Hey, I've looked around a bit for answers to this question, but as it's not exactly one-dimensional a precise answer would be best. I'm basically wondering this: if a mac laptop is stolen or something, for example, can the thief reset the password using an OS X disk, then log into the account and into Keychain using the newly selected password and unlock access to all the other passwords? At this point, they could log into emails, social sites, finance sites (if passwords are saved), etc, essentially access EVERYTHING. I really hope this isn't the case, but it seems to me that it is from what I know (though I never tried this on my own macbook). A second part of my question is (if this is true) are there any ways to fully block out access to Keychain or prevent this from happening in other ways? I would activate encryption (FileVault) but performance takes a huge hit and as such can't really do so. Thanks in advance for your answers!
