When you assign an Apple ID to your user account, you have to verify it’s properly linked.

You can do so, by following these steps:

1. You can do so by going to the users & groups pref pane ;
2. Unlock it and right click on your user account ;
3. You should see “additional options” then. Go for it ;
4. Now take a look to the “Aliases” Section. You should see the mail adress of your linked Apple ID there. Right below there should follow a line, starting with “com.apple.idms.appleid….”. This seems to be some kind of Unique ID of your Apple ID.
5. If this entry is present, your Apple ID is correctly linked to your account. If there is only the mail adress, the linking was not successfull. In this case, make sure you have Internet connection. This is important, because the information of the Apple ID must be taken from Apple’s servers (if you link the Apple ID without Internet Connection, it will not work at all) ;
6. After you have ensured a working internet connection, remove and reassign the Apple ID to your account.

When you have done this on both computers, you now should be able to connect a remote computer using your Apple ID.

But only for file sharing.

Screen Sharing seems not to work this way at the moment.

Just visit this page and follow the steps: www.me.com/move
Don’t forget to update your OS (Mac OS Lion 10.7.2) and your iOS (version 5) prior to perform the move.

And again…

Thank you Steve…

No more Mail.app hogging your bandwidth with this incredible trick for OS X.
This will only work if your server supports IDLE (like MobileMe, Gmail…).
3 steps to make it work:

1. Go into Mail » Preferences » Accounts (Advanced) and make sure that Use IDLE command if the server supports it is enabled (it’s enabled by default).
2. Go into Mail » Preferences » General and set Check for new Mail to Manually.

Now send yourself a new message (preferably from a different account) and watch the fun.

An error message that I don’t wish none of you to meet, but it’s happening to me these days on two Mac’s.
This post comes after the one I announced in the OS X update, not sure it’s OS 10.5.6 but I have some doubts on that.
Solution 1 is the following:

1. Turn off iDisk Sync (click the Stop button in the iDisk pane of MobileMe preferences, in System Preferences).
2. Restart your computer.
3. From the Go menu, choose Home.
4. Open the Library folder.
   • For Mac OS X 10.4 or earlier: Remove the Mirrors folder
   • For Mac OS X 10.5: Remove the FileSync folder
5. Restart your computer.
6. Re-enable iDisk Sync.

A lot of users are disappointed.. Is this new service is working or not? While some are flexible some others are aggressive toward this unique service.
I’m from the moderate ones that think every new technology needs some time to be perfectly working, and I do not blame Apple for MobileMe’s problems.. after all, I had .mac!
First reaction, Apple decided not to use the word “push” anymore for the “over the air” synchronization of our datas.
Second reaction (that came with the first one), is a bonus of 30 free days offered to all of us MobileMe users (I’m still waiting for my MobileMe pref pan to be updated though)…
And finally, Steve Jobs, himself, decided to react and asked someone to write a post on Apple.com.
This page is there to inform MobileMe subscribers on the progression of MobileMe.
So… please, be patient, it’s not as if Apple is ignoring us!

A lot of people are complaining about the fact their iPhone isn’t receiving anything from the MobileMe cloud; and I was one of them; but I finally managed and it is now up and working!
Here are the steps I followed to make my iPhone sync my data “over the air“:

1. Sync the iPhone and uncheck the email sync (in iTunes)
2. Open mail.app and deleted my .mac account
3. Setup a “brand new” mobileme account
4. Sync from system preferences the datas (contacts, ical etc)
5. Sync the iPhone and check the MobileMe account (in iTunes)
6. Went to the iPhone and set it up (pref>general>mail, contacts…) to sync these datas over the air
7. (I saw) the contacts names appearing instead of their phone numbers in the recent/missed calls and on the SMS received and sent but still nothing in my address book
8. Restart the iPhone: everything is there!

I still don’t know which of these steps made the “thing” work though…

Another update, this one will completely remove all the traces of .mac from your Mac.
iLife Support, iPhoto, iMovie, and iDVD will now show that little cloud instead of the .mac logo.

Still nothing for Aperture and … keychain; but I guess it will be out soon (in a Leopard update I guess).

Another snag we have run into is our use of the word “push” in describing everything under the MobileMe umbrella. While all email, contact or calendar changes on the iPhone and the web apps are immediately synced to and from the MobileMe “cloud,” changes made on a PC or Mac take up to 15 minutes to sync with the cloud and your other devices. So even though things are indeed instantly pushed to and from your iPhone and the web apps today, we are going to stop using the word “push” until it is near-instant on PCs and Macs, too. 

Apple also rewards us with a 30 day extension to MobileMe, I’m eligible yay!
