I have a MBP

OS 10.7.5

2.4GHz Intel Core Duo

2GB 1067 MHz DDDR3

NVIDIA GeForce 9400M 256 MB

500MB HD


All software uptodate.


Upgraded to current OS last Feb since when I have all sorts of problems. Very slow especially iPhoto, Mail, Address Book. Had new hard drive installed - Apple store saying it was a HD problem. Laptop worked beautifully! Blisteringly fast. Then reinstalled everything from Time Machine and it all slowed down again. Apple store thinks there is a bug or 'strange file' somewhere in iPhoto. Opening iPhoto slows other apps even more. Beach ball seen everytime I use any app for anything up to a minute.


Used to have about 9000 photos in iPhoto. iPhoto has now created new photos with every face in every photo. So a group photo with 15 people in it has now spawned 15 photos. Also, almost every photo seems to have a duplicate if not a triplicate. iPhoto now had over 50,000 photos!!! Also, many photos are now just blank. When open them up a big ? appears. Scrolling takes forever. The process of opening and closing iPhoto takes nearly 5 minutes.


MacBook Pro, Mac OS X (10.7.5)

    As a Test:



    Hold down the option (or alt) key and launch iPhoto. From the resulting menu select 'Create Library'



    Import a few pics into this new, blank library. Is the Problem repeated there?

    Thanks for your advice Terence. Sorry for delay in replying. Have deleted about 3000 old photos as wella s many of the 'faces' created and duplicates. I did this on advice from Apple store who said that iPhoto does not cope very well with that number of photos. In fact they said 10,000 was probably the limit! Anyway, am now down to about 43,000 photos and this has has had a tremendous effect. Mail, Safari and Address Book are now back up to speed. iPhoto also alot quicker though could be quicker still. Will, plod on with deleting unwanted photos in the hope that this carries on improving the situation.

    The Apple Store you consulted with are talking through their collective hats.


    iPhoto up till iPhoto v5: Good for 25,000 in any library


    iPhoto v6 to v9: Good for 250,000 images in any one Library


    Since v9: Good for 1,000,000 images in any one Library.


    What happened when you ran the test, above?

    How much free space do you have on your MPB?
