Do I need the legacy system on my Late 2015 iMac running Monterey?
Do I need the Legacy System on my 2015 iMac running Monterey?
Question marked as
If you are getting an alert about a Legacy System Extension, it's just a warning that the extension is probably an old 32-bit component of the OS and will be incompatible with the current or future macOS versions.
Have you recently upgraded from a previous OS to Monterey?
The extension was likely required for some piece of software that was installed prior to macOS Catalina and anything newer. 32-bit apps and components no longer work in the newest OS versions.
They unneeded and don't work.
