Q: iphoto keeps crashing since installing new osx

Try repairing your permissions with disk utility.  Then give it a try. 

Could you give us any less information to work with?

Remember: we cannot see your machine. There are 9 different versions of iPhoto and they run on 8 different versions of the Operating System. The tricks and tips for dealing with issues vary depending on the version of iPhoto and the version of the OS.  So to get help you need to give as much information as you can. Basic things like :

- What version of iPhoto.

- What version of the Operating System.

- Details. As full a description of the problem as you can. For instance: 'iPhoto won't export' is best explained by describing how you are trying to export, and so on.

- History: Is this going on long? Has anything been installed or deleted?

- Are there error messages?

- What steps have you tried already to solve the issue.

- Anything unusual about your set up? Or how you use iPhoto?

Anything else you can think of that might help someone understand the problem you have.

Posts that consist of "iPhoto doesn't work. Help" or "iPhoto won't print" or "Suddenly I have no photos!!!!!!!!!!" mean that any helper is simply guessing. More information means you get better assistance.

Try repairing your permissions with disk utility.  Then give it a try.

Eric, generally the repair with Disk Utility is helpful, but  a photo library is best repaired with the specific build-in "Library First Aid Tools", not with the less specific Disk Utility. To repair the permissions in a photo library you'd better launch iPhoto with the key combination ⌥⌘ held down and select "Repair Permissions" from the resulting dialog panel.
