Ladies and gentlemen this is a first. Apple has released macOS Catalina 10.15.7 update to fix more issues.
- Resolves an issue where macOS would not automatically connect to Wi-Fi networks
- Fixes an issue that could prevent files syncing through iCloud Drive
- Addresses a graphic issue that may occur on iMac (Retina 5K, 27-inch, 2020) with Radeon Pro 5700 XT
I have never seen a modern macOS version go to version 7. If you plan to use Catalina for a while and not update to macOS Big Sur right a way, then it would be a good idea to download and install the Combo Updater. I have installed it, everything seems OK.
