com.apple.launchd: com.apple.launchd.peruser error

Per-user launchd job overrides (e.g. which per-user jobs are disabled for a user) are located in subdirectories of /private/var/db/launchd.db/, e.g. com.apple.launchd.peruser.501.

Open Terminal and see who owns this directory:

ls -ld /private/var/db/launchd.db/com.apple.launchd.peruser.32697

If the owner (third column) is not a user name, but a numeric ID, that user does not (any longer) exist on your system.

You can just remove that directory and be done with it. If there are special rules in the overrides.plist, it might help you understand the origin of that user and the launchd jobs.

To find out when that launchd per-user directory was created, enter

stat /private/var/db/launchd.db/com.apple.launchd.peruser.32697

It's the last (fourth) date printed.

To find all files on your system not owned by a known user, enter

find / -nouser -ls

If 32697 is not a user on your system (no user name), this might give you some information (e.g. files related to a particular application you installed could mean that application messed with your user settings)
