The weekend was spoiled by my MacBook Pro: it had gone to sleep at the office, woke up at home, and a few seconds later froze solid. Had to do a hard reset.

The OS refused to boot — neither from the main partition nor from the Recovery HD partition that OS X Lion creates for restoring/reinstalling the system. Although the MacBook could see both partitions. I managed to boot from a USB stick.

My first thought was something wrong with the hard drive — either partitions had detached or the disk was dying. I pulled the drive, hooked it up to my second Mac via a USB enclosure. All files in place, no signs of trouble. OK, I figured, time to reinstall macOS from scratch — looked like a software glitch, those upgrade-from-previous-version updates can be flaky.

Backed up everything, ran Disk Utility’s repair, it fixed something I didn’t understand. Stuck the drive back in — decided to try booting from it — and lo and behold, everything worked. I breathed a sigh of relief, shut down, started up, slept the laptop, woke it — all fine.
