There should be no such restrictions if you set CsrActiveConfig to 3 or 7 for instance. I guess that setting CsrActiveConfig to 1 only disables kext signing but not FileSystem protection, i.e. Works with Dell Latitude D830 Nvidia QUADRO NVS 135M & Nvidia QUADRO NVS 140M You can use the attached DSDT, it's already patched and works fine whith both Clover and Chameleon. Note that DSDT editing from ECHI to EHC1 is still mandatory in every case. 6 PRT in EHC1 and 4 PRT in EHC2 in OS X 10.11 IOUSBHostFamily.kext vanilla kext. I found out that using a MacBookPro3,1 SMBios eliminates the need of using any extra kext since all ports are already configured for use with D830 hardware : Attached is customized DummyUSBEHCIPCI.kext thanks to the mentioned Guide above and updated DSDT. However, DSDT edits may still be usefull. Thanks to Pokenguyen, stinga111 & VCH888, there's a guide to fix all USB related issues. It could be related to some errors in the proposed DSDT so if you see any, please report ! Fixed ! see below. However on my system, I still have 1 of the 3 ports that isn't working at all (they all works fine on Yosemite). Renaming USBx to UHCx doesn't really matters. Method (_PRW, 0, NotSerialized) // _PRW: Power Resources for WakeĪlso, you must change device (ECHI) to device (EHC1). The patch is quite simple and you'll just need to edit your DSDT and apply PJAlms "Basic Apple Device Renames" available here. UPDATED FOR macOS Sierra 10.12 Developer Preview !įor those who tried to install 10.11 DP1, you may have problem booting your USB stick on your system and actually end up with a "still waiting for root device" error.Īfter some research, I finally managed to successfully boot and install El Capitan on it by patching the DSDT from original bootpack for D830 Nvidia series. If you have a recovery partition, to boot directly into the Recovery Mode, turn on the Mac and immediately press and hold ⌘ + R.UPDATED FOR El Capitan Final Release : WORKS 100% ! The ambiguity of that last statement is I did that awhile before writing this comment, and I don't recall what I booted into first, only that it worked and was not hard to figure out what to do at that point. ![]() Installation will continue, or you will boot into the OS or get the Recovery Utilities menu (where macOS can be reinstalled from or Disk Utilities run). If the recovery partition isn't present and valid, these instructions won't work.Ĭlick the second entry. If the second partition isn't the recovery partition, look under the paths in the list to see if one of them is it. The second PCI path is probably to the recovery partition, the one you need to boot from. The first PCI path in the list is probably the boot partition that doesn't contain bootable firmware. ![]() You should see two entries in a list (they are cryptic-looking PCI bus paths). Select Boot Maintenance Manager and click. You'll be brought into an EFI text-mode GUI. I was able to fix the UEFI problems as follows (credit to the VirtualBox forum): After manually directing EFI to boot into macOS for the first time, macOS automatically fixed up the boot partition, and subsequent boots worked properly. In my case, after installing macOS into a virtual machine according to these instructions (running the macOS installer from an ISO image downloaded from Apple), on first boot, the boot partition was present, but unconfigured (probably no boot image installed). By now you may have surmised boot.efi is an EFI standard filename that lives at an EFI standard path in a disk partition, and it contains OS-specific boot firmware (e.g., Windows, Linux, etc. Ultimately, the objective is provide a boot partition that contains a macOS boot.efi. Your immediate objective is to help EFI locate and execute OS-specific boot firmware. However, assuming you have a macOS recovery partition on that disk, it should contain a copy of boot.efi (macOS-specific boot firmware) that you can boot into the OS with. UEFI requires intervention, because the EFI firmware on the Mac's motherboard can’t find valid OS-specific EFI boot firmware in the standard location on disk. ![]()
