Earlier this week, Apple released updates for iOS, iPadOS, and watchOS—but nothing for macOS. Usually, Cupertino updates all its operating systems at once, but we're in an odd place right now with new annual releases of the former three making their way to users' devices while macOS Big Sur still sits an indeterminate amount of days away.

However, Apple nonetheless followed up today with an update for macOS Catalina labeled 10.15.7. It's likely the last update to Catalina before Big Sur is released. The company also released new versions of Final Cut Pro X and iMovie for the Mac.

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.

Apple has released software updates for three of its operating systems: iOS for iPhones and iPods, iPadOS for iPads, and macOS for Macs. The updates are small and focus on bug fixes rather than adding new features.

The updates are labeled iOS 13.6.1, iPadOS 13.6.1, and macOS 10.15.6 Supplemental Update. Typically, iOS or iPadOS updates that have two decimal points are bug-fix updates, and releases that bring new features have just one decimal point.

The mobile device update fixes a problem that prevented storage for being cleared as intended, addressed a bug that could cause "some displays to exhibit a green tint," and fixed an issue "where Exposure Notifications could be disabled for some users." As for macOS, just two changes are named by Apple: a fix for a "stability issue" related to virtualization apps, and a wake-from-sleep problem unique to the brand-new iMac that just released.
