down to details.

Hmmm. Does anyone know if this will work with my mid 2007 MacPro....the one you couldn't run Maverics and higher on? It would be so helpfull. Or is there a version that is not Catalina, say Sierra even. Thanks.

The security concerns I have with the depth of what's possible with software like this kind of scares me. The fact that it's free also plays into that somewhat...

I have used macOS Mohave patcher for several months and have nothing but good to say for the developer (dosdude1) who saved my 2008 Mac Pro from obsolescence. I run intensive Audio Production software and it all works without a hitch. (The only thing I can't do is the AppStore because of my choice in harddisk formatting). As far as I'm concerned the developer is doing the Apple community a massive service and gets a ton of gratitude from me. I am writing this because the Catalina Patcher has replaced the Mohave Patcher on MacUpdate and for hardware reasons I will not be updating to Catalina, but I wanted to reassure anyone who is feeling uncertain about whether it is worth it, for me, dosdude1's patch has been a lifesaver (as anyone who has glanced at the new Mac Pro price tag can understand.) Don't be afraid of saving your Mac from Apple's unnecessary obsolescence. I couldn't be happier.
