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.

    I have the same problem, but I thought some plugin was to blame. Are you using emacs-plus?
