Standalone updaters are now available as follows: Once the installation is complete, you should be able to download and install an update to bring back up to 1.66, which is the same version prior to this update. Oddly, this update installs an old version of Apple’s Malware Removal Tool, MRT, 1.62. There are no new firmware updates provided. The most serious of them, which affects all three versions of macOS, is a sandbox vulnerability which gives access to restricted files (CVE-2020-9968). There are only four in total, of which two apply to Catalina. Security fixes are detailed for all three here. The initial release of Mojave Security Update 2020-005 has caused widespread problems: for the moment, it seems wise not to install it. This is accompanied by Security Updates for High Sierra and Mojave. Apple has just released a surprise update to macOS 10.15 Catalina, bringing it to version 10.15.7.Īt around 2.6 GB, it’s relatively small, and fixes a number of important issues, including problems connecting automatically to Wi-Fi networks, failure to sync files through iCloud Drive, and problems with Radeon Pro 5700 XT graphics support on the latest iMac Retina 5K, 27-inch, 2020.
