Just wanted to share that I was successful on installing Mojave 10.14.2 on a Precision T1650.
This system was shipped with an Intel i3-3220, I was not able to get the iGPU (HD2500) working correctly after installing macOS.
I just got a flickering screen with a mouse cursor shown, the only way to get some screen output was booting with "-x".
Therefore I decided to put my old Geforce GTX650Ti into the system to get at least some metal support.
Now the. system is working perfectly.
For everyone else, I attached my CLOVER folder. Feel free to use it for your own build.
