apple_hacker Posted July 17, 2010 Share Posted July 17, 2010 After installing Mac OS X 10.5.8 (iDeneb) on my machine (spec below) everything worked just fine except I often used to get sytem restart while booting, after the chameleon loader screen. I saw in this forum and modified the boot.plist by adding cpus=1 flag in it. Now everything works fine and I don't get those restarts again but now Mac os x takes longer time to boot than it was before. Is it due to the cpus=1 flag I added ??? What exactly does this cpus=1 means ???? System Spec. GA-G31M-ES2L(Mobo) Intel PentiumD 820 (CPU) 2GB 667MHz DDR2 (Transcend) Seagate Baracuda 250GB SATA RTL 8139C PCI Ethernet Card Link to comment https://www.insanelymac.com/forum/topic/225472-slow-boot-after-using-cpus1-flag/ Share on other sites More sharing options...
