I’m trying to automate the set up of VirtualBox on a large deployment of MacBooks.

One of the tasks is to add an existing hard drive image to a new virtual machine.

I could not see any key combination to access that button so I figured I’d just use the click button command.

Code reads:
tell application “System Events”
… [lots of unrelated code here]
tell process “VirtualBox”
click button “Existing…” of window “Create New Virtual Machine”
delay 1
click button “Add” of window “Create New Virtual Machine”
end tell
end tell

I used the Accessibility Inspector to check the aspects of the button and it says:
Application: “VirtualBox”
Window: “Create New Virtual Machine”
Button: “Existing…”

AppleScript error is:
System Events got an error: Can’t get button “Existing…” of window “Create New Virtual Machine” of process “VirtualBox”.

Any ideas?
