Q I need to access important information that I recorded in Evernote 2.0, back in 2009. However I cannot access it using my original password, and cannot find its files anywhere, even in Time Machine. Are they lost?
A Older versions of Evernote, not purchased through the App Store, keep their documents in ~/Library/Application Support/Evernote, although some might use ~/Library/Application Support/accounts/Evernote. Time Machine backups should use the same path, unless you have excluded it from being backed up.
iOS is different, as it uses that named online Evernote account unless you have a Premium Account subscription.
If all else fails, try contacting Evernote support, who may be able to enable your access to online copies.
