Macs running OS X should recognize the camera as soon as it is hooked up via the USB cable and turned on. The default application is iPhoto, which will launch and import the photos from the camera's memory card. The originals should remain on the card.

If you want to use Nikon PictureProject to handle your photos, install it from the CD that came with your camera. CAUTION: Your OS X account must have administrator rights to properly install Picture Project.

After installing PictureProject, go to your Applications folder, find Image Capture and launch it. In Image Capture>Preferences, set the application the Mac uses when you connect a camera to PIcture Project Transfer. You'll find PictureProject Transfer in /Applications/Nikon Software/PictureProject. When that is done, your Mac will launch PictureProject Transfer when you connect your camera. You can import everything or pick and choose the ones you want. When you hit the Transfer button, copies of the photos will be loaded into PictureProject on your Mac.

I think you should try both iPhoto and PictureProject to see which you prefer. Both work well, but there are differences that might affect your preference.

Good luck!

I have a Nikon d60, it came with a USB cable, and a program called Nikon Transfer, for mac or windows. If you don't have a CD with yoru nikon coolpix, go to nikon.com (nikonusa.com) and go to the top where it says service and support, then go to download center

then go to nikon software

and download nikon 1.4.0 it will have a macintosh link in there

I just realized you have a coolpix 5000 not a D5000, im retarded. this may not work for you, but i hope it does. check back :D

You may have simply turned off the display. Find the right button (might be called "disp") and press it until the display comes back on. Failing that, take out the battery and hope the camera will reset itself.
