ameris_cyning Posted February 28, 2013 Share Posted February 28, 2013 there are only 2 USB ports in left of my laptop Found your problem. Laptops require further tweaking. These are IOUSBFamily.kext and IOUSBMassStorageClass.kext 10.8 rollback kexts Download and use kext wizard (or any other kext installers) with these kexts.

sqishy Posted June 30, 2013 Share Posted June 30, 2013 The XPS 15z has 3 USB ports the 2 front ones are USB3 and the back one is eSATA/USB2 you can still use this but it does feel a bit tighter Link to comment https://www.insanelymac.com/forum/topic/286697-mouse-not-working-and-must-boot-in-safe-boot/#findComment-1929060 Share on other sites More sharing options...
