Bad Safari Issue
To fix something earlier I had to get rid of the Safari cache and get it to redo the cache from scratch. In the process that got rid of all the “Keep me signed in” stuff for all the accounts I had at various websites. When I tried to sign-in again, all those sites said that I was already signed in, though I wasn’t. This meant, though that I will need to create new accounts for myself at these sites (luckily none of them are that important). The real problem is that this means that when switching to a new mac, I’ll have the same problem, and so will all of you. The real trick is not to keep yourself signed in at any website anymore.
