Jamf removed the ability to mass action modify the management status for computers in 10.49.

Modifying the management status of computers in Jamf Pro can still be useful for various asset management reasons. Expanding on the sentiment of Der Flounder, I created a simple Python tool to set the management status of Jamf Pro computer object(s) via the universal api. Rather than using a pre-defined static list - the tool uses an Advanced Computer Search to iterate over.

Here’s an example of sms-cli modifying the management status of 3 computers.

$ python ./sms-cli.py --url=https://company.jamfcloud.com --username=user --managed --id=156 --password='pass'
Are you sure you want to change the management status for the device(s)? [y/N]: y
[SMS-CLI] Using search ID: Computers - Test Group
