Hmm, one strange thing is that the ALT key works at boot time. It needs to be held down in order to select the boot mode (Mac or Windows).

Booting to Mac, the keyboard allows input, but the characters are random, as though a character set that is all symbols has been selected.

Oh. Grrr. I've seen this with external Apple keyboards.

Something in macOS gets its knickers in a twist and refuses to see the Apple keyboard as a keyboard if plugged directly into the USB port. If it's plugged into a hub and that hub is plugged into the same USB port on the Mac it's happy. Then randomly it'll reset and you can plug the keyboard into the unit again until another random time.

I do wonder if the same thing has happened to your internal keyboard.
Intro retro computers since before they were retro...

Added code to the MiNT kernel (still there the last time I checked) + put together MiNTOS.

And it lives...

Though something certainly had it's knickers in a twist.

I did a PRAM reset (COMMAND+OPTION+P+R at boot) and it lives again. First time I've had to do it on this machine, but I'm back into MacOS and Windows just fine again. I'll do a bit of burn in testing before I resurrect it for workshop duties though, and I'm going probably get another PSU for it.

The PRAM reset seems to solve a lot of issues.

I once had weird artefacts all over the screen after having tried an emulator. Reset and power-off didn't help, but a PRAM reset was successful.

Yes, it definitely seems to fix a lot of unusual issues.

It was helpful in that it also made me do a thermal re-paste.

Well, bit of time this morning, so time to clean the desoldering gun. And boy did it need it!!

As I'm in a large run of desoldering (I'm replacing the single wipe sockets on the C128 for double wipe), it had got pretty gunked up and needed a fairly thorough clean and filter replacement.

All shiny now, ready for the next run of sockets on the C128:

I've got the 2 VIC's, the SID and one of the PIAs and a socketed LS to do, so the end is in sight. I have to say it's one of my favourite tools, it makes it so much easier and safer for through hole component replacement.
