Some things to try on yur Mac.
Restart your Mac and depress the Shift key during startup. This will boot the Mac into Safe mode, which "fixes" some problems. Then restart normal.
Have you repaired Permissions?
Uninstall iTunes and then reinstall.
How To Completely Uninstall and Remove All Traces of iTunes
iPad not appearing in iTunes
iOS: Device not recognized in iTunes for Mac OS X
iOS: Device not recognized in iTunes for Windows
iTunes for Windows: iTunes can't contact the iPhone, iPad, or iPod software update server
iTunes for Windows: Device Sync Tests

Apple - Support - iPad - Syncing
iTunes 10.5 and later: Troubleshooting iTunes Wi-Fi Syncing
iOS: "Not enough free space" alert when trying to sync
On your iPad, Try this - Reset the iPad by holding down on the Sleep and Home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons. (This is equivalent to rebooting your computer.) No data/files will be erased. http://support.apple.com/kb/ht1430
I tried the following:
-I restarted my MAC in the Safe mode, and then restarted normally.
-I repaired permissions
-I "rebooted" my iPad
-I attempted to delete iTunes, but the message on my MAC was, "cannot modify or delete iTunes"
After each step, I tried to sync. iTunes goes through all the steps and then on step 6 of 6, it states "waiting for changes to be applied" for about 30 minutes and then it cancels the sync.
Thanks for any further advice.
I finally decided it must be a problem on my iPad.
I went to settings,
-erase all content and settings
I completely erased my iPad, then when I went back in I set it up by connecting to iTunes on my MAC.
So, now I have photos in my iPhoto app, and it is syncing properly.
Thanks for your suggestions!
