Not Planned

Hi ,
I've checked with our development and support team and you can't install MDR on its own on a macOS platform (unlike on Windows).
It’ll be installed alongside any other product you install via the command line.

Hope that helps,
Rémi
 

Missing MDR product on MacOS command line options

You’re missing the option to install MDR in the command line install for MacOS. You’ve included AV, intercept, and encryption, but you are missing MDR.
