Problem with Big Sur and M1 MacBook Air

[John McAllister]

I have been using Munkireport-php for 3 years and it has been working fine. Now we have some M1 MacBook Airs and I can not get Munkireport working.

Running Munkireport on a Ubuntu 20.04 VM

Munki 5.2.1 and Munkireport 5.6.4

When I run

sudo /usr/local/munkireport/munkireport-runner

I get the following error.  Also when I look at clients on the web interface the Name of the device is "no name"

  Running security.py
    security.py Error: objc[5087]: Class SPExecutionPolicy is implemented in both /System/Library/PrivateFrameworks/SystemPolicy.framework/Versions/A/SystemPolicy and /usr/sbin/spctl. One of the two will be used. Which one is undefined.

Not sure where to go from here.  Any help would be greatly appreciated.

We have the same issue. 

Running Munkireport on Mac OS Big Sur 11.4. 

Munki is version 5.5.0.4360

Munki Report is version 5.6.3

I was going to wait to upgrade until Munki Report 6 was out of Beta but may try installing 5.6.5 to see if the issue is resolved.
