Moderators Jake Lo Posted March 17, 2020 Moderators Share Posted March 17, 2020 try this boot arg -wegnoegpu @MrJonesIII A few posts back you mentioned replacing ACPI and Kexts folder, did you replace the Config file as well? Link to comment Share on other sites More sharing options...
MrJonesIII Posted March 17, 2020 Author Share Posted March 17, 2020 Yes, I replaced the two folders and the config file from within that folder with the ones in the zip file. -wegnoegpu argument did not work. BIOS setting I'm missing? Link to comment Share on other sites More sharing options...
MrJonesIII Posted March 17, 2020 Author Share Posted March 17, 2020 Hi Jake. Just reading through this again and you mentioned I should stick with MBP15,2 because I had a Coffee Lake model, but the processor that shows up in the Linux HW Probe is Core i7-8565U CPU @ 1.80GHz, which is actually Whiskey Lake. Which CPU should I be choosing in this case? Link to comment Share on other sites More sharing options...
MrJonesIII Posted March 17, 2020 Author Share Posted March 17, 2020 (edited) Found another person who managed to have success with the same Whiskey Lake Core i7-8565U CPU and Intel UHD620 as my E3400 on another site (see EFI attached) and this one seems to go a lot further without hanging, but I get the dreaded white circle with the line through it when the progress bar gets to about 75%. This was a Dell Inspiron 7580, however. EFI 2.zip Edited March 17, 2020 by MrJonesIII Added more info on the source. Link to comment Share on other sites More sharing options...
MrJonesIII Posted March 19, 2020 Author Share Posted March 19, 2020 This Latitude 3400 keeps restarting when I try to format the internal hard disk, which is a 1TB Samsung PM981 NVMe. Windows and Linux both format and install on it fine. Any ideas as to why this might be happening? Anyone seen this sort of thing before? Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted March 19, 2020 Moderators Share Posted March 19, 2020 The drive ( Samsung PM981 ) is known to be incompatible with MacOS. Replace with something else. 1 Link to comment Share on other sites More sharing options...
MrJonesIII Posted March 26, 2020 Author Share Posted March 26, 2020 I've replaced the Samsung with a MicronNVMe SSD, but I can't seem to even get to formatting the drive any more. I'm now getting the "In Memory Panic Stackshot" error. I've tried upgrading Clover to r5107 from 2.5_r5103, Apto Memory Fix, one of the other Apto memory fixes, but it's just restarting with that error every time. I've tried Mojave, Catalina, 15,1, 15,2, 15,3. I'm at a loss here. I have taken a video of the boot up (https://www.dropbox.com/s/clywn5b56766dir/IMG_3406.MOV?dl=0). Any help would be greatly appreciated. Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted March 26, 2020 Moderators Share Posted March 26, 2020 add to boot arg by going to Option from Clover GUI or edit Config.plist and add under Boot -v debug=0x100 -igfxvesa Link to comment Share on other sites More sharing options...
JmW Posted March 26, 2020 Share Posted March 26, 2020 Hi @MrJonesIII EFI of working Catalina. EFI_Working.zip Link to comment Share on other sites More sharing options...
MrJonesIII Posted March 26, 2020 Author Share Posted March 26, 2020 @JmW - Thank-you! @Jake Lo - Thanks to you too. I used JmW's EFI folder, put in known good serials and entered those boot arguments. It is still bombing out with - ** In Memory Panic Stackshot Suceeded ** Bytes Traced 266688 ** The number after bytes traced changes each time.
