hi Yesterday I received a 2FA Message from apple that someone in Chicago IL wanted acces , because I live in the Netherlands I denied this , no other message with a code popped up, but within seconds all my macs ( in 2 locations, 1 Mbp , 2 minis and 1 imac) all went in to lost mode . 2 of them ask for six digit pass codes and 2 of them for four digit codes . My iOS devices linked to the same account remain untouched seemingly. I immediately changed my password in ICloud , but cannot get these macs out of lost mode . The grey screen stays, From ICloud.com I am still able to play a sound on these macs but that's all. The grey screen gives a message that i should write to firstname.lastname@example.org , but I do not expect help from that side . Apple support saw this behavior more , suspects "Russian hackers" but do not have a solution other than go to an apple service point , but they do not open untill Monday , so I'll guess I have extra time on my hand this weekend Any thoughts about bypassing this ?
