When I open window in a program, I typically want it to take up my entire screen (but not be in full screen mode, just maximally sized)

Instead, there is a thin gap at the left edge of the screen. It seems like the edge it is on follows the dock, as my dock is on the left edge, and if I move the dock to the right edge, the gap moves to the right edge. but whatever is causing this, I have to use a shortcut to remove that thin gap every time I open a window (I use a 3rd party app to make it quick but I'd still like it to "just work" when I open the window). Does anyone have any solutions to change this behaviour?

As a recent Mac convert, I completely feel the pain of unmaximized windows. I get why this works for some, especially long time Mac users and never-did-Windows folks. But for me, this was a serious pain, along with all the other nuances I've been suffering through during an incredibly busy work season as well.

I just discovered an app called GreenOrbmax, which basically reworks the green + button in a window to make it maximize, in the same manner in which I was accustomed to in Windows.

This might not be the solution you desire - if you find one, please post it, because I'm in. But this seems to be a reasonable solution for now, and since you didn't specify what 3rd party app you were using, I thought I'd share it with you.

Note: it does not seem to maximize Preview windows 100%.

  • The App I'm using is BetterSnapTool. I have a shortcut to maximize a window but I would prefer to not have to use it on every single window.
