Mac running slow, Keychain keeps telling me Google Desktop has changed and asks for authentication. Do I have a virus, or is something wrong with keychain?
Activity Monitor tells me that
securityd is using 1.5GB of memory; something is wrong.
Googling suggests that
/var/db/CodeEquivalenceDatabase may be corrupted. Furthermore, it seems that it can rebuild itself, so the lizard's tail treatment is suggested: remove the offending part.
I did the following:
sudo rm -rf CodeEquivalenceDatabase
sudo rm -rf is serious magic, and can get you in serious trouble; be careful (long ago, I once did
cd /dev ; rm -rf mouse * — where I meant
mouse* — don't try this at home) ... the faint-of-heart could take a copy of the file instead and remove it later:
mv CodeEquivalenceDatabase CodeEquivalenceDatabase.old
In any case, this seemed to work. After a restart keychain asks me to authenticate access for various apps:
Mail, ... I do this. Everything seems normal, and
securityd is using "only" 28MB of memory (back in the old days, we used to run serious theorem provers in less).
