bgiparser (backgrounditems.btm/BackgroundItems-v*.btm parser)

The entries of "Login Items" are stored in "~/Library/Application Support/com.apple.backgroundtaskmanagementagent/backgrounditems.btm" since macOS 10.13 High Sierra. This tool can parse it and output pairs of entry name and application path as JSON data.

Apple has changed the location of the file that records Login Items in macOS 13 Ventura and the format has also been changed. This script supports the new format too. New file location is "/private/var/db/com.apple.backgroundtaskmanagement/BackgroundItems-v*.btm".

By the way, you can also download another parsing tool from here. Or just run sfltool dumpbtm on macOS 13.

Limitation

BackgroundItems-v*.btm only has user UUIDs, not user IDs or usernames. You can get the UUID corresponding to a username on localhost with the following command. In other words, if you parse BackgroundItems-v*.btm obtained from other host, you cannot reliably identify the username.

% sudo dscl . read /Users/root generateduid
dsAttrTypeNative:generateduid: FFFFEEEE-DDDD-CCCC-BBBB-AAAA00000000

TODO

  • Confirm condition of each entry (enable or disable)
  • Support macOS 13
