I think this person actually wants to run linux, but they are using Mac as a test case.

They mentioned "install an alternative operating system" - which on hardware sold for Windows very much implies Linux.

But if Linux is a no, and even macos is a no - which is from a "big and proper organisation" with support agreements and everything - then the company is obviously a lost cause who are dead-set on windows for life for all time.

It's what happens if you submit a comment and fall for the egregious lie that is Lemmy telling you it didn't go through

Whoops. I commented, decided to rephrase and edited. But it didn't result in an edit and I didn't notice as that's when I went to bed.
