Apple Releases macOS Catalina 10.15.7 Supplemental Update With Security Fixes

by

Apple today released a supplemental update for macOS Catalina 10.15.7, introducing security fixes. The macOS 10.15.7 Supplemental Update comes more than a month after the release of macOS Catalina 10.15.7.

Catalina10
The ‌‌‌‌macOS Catalina‌‌‌‌ 10.15.7 Supplemental Update can be downloaded from the Mac App Store using the Update feature in the System Preferences app.

According to Apple's release notes, the Supplemental Update improves the security of macOS and is recommended for all users. An Apple support document outlines several vulnerabilities that that have been addressed, including those that leave the Mac vulnerable to malicious fonts and applications.

macOS Catalina will soon be replaced by macOS Big Sur, which is in the final stages of beta testing and could be released as soon as next week.

What if you're still on Mojave because it runs so smoothly and the endless stories of the dumpster fire that's Catalina are a deterrent not to update?

I think a lot of people are simply hating on Catalina out of habit now. It’s sad.

Why don't they have a minor version number instead of calling it a supplemental update?

I just updated and there is no way to tell whether or not the update actually happened.

Edit: [USER=1226255]@Unsupported[/USER] showed me ('https://forums.macrumors.com/threads/apple-releases-macos-catalina-10-15-7-supplemental-update-with-security-fixes.2265661/post-29169450') how to find it. That can also be found under
About This Mac -> System Report -> Software
But having a minor version number would be so much easier.

Catalina is a lot better than it used to be. Mojave will always be my fav since Snow Leopard though.

Mojave has anther year of security updates yet, no need to migrate to either of the disasters that are Apple's last two OS releases.
So, you pronounce Big Sur a disaster, even though it hasn't been released yet? Another very objective post on MR /s
