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.

MacOS Catalina won't work on older Macs, but thanks to dosdude1's patcher, it can! Dosdude1 himself makes a cameo in this episode. Just updated my MP3.1. Regret updating from 10.5.5 (01) to 10.5.5 (02) using MacOS Catalina Patcher V1.4.4 and new MacOS Catalina Install download on a Late 2009 iMac does not work.

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).

Dosdude High Sierra Patch Tool

MacPostFactor (MCPF) 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.

Dosdude Patch Tool

I originally wrote this tool for a friend of mine who needed it. This very little tool patches x86 executables in order to let them have 4GB (instead of only 2) of virtual memory on x64 platforms. This tool comes very handy for applications which need a great amount of virtual memory like games, 3D renderization, multimedia etc. To gain these 2GB, you just have to use this tool to patch the executable (*.exe file) of the software you want to have these additional GBs of virtual memory. It can be used by clicking on it and choosing the file or through command line (e.g.: “4gb_patch file.exe”). It automatically creates a backup copy of the original executable.

Why things are this way on x64 is easy to explain. On x86 applications have 2GB of virtual memory out of 4GB (the other 2GB are reserved for the system). On x64 these two other GB can now be accessed by 32bit applications. In order to achieve this, a flag has to be set in the file’s internal format. This is, of course, very easy for insiders who do it every day with the CFF Explorer. This tool was written because not everybody is an insider, and most probably a lot of people don’t even know that this can be achieved. Even I wouldn’t have written this tool if someone didn’t explicitly ask me to.
