Soterlll Posted July 11, 2023 Share Posted July 11, 2023 Hello! I have Dell Latitude E6530 which freezes mostly after wake up(sometimes when I put it to sleep), so I have to manually turn laptop off using a pwr button. Sometimes I can repeat Sleep/Wake Up cycle up to 2-3 times. Another time it hangs after the first wake up. What I tried: hibernation off, Opencore update,disable dGPU via SSDTs(currently using boot-flag -wegnoegpu). I've followed the guide from the FAQ to send debug report but couldn't generate report file(mount: / failed with 66). Also I've noticed that wireless networking indicator starts blinking when system freezes after waking.I link my EFI folder and IOreg logs. i7-3740QM 1366x768 screen 8GB RAM HD 4000 + NVS 5200M System: macOS Big Sur 11.7.8. Opencore 0.8.8 IORegistry.zip EFI.rar Link to comment Share on other sites More sharing options...
Administrators Hervé Posted July 11, 2023 Administrators Share Posted July 11, 2023 I experienced the same with Big Sur when using OpenCore on my E6230. See my guide. I never managed to identify the root cause. Switching to Clover with what was, in essence, an identical setup sorted the issue. I never went back to OpenCore on that laptop.

Soterlll Posted July 12, 2023 Author Share Posted July 12, 2023 I will try to switch to clover. Thank you. Btw, I've managed to get bootlog. May you check it for any issues? bootlog.rar Link to comment Share on other sites More sharing options...
Lost-Entrepreneur439 Posted July 13, 2023 Share Posted July 13, 2023 This just seems to be an OpenCore/Big Sur issue, you can either switch to Clover like Hervé suggested, or if you wish to continue using OpenCore, downgrading to Catalina fixed the issue for me.

Soterlll Posted July 13, 2023 Author Share Posted July 13, 2023 Can you share your EFI folder for Catalina? It would be very helpful. Link to comment Share on other sites More sharing options...
Lost-Entrepreneur439 Posted July 13, 2023 Share Posted July 13, 2023 I've since gone back to Big Sur and no longer have my EFI for Catalina, sorry. Link to comment Share on other sites More sharing options...
Soterlll Posted July 13, 2023 Author Share Posted July 13, 2023 I've figured out that Sleep working with this DSDT file(E6430,HD4000+NVS5200M). Now I need to find out what caused sleep issues using my original DSDT DSDT_ORIGINAL.zip DSDT_SLEEPWORKS.zip Link to comment Share on other sites More sharing options...
