Help, system uptime error doesn't let Yosemite boot

[paulklaff]

Hi all,

I'm reinstalling Yosemite on a new SSD (Crucial BX300) and after a successful installation with Unibeast (and resolved the boot0 error), either the computer reboots automatically after showing this message when booting with the USB stick, or gets stuck when trying to boot with the SSD.

I know it happened to other people but it seems to be a specific problem to each one. Any ideas? Is it the IntelCPUPowerManagement? How can I reinstall kexts if the computer reboots after one minute?

It has been 5 days I'm trying to reinstall this OS, I'm exhausted...! Thank you.

Is it the IntelCPUPowerManagement?

Yes, kernel panic caused by AppleIntelCPUPowerManagement.kext
Install NullCPUPowerManagement.kext

Done, thank you. Now it boots but stops half the way, when booting in safe mode, this appears :

Probably the kexts again...

Even when booting with the USB now it doesn't work anymore, while it worked well the first times.
This is with verbose mode : stuck there and after a while I got an "empty set" logo.
