I’ve been intending to sketch out my whole synchronization scheme which keeps multiple applications synched between two Macs and the rest of the world, but it is so complicated that just documenting it has made me want to rethink. In the interim, I noticed yesterday that a bunch of changes that I had put into my address book on the MacBook didn’t get synched to the iMac, and after a lengthy chat with Apple’s MobileMe tech support the answer appeared to be nothing more than logging out of MobileMe on the laptop and then logging back in.
One trick with synching with MobileMe is to strip down the applications, so that you are only trying to sync one thing at a time when troubleshooting. Right now I’ve only got the contacts synching.
If one forgot that you can actually log into your MobileMe account from a web browser, one should be reminded of that helpful suggestion, as you can check whether your sync changes reach the the “cloud”. Obviously (in hindsight) if you make a change in iCal on one machine, and do a sync, the changes should appear in the copy of your files in the cloud, before any other machine can sync and download the changes.
