Hello, new to mac here and loving it i've found the transition easier than thought. I use my new macbook to mostly deal with pics. I need to make all my new pics open default with Ipreview when i double click them instead of with Photoshop.. I know i could click on the file options and go to open with and open it with whatever program i want. I need to be able to double click it and have it open with my desired program. Thank you for any help you're able to shed.
