[QUOTE="awirz, post: 805478, member: 87547"] Hi lady :) this problem is very well known to me! One of my customers had it after installing a Security Update (SecUpd2008-006). And I had another variation of it on 2 of my Macs (startup OK but working was deadly slow with intermediate crashes). So I am now VERY reluctant to install Security Updates since they can wreck your system in minutes. Try this: start up your Mac with Cmd-S pressed until you see lines being written to the screen. You are in Single User Mode now. Then do the following (type text within double quotes ONLY and take care to type the spaces): 1. "/sbin/fsck -fy" 2. "/sbin/mount -uw /" 3. "sh /etc/rc" step 1 checks the harddisk, step 2 mounts it and step 3 attempts to continue the system startup until the Login dialog appears. A lot of lines will print on the screen, most of them informational but some of them maybe created by fatal errors. Any errors in conjunction with the loginwindow process are crucial! Let me know what you see. If loginwindow does not start properly (you get no GUI to login), you have to shutdown the system manually using the command "/sbin/shutdown -h now". If you don't see the cursor or the prompt, press return before entering the above command. Good luck Adrian [/QUOTE]
