[spugliese82]

Good day at all,

I have a problem with my macbook, since last day that I had install on my macbook the program Glowworm my macbook didn't start up anymore.

I made a reset wit command keys, but nothing is changed except that now start, that load the apple logo seem that is loading the OS and that the screen become black and automatically it restart againg and repeat the same operation always

I can do something for restore my macbook by my-self?
Thanks in advance.
