Mac Os X version: 10.11.6
Since a few months, the Mac App Store application keeps telling me there is an update available for my system. Some application called "CodeBox" (website). If I try to perform the update, it tells me it is linked to another account and thus cannot perform it. But I can't remove it neither, as it is nowhere to be found on my machine!
I tried to find it via a full text search:
grep "CodeBox" -R -l / but it only showed a few irrelevant files.
-softwareupdate -l` (returns "no new software available).
Note that this is a legit version of Mac Os X (some forums threads say it could come from a cracked version of Mac Os X found on torrent sites).
I'm at loss here. Any idea?
