Hi all, a noob looking for any help please. I installed OS High Sierra on Dell Latitude E6220 Intel Core i5 2nd Gen 2.50GHz which runs fine (Jake Lo install i believe), but it continually freezes (seems random, runs fine then freezes 1 to 2 hours). I used Jake Lo guide - Jake provided some kext etc. for an e6220 i7 I had previously. My current model is an i5. could anyone help please. I have attached EFI EFI.zip nvram.plist.zip
