Short step-by-step manual. It's also suitable, if you have no any Windows machine near. Please note, that this is guide for users, which already has experience in Windows activation: - Download and install VMware Fusion - Copy /Applications/VMware Fusion.app/Contents/Library/vmware-vmx to somewhere. I recommend to ~/Downloads. ("~" means your home directory) - Open terminal window and run: $ segedit vmware-vmx -extract __VMWARE bios440 bios440.rom (Personally, I don't like embedded terminal program and using iTem2) This will extract BIOS rom file from vmware-vmx and save it as bios440.rom, on which we will apply a SLIC patch. - Now, you need any Windows machine. You can also install virtual Windows machine, using your VMware Fusion - Install latest "Andy's Phoenix BIOS tool" (sorry, can't post URL, use "Forum search") - Install latest "RW-Everything" to get AcpiTbls.rw (The same thing, use "Forum search") - After You'll get patched bios440.rom from Windows machine, put it somewhere on your Mac. I recommend to ~/Documents (If you using virtual Windows machine, then I recommend to use "shared folder" for quick file exchange - Virtual Machine - Sharing - Sharing Settigs) - Now, You can create and install virtual Windows machine, if you haven't did it before. - After installation, You should shutdown your Windows virtual machine - Locate .vmx file of you Windows virtual machine. Usually it's in ~/Documents/... - Open .vmx file and put in the end: bios440.filename = "/path/to/your/patched/bios440.rom/file" (example: bios440.filename = "/Users/acid/Documents/bios440.rom") - Now, your virtual machine has correct BIOS for activation - Run your virtual machine and make usual procedure for certificate (.xrm-ms) installation and activation. Good luck!
