Apple recently released a new upgrade for the operating system that runs on their mobile devices (iOS 5). This upgrade breaks compatibility with the OverDrive software on Windows computers. If any patrons have problems with their devices and request assistance with an Apple device and errors they’re receiving – this may be the cause.
OverDrive is aware of the problem and are working to fix it, but until an update for their software is available there are currently no solutions.
Apple mobile device users that simply use the OverDrive app downloaded from the iTunes app store should not experience any problems.
