I had a 2016 Intel MacBook Pro with integrated graphics. It was one of the first Apple laptops with a Retina display.
Well. That machine got progressively slower with each major release of macOS. The graphics performance degraded most clearly. If you did the gesture to show the desktop, the animation was noticeably janky - like maybe 20fps or so. Maybe Apple was increasingly using less efficient / more complex compositing or something with each new macOS version and the little Intel integrated graphics chip couldn’t keep up.
I almost forgot how bad it was - but then just before I sold it, I booted into recovery mode to wipe & reinstall the original OS. Turns out the recovery partition was still running whatever version of the OS that the machine shipped with - and holy cow performance was night and day. I’d almost thought I was making it up - but moving windows around was so delightfully snappy again!
I don’t think it was malicious at all on Apple’s side. I think they just didn’t care enough to make sure each new version of macOS didn’t degrade performance. I’m sure their engineers were excited to add visual flourishes using metal - even if older machines struggled to render them.
In retrospect I could have screen recording it or something for proof but I didn’t bother. I was getting rid of the machine anyway. Maybe I should have? But the difference was very real and very obvious.
(And no, I didn’t have any 3rd party software clogging up my machine. The only thing that would routinely peg my cpu was - for no reason - photoanalysisd and the spotlight indexer. Both part of macOS itself.)
