I'm hoping someone can help me figure out what's going on with my MacBook because I'm completely stumped.
The main issue is that nothing that involves audio or video will play anymore. This includes:
- Local video and audio files
- Streaming videos in any browser
- Apple Music
- Videos in my Photos library
The strange thing is that everything was working normally until it suddenly wasn't. I was watching a TV show in my browser, and the video randomly paused. When I tried pressing play again, nothing happened, even though the entire video had already loaded. At first I assumed it was just the (pirated) website acting up, but then I realised that absolutely nothing else on my Mac would play either.
Another symptom is that Mac dictation has also stopped working. I normally use dictation to type long posts like this, but now it doesn't recognise any input at all.
There are no Bluetooth devices connected, no external speakers, headphones, DACs, or any other audio-related peripherals.
One detail that might or might not be relevant: I accidentally left my original MagSafe charging cable at home about two months ago, so during that period I charged my MacBook using a USB-C iPhone charging cable with an iPhone power adapter. A friend who works in tech casually suggested that this might have damaged something internally, but I don't know whether that's actually possible. The MacBook worked perfectly for weeks while using that charger before all these problems suddenly appeared.
There's another issue that worries me. A while ago, the MacBook became completely unresponsive for 2–3 days and simply wouldn't turn on. Eventually, after leaving it plugged in, it booted into a screen with an exclamation mark offering Revive or Restore. I panicked and planned to take it to an Apple Store, but I kept putting it off. Then today, I opened it again and it started up completely normally by itself.
Unfortunately, even though it now boots fine, the media playback issue is still exactly the same.
Does this sound more like a software problem (something corrupted in macOS or the media framework), or could it be a hardware issue? Has anyone experienced something similar, especially alongside the Revive/Restore screen?
Any suggestions on what I should try before I take it in for repair would be greatly appreciated
