The option of not updating to future macOS version remains, but it may be better to look at alternative apps rather than going that route, particularly if you want to take advantage of new features available in upcoming macOS releases. If the app that the message mentions is no longer in development, things get trickier. If the app has been updated by the developer, often simply installing that available update will resolve the issue by removing the dependency on the kernel extension.īeyond that, there isn’t much you can do at this point other than making sure the developer of the flagged app knows that you need a solution to be in place by the end of this year for macOS Big Sur and alter.Īnother option is that you could decide not to update to macOS Monterey 12 / Big Sur 11 / 10.16 once it becomes available, but that has its own security implications since newer versions of Mac system software tend to be the most secure.

What Are Legacy System Extensions on Mac? So, what exactly does this message mean? Not a lot right now, but come the arrival of macOS Monterey 12, macOS Big Sur 11, / 10.16, and from the end of 2020 onward – it’s going to mean a lot. ![]() Titled “Legacy System Extension”, the message goes on to note that “ existing software on your system loaded a legacy system extension by (developer) which will be incompatible with a future version of macOS” and while that might not mean much to most people, it is something you should take note of.
