My MacBook has now frozen twice in the span of one week. The screen freezes on whatever I was working on, the trackpad freezes, and the keys do not input anything.

I’ve removed the back cover and gently dusted the inside using pressurized air, but the problem persists.

Here is an audio recording of the ticking noise in question: https://youtu.be/pQhUsNsF9dk

    As far as I know the ONLY thing in that model with moving parts are the fans, assuming it's not coming from the speakers. If the fans are failing then the system could be overheating and going into thermal shutdown. Well, that's my theory at least. – Steve Chambers Jun 26 at 0:49
  • That ticking noise is precisely 1 tick per second. Odd that. – IconDaemon Jun 26 at 0:57
  • @IconDaemon I find that strange as well. Most fan related noise issues have a more scratchy noise and do not have that tempo – Metallitron Jun 26 at 1:48
  • @Steve Chambers If the system was going into thermal shutdown, I don’t get why the screen stayed on, and FaceTime and my Excel spreadsheet were still displayed frozen. Really strange... I’ll open it up to see if there’s any fan damage. – Metallitron Jun 26 at 1:51
  • If I knew that it would have been an answer and not a comment. It is just a guess. Sorry no other ideas. – Steve Chambers Jun 26 at 1:58
