Just a general reply this, but I had to click on 'Reply' to someone's post...
It strikes me as very strange that something with such devastating consequences is even provided as an option in Finder. How many posts have there been saying "Help, all my settings/docs/music have gone!" or similar, and the poster having to be walked through the remedial steps? What useful purpose can there be to being able to rename the 'short name', and therefore the 'Home' folder, with a control-click?
Dr Smoke has a 'Recovering from Re-naming you Home folder', and presumably there is a Knowledge base # for it too. Surely the simplest thing to do would be, in a future SW Update, to remove that Finder option entirely. If it's necessary for some diagnostic purposes to rename, then let there be a more arcane way of doing it, surely.
Just my humble opinion, of course...
& yes Jon, my reply to Ozzman was curt, unhelpful and non instructive. I apologise for that. It was late & I'd been up since 5am. I should have left well alone if I wasn't prepared to more helpful.
An Apple a day... 😉
