Trying to find out why my 2012 11" MBA on 10.13.6 won't wake(*). This is a fresh install of High Sierra, I have done the SMC and PRAM reset thing, 'Wake for WiFi Access' is unticked... (*At first I thought it wasn’t going to sleep, but the log at 12:22:05 seems to show it is sleeping - although the sleep key-combo doesn’t work… Also, maybe ‘Drivers failure’ at 12:47:39 is a clue to not waking?) On start up I have to hold the power button for about 3.5 seconds for the chime. Release the button too early (within say, a second or so of hearing the chime) and it just shuts back down. Then there is a second boot chime (it double-boots).
I bought this as "sluggish starting up" without an SSD. Originally I had to delete a kext to fix the awfully laggy behaviour. I tried installing Mojave and then El Cap but neither worked. The laggy behaviour returned a couple of times as the kext was recreated due to OS updates. I kept removing it and that kept fixing the problem - until I randomly decided to put it back and the laggy behaviour didn't return... Go figure. Oh - and the not-waking thing pre-dates the kext removal (and I've also renewed).
EtreCheck says:
Major Issues: SIP disabled (*not any more). Apple security disabled.
Minor Issues: No TM backup. High battery count. Vintage hardware. 32-bit Apps.
