MacBook Air with hi-speed fans and pfm006 ppn001 message
all of a sudden yesterday my Macbook Air 13" I5 started having loud fans and being a bit jittery.
This is what I did:
- reset PRAM and SNC
- cleaned system cache
- cleaned login elements
- rebooted in recovery mode and checked disk (HD was not mounted) >
- managed to mount HD and run repair, after that volumes looked all ok
- run diagnostics and then it gives pmf006 and ppn001 (plus ppt002 - low life battery) messages
No spillage has happened, nothing stranger than usual.
Logic board was changed by Apple in Dec. 2021
By running Acitvity Monitor the CPU load lies at max 60% (mainly kernel_task) and the temperature is 42/43°C...
macOs is Mojave 10.14.6
I am scratching my head. Anyone has some suggestions on what could be the issue here and how to fix it? I'd be extremely appreciative of any hint or tips!
Thanks a lot Dan...here are the screenshots from both apps
