multiple display setting to keep apps on each screen

I've used multi-monitors for decades now, I too was challenged with the fact that apps would not stay on the assigned monitor like they used to in Mountain Lion.

Here is the fix that worked for me and you still have all the Maverick function without unchecking anything.

Mavericks now considers each monitor a "Space". As a result, apps launch and have their menu bar in whichever monitor they were launched from. However, it's easy to assign apps to each monitor. Here's how:

First, you need to create an additional space "Desktop 3" in Mission Control. You can add it to either monitor.

Having done that, then when you right-click on an app in the Dock, you will see the option to assign the app to All Desktops, Desktop on Display 1, Desktop on Display 2.

wow... all this time and i had no idea about the right-click "assign to" option.

thank you all for this eye-opener.

Given that standard Mav behaviour invokes essentially two spaces, Apple need to build 'assign to' into the standard setup without having to initiate a third space.

This was driving me crazy and this (and no where else on the web I could find) fixed it for me!

anybody knows how to make it remember the position too? It always pops up in the upper link corner. In 10.8 the apps saved their desktop and position.
