Where the in the world are you working where MDM is the limiting factor on Linux deployments? North Korea?

Macs are a minority in the datacenter even compared to Windows server. The concept of a datacenter Mac would disappear completely if Apple let free OSes sign macOS/iOS apps.

I’m talking about using MDM with Mac OS (to take advantage of Apple Silicon, not licensing) in contrast to the tools we already have with other OSes. Probably you could do it to achieve a large scale on prem Linux deployment, fortunately I’ve never tried.
