mengshi Posted October 8, 2025 Author Share Posted October 8, 2025 I just tried a very minimal EFI (Containing essential kext and drivers only) and the point of failure is exactly the same - for Sonoma and Sequoia. So I think it could be at the SMBIOS level.

mengshi Posted October 13, 2025 Author Share Posted October 13, 2025 I think my issue could be due to the target installation SSD is not at Sata Port 0. So will change and try later. Did know this could be a factor.

mengshi Posted October 30, 2025 Author Share Posted October 30, 2025 Problem is solved. Problem is due to the target installation SSD not being on the first SATA port.
