This release has support for fixing permissions on the two main suspects for kext installation (/S/L/E and /L/E) and for rebuilding kextcache.
Right now, the script simply runs through all three options (/S/L/E, then to /L/E, then kextcache). It also has root user detection (If User ID is 0, proceed. If not, print the message and exit), so the script will print a message asking for root before it exits instead of just failing.
