If you are using Logitech Options or Logitech Control Center (LCC) on macOS you may see a message that legacy system extensions signed by Logitech Inc. will be incompatible with future versions of macOS and recommending to contact the developer for support. Apple provides more information about this message here: About legacy system extensions.

Logitech is aware of this and we are working on updating Options and LCC software to ensure we comply with Apple’s guidelines and also to help Apple improve its security and reliability.

The Legacy System Extension message will be displayed the first time Logitech Options or LCC loads and again periodically while they remain installed and in use, and until we have released new versions of Options and LCC. We do not yet have a release date, but you can check for the latest downloads here.

NOTE: Logitech Options and LCC will continue to work as normal after you click OK.
