Here at the college we have both Mac and Windows systems. The Mac in my office won't ever boot for me on the first try. It always locks up just before the Dock should appear and has to be re-booted via the front panel power switch. Second try always works. Any suggestions?
whatever is causing the problem is kicking in at the tail end of logging in the user session; at that point the OS has booted and the user session may be launching any "login items", so there are a few things you can try, in order of increasing complexity
1. restart holding the shift key; this turns a lot of optional stuff off; if the system reboots correctly, then you know it is either your account preferences or something that is launching automatically at startup, so step 2 is the first thing to try; if this restart still hangs, go to step 3 instead
2. review your login items; go to System Preferences > Accounts and click on the Login Items tab (it's a little different on older versions of the OS); review this list -- if you see anything that you recognize as unneeded, select it and click the minus buton and delete it; try restarting to see if that was the cure; if not, maybe there is still something in Login Items that is causing the hang; you may need one of these tools, so the real if you take it out of login items and that cures the problem, you may need to delete the preferences or reinstall that tool; describing how is beyond the scope of this help, so use your judgment
3. if still stuck, create a new user account: go to System Preferences > Accounts, click the lock and enter your password, and click the "+" below the account list; after you create a new account, choose Log Out from the Apple menu, then log into the new account -- if the problem has gone away, you can be sure it is somewhere in your regular account's preferences; probably the easiest thing to do is eliminate all Login items, or use the new account and start fresh (it may need new preferences for every application, including email, etc.)
