Microsoft’s advice about Office for Mac 2011 wasn’t unexpected, since support for the application suite is slated to end 10 October, a date Microsoft first stamped on the calendar two years ago, but has not widely publicised since. (Version 15.35 was released in June since then, Microsoft has issued 15.36 in July and 15.37 in August.) “In some cases, you may not be able to launch the Office apps ,” Microsoft said.Īpple is expected to release High Sierra to customers in September. In the same document, Microsoft told those running the newer Office 2016 for Mac that they must update its applications to version 15.35 or later, if they intend to upgrade their Macs to High Sierra.

Software vendors have quickly followed suit and no longer support products on High Sierra which includes Microsoft Office 365 and Adobe CC 2021. Apple fixed the vulnerability in Big Sur 11.2.1, Catalina 10.15.7 and Mojave 10.14.6, but did not fix High Sierra and dropped support for that version.

In early February, a severe security flaw was discovered in macOS. Not only that, but the campus recommended antivirus for Macs is no longer supported on High Sierra which means Macs that are running this older operating system are no longer protected from viruses and other malicious attacks. If you’re running macOS High Sierra 10.13 or earlier versions of macOS, you should upgrade to a newer version of macOS immediately as High Sierra and older versions are no longer supported by Apple.
