for example, let's say the new os depends on m5's exclusive thumbnail generator accelerator, and let's say it improves speed by a 20%.
now, your M1 notebook than on previous OSes uses standard gpu acceleration for thumbnails will not have this specialized hardware acceleration, it will have software fallback that will be 90% slower.
you won't notice it a first thought because it's stuff, fast, but it eats a bit of the processor.
multiply this by 1000 features and you have a slow machine.
I don't know how else to explain how an ipad pro cannot even scroll a menu without stuttering, it's insane how fast these things were on release
the Liquid Glass for example probably is not so great when it comes to resources. Probably works better with latest metal and hardware blocks on the GPU in M5 as opposed to using GPU cores and unified memory on 8gb M1 making latest macOS work not so great. I have the M1 8gb air and it is really slow on Tahoe. It was snappy just a couple of years ago on a fresh install.
Not upgrading any of my Macs ever again. I was a fanboy looking for every new update like a present, for 13 years, not anymore. It took one Tahoe burn all that trust. Never upgrading major OS versions on hardware from Apple again.
I've been holding out as you do for as long as I can but in 1-2 years the apps just stop working (some of them).
Win 11 is bad compared to Win 10 as well. I'm fairly new to Linux so I can't really form an opinion there.
I don't see why I need a new computer at the moment. In the past, I always got to a stage where the machine felt sluggish.
My next MBP will have 128GB memory, but these prices just wanna make me wait longer.
