Cylance & macOS


This issue has been resolved.


Cylance is releasing a hotfix to the macOS Agent version 1494 to provide a workaround to keep macOS Mojave endpoints from deadlocking. This workaround disables the Memory Protection and Script Control features on the Agent when macOS Mojave is identified as the operating system running on the endpoint. The Memory Protection and Script Control policy settings will remain intact.

All macOS versions High Sierra (10.13), and lower, will continue to be fully supported by CylancePROTECT, including Memory Protection and Script Control.

The hotfix is being released September 20th, 2018.


Cylance recommends not upgrading to macOS Mojave until the CylancePROTECT Agent 1500 release in late October 2018.

Nobody should attempt to upgrade to Mojave until we verify that the new Agent has been installed.
