Hi! I see that Notability is crashing frequently for you while you're taking notes, about 4 times an hour. That sounds inconvenient. To help me tailor the solution better, could you tell me if this happens with all notes or just certain files? Also, do you use any cloud services like OneDrive or iCloud with Notability? Lastly, has this behavior started recently or been ongoing for some time?

Meanwhile, here’s a step-by-step approach to try resolving frequent crashes on your Mac running OS X 10.15.7:

1. Update Notability: Make sure your Notability app is updated to the latest version available in the Mac App Store. Sometimes, crashes happen due to bugs that updates fix.

2. Restart Your Mac: A simple restart can clear temporary glitches affecting app performance.

3. Check Cloud Services: You mentioned frequent crashes. If you have OneDrive installed and linked to Notability, try uninstalling OneDrive temporarily. There is a known issue where OneDrive conflicts with Notability files causing crashes or crashes related to the .notes files2.

4. Enable Safe Mode in Notability: This is a feature that disables some advanced capabilities to improve stability during performance issues like freezing or crashing. To enable, you might find it in Notability’s preferences or settings inside the Mac System Preferences → Notability (if available)3.

5. Clear Cache or Reinstall: If the issue continues, try deleting the Notability app and reinstalling it cleanly. Make sure to back up all your notes before uninstalling to avoid data loss.

6. Check System Resources: Ensure your Mac isn’t overloaded with other tasks consuming RAM or CPU, which can cause apps to crash.

Please let me know if you’ve tried any of these steps already or if you observe anything specific right before the crash, like adding certain media, handwriting, or syncing, so I can help further! Are you satisfied with this solution so far?
