Question :
I read somewhere that it is possible to install the latest version of OSX 10.10 Yosemite on my Mac, even though the official installer refuses to install.
Can you give me any directions ?
El Capitan On Unsupported Mac
Patched Sur is a UI patcher for macOS Big Sur, designed to make it easy to run macOS 11 on unsupported Macs. This patcher hopes to allow any user of any knowledge to patch their Mac, while still giving you freedom on how you want to use your Mac.
Answer :
Installing newer versions of OSX on slightly older Macs that do not meet the official system requirements can be done using MacPostFactor (MCPF).
MacPostFactor also supports installing OSX versions up to OSX 10.10 Yosemite on older Macs. And a new version that supports installing OSX 10.11 El_Capitan is in the works.
For more info (and downloads), go to the info page on MacRumors.com :
or see the (less readable) official page of the MacPostFactor team :
- El Capitan On Unsupported Mac; Mac Os El Capitan Patcher Tool For Unsupported Macs Windows 10; Mac Os Yosemite Patcher; Dosdude1 Yosemite; If you prefer to select Mac OS Extended (Journaled), you won't get any system updates. APFS will work on the End 2009 models and later as with High Sierra.
- OS X Yosemite on Unsupported Macs. MacOS Extractor, OS X Patcher, and MacPostFactor are apps that guide you through patching and installing OS X El Capitan (10.11), Yosemite (10.10), Mavericks(10.9), or Mountain Lion (10.8) on your older Mac.
- Good news everyone - the RMC Team has a OS X Patcher I tried today that is a piece of cake. After booting a test installation off an external firewire drive, I was successful upgrading my 10.7.5 install (MacBook 2,1) using the installer created by this script. I like that it is a project you.
…in short :
!!! THIS IS FOR (RATHER) EXPERIENCED MAC-USERS ONLY, AND SHOULD NOT BE DONE ON YOUR ‘ONE AND ONLY’ MAC !!!
