Unfortunately, my office suffered a power surge recently and I lost some equipment; modem, dongles, switcher, etc.
However, my M1 Macbook Pro survived. It works fine except it has issues with anything to do with audio and video, that is, I can't play any audio or video.
For example, I can't play a quicktime, mp3 file, or even watch a YouTube video. There's no sound and the videos won't play.
I also can't open any software that is audio/video related, e.g., Premiere Pro, After Effects, etc. But I can open up other software, like Microsoft Word.
Clicking around in the Sound panel in system preferences can be somewhat unresponsive too.
Any ideas?
Thanks in advance.
you run the user Diagnostic...not as definitive as Apple's own AST2 (Apple Service Toolkit) back bench diagnostic, but may kick out an error code.
Use Apple Diagnostics to test your Mac
Use Apple Diagnostics to test your Mac - Apple Support
If you rule out hardware
To trouble shoot further you can:
—Try a SafeBoot How to use safe mode on your Mac - Apple Support
Takes noticeable longer to get to the login screen, does a 5 minute disk repair before it fully boots up, and certain system caches get cleared and rebuilt, including dynamic loader cache, etc.
Login and test. Reboot as normal and test. Caches get rebuilt automatically.
In Safe mode third party system modifications and system accelerations are disabled, it removes malware, etc hampering smooth operation, however a reboot will put it back to normal mode.
This test will tell you if third party interference; extensions etc are not loaded in safe boot mode.
—Test issue in another user (or guest user) account Set up users, guests, and groups on Mac - Apple Support
This will tell you if it a universal issue or isolated to your user/admin account.
Uninstall all third party apps that are Cleaners/Optimizers/VPN/Anti-Virus
all known to cause issues on the macOS
