rimbalza

Hi, I'm in the same situation, posted here https://forum.devolutions.net/topics/52144/not-able-to-connect-via-rdp-to-windows-server-2022-from-rdm-installed- about the problem, but that thread is for windows, my bad.

Posting here to stay updated. I also rolled back one version to 3.9 and the problem is gone.

Same problem here with 2025.3.10.2 for Mac. Unable to connect to the RDP hosts I always connect to.

Security nego connect failed 0x002000c.

Edit: rolled back to 2025.3.9.2 and it works again.

Same here running 2025.3.8.5 on MacOS 15.7.1 on Intel i9.

Fans start spinning as soos as I run RDM, even with no sessions (local DB).

I have a 3rd party USB charger and when using RDM it discharges faster than it can charge.

Being Idle it takes 200% cpu (from htop), that means two cores running at full speed while doing nothing.

MacOS says it is hogging the laptop:

Unable to use it any more.
