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
System version please?
No (listed right under Mac OS X)
Click on the first icon in the Dock (the list of icons at the bottom of your screen) which is the “face” the "Finder", then click on Go at the top of the screen, you will see a drop down menu, go to Utilities. When that opens double click on the application called Disk Utility. When Disk Utility opens you will see your hard drive (usually Macintosh HD) on the left. Highlight your hard drive and click on Verify Disk on the far right. If that is OK in green type, then click on Repair Disk Permissions on the left.
Note: If Verify Disk is not OK try to Repair. If Repair is successful then Repair Disk Permissions if it is not successful let me know.
So Verify Disk was OK in green type and then you Repaired Permissions? If so Quit iPhoto, hold down the Option or ALT (if outside the USA) and Command keys and start iPhoto. Check all the boxes and run Rebuild. After try to upload your book again.
If you just stopped on the thumbnail cache rebuild then that should be ok but I would have let it finish first. I guess you can try now.
OK I can only suggest you restart and try again.
I can't find any direct number sorry:
Try changing you DNS servers to :
Go to System Preferences / Network choose your connection type then go to Advanced select the DNS tab
Have you ordered prints before? Not Network Diagnostics, I said System Preferences / Network choose your connection type then go to Advanced select the DNS tab and then the plus sign to add each server. What version of iPhoto is it? Make sure you are using iPhoto '09 or later. Earlier versions of iPhoto can no longer order print products. Certain third-party Anti-virus and system cleanup apps, such as MacKeeper, can interfere with iPhoto ordering. Make sure these apps are disabled.
Hello there! Try the following if you still cannot get a solution.
OK go to iPhoto / Preferences / Accounts and remove your Apple account then quit restart and add it back. Also make sure you have sufficient bandwidth to complete the order. iPhoto requires approximately 1.5 Mb/s to avoid timing out during the order process. Unplug your router and / or modem from power for a few minutes then plug back in and Go here to test:
Upgrading to Yosemite and the newer iPhoto as well as Photos the new version and replacement for iPhoto might solve you problem too.
