TheRobster5555 Posted April 10, 2018 Share Posted April 10, 2018 I decided that I would hackintosh my newer latitude and I actually got the installer booted and everything, but no display. Since there's no 100% clear guide, I followed the 6220 guide hoping it would be close enough. When I boot the installer, it boots up fine, but when it escapes verbose, the screen flashes white, then nothing comes up, although it did boot as the hdd activity light is active. My 6420 has the 4200m and the 1600x900 screen. Link to comment Share on other sites More sharing options...
veedub89 Posted April 10, 2018 Share Posted April 10, 2018 Here's the best guide. You're going to want to use the E6420_Optimus_A23 bootpack for your 4200m. Link to comment Share on other sites More sharing options...
Administrators Hervé Posted April 10, 2018 Administrators Share Posted April 10, 2018 The key difference between the E6220 and your E6420 is that the former is limited to LoRes 1366x768 LCD whereas your laptop has a HiRes 1600x900 LCD. As such, you absolutely need to set/activate/tick DualLink in your Clover config (or set this through DSDT) if you run on the HD3000 iGPU. Once you've done that, you'll find your screen will work fine. Link to comment Share on other sites More sharing options...
TheRobster5555 Posted April 15, 2018 Author Share Posted April 15, 2018 I'm back after a while (had other things to do) and I've tried redoing the installer USB over and over, and nothing works, it keeps kp'ing. I cannot boot into the installer, can anyone help? Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted April 15, 2018 Moderators Share Posted April 15, 2018 did you follow veedub89's post? You'll need to enable Optimus in the BIOS Link to comment Share on other sites More sharing options...
TheRobster5555 Posted April 15, 2018 Author Share Posted April 15, 2018 I did, and yes, optimus is enabled Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted April 16, 2018 Moderators Share Posted April 16, 2018 Try replacing bootpack with this, goes into /EFI/Clover, overwrite your existing. Worked on HS, so it should work on Sierra as well E6420_Disabled-NVS_HS.zip Link to comment Share on other sites More sharing options...
TheRobster5555 Posted April 16, 2018 Author Share Posted April 16, 2018 I tried that bootpack, and same problem... here's a pic of the kp btw Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted April 16, 2018 Moderators Share Posted April 16, 2018 You are not booting from that bootpack. It's showing MBP8,1, the bootpack has SMBIOS set to MBP8,2 Check if you have an EFI folder on the root of your installer. Link to comment Share on other sites More sharing options...
TheRobster5555 Posted April 16, 2018 Author Share Posted April 16, 2018 That was the problem, I was just dumping everything into the efi partition, I guess I didn't read close enough. I got into the installer, I'll keep you updated... EDIT: Installation was successful, just need to patch the Wi-Fi kext to get the Wi-Fi working, I'll do that later. Something I noticed is that I couldn't find any trace of it recognizing the NVS GPU on macOS. Is this normal with optimus? Link to comment Share on other sites More sharing options...
