Environment
- CB Defense PSC Sensor: 3.2.x.x and higher
- Apple macOS: 10.14.5
Question
Why do Macs running macOS 10.14.5 issue a System Extension Warning after a successful install of the Sensor?
Example:
System Extension Warning
One or more system extensions that you have approved will be incompatible with a future version of
macOS. Please contact "Carbon Black, Inc." for support.
Answer
This references the fact that Apple will be deprecating the Kernel Extension (KEXT) in favor of a System Extension framework
Additional Notes
- This issue does not affect current Sensor compatibility with macOS 10.14.x
- Apple has not yet defined when KEXTs will be deprecated; the System Extension framework will be introduced with macOS 10.15 (Catalina)
- The initial release of macOS 10.15 (Catalina) will still allow KEXTs
- Carbon Black is planning for this occurrence as noted here
