My MacBook Pro (running 10.11.6) has a swollen battery, so I turn it off immediately and send it in for service. I have an updated backup (a bootable backup) created with CarbonCopyCloner. Mac maintenance will take a while (maybe a week or so).
Meanwhile, many of my passwords are unknown to me. They are mostly automatically generated random passwords, stored in either keychain access or in the Firefox password saving feature (or sometimes both). Obviously I know my login password and the passwords to unlock my keychains (although I often only use standard login keychain), but I do not know most other passwords.
Since I have access to email through other devices, I have could reset different passwords. But it would be a lot of trouble, and when I get my Mac back, I have to update the keychains and Firefox.
I have other computers running Linux (Ubuntu) and Windows (both 7 and 1
How can I get my passwords out of the keychain (s) and Firefox data from the backup?
(To be complete, I actually still have my laptop with the swollen battery since they send me a box in a couple of days to use it to send it. But I will really nor does it turn it on given the swollen battery and the potential for damage, plus I’m curious about this question for its own sake.)
