Thank you DGPickett.
I'm quite new to this so I don't try to get ahead of myself but I will try reading and understanding it.
Again
I've just made a simple script in AppleScript-editor that tells a driver to enable a device and saved it as an app. (rather than start terminal and enable it from there) I've manually replaced the Icon of the app in it's content. I want that Icon to change to another Icon when the process complete.
It's a small step, but eventually there is going to be a lot more to it.
I also want the icon of the app to change back to the default icon when the device is turned off. But I think it requires the source code of the driver and most likely more programming language
( Chances are that it isn't even possible to do so, because the device is officially unsupported )
