(please note that English is not my first language) So here is the thing: when I look at the changing date column of my apple Keychain I can see that most of the dates and times of my passwords have been changed (not the passwords itselves). The changes happend during a date and time i definitely wasn't at my computer. All the changes apparently occurd within seconds and I'm talking about 20+ passwords here. I am very concerned that I might got hacked. What do you think?
