Thread: Low jack difficulty by Mac

I tried to install low jack on PC, and in fact it won't start now. I have the 1nd version of MacBook Pro from summer 2007, running OS 10.6 snow leopard. The grey monitor arises, and apple, and gear progress thing, and it just keeps spinning. I called low jack support, and the program was registered, but never installed, so there is no method that program is locking the PC as if I wrap it. I don’t believe for few reasons the program was installed correct, so I tried to restart it, and it won't start now. Any suggestions

Sounds more similar to corrupt file system as PC isn't yet starting quite than low jack or any other software you prefer
OR
Get a new Mac OS X 10.6 DVD, and reinstall the Mac OS it will work well with it.
