Please go to the Apple logo at the upper left of your computer screen to About This Mac and give me this information: The exact system Version (listed right under Mac OS X) Processor Memory
Hello there! Please accept the phone off and I will be happy to call right away.
Sounds good ill be here.
If you are running Lion or above start by checking this:
Reboot into the Recovery HD by choosing the ‘Apple‘ menu > Restart, then hold down the ‘Command’ + R’ keys on the keyboard during the start up process. When you see the Apple Logo you can let go. When the machine boots you may have to choose your language then you will see the OS X Utilities screen. Select the Disk Utility and then select Continue. Then in Disk Utility select Macintosh HD in the left column (if there are two with that name or it is named something else choose the first indented item) and then Highlight your hard drive and on the right select the First Aid tab if it is not already selected, then click on Verify Disk on the far right. If that says “OK” in green type then select Repair Disk Permissions.
If all is ok restart then hold down the Option or ALT (if outside the USA) and Command keys and start iPhoto. This will bring up iPhoto First Aid check all the boxes and run Rebuild or just Rebuild depending on the options. Let me know after.. or you can Accept the Additional Service offer for remote tech support and I can do it for you.
