Soterlll Posted October 10, 2023 Share Posted October 10, 2023 The laptop almost perfectly runs Big Sur, but i experienced this annoying issue: From time to time display goes dark following the apple logo on boot, and then the machine goes to sleep. After i wake it from sleep by pressing the power button, everything works fine. I used Herve's E6230 EFI folder( attached it), also used my own patched DSDT and SSDTs. Nothing helps to solve this problem. Specs: Dell Latitude E6530 with A22 Bios i7-3740QM 1366x768 screen 16GB RAM HD 4000 + NVS 5200M(disabled in SSDT-DGPU) System: macOS Big Sur 11.7.9 Clover v5144 EFI.rar Here my Ioreg and logs files with Patched DSDT(E6530). ioreg.ioreg logs.rar EFI_6530.rar Link to comment Share on other sites More sharing options...
