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.

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.
