Well,
I'm still using Mojave, and intend to stick with that until it's no longer viable! Last year, I bought “new” hotrodded MPB, maxed out, because I didn’t want to mess with bad keyboards, problematic touch strips or what I believe to be a
HUGE step backwards in technology, all that crap you have to have hanging off the side of the new laptop (we used to call them “dongles”!) to connect to removable hard drives, headphones, external speakers or disk drives. And I have to admit to doing this mainly because I don’t want to be held ransome to Adobe Lightroom's subscription model, and their history of completely ignoring the desires of their users!
