This is such a hilariously American post. I realize most of this forum is American, but still. :-)
Well you said personal MacBook, this topic is about work laptop or phone.
These days (sadly) for any non-small company, all work computers and phones have remote control spyware. If you think that's not the case in your large company, you're probably wrong.
At a recent medium size engineering company, I was constantly surprised how even extremely technical engineers in the company didn't realize all the company spyware that is running on their laptop.
I do have MDM on my personal iPhone but that seemed like a reasonable tradeoff in order to easily access work email and files on my phone.
