A Mailbundle to disable the Send- and Reply-animations on OS X 10.9 Mavericks and 10.10 Yosemite

No Animations on OS X 10.9 Mavericks and 10.10 Yosemite

A Mailbundle plugin to disable the Send- and Reply-animations on OS X 10.9 Mavericks and OS X 10.10 Yosemite. Run on your own risk. When having issues, please remove the Mailbundle again.

How does it work?

This Plugin disables animations in 10.9 and 10.10 by swizzling's -[DocumentEditor shouldDoPopOutAnimation] to return NO always. To disable the send-animation, we swizzle -[DocumentEditor _performSendAnimation] to directly call -[DocumentEditor __sendAnimationCompleted]
