I had updated to sonoma earlier today on M1 MBA. Emacs became laggy, scrolling through my config file turned into a choppy mess.
After downgrading back to Ventura, all performance issues were fixed.

How to downgrade (in case anyone needs this in the future)

  1. Create Bootable USB Installer and download older macOS version from app store

  2. Make a time machine backup

  3. Reboot into startup options

  4. Wipe existing drive, install OS from usb

  5. Transfer files from time machine backup.

One thing I do after any major OS upgrade is, I update XCode, command line utils and rebuild emacs. Usually that fixes problems 99%. Of course it takes 1-2 hours to complete this process but I multitask during this time.
