Does software update error 41 mean the download is already there?

Is software update error 41 the equivalent of a theoretical “DownloadAlreadyPresent” UpdateResults item?

When MDM sends ScheduleOSUpdate w/ DownloadOnly to a device that had previously downloaded the update by itself (device has automatic update downloads enabled), it returns:

The operation couldn't be completed. (com.apple.softwareupdateservices.errors error 41

Should MDM treat that as a success and move on to InstallASAP?

Yes, error code 41 does mean that an update has already been downloaded.

You should confirm the status of the download by sending the OSUpdateStatus command. An IsDownloaded=true key in the response is a sure sign the device is ready for an InstallASAP command.
