Hi Fjskajbbdiwjs,
Thanks for posting! As we understand it, you're running into some issues using Minecraft on your Mac. Reinstalling the app was a great starting point. While this might be a case where you'll need to work with the app developer, we'd like to share this link with a few steps you might not have tried yet If an app freezes or quits unexpectedly on Mac:
"When an app on your Mac stops working, try these suggestions.
- If an app doesn’t quit as expected, or it’s unresponsive, you can force quit the app (you may lose unsaved changes). Choose Apple menu
> Force Quit, select the app in the dialog that appears, then click Force Quit. - If the app quit, reopen it by clicking Reopen in the dialog that appears.
- Restart your Mac by choosing Apple menu > Restart.
- Make sure the app is compatible with your version of macOS.
- Open another file in the app. There may be a problem with the original file.
- Check for updates to your software.
- Disconnect any peripheral devices you just connected (for example, a printer). They may not be compatible with your version of macOS.
- Uninstall any app plug-ins or enhancements from other manufacturers.
- If you recently updated the app or macOS, a plug-in or enhancement you installed may no longer be compatible.
- Diagnose problems on Mac to learn whether hardware you installed, such as additional memory, is incompatible, improperly installed, or defective."
If that doesn't help, we'd recommend contacting the developer for next steps: How to contact an app developer - Apple Support
Take care.
