For the third time since its introduction a year ago, Apple’s high-end file system (APFS) has fallen victim to a bug. The latest vulnerability affects macOS High Sierra, leaving the encryption passwords of users with external storage devices exposed in plaintext – and therefore wide open to attack.
Not all versions of macOS High Sierra are affected in the same way. Apple appears to have rectified the problem in recent versions, but it remains an issue with earlier editions.
While Apple generally acts swiftly to fix this kind of technical hitch, a trio of APFS misadventures in the space of five months is unlikely to enhance its reputation.
