Sorry, that I cannot provide a good review as I'm not really into the OSX API, thus my review here might look a little bit nitpicky.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">General comment: maybe rename the directory from "osx" to "cocoa"? After all it's more about the windowing system than the operating system.</p></pre>

This RR presents a "backport" of the modified KDE4 KWindowSystem implementation that has been used in the MacPorts kdelibs4 port for the last 2 or 3 (or more) years.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">I have made some initial steps to remove deprecated Carbon API calls, but this is clearly a work in progress.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">Open questions include
- is there any justification to run an event handler (or Cocoa observer) to keep track of running applications, possibly even listing all their open windows?
- is there any use for the Qt event listener framework (cf. the NETEventFilter in the X11 plugin)? I haven't yet had time to try to figure out what this "could be good for", and am very open to suggestions in this departments.
- one application for such an event filter would be a listener that catches the opening and closing of all windows by the running process, and keeps track of their <code style="text-rendering: inherit;color: #4444cc;padding: 0;white-space: normal;margin: 0;line-height: inherit;">WId</code>s. A new method could then be added (to <code style="text-rendering: inherit;color: #4444cc;padding: 0;white-space: normal;margin: 0;line-height: inherit;">KWindowInfo</code>?) to distinguish <code style="text-rendering: inherit;color: #4444cc;padding: 0;white-space: normal;margin: 0;line-height: inherit;">WId</code>s created by the running application from "foreign" ones (useful also on Wayland and MS Windows).</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;"><code style="text-rendering: inherit;color: #4444cc;padding: 0;white-space: normal;margin: 0;line-height: inherit;">KWindowSystem::setMainWindow</code> should become a front for payload provided by the plugins. I'll leave that to the regular/official maintainer(s) of this framework.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">This code could probably do with <em style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: normal;">lots</em> of comments; I'll try to add them as questions about this or that bit of code arise.</p></pre>
