Howdy all. I’ve developed an issue with my MacBook Air (2012 model) in that it is operating painfully slow. Booting up takes far too long, and the fan comes on when normally it doesn’t. When I finally get to the login screen, there is lag in typing keystrokes and cursor movement. When it does log on, the UI loads slowly, as do the startup items. I’ve given up on trying to get fully logged in and running since it obviously won’t be usable.
I am able to boot from the recovery partition, and did an internet reinstall of macOS (current version of High Sierra). This didn’t help. I tried running the Apple Hardware Test, but that failed to run (sorry, I forget the exact error). I’ve reset the SMC and NVRAM, all to no avail.
At this point, it seems I have a hardware issue of some sort. A software related one just doesn’t make any sense at this point. My best guess right now is the battery. The last I checked with Coconut Battery, the capacity was about 75% of new. To me, the extreme sluggishness is akin to, say a toy with drained batteries. Any thoughts? Like I said, this came on rather suddenly. It was working fine last week, last used during Hurricane Florence (yeah, I’m in ground zero), but it wasn’t plugged in when that started up nor was it when we lost power. It was last used to charge our iPhones but worked normally before that point. It was recharged after normal, stable power was restored. My first attempt to use it since was yesterday. Only other guess is humidity got to something on the motherboard that regulates the power.
