X-TraxxX Posted November 17, 2008 Share Posted November 17, 2008 Hello Fellow Members I'm new in the Mac community. I do have knowledge of linux but I'm no expert. Hopefully this will help me in some way with my first experience with leopard. The Situation: After the installation procedure of Leopard 10.5.5, the point at which your computer first restarts after the installation reaches 100%. My computer boots to the Darwin Screen then goes into an endless reboot cycle. Distro: iDeneb_v1.3_10.5.5_ISO System Specs: Processor: Intel Core 2 Quad Q9550 2.83Mhz 12MB L2 cache SSE3 + SSE4.1 Support. Motherboard: ASROCK P43Twins1600 (Intel P43 Northbridge, Intel ICH10 Southbridge, Audio: ALC888, Lan: Realtek RTL8111B/C ) Bios version 1.80 Graphics Card: Asus Nvidia Geforce EN9500GT 512MBDDR3 Memory: 2x OCZ 2GB Dual Channel DDR2 PC2-8500 1066Mhz Harddrive: Western Digital Caviar Black 500GB SATAII Interaction: I have tried entering -v -s variables at the darwin boot screen and I still experience the endless reboot situation. :censored2: Any help would be greatly appreciated!!

X-TraxxX Posted November 18, 2008 Author Share Posted November 18, 2008 I thought a reinstall would help but it did nothing. I have the same issue. any idea's?

brgroup Posted November 18, 2008 Share Posted November 18, 2008 What kernel did you install? Also, did you happen to install too many kexts in customization? It may take a long time, but you'll need to troubleshoot your install, changing one or two settings at a time to narrow down the problem.. Also you may try an older kernel install disk..iAtkos 10.5.4 or even Leo4All/Kalyway 10.5.2 and see if you can at least get in installed, then step delta-upgrade into a 10.5.5 version..

X-TraxxX Posted November 18, 2008 Author Share Posted November 18, 2008 I would believe that working with an older version may be the best bet. I haven't checked what kernel was installed but I will.

mollypepperpot Posted December 21, 2008 Share Posted December 21, 2008 Hi I had the same problem when I updated to 10.5.4 kalyway - you need to do the following: Type in the following command in terminal mode: sudo vi /library/preferences/systemconfiguration/com.apple.boot.plist [then press enter and type in your password when prompted] [press i and type cpus=1 between the string tags] eg <key>kernel flags</key> <string>cpus=1</string> [press escape key] [then type the following] :wq [close out of terminal and reboot] this should fix the issue, if you haven't figured it out already!

lipps Posted December 22, 2008 Share Posted December 22, 2008 I am having the same problem, my question is, how do you get to terminal mode if the computer won't boot up? I get about 3 or 4 line in to boot up and it reboots !!Do I need to boot it with the dvd in the drive? I am using the ideneb also.
