And if that didnt work, use the Open With feature I mentioned in this tip.) Once Preview opens, if you dont see the toolbar with the Instant Alpha magic-wand icon, click on the Markup button to reveal it. Then the tooIbar will shów up, and yóu can use thát Instant Alpha óption. Youll click and drag within the background of your image, and as you drag further, Preview will select more and more and will highlight it in pink as you go.
