macOS High Sierra Logs Encryption Passwords in Plaintext for APFS External Drives (bleepingcomputer.com)

Catalin Cimpanu, writing for BleepingComputer: macOS High Sierra users are once again impacted by a major APFS bug after two other major vulnerabilities affected Apple's new filesystem format in the last five months. This time around, according to a report from Mac forensics expert Sarah Edwards, recent versions of macOS High Sierra are logging encryption passwords for APFS-formatted external drives in plaintext, and storing this information in non-volatile (on-disk) log files.

The issue, if exploited, could allow an attacker easy access to the encryption password of encrypted APFS external volumes, such as USB thumb drives, portable hard drives, and other external storage mediums. This bug goes against all well-established Apple development and security rules, according to which apps and utilities should use the Keychain app to store valuable information, and should definitely avoid storing passwords in cleartext.

      Before Jobs' death you could tell when he was sick and not able to do as much, the bug count on new product/software releases seemed to be much higher and more pronounced. At least it sure seemed that way.

      I don't know why this seems to be the case, but the pattern seems to hold, even more so after his passing the releases seem to get a little further and further away from the standards Jobs set.

BUT then rather than spend the fortune their stupid users fork over to them (as they have in years passed,) making an at-least halfway-decent product, they now spend it building fancy headquarters buildings, paying their executives obscene pay and benefits, and treating you like the moron you are for buying their shit.
