Has anyone been able to get Big Sur to work on a Dell Latitude E5510? I have been trying to create a proper EFI file for this setup and have not been successful. Here are the specs to my system: Intel Core i5-450M 2.40 ghz Intel GMA HD/1st gen Intel HD Graphics 16GB DDR3 SDRAM IDT 92HD81 audio Broadcom Wireless Any information would be great. Thanks in advance.
