The dictionary on my MacBook Pro keeps freezing...

Hello Enyioma,

Thanks for that info and for choosing the Apple Support Communities. If I understand correctly, you are having an issue with the Dictionary app on your MacBook Pro being unresponsive and not working as expected. First, try running First Aid on your hard drive with the built in Disk Utility tool, as this can correct simple issues like you're experiencing.

Disk Utility for Mac: Repair a disk using Disk Utility

Next, use safe mode to start up your Mac as it does the following things:

• Verifies your startup disk and attempts to repair directory issues, if needed
• Loads only required kernel extensions
• Prevents Startup Items and Login Items from opening automatically
• Disables user-installed fonts
• Deletes font caches, kernel cache, and other system cache files

Log in to your user account and test the issue while in safe mode and then restart normally and test the issue again.

Use safe mode to isolate issues with your Mac

Cheers!
