OK, I think I posted this a few weeks ago, but not solution was reached, and I lost track of the thread. My MBP (10.11.6) is on a network with other Macs with the same OS. When I did a Network connection to it, from my other Macs, many folders in my user folder were marked as being inaccessible. Now, my login name is the same on all machines, and these folders ALL had permissions set so my login should have R/W permission. Those folders are in my account on the MBP. Weird. I finally figured out that, in order to access those files and folders, I needed to give Administrator R/W permission to each of them. Now, no one is logged in as Administrator either on my MBP or my other machines, so that seems odd. In fact, my login is not marked as having Administrator privileges on any of these machines. The question is WHY? When memyselfandi logs into my MPB, why do I see loads of folders owned by memyselfandi that are marked as being inaccessible? Why does giving Administrator permissions to those folders make them accessible?
