I honestly do not understand what the 28GB Tahoe update contained. Like, I cannot imagine what all the code does. It'd take a lifetime to actually go through it all, and yet, here I am just using the same programs I did before it, just with rounder corners and some other pretty things. Actually wait, fewer programs, because some things break or have markedly less functionality.
The new liquid glass ui also fails a lot of basic accessibility checkpoints like contrast, readability, and increases cognitive load.
The rounded corners you speak of also hamper tap and touch targets for users with motor disabilities. The rounded corners make icons and other elements less distinct, increasing the possibility of touch or tap errors.
Used to do the same on Android plus more (you can disable most animations in developer)
Also highly recommend going in Accessibility on iOS and changing the screen swipe or slide effect or whatever. Results in much faster transitions. And all of this has always seemed to keep the phone cooler and battery life working longer.
If you want to get deeper disable all widgets completely (delete everything off the far left Home Screen). Disable weather auto updating based on location (if you deny it access to location then the Apple Weather app can just be set manually to track specific zip codes or cities).
I also do not get the insane folder thing everyone has on their Home Screen - I delete them all immediately along with all icons and keep one completely blank homescreen (with a cool background) and 4 things on the dock. Then only one other Home Screen with just a few additional icons in the corner. If you need any other app just search or go to the screen far right App Library !
It's not really "code" in the traditional sense
