Google points to a lack of Apple support coverage
As a reason for the step, Google points out that the operating systems are long outside of Apple’s support window. However, it is “essential to ensure security” to run the browser on a supported operating system, according to the developer.
However, macOS 10.13 High Sierra and 10.14 Mojave – which still run Chrome 104 – have long stopped receiving security updates from Apple. macOS 10.15 Catalina is also likely to drop out of coverage soon. There is no clear update promise for Apple’s operating systems. Apple is only continuing to develop its own Safari browser for the operating systems that are still supported, and from autumn macOS 11 Big Sur will be the new minimum requirement.
Owners of old Macs currently have the option of switching to another major browser such as Firefox or Microsoft Edge, both of which will continue to receive updates but require at least macOS 10.12 – but are no longer intended for OS X 10.11. All Macs that support macOS 10.12 can also be updated to macOS 10.13.
macOS 10.12 and older before the software end
Support for macOS versions prior to 10.13 High Sierra will soon shrink significantly anyway: With Apple’s development environment Xcode 14, which is scheduled for autumn, developers can no longer create software for OS X 10.9 Mavericks, OS X 10.10 Yosemite, OS X 10.11 El Capitan and macOS 10.12 Sierra write.
