Additional instructions, that can be found in
Mac Help.
"To take a picture of the whole screen, press Command-Shift-3. To take a picture of part of the screen, press Command-Shift-4, then drag to select the area you want in the picture. To take a picture of a window, the menu bar, the Dock, or other area, press Command-Shift-4, then press the Space bar. Move the pointer over the area you want so that it's highlighted, then click. (If you decide you want to drag to select the area, press the Space bar again.) If you press Command-Shift-4 and decide you don't want to take the screen shot, press the Escape key. Screen shots are saved as PDF files on the desktop. If you want to put the screen shot in the Clipboard, rather than create a file, hold down the Control key when you press the other keys. You can then paste the picture into a document."
"You can also take pictures of the screen using the Grab application (in the Utilities folder)."
I have tried all the methods you suggested, as per help as well... All I get is a black screen. My older version of osx were no problem to capture the screen, but this one I get a destop file called picture 1.png, when I click on it - I get a black screen. No picture. Do I maybe need to change some settings in preferences?
I love the free version of SnapNDrag. It works great and is easy to use. I keep it in the Dock and it's no problem for me to open up this little app to do screenshots.
Thanks for the advice on snapNdrag. It works perfectly - but THE PICTURES IT CAPTURES ARE STILL ALL BLACK. I'm getting the snap, the jpeg, everything but a picture. This is so frustrating. Anyone have any suggestions on how to make a picture of the screen appear?
I guess I answered my own question. I shut off computer, turned back on, after the start up sound pressed shift until screen was up. Went into apple preferences, displays, and changed the display to less colours, less pixels. Now I can take screen shots from apple (cmd,shift,3) or snapndrag. But since nobody could tell me, I was forced to dig and search.
