A few months ago, when I upgraded to Mac OS X Tiger on my iMac, I chose to do the OS upgrade rather than the clean install. I mean, who wants to reinstall all their apps and try to remember all their settings and preferences?
All went swimmingly, except for the Missing Sync. As its name implies, it's a patch that deals with conflicts between between .Mac Sync (new), Apple iSync (old) and Palm OS for Mac (an unspeakable pain in the rear). With Missing Sync, I can keep the data that I already sync between my PowerBook, my iMac, and my .Mac online account, in sync with my Treo PDA as well.
It turns out that those of us who upgraded, rather than clean-installed, Mac OS X Tiger, locked deep into the system something that annoyed the heck out of the Missing Sync.
In my attempt to get Treo syncing to work again, I spent several annoying evenings downloading, uninstalling, reinstalling, and encountering "you do not have access to this file"-type messages. I found discussions of the Tiger-upgrade-hoses-Missing-Sync problem online, but, ominiously, none of them mentioned any solutions. The result was that my Treo hadn't been synced since July.
Trusting the people at the Missing Sync to address the problem (think about it, their whole product is based on addressing a problem Palm and Apple don't want to talk about) I kept checking back to their site. Sure enough, today I found a step-by-step solution. Of course, I'd already trashed, damaged, re-installed and generally mucked around with all the files and conduits involved, but I was able to follow their step-by-step about three-quarters of the way through, up to the point where it didn't make sense any longer. And at that point, being an experienced Mac user and trained to expect generally positive outcomes, I just pushed some buttons and leaped into the digital abysss.
The result? Synced again. I have no idea why it worked, but, once again, thank you to MarkSpace (that's the Missing Sync people) for putting out some signposts.
