talkingmoose / Download device model information from Jamf.zsh
Last active June 19, 2024 15:47
Apple doesn't provide a 1:1 list of devices for iOS, iPadOS, tvOS, watchOS, and visionOS. However, Jamf does maintain a public list for its Jamf Pro servers. This script downloads the listm parses the information, and creates a record of each device followed by its display name.
#!/bin/zsh
# set -x # show command
# trap read debug # require a RETURN after each command
# download mobile device data from Jamf
