What size are we setting the window to be?
I think the window size needs to be configurable.

The return of "defaults read com.apple.Safari ...' is a list contains 8 numbers. And the last 4 numbers indicate the largest screen size, while the first 4 number indicate current configuration. If you overwrite first 4 numbers with the largest value, the safari will launch to maximum window.

Was this really reviewed already? r? flag is set. Also, you are missing the period at the end of the sentence.

Maybe a changelog to explain why this is needed and what you mean by fixing the Safari Window size?

Which corner? I could use something like "moveCursorToTopLeftCorner". Or a more generic "moveCursor(x, y)" that takes coordinates in parameters.

We may want to move this code to a function with a clear that so that it is clearer what it does.

Do we really need to call subprocesses for this. I believe there are pythonic ways of doing this (NSUserDefaults.standardUserDefaults()). Maybe this is useful:

moveCursorTo(x,y) is a better name for my second proposal, sorry.

> +    def getScreenSize(cls):

In WebKit, we use "get" prefix only when we have an out argument.
See http://www.webkit.org/coding/coding-style.html#names-out-argument

So this function should be "screenSize" instead.

Please use named format e.g. '{width}{height}'.format(width=~, height=~).

You shouldn't fill this up until you get r+ because it implies I've already given you r+, which I haven't.

Can we instead make self.screenSize() return a dictionary with width/height as keys?

Instead of duplicating calls to closeBrowsers and moveCursor here, why don't we just call super(OSXSafariDriver, self).prepareEnv() ?

Can't we just use self.screenSize here instead of user defaults craziness?
