Unable to install Remote Management Profile – macOS Big Sur 11.0.1

rbdk97 · November 20, 2020, 12:51am

Hello! Long-time user of Prey here.

I am unable to install the Remote Management Profile (prey.mobileconfig).

In the Profiles pane in System Preferences, I get the following message when I click “install” for the Profile:

Profile installation failed.
MDM payload is missing “ServerCapabilities” key that indicates it supports a user channel.

The error code shown in Console for the process mdmclient is: -106

Configuration details:

Device: 2018 MacBook Pro 15"
OS: macOS Big Sur 11.0.1
Prey version: v1.9.6

Is there a known way to resolve this? I’ve uploaded a screenshot of the error message. Thanks in advance!

I’m getting the same issue on MacBook Pro (Retina, 15-inch, Mid 2015), same macOS/Prey versions. The only remote profile I can download via Prey (using the one automatically selected) seems to be for iOS rather than macOS - is this the problem? I’ve added a screen shot

Same here — the only Profile that Prey is letting me download has “iOS Mobile Services” in the description.

Not sure that actually is a problem, though… I have an older MacBook Pro (Retina, 15-inch, Mid-2012, running Mojave) which also has Prey installed (and it’s been working fine for a long time). That machine has a Remote Management Profile downloaded from Prey (done a few months ago), and it also says “iOS Mobile Services” in the description.

I’m beginning to think the issues you and I are having are specific to Big Sur… Again, not sure, though.

I see this is an old topic, but I can’t install the certificate for MacOS devices. I’m getting a similar problem as people with the iOS, except mine is unverified (see screenshot).

Just to be clear, I’m on a MacBook Pro (Big Sur), so I’m not sure the iOS certificate is the correct one. However, it’s the only option on my Prey control panel!

Any suggestions?

Update: I know that installing this certificate only gives us a few extra options, so is it that important? And, maybe since I’m running the free version I just don’t get the same certificate?
