I restarted the iMac and nothing
I then told the MBP to sync and got an error telling me it couldn't sync do to inconsistencies in the calendar. Of course there are inconsistencies. One calendar has one more item that the other
That is what sync is for. So...
I went in and unregistered the computers, registered them and then deleted the info on .mac and reset it all up and synced - mac to .mac and .mac to MBP. zilch , nada nothing and I can't get into the calendar at the mobileme website to see if it even got that far. It takes me to the mail page and when I click on the calendar icon it asks me to sign in and and then times out to the page not found error. I also get a white page that says unauthorized in the top left like it was typed by an old remington. I think I might just need to wait til tomorrow and see if it calms down.
Tismeinaz, I think I read in one of the announcements that the transition may take up till the 24th to complete fully. So if I were in your shoes I wouldn't try to force the matter at this time. It might be best to set it as it's supposed to be set then wait and see if it straightens up as time goes by. If by the 24th things still aren't working right, then I'd start tinkering with the configuration again.
Did you get an update for "Mac OS X Update For MobileMe" (1.1)?
May help to run Software Update, too.
Oops, I hadn't read page three before replying to this post. Not enough sleep lately. But it's still good advice for others to check.
