Hello!
I understand how frustrating it can be to have problems like this on such a powerful Mac. Since these blocks started with the update to macOS Sequoia 15.2, there is a good chance that there are bugs or software incompatibilities. Here are some tips to try and solve the problem:
1. NVRAM and SMC Reboot and Reset
• Restart your Mac: Simple but often effective.
• Reset NVRAM: Turn off your Mac, then turn it on and hold down Option + Command + P + R for about 20 seconds.
• Reset SMC: If you have performance issues, you may want to try resetting the System Management Controller (SMC). On your Mac with an Apple Silicon (M3 Pro Max) chip, just turn it off and wait 30 seconds before turning it back on.
2. Check for Software Updates
• Go to System Settings > General > Software Update and check for updates. Apple may have already released a patch.
3. Start in Safe Mode
• Turn off your Mac, then turn it on by holding down Shift until the login screen appears.
• This helps to isolate software problems, disabling third-party extensions and emptying some caches.
4. Check the Disk and RAM
• Open Disk Utility and run "First Aid" on the disk to see if there are any errors.
• Open Activity Monitor (from Spotlight) and check CPU and memory usage. If you see abnormal processes, they could be the cause of the blocks.
5. Problems with Finder and Safari
• If Finder crashes frequently, try deleting the preferences file using this line in the Terminal:
~/Library/Preferences/com.apple.plist.
Then restart your Mac.
• For Safari, clear the cache:
• Open Safari, go to Safari > Settings > Advanced and enable the Developer menu.
• Then go to Development > Clear cache.
6. Create a New User
• Go to System Settings > Users & Groups and create a new user. Log in with that and see if the problem persists. If it works well, the problem may be related to your main profile files.
7. Restore macOS Sequoia
If nothing works and the problem is unbearable, you might consider a clean installation of macOS.
1. Back up with Time Machine.
2. Restart in Recovery Mode (+R on startup).
3. Select "Reinstall macOS" and follow the instructions.
8. Report the Bug to Apple
• Open Feedback Assistant (already installed on macOS) and report issues to Apple.
• You can also visit the official Apple Feedback site to submit reports.
If the issue is caused by a bug in macOS 15.2, a future update may fix it. In the meantime, try these solutions and let me know if anything helps!
