So on Friday, Augut 15, 2025 I emailed the boss about the provenance of the 2015 MBP that work issued to me in 2019. This Mac, the subject of this thread, was 'retired' in mid-2023 in favor of our current M2s.
I'm glad I asked. I was told not to update this Mac by the guy who was essentially the company's IT department (he died during COVID), so it's been sitting on High Sierra since I got it. And it turns out that they DO expect it back. So, not mine to keep.
Which is fine. I'd much rather have it this way then to
THINK it was mine when it's not. I've removed all the stuff I installed, plus my data and disconnected it from iCloud (which is actually a work Apple ID I created, not my real Apple ID). Of course, pulling it out from the rat's warren that are all the cables behind my desk ended up removing power from one of the adapters for the Cinema Displays. Had to trace that down, but the Mac is out (as is the power adapter) and sitting on my desk. Got to figure out now when I will next be down around Mesa, AZ (where the office is) so I can take it back.
Not mine, not using it, I don't want it here. That sounds snarky, petty and hostile, but it's not. It's just that it's sitting there ON all day everyday sucking up juice and taking a precious power slot I could use for something that IS mine.

It's doing nothing and since it isn't mine I can't use it for what I want, so I want it out.
That's the way it goes. G'bye Miss Independence, when you worked right you gave good service!
PS. The MBA on the top right is mine.
