Mavericks isn't booting up

Recommended Posts



sorry for the title. Don't know how to describe it any better.


My PC Build:

- Gigabyte 970A - DS3

- AMD Phenom II BE 955

- R9 270X





After trying to install Yosemite and failing I thought maybe Mavericks will work. 

The installation worked fine. The problems began at first time booting up after installation. I got Blackscreen and the system won't start. I did as in the guide advised:


 If You're Stuck at DSMOS Has Arrived

Reboot Using "-s" Kernel Flag (Without The Quotes)

type "fsck -fy" press enter (Without The Quotes)

type "mount -uw /" press enter (Without The Quotes)

type "grafix backup all" press enter (Without The Quotes)

type "reboot" press enter (Without The Quotes)

After that fix and bootflag -x my OS X booted up. Problem now is its slow, I think my Graphics don't work as intended.  My network is working, which is nice.

I downloaded the r9 270x driver https://www.maconpc.com/files/file/208-amd-radeon-r9-270-270x-series/and installed it. 

Installation was successful but it still only boots up with bootflag -x. The graphics are still laggy and all, so my guess is that the driver/the graphic card still don't work as they should.

The resolution changed and if I don't do any action it looks quite nice.


Do you guys have any suggestions? Is my PC-build just not compatible to get a Hackintosh running?



EDIT: OSX is now booting up without -x and without any bootflags at all... BUT Graphics are still laggy, seems like the AMD R9 270X is not working with OSX.

@Eloquenz I understand this is a really late reply (sorry, I went offline for a while) - but I just took another look at your post.

It looks like your driver isn't working as you're having too boot into safe mode (-x), so that's why it's laggy as safe mode probably isn't running that driver.
