Foxbat, Jr., dropped off his old 2011 MacBook Air which was dead as a doornail because the MagSafe1 power brick died. I had pulled it out of storage the other day, thinking I might just take it to Apple to be recycled. The problem was it being dead, he didn't have a chance to wipe off his profile or data after he had migrated to his new MacBook Pro.
Anyway, I had picked up a cheap little dongle from Amazon that uses a standard USB-C power cable and PD USB-C Power Brick to plug into the dongle's Type-C connector to the original MagSafe connector (now known as MagSafe1). It's a much more affordable solution since I saw Apple 45W MagSafe1 power supplies were ~$70. I connected it to the MBA and got the "Happy Mac" sound. The PD power brick I got has a power indicator and I saw it was drawing 40-43 Watts.
I booted into the Apple Hardware Diagnostics utility and everything tested good. I booted up into Recovery Mode and after verifying with Foxbat, Jr. that there weren't any files or data he wanted, I erased the macOS partition and the TimeMachine partition (yes, I know it was a bad configuration, but at least he had backups while he was using it). When I went to install High Sierra, however, I got stymied by this:
Fortunately, Google to the rescue, by searching this image Google found an article at StackOverflow that explained how to fix this problem, and yay, it worked out for me. So, last thing was a PRAM reset (being an Intel processor) to wipe the last vestiges of any personal information from this machine.
Boy, I don't miss the Intel processors. As it was updating the OS, the fans were going gangbusters to keep it cool. I don't think I've ever heard the fan in my M4-powered Air, and the M3 MacBook Pro I had a few years back would only run the fans when decoding complex video streams, which wasn't very often.
But, this Late 2011 MacBook Air was pretty easy to work on. I had used it for my work and Foxbat, Jr., inherited it for his College years after I replaced the battery and upgraded the SSD to 480 GB. Unfortunately, Apple stopped support for these and any 3rd-party browsers have likewise moved on and won't support High Sierra. Time to install Linux…
