@Roger Worrod. I am running macOS sierra 10.12.4 on a MBP late 2008 with a little help (no, a lot of help) from dosdude1. the laptop runs fine, but I installed parallels desktop lite (PDL) to run W10, because I had used the trial version of parallel desktop to run W10, with no problem. PDL refused to start because my hardware did not meet with its specifications. Apparently, it checks the hardware type and year (mine is MBP4,1; 2008) and decides whether to run or not. 2b1af7f3a8
