Maybe we're being a little melodramatic by calling them life-threatening, but with every iOS or Mac bug comes an outcry from hundreds of thousands of Apple users. Take last week, for instance, when a Mac App Store bug caused several software updates to instantly crash apps once installed on both Macs and iOS devices. Apps included the popular Instapaper, GoodReader, Angry Birds Space HD Free, and even Readdle's Scanner Pro 4.1 update. Fortunately, the ordeal was over once Apple finally stepped in to quell the grief that had been caused over a few days, but this is not the first time that Cupertino has had to deal with squashing huge bugs. Take a trip down memory lane with us to investigate some other cases where Apple products have been plagued by nasty computer bugs.
