Hello ! For information, links from the 1st page have been restored, thank's Unfortunately, I have a problem I can't seem to launch installation Up here, OSX 10.6.3 was installed on my XPS and everything worked perfectly. I want to try OSX 10.8.3 or 10.9.4 or 10.10.5 (all official), I can no longer start the installation after the first phase of boot, I get a black screen when the menus of install should appear. I tried to do my installation key with bcc's method (first page), with MyHack and with #####, with the generic Extra folder and those of bcc's (FakeSMC and VoodooPS2 in Extra / Extensions and org.chameleon.boot and smbios in Extra) and nothing works ... My key is formatted as necessary and makes 32Gb (1 partition, MacOS extented, MBR), in the Bios A15, IntelSpeedStep, Virtualization and DynamicAcceleration are disabled, SATA in AHCI mode, LAN, BT, Wifi, USB enabled. I also tested with "-x" and "-x PCIRootUID=1" "-x GraphicsEnabler=Yes", nothing changes ... If you ever have an idea, let me know!
