OS X El Capitan
Hi, running OS X El Capitan v 10.11.6 & was running fine until yesterday when it has frozen & won’t allow me to do anything. Asking for keychain Password but the password I’m typing isn’t working. Can’t get into keychain manager to change, as crashes as soon as I try to make changes. Also can’t update to newest version of OS as it freezes when I type in my password. Unable to open Safari, Mail etc. Would love to hear if anyone has tips for fixing as there is a 7-10 day wait at local computer store!!! Thank you
