Q: no Shake 4 and Motion 4 support in Yosemite

Apple Shake 4 works in El Capitan public beta. it seems to work fine. good news indeed.

Motion works perfectly with Yosemite

APPLE SHAKE still works in latest version of EL CAPITAN.

It needs a slight tweak, though.

1. Right-click SHAKE.APP;

2. Go to SHOW PACKAGE CONTENT;

3. Go to Contents --> MacOS --> shake (it's an exec file, together with tshake; don't use/click tshake);

4. Double-click 'shake'. It first opens Terminal Window and right after Shake 4.1 is in front of your eyes;

5. Create an alias (a shortcut) of the file and place it whenever you want. It can be Application folder, or desktop. It CAN'T be seen from Launchpad though.

A quick HOW_TO: Shake 4.1 in El Capitan - YouTube - (click it)

Happy SHAKING.
