Take screen captures. There are keyboard shortcuts to capture a screen image (if you can remember them). And, there’s the Grab app in the Utilities folder which seems more a remnant from the last century.
If you really want an easy way to grab a screenshot, or an image from an app, and get a few more useful features Apple doesn’t provide, use my favorite– SnapNDrag Pro.
What you get is a dedicated Mac app which blends the basics of screenshot capture with features you want. Change the file format. Adjust the .JPG quality. Add a border. Resize. Change the file name.
Oh, and SnapNDrag Pro uses drag and drop to send an image from Apple’s Mail.
Wait a minute. Doesn’t that SnapNDrag screen look ominious and clumsy? Never fear. There’s an even easier way to snap screen shots.
Use the Mac’s Menubar.
Instead of worry about keyboard combos, or a dialog box, simply setup SnapNDrag Pro with the options you need, and use the Menubar to capture screenshots.
SnapNDrag captures images and stores them by date which makes it easier to find screenshots and easier to manage the files. Not bad for a few bucks.
