Stop egregiously upcharging on RAM and storage.
Allow full sideloading. Hide it away in deep place with warnings so normal people don’t use it, but let us nerds have it.
Stop charging $100 for developer accounts.
Release your dev tools so people can build apps for iOS using computers that aren’t Macs. Also, full XCode on iOS itself so you can make iOS apps on iOS.
A Mac Pro with an M4 Ultra AND NVidia GPUs. All other consumer computers will bow down.
Get the Rosetta team to make something similar to Valve’s Proton to actually get the games running on Mac once and for all.
Repairability and upgradability, for real. No ridiculous tools. Stop with the parts pairing. etc.

Real intelligent human support for advanced support issues. The real genius bar for us nerds who need it.
Fix the documentation. You like to brag about being best in the world at so many things. Why isn’t your documentation best in the world?
Let Apple Watches work without iPhones. Better yet, let them work with Android phones. Better yet, let iPhones work well with smart watches that aren’t Apple Watches.
I could go on, but I think that’s enough.
