Here's a few examples - software requires signing and App Store accounts (literally called "Gatekeeper") which causes problems with OSS, you can no longer write kernel drivers on Arm64, many apps now require an avalanche of Vista-style "Do you want to allow this Thing Y/n" prompts, many other apps have to walk users through clicking into security settings to e.g. enable screensharing or productivity tools that use a11y hooks, the list goes on and on. Software on the Apple platform is becoming Less Useful over time and the list of things you can Do keeps getting smaller.
