[QUOTE="krs, post: 1944876, member: 67742"] I'm sorry - I was off by one with the 10.x release numbers. I usually use the macOS names and shouyld have stuck to that. Yes - the 2017 MBa came with 10.12 but to keep the user on 10.11 (El Capitan) I decided after some research that this should work and it did. Two comments: 1. El Capitan (10.11) ran on that 2017 Mac from 2018 until now with no problems - so "retrograding" from 10.12 to 10.11 was not an issue on the 2017 MBa, and 2. I never installed 10.13 on that 2017 MBa; it only ran with 10.11 If APFS was only introduced with Sierra (10.13), then anything related to APFS is a red herring. Confusion started when I posted the wrong macOS versions. A bit of background how the problem started: Two days ago in the morning, the 2017 MBa (running 10.11) would no longer take a charge. No light on the Magsave connector. Tried another Apple charger - same problem. Tried both chargers on a different MBa - both worked fine Checked battery cycles - just over 200 At that point the MBa booted fine; battery was at 45% So to see if I could coax thge charging back to life, I did both a PRAM and SMC reset PRAM reset first - MBa booted up but would still not charge Then the SMC reset; still no charge but now the boot process got stuck at about the 2/3rd point of the progress bar. Seems that trying the SMC reset may have corrupted the SSD - or just coincidence? DU reported that it can't fix the issue because it can't write to the SSD but it can still read the SSD That didn't help much because the Mac is running out of battery power. So....next step is to get another 2017 MBa (with no powere issues}, move the SSD from the problem Mac to the "other" MBa and try to recover any files. The SSD in the 2017 MBa is 7 years old, I'm not sure I want to use that again. Is there any info re life expectancy of SSDs? As to erasing the drive and installing the files from the back. If the backup were current, I would have done that rather than trying to jump through hoops with the corrupt SSD. Unfortunately the backup is several months old - but if all attempts to recovewr data from the corrupt SSD fails, that's the back up I will have to use. [/QUOTE]
