Back to Your Mac

I use a MacBook Air for work, which keeps my backpack light. I’d like your recommendation for software that will let me access my iMac at home from the MacBook Air. I just want to access the iMac to retrieve a file, maybe an email, and that’s it. I know there’s LogMeIn and Back to My Mac (I’m a MobileMe subscriber), but I’d appreciate your expert opinion.
Thanks for the compliments, but we’re actually on the same wavelength. If you already subscribe to MobileMe and you’re not using Back to My Mac, you’re not getting your money’s worth, we’d say. It works well and it’s dead simple to use. Head to System Preferences > MobileMe, click to the Back to My Mac tab, and turn on the service on both your home iMac and your MacBook Air. While on that screen, click the Open Sharing button to open the Sharing pane of System Preferences, and turn on both File Sharing and Screen Sharing. To make sure only you can wield these powerful technological swords, use the Allow Access For menus to make yourself the only allowed user--click the plus sign to add a user, select Users And Groups in the left pane of the pop-up window, and choose your own username.

Turn it on, and it just works.
Now when you’re in the wild blue yonder, you can open a Finder window on your MacBook Air, expand the Shared section of the sidebar, and there’s your iMac, waiting patiently. (Well, provided it’s turned on back at your house and connected to the internet via your home network, and your MacBook Air has an internet connection too.) You can click on it to start the connection, log in with your iMac’s username and password, and then see all your iMac’s files, open ’em, move ’em around, drag them over to your MacBook Air, whatever. If you have a Time Capsule on your home network or an AirPort Extreme Base Station with an external hard drive attached, those files will be available to you too.
If you want to see your iMac’s screen, say to launch your email app and read messages, find your iMac in your MacBook Air’s Finder window, then click the little Screen Sharing button that appears, and you’ll get to see the iMac’s screen and control it as if you were a ghost or something.
LogMeIn is cool too (see “Trick Out Your Menubar with 10 Free Apps”), especially for non-MobileMe subscribers. If you just want to see and control your iMac from the MacBook Air, LogMeIn Free will work just fine. But if you want file transfers, you’ve got to upgrade, and LogMeIn Pro for Mac is in beta at press time ($12.20/month or $69.95/year per computer, logmein.com).
So we recommend trying Back to My Mac since you’re already paying for MobileMe (other readers, remember that MobileMe has a free 60-day trial), and if it doesn’t fit your needs somehow, try LogMeIn. But we think you’ll get a more seamless and Mac-like experience with Apple’s product--that Finder integration is something only Cupertino can provide.
