Earlier this week, Apple released updates for iOS, iPadOS, and watchOS—but nothing for macOS.
The Catalina update is a modest one that fixes three bugs: a graphics-related problem on new iMacs with Radeon Pro 5700 XT graphics cards, a bug that prevented automatic connection to WiFi networks, and an iCloud Drive syncing issue.
macOS Catalina‌ 10.15.7 provides important security updates and bug fixes for your Mac.
The updates to Final Cut Pro X and iMovie are also about fixing bugs.
The iMovie update improved stability and fixed an export bug
Yesterday, Apple also released an update for Xcode that fixed a problem that could "cause Xcode to crash while viewing documentation."
