    Lenovo ideapad 330S / Win10 / Virtualbox 6.1.12 / macOS Big Sur Beta 4 / Pub B1 / OS Boots, Safari works, can’t log into iCloud. Can’t log into iMessage. Can’t log into account in Settings. I find it strange that I was able to get it to boot up, surf Safari, everything is quick and seems like it works – but no Apple services. I was able to change the Serial via CMD to a 12 digit serial that took…it now shows in “About.” What am I doing wrong or not doing? I want this to work so badly. Thank you to anyone willing to offer a suggestion. I did search for DAYS before deciding to ask online. Please let me know if you need any more information.
