Hi all. I'm on the verge of giving up when it comes to installing Mavericks on my main desktop (Inspiron 660 with a core i5 3340 and either a 750 Ti or an 8400 GS 1 GB or a GT 730 4 GB. None of the GPU's work with Mavericks aside from the 8400 since I had used the bootflags "-v dart=0 GraphicsEnabler=Yes nvda_drv=1" and that gave me full resolution at the installer and I installed and rebooted, only to be greeted with the error "IOBluetoothHCIController -- Missing Bluetooth Controller Transport!". I have tried countless boot flag combinations to try and fix this, yet it consistently is giving me this error. The reason I want to use Mavericks is I love the interface it has compared to the flat iOS design which the others after it have. If anyone could give me any pointers, I'd be grateful.. Oh, and if it helps: booting into safe mode doesn't work either. It simply reboots after getting past the IOBluetooth error.
