Open and Save Dialogs Are Slow and Beachballing for Seconds

Hi adrian_s,

It sounds like you're experiencing performance issues with the Open and Save dialogs in macOS Sonoma. Here are some steps you can try to troubleshoot and resolve the issue:

1. Restart your Mac: Sometimes, simply restarting your Mac can resolve temporary performance issues. Try restarting your Mac and see if the problem persists.
2. Reset the NVRAM/PRAM: Resetting the NVRAM (Non-Volatile Random-Access Memory) or PRAM (Parameter RAM) can sometimes resolve issues related to system settings. To reset the NVRAM/PRAM, restart your Mac and immediately hold down the Option + Command + P + R keys until you hear the startup chime for the second time, then release the keys and let your Mac continue booting.
3. Check for software updates: Make sure that your macOS Sonoma installation is up to date. Go to the Apple menu > About This Mac > Software Update and install any available updates.
4. Check for third-party software conflicts: Sometimes, third-party software or utilities can conflict with system processes and cause performance issues. Try disabling or uninstalling any recently installed third-party software to see if it resolves the problem.
5. Reset user permissions: Resetting user permissions can sometimes resolve issues with system services. You can reset user permissions by booting into Safe Mode, as you mentioned it doesn't happen in Safe Mode, or by using Disk Utility to repair disk permissions.
6. Create a new user account: If the issue persists, try creating a new user account on your Mac and see if the problem occurs in the new account. If the issue doesn't occur in the new account, it may indicate a problem with your user account preferences.
7. Contact Apple Support: If none of the above steps resolve the issue, you may want to contact Apple Support or visit an Apple Store for further assistance. They may be able to provide additional troubleshooting steps or recommend further action.

By following these steps, you should be able to troubleshoot and resolve the performance issues with the Open and Save dialogs in macOS Sonoma.

Good luck!

Greetings
