+6Hello Jamf Nation, I have been attempting to deploy the latest macOS 15.6 update to the pending devices. However, each time I use the Software Updates feature to update the version, I encounter the following error: “UnableToFindUpdatesAndOutOfRetries”. As a result, the devices do not receive the update.
Do you have any suggestions or alternative methods I can try?

Download the Mac Envaluation Utility from Apple Seed fo IT, and run it on the devices. If you dont have access to Apple Seed, you can look in to Jamf Enviornment Test (JET) but it has not been updated in awhile. My gut is saying some host needed for managed updates to function is not open or getting a TLS inspection and the traffic is failing.
The JET application was discontinued, now you can use JamfCheck (https://github.com/txhaflaire/JamfCheck) basically you have some URL blocked, you can check in the following link (https://support.apple.com/en-us/101555) the links that are necessary to update the macOS, check if they are blocked in your organization

Thank you, I'll try that workaround, and I'll let you know how it goes.

recommendedUpdates=$(defaults read /Library/Preferences/com.apple.SoftwareUpdate.plist RecommendedUpdates | wc -l | awk '{print $1}')
if [[ recommendedUpdates -gt 2 ]]; then
echo "<result>True</result>"
else
echo "<result>False</result>"
fiTry running this EA to check if the device has any pending software updates. If it shows False but the device is not on the latest version, there may be network issues preventing the update. You can also download the Mac Evaluation utility and run it to identify any blocks and resolve them.
