Just my experience, and mainly using MX. I have two 2011 MBP 15 inch, each with bypassed dGPU. MX went on easiest on these. Effortlessly, in fact. Old A1181s also quite easy, 32 and 64 bit as needed. I fully expected this one to be a breeze, TBH, but I must also stress that I'm no expert. The single biggest thing was needing patience. Getting to a live desktop, even once the settings were ok, took forever. I had to steel myself to do something else until it presented me with a desktop!Interesting, thx. Why is it that it should be easier on mine?
