MacRumors spotted a bug report that affects the current version of macOS High Sierra. In System Preferences, you can unlock the App Store preference pane by typing any password. Apple has reportedly already fixed the bug in beta versions of the next macOS High Sierra update.

While this bug is nowhere as serious as the infamous root login bug, as John Gruber wrote, this one is quite embarrassing. What’s wrong with password prompts and macOS?

If you want to test this bug at home, I was able to reproduce it quite easily. Open System Preferences, go to the App Store settings and look at the padlock icon. If it’s unlocked, lock it first and then try unlocking it with any password. Ta-da!
