The parent commenter described exactly how Macs work. I have a beautiful 10-core iMac 27” with 72 GB of RAM from 2020 that Apple has now decided to turn into a lemon. macOS Tahoe runs as slow as molasses and no more macOS upgrades will be forthcoming. I downgraded to Sonoma (which cost me hours) and the machine runs well again for now but the App Store has already started refusing to update apps like Pages because macOS is old. Soon I won’t be able to install a single app through the App Store and Linux (T2 Linux in my case, not Asahi) will be the only option to keep using this terrific hardware.
