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.

The video below demonstrates a tutorial walking through the process of using the DosDude Catalina patcher tool to install the macOS 10.15 system software on an unsupported Mac. If you’re going to attempt to install MacOS Catalina on an unsupported Mac, do so at your own risk, and let us know how it goes in the comments below. 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.

Can you give me any directions ?

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.
