bill10 Posted October 28, 2016 Author Share Posted October 28, 2016 To provide more information, when I boot with -v, the texts end as "DSMOS has arrived...IODisplayWrangler+ (1)". Then the apple logo shows up with a stuck progress bar. Is that the normal behavior? Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted October 28, 2016 Moderators Share Posted October 28, 2016 are you connecting through HDMI or DisplayPort or DVI? Avoid VGA if possible. Try the different video connection Link to comment Share on other sites More sharing options...
Administrators Hervé Posted October 28, 2016 Administrators Share Posted October 28, 2016 Many Dell workstations are configured with a PCI root set to 4. With default PCI root set at 0, bootloaders often can't initialise graphics cards properly until the value of 4 is specified. Link to comment Share on other sites More sharing options...
bill10 Posted October 28, 2016 Author Share Posted October 28, 2016 @Jake, the video card has only HDMI ports. I don't have HDMI cables at hand so I am using DVI cable with a DVI-HDMI adapter. I will get a HDMI cable and see if it works. Link to comment Share on other sites More sharing options...
bill10 Posted October 28, 2016 Author Share Posted October 28, 2016 @Herve I tried PCIRootUID=4 alone and PCIRootUID=4 with GraphicsEnabler=Yes or No. Still stuck at the progress bar. Here is the picture before the apple logo shows up. Note that the third to last line: ACPI_SMC_PlatformPlugin::start - waitForService(...) timeout Is that an error?

Administrators Hervé Posted October 28, 2016 Administrators Share Posted October 28, 2016 I would modify 2 things in your Clover config.plist: in Graphics tab, I'd select option "inject nVidia" in SMBIOS tab, I'd opt for iMac16,1 (Broadwell) rather than MacPro6,1 (IvyBridge) If you can, try and press F4 at Clover main menu to extract your raw BIOS tables and get them saved to CLOVER/ACPI/origin folder of EFI partition. You can then post us a zip archive of your DSDT and SSDTs. Link to comment Share on other sites More sharing options...
