Mac users really struggle to understand the concept of

For me, it was trying to explain to a Mac user that she should have a separate profile on her Mac for work vs. personal

She'd convinced her employer that she could work from home using her own Mac (the office was all Macs except for the video production suite), and he said OK. Didn't ask me, of course. Despite me saying a long time ago when someone else floated the idea, that it was poor practice from a security viewpoint.

Then three days later the call came - "I can't access work files". So I remote in, she's got links to her personal iCloud Drive directories somehow mixed up with the work Google Drive.

I started to explain about using a different profile for work and just got a blank stare.

"You log off your personal profile and log into the work profile"

"How do I do that?"
