jcmrdc Posted November 18, 2020 Share Posted November 18, 2020 (edited) Hello everyone, I've successfully installed macOS Big Sur 11.0.1 on my PC, dual booting with Windows 10 Pro. Everything works perfectly out of the box, EXCEPT that the Windows clock stops at shutdown and I have to manually resync it every time I reboot into it. This issue does not occur on Big Sur because the OS syncs the time after login. Any ideas on how to solve this most annoying issue? My hardware specs: ----------------------------- Motherboard: Gigabyte Z390 M Gaming (latest BIOS FL9) Processor Intel Core i7 9700K 3,6GHZ Memory: 64GB of Corsair Vengeance LPX 3000MHZ DDR4 RAM (2x32) Internal storage: 2 TB (2x1) NVMe WD_750 Black GPU: Gigabyte Radeon RX 590 8GB Connectivity: Broadcom Wi-Fi/Bluetooth combo PCI card What I have tried: ------------------------- 1. Change Windows 10 to UTC time; 2. Turn off Windows 10 automatic sync with Internet time; 3. Turn off Windows 10 automatic time zone; 4. Turn off macOS Big Sur automatic sync with Internet time; 5. Check ALL BIOS settings; 6. Replaced the BIOS battery with a brand new one.  Thanks a million!  Edited November 18, 2020 by jcrcarmo Quote Link to comment Share on other sites More sharing options...

jcmrdc Posted November 18, 2020 Author Share Posted November 18, 2020 I just did. I'm already using SSDT-OLARILA.aml so should I delete it and replace it with one of AcidAnthera's SSDTs? Thanks. Quote Link to comment Share on other sites More sharing options...
