Sometimes it's infuriatingly difficult to get a Genius Bar appointment at your local Apple store. So if your Mac is on the fritz and you've got an important meeting to attend, what are your options? Ask a friend, or dive into some forums? How about asking for help on Twitter? If that last one appeals to you, good news -- Apple has set up an account today to facilitate just this sort of Q&A. Why it's taken so long to create is anyone's guess, but it's here now, so feel free to bombard @AppleSupport the next time everything randomly disappears from your iCloud account.
