      Hello folks! As some things are being fixed, we'll keep you updated. Per hour the Forum Rules don't have a dedicated "Tab", so here is the place that we have our Rules back. New Users Lounge > [READ] - InsanelyMac Forum Rules - The InsanelyMac Staff Team. 

Instant Reboot - Core i5 540M Laptop

My computer shuts off as soon as Chameleon is done loading all files and kernel.


I don't have time to take any picture, because it just instantly reboots.


I've tried many things:

PCIRootUID=1, cpus=1, maxmem=2048, busratio=19 and many more


If anyone could help, it would be highly appreciated!

Security > Memory Protection > Execution Prevention [Enabled] in ThinkPad Setup
