DarkArrayLord Posted June 30, 2019 Share Posted June 30, 2019 Hello guys hope you are all well. Could someone give me some pointers on how to advance with the installation of Mojave on my Dell Latitude 5490? I have been following many tutorials here and from other sources but my installation always gets stuck on the dreaded 2 minutes mark with the following message: efihelper_block_invoke_2: Connection Closed. I have formatted my SSD as APFS and also tried with Journaled, BIOS settings are as described in the tutorials. My configuration is: Processor: Quad-core Kaby Lake R i5 8250U @1.6GHz RAM: 16GB Graphics: Intel UHD Graphics 620 Video Memory: 64MB (this seems to be set and I cant change) BIOS version: 1.7.0 Audio Controller Realtek ALC3246 (=ALC256) Wifi: Intel I have attached my EFI folder and another file with all the KEXT and EFIs files I could find and test. This is one of the tutorial's I have followed: I have combined the generic EFI folder with 7480_Mojave.zip. I'm following this thread EFI_Latitude5490.zip Other.zip Link to comment Share on other sites More sharing options...
Administrators Hervé Posted June 30, 2019 Administrators Share Posted June 30, 2019 You could have followed this guide too, it may be more appropriate than the 7480. Link to comment Share on other sites More sharing options...

DarkArrayLord Posted July 2, 2019 Author Share Posted July 2, 2019 Hey Hervé, good night. I have followed the tutorial, but I still get stuck at the same moment I'm attaching my EFI folder along with pictures from my boot options of clover, install log error and BIOS general settings. If you can give me some light of where to go I apologize for the inconvenience, your help is very much appreciated. EFI.zip Link to comment Share on other sites More sharing options...
Administrators Hervé Posted July 2, 2019 Administrators Share Posted July 2, 2019 What partition scheme did you use on your target SSD when you reformatted it? MBR or GUID? Should be latter, nor former. Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted July 2, 2019 Moderators Share Posted July 2, 2019 PM981 NVMe is known to cause hangs and automatic shutdown on MacOS. No fixes for far, recommendation is to get it replaced with known supported NVMe drives or M.2 SSD. Link to comment Share on other sites More sharing options...
DarkArrayLord Posted July 3, 2019 Author Share Posted July 3, 2019 I'm formatting as APFS:GUID. Link to comment Share on other sites More sharing options...
frikeando Posted July 19, 2019 Share Posted July 19, 2019 I have the same laptop and used the manual Hervé linked, everything worked perfectly, except the trackpad buttons. Link to comment Share on other sites More sharing options...
DarkArrayLord Posted July 19, 2019 Author Share Posted July 19, 2019 Hey, golosin2 thank you for your comment. Would you mind sharing your EFI with me? I have tried many drivers and configs cant make it work. Do you have the same SSD or did you change to another one? Also, did you change something on your BIOS Settings? Updated/Downgraded the firmware? Is your USB stick 3.1? PS: Sorry for all the questions I'm trying to pin down what I could be doing wrong.
