Add a new certificate in unify controller

I’m making use of Ubiquiti AP’s and therefore use the Unify software to manage them. I have it installed within an “ordinary” vm.
The software normally uses a self-signed certificate. This is not a big issue as it is my local network.

Using Rosette with UTM and Docker

When buying a new laptop I settled for a MacBook Pro with a M2 processor. As I was used to an Intel based MacBook Pro with virtual machines and Docker containers I keep searching for replacements for the functionality I was used to.
