Why won't the Notes app open on Mac?

Notes is a simple notes application, supporting lots of file types and synchronizing between devices using Apple's iCloud service. So it will be pretty frustrating to access the files from your iPhone or iPad on your Mac when the Notes app won't open on your Mac.

The reasons for this issue vary from the app itself to your Mac system. Here are some of the most common reasons:

  • Notes app malfunction
  • The configuration file of Notes is corrupted or destroyed
  • The permission of the Notes app fails
  • Operating system glitches or bugs 
  • Not enough space available
  • iCloud synchronization problems
  • Too many apps working meanwhile
  • Conflicts between other apps and the Notes app
