UPDATED 9:30PM
Today Apple released the 6th Supplemental Update for macOS Catalina. With the release of 10.15.7, we thought Apple would continue with an easy way to identify updates. The 10.15.7 Supplemental update seemed to dash those hopes. The update does not even list any fixes in it. The only wording is
“macOS Catalina 10.15.7 Supplemental Update is recommenced for all users and improves the security of macOS”
This tells us that the update only has security related fixes in it!
In the security link, Apple calls out 3 security vulnerabilities. I will go over them below.
The macOS Catalina 10.15.7 Update includes the following Security fixes.
macOS Catalina 10.15.7 Supplemental Update provides important security updates for your Mac.
This update is an important update due to this quote from Apple
A malicious application may be able to execute arbitrary code with kernel privileges. Apple is aware of reports that an exploit for this issue exists in the wild.
Apple- The Supplemental Update patches the following
- FontParser arbitrary code execution = Found in the wild!!!
- Two Kernel Exploits = Both found in the wild!!!
- All three vulnerabilities have been reported to Apple from the Google Project Zero Team.
Treat this Supplemental Update as a High Priority!
Confusing Update Situation
We have a couple update scenarios that we need to discuss. Normally Apple releases new Delta and Combo Updates. This time we only have a delta update for 10.15.6 users. If you have anyone on 10.15.0-10.15.5 they will be offered the OLD 10.15.7 (19H2) Update. They will have to install the 10.15.7 Supplemental Update after!
- 10.15.7 users = NEW 10.15.7 Supplemental Update
- 10.15.6 users = NEW 10.15.7 Delta Update
- 10.15.0-10.15.5users = OLD 10.15.7 Combo Update – Will need to install the 10.15.7 Supplemental Update after.
- 10.15.7 Full Installer = Remains OLD 10.15.7 (19H2) version and will need to install the 10.15.7 Supplemental Update after.
