Hi brothers

 

once i installed iPc 10.5.6 , restarted to complete installation but because of advice from expert i booted with ( cpus=1 ) , after apple logo appeared then the bluse background then i got black screen and the mouse pointer is located on the top left corner , the loading ball appear and disappear freq.

 

 

i tried to boot with cpus=2 and -v -f and the same proplem

when i booted with -x ( safe boot ) it worked fine

 

i tried using osx86 tools to repair permissions or chear cache but nothing happened

 

Any suggesstions are welcomed
