Evernote Account Switcher makes it possible to use multiple Evernote Accounts for the Evernote Mac Client. The default Evernote Client doesn't allow you to easily switch between different Evernote accounts.
What's new in Evernote Account Switcher
Completely redesigned autologin feature. Should be much more stable and faster!
Updated to work nicely with the latest version of Evernote.
EAS now waits for Evernote to really quit. This is needed when Evernote syncs upon quiting.
Auto update now checks only once a day instead of every time at launch
