What to do if you forgot your Mac iOS passcode or your device becomes disabled after entering wrong passcode.

This handy link to Apple support has been very helpful when one of my precocious middle-schoolers decide to passcode protect an iPad on our iPad cart.  It is still a nuisance but this helps make it a little less painless, especially if you have an up-to-date back-up of the iPad in iTunes.  Also do not skip over the tidbits of information halfway down the page under the heading "If you have never synced your device with iTunes, or you do not have access to a computer".  Click the triangle to the left to un-hide some tips and button combinations they may help you in this situation.
