Difference between Normal Boot and Safe Boot
I have a MacBook Early 2008 with Lion 10.7.3, this machine ran perfectly with Snow Leopard, did not have any kind of problem.
Since i installed Lion the problems started, begin with WiFi drop problem that i solved installed SL driver (IO80211Family.kext), and the MacBook Freeze sometimes after start up, looking for a solution when i start in Safe Boot Mode (Shift key + Command + v) computer run perfectly, i have standar software with last versions (Office 2011, Vmware and Adobe Photoshop Elements 9) with a HP and Dell Printers. What is the difference between Normal and Safe Boot in order to try to find the source of problem?
Thanks in advance
