Image Capture screen always opens with a small screen

Here is an AppleScript that you can use to open the Image Capture app with whatever size you wish. Just change the numeric values for xSize & ySize. You can also move the position of the window opens by modifying xPos & yPos.

set theApp to "Image Capture"


tell application theApp
	activate
	reopen
end tell


set xPos to 0
set yPos to 0


set xSize to 1800
set ySize to 500


tell application "System Events"
	tell process theApp
		set position of front window to {xPos, yPos}
		set size of front window to {xSize, ySize}
	end tell
end tell

Just curious what may be missing from my solution?

You can convert the script to an "app" when you save it. If you have already saved it as a script, then re-open it and hold the Option key when you click "File" so that you get the hidden "Save As...." option. Use the drop down list box on the Save dialog & select "File Format:" as "Application" so double-clicking on it will behave just like a regular app.

Unfortunately Image Capture is one of those apps which don't have any customization settings. I had to dig a bit to find how to resize it with the Apple Script. If Image Capture had been scriptable, then I could have given you a three line script.

I have only recently dabbled with some of the macOS AppleScript & Automator actions. If something is missing from my solution, it may be possible to do more with it although it may be out of my skill set at the moment. Maybe someone else will see your thread and have a better option.
