macOS High Sierra 10.13 Supplemental Update

Every update we are used to seeing a new issue of the software / system version.
Apple it uses exceptions, and for the latest version of the operating system, macOS High Sierra 10.13 comes with one update additional without changing the version number.

macOS High Sierra 10.13 Supplemental Update contains a cumulative update that resolves a number of errors present on macOS High Sierra. Solve it graphics issue for Adobe InDesign and another related to sending emails from Yahoo accounts.

This update also solves two major security problems which appeared with the launch macOS High Sierra.

The first security issue It's about encrypted volumes APFS. The encryption password for an APSF volume could be read by anyone at "Hint". Instead of the phrase or help word appearing to give us clues about the password, the password appears directly in the text. Very easy to find out from Disk Utility.

The second security issue threatened everything passwords stored in Keychain Access. A malicious application could access it Keychain skipping the access password. In this way, all web addresses and authentication devices, usernames and passwords were discovered.

Updateis available via  App Store, in the tab "Updates”And has approx 950 MB.
