I'm so bummed that the workarounds to keep a 5k iMac in commission all seem to be really likely to piss off your corporate IT department.

Patching the bootloader in memory seems like a big op-sec no-no.

Last time this came up on Hacker News, someone pointed out that there are new display boards you can buy from China to reuse a 5K's panel as an external display.

I think we're only allowed to run Linux at work on blessed devices. Last I looked, the 5K panel in the iMac was actually presented to the firmware as two smaller displays, which were glued back together in software. Apple does that magic to support its own hardware, but it sounded like Linux doesn't.
