This Mac flaw lets hackers hijack your machine — update your old OS now | #firefox | #firefoxsecurity


Until recently, Apple’s TextEdit program, which comes built into macOS as the default text and document editor, had a very serious bug. It could have revealed your IP address and the contents of directories, and in conjunction with other exploits could even be used to run JavaScript to completely take over your Mac. 

The good news is that the flaw was patched by Apple with the release of macOS 10.15 Catalina in October 2019, but it does serve as an important reminder to update any Macs you have that are running older versions of MacOS.
