mpotturi Posted November 1, 2018 Share Posted November 1, 2018 Hello Jake or other gurus... I am trying to install Mojave on Precision 5520. I am having hard time getting my installer to boot. It displays apple logo and the progress bar and when it reaches about 60%, it displays the prohibited sign in the middle. I tried verbose flag and the result is the same with the screen output getting garbled once the prohibited sign shows up. Here is my EFI capture. EFI.zip CPU: i7 6820HQ GPU: HD530 & Nvidia Quadro M1200 Mem: 32Gb Disk: 500Gb Update: I was able to get to the installer finally after checking the FixHeaders flag and connecting the USB drive thru a USB2,0 hub (my usb drive & port are 3.0). I was also missing WhateverGreen.ketx that I copied into ketxts/other folder. Link to comment Share on other sites More sharing options...
