I had perfectly working hackintosh on 10.9. When I updated to 10.9.3, it wouldn't boot and got stuck after IO Bluetooh completed. So I removed all the graphic related kexts.
I also tried installing kexts from http://www.osx86.net/file/4015-nvda4all-nvidia-webdrivers-easy-installer-machack-all-smbios-supported-3340101f01-for-1093-mavericks/ but now its getting stuck at AGPM controller unknown platform
Any help appreciated.
I have Dell XPS L501x laptop
