Colin Fausnaught posted a question in OS X Mavericks 10.9I'm trying to install Maverick as a VM through virtualbox, but I keep getting held up at this error. I'm using the Niresh iso. Here are my specs Intel® Coreâ„¢ i7-4810MQ Mobile Processor 2.80 GHz 6M Smart Cache, Max Turbo Freq. 3.80 GHz 1 TB Seagate Solid State Hybrid 64MB Cache SATA III 6.0 GB/s Hard Drive 12GB (4GBx3) DDR3-1600 SODIMM Memory (G.SKILL) Mobile Intel HM87 Express Chipset Mainboard NVIDIA GTX 860M 2GB PCIe Video (NB-396-101) Intel® Centrino® Ultimate-N 6300 a/b/g/n WiFi Card [intel WiDi Ready] And here is a pic of the issue tried a few flags like -x and PCIRootUID=0/1, doesn't seem to be working for me! This is a laptop build too by the way.
