gramturismo Posted December 30, 2016 Share Posted December 30, 2016 I made the USB installer and now I have it done with the proper e6530 bootpack, but every boot option I try only results in a black screen shortly after the Apple logo appears while booting. I can't even get a screen using verbose mode. So both the USB stick and HD install will not boot. It's so exhausting at this point, I even got to the installer but the mouse/keyboard wouldn't respond. I feel like it would be better to start over, but if anyone has experienced this please help! Thanks. Link to comment Share on other sites More sharing options...

Moderators Jake Lo Posted December 30, 2016 Moderators Share Posted December 30, 2016 What's the specs of your system? As Bronxteck comment, if you have both Nvidia and Intel HD, you need Optimus enabled. Nvidia can't be disable in the BIOS so will have to be disabled with DSDT.

gramturismo Posted December 30, 2016 Author Share Posted December 30, 2016 So I got past the black screen thanks to enabling Optimus. The BIOS is A07. It has Intel HD4000 and Nvidia NVS5200M. Here's the result when I boot from USB: Link to comment Share on other sites More sharing options...

Moderators Jake Lo Posted December 30, 2016 Moderators Share Posted December 30, 2016 See here, basically the same except E6530 has a bigger screen and number pad. Link to comment Share on other sites More sharing options...
gramturismo Posted December 30, 2016 Author Share Posted December 30, 2016 So if I'm understanding this... I mount the EFI partition on my USB stick and replace the Clover/ACPI/Patched/DSDT.aml with the 10.10 version? Link to comment Share on other sites More sharing options...
gramturismo Posted January 2, 2017 Author Share Posted January 2, 2017 Good news! I've been able to consistently boot from the HD using USBBusfix=Yes and GraphicsEnabler=Yes. USB keyboard and mouse are working as well as my external HD. I've been trying to fix graphics/audio etc... Link to comment Share on other sites More sharing options...
