- Joe's positive LSD story:
A Possitive LSD Story on The News - Bill Hicks on Drugs.

iMac 27-inch Retina 5K initially failed to log into user, finally logged into user but app icons were generic, apps wouldn't open, system very slow; after deleting user account, preserving home folder, and then recreating user account and reclaiming home folder, the user account would log in and work properly but system wouldn't restart or shut down, getting stuck on black screen with arrow cursor; system log showed repeating messages about com.apple.lsd process crashing; tried safe boot and re-installing 10.11.6 with no luck; tried rebuilding LaunchServices using the following command with no change:

/System/Library/Frameworks/CoreServices.framework/Versions/A/Frameworks/LaunchServices.framework/Versions/A/Support/lsregister -kill -seed -r

Thanks to Apple discussion forums, Joe learned a command to list the open files associated with a given process:
pgrep -u `id -u` lsd | xargs slof -p
which listed a file in /private/var/folders/kv/2kk40mdv5wdccq6hb7y3rgk80000gn/0/com.apple.LaunchServices-134501.csstore

Deleting that file didn't work, but after researching whether it was OK to delete folders in /private/var/folders/, Joe deleted everything inside /private/var/folders/ and restarted. Sure enough, the system restarted successfully and has worked properly ever since.
