Hi Jake Lo, that's it..... Thank You. So i look if all will function. But this will take a little time. Best Regards jolly roger

Hello Hervé, tried your guide but got also problems with CPU. See picture. Best Regards jolly roger

I've tried this guide here....... https://osxlatitude.com/index.php?/topic/6192-guide-mavericks-on-dell-latitude-e6420/ My Mavericks OSX and the Yosemite OSX are downloaded from the App Store with my account. Best Regards jolly roger

Hello, ok. here is the picture with the CPU failure code. Best Regards jolly roger

Hello, i tried to make a bootable stick with Mavericks and got CPU failures and i tried to make a bootable Yosemite stick with this guide and the guide linked there but it doen't work too. There will be no bootloder found or no bootable system found on the stick........ Am i too stupid for that Hackintosh thing or my Dell 6420 is not willing to be a Hackintosh...... I spend too much hours for that and no success....... Best Regards jolly roger

Hello, tried an other Extra-Pack, but doesn't work. There is always the CPU error. I want to attach a screenshot, but it will not work. P-State stepper error 18 at step 35 in context 2 on CPU 0 Backtrace (CPU 2) Frame: Return Adress. 0xffffff0102dd3ce0 : 0xfffff8000222f79 ........... Best Regards jolly roger

Hello, i think so....... But the CPU failures.......? Could this be a driver (kext) problem or is there something wrong with the Laptop? Windows 7 worked without problems. Best Regards jolly roger

I formated it as Apple Mac OS Extended Journaled with MBR. I boot up with -v and got some CPU failures while booting. Best Regards jolly roger

doesn't work.

Hello Herve, will try this. Thanks. After making the Mavericks system on the stick i take the e6420 drivers as described in the first post, right? @ Jake Lo I have reseted the Bios to Default Settings and make the extra choice of the AHCI setting. Best Regards jolly roger
