Hello,

I've been researching for a day or two but can't find a method to take a screenshot of a specific window (possibly the only window) open at a specific time using an Apple script.

Currently I have the script execute

screencapture -T1 ~/Desktop/screenshot.png

But what I want is really

screencapture -wx -T1 ~/Desktop/screenshot.png

But when I use -wx, it waits for a mouse click on the window.

Are there any utilities, built in or not, that will allow me to do this?

Thank you so much!

(I'm sorry if this belongs on Stack Overflow, can someone move it if it does. It kind of overlaps both super user and stack overflow.)

Edit: The windows alternative that I'm looking for on a Mac is the keyboard shortcut:

Alt + PrntScrn
