seskanda Posted May 27, 2020 Share Posted May 27, 2020 I have Dell Latitude E6430 A13 BIOS with NVIDIA NVS 5200M and like to install Yosemite 10.10.3. I have Optimus turned off in the BIOS. My USB of Yosemite 10.10.3 has Clover on it, but installer never loads and goes to Black screen then reboots. SATA is set to AHCI, Secure boot off, Boot List Options is UEFI, and Legacy Option ROMs are on too. Thanks in advance Link to comment Share on other sites More sharing options...
seskanda Posted May 30, 2020 Author Share Posted May 30, 2020 Only 28 views in three days I doubt nobody knows why installer gives black screen and then reboots. Any help would be appreciated. Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted May 30, 2020 Moderators Share Posted May 30, 2020 Boot with verbose + debug=0x100 mode so you can get a clue to why it's rebooting. At Clover gui, press the spacebar, then select the boot option. Post the KP Link to comment Share on other sites More sharing options...
arsradu Posted May 30, 2020 Share Posted May 30, 2020 For Yosemite, I think you also need boot-args: "kext-dev-mode=1". Link to comment Share on other sites More sharing options...
seskanda Posted May 30, 2020 Author Share Posted May 30, 2020 I tried booting with -v but it still goes to black screen and reboots. It's hard for me to see any errors in all the text that shows up. But I will add some pictures of it here. When I press spacebar, I cannot edit anything but it lets me boot in verbose mode. I had to click the small 'options' button on the bottom to add 'debug=0x100' but that made things worse, and stays in black screen for good. The 'kext-dev-mode=1' is already in there so that will not do anything here. I have limited experience with hackintosh but my hunch is it is not detecting the display/screen or video card. My resolution is 1366x768 if that is useful. Link to comment Share on other sites More sharing options...

Moderators Jake Lo Posted May 31, 2020 Moderators Share Posted May 31, 2020 Last file on the bottom of guide is the EFI folder Link to comment Share on other sites More sharing options...
seskanda Posted May 31, 2020 Author Share Posted May 31, 2020 So you mean to replace EFI folder on my USB with the one that is inside zip file in that linked guide? Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted May 31, 2020 Moderators Share Posted May 31, 2020 Probably not since the Clover files is old. Just replace the Config file, ACPI folder and Kext folders. Maybe update the kexts inside the kexts/Other folder too Link to comment Share on other sites More sharing options...
