So, with 10.5.2 and SuperDuper 2.5 out, I was finally willing to upgrade my primary Mac.

First problem: it merged down an old version of my Safari bookmarks from .Mac, even though I had sync turned off, and the last sync had reset this machine as the master. Fortunately, it was a merge, rather than a replace, so I didn’t lose anything, and only had a small amount of cleanup to do.

Second problem: I can’t turn .Mac sync back on to reset the bookmarks, and it falsely thinks that I’ve got local iDisk sync turned on as well (something I used to use a lot, but shut off a while back due to .Mac flakiness). The whole .Mac connection seems pretty hosed, actually.

Third problem: Mail.app’s IMAP insists on showing my entire home directory on one of my servers, and walking the tree each time to check for “new messages”; this behavior cannot be overridden from the GUI. It also completely lost track of how to connect to my primary SMTP server, but after the third try I was able to get it to send mail again.

[this doesn’t include the many problems I already knew about from upgrading other machines, of course…]

[…and I’m sure I’ll find more…]
