Formatted Macbook without logging out Icloud
Hi,
I recently formatted my macbook and gave it to my friend. however, I think I did not properly logged out my icloud account before formatting it.
my friend told me the macbook were asking to log in my icloud account.
Im worried if my photos and other datas were showed to my friend even though I formatted my macbook. If it asked my icloud account informtaion, does it mean my datas are all revealed? Does photos staying even after the formatting?
