IPhoto crash

Boot into Safe Mode (Use Safe Mode to isoloate issues with your Mac and Playing Safe: what does Safe Mode do?) and try scanning from there. Then reboot normally and try again.

NOTE: Safe Mode boot can take up to 10 minutes as it's doing some system cache cleaning, volume verifying and directory repairing. 

There are 9 different versions of iPhoto and they run on 14 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. Include things like:

- What version of iPhoto.

- What version of the Operating System.

- Details. As full a description of the problem as you can. For example, if you have a problem with exporting, then explain 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.

If it's iPhoto and if it's on 10.14 then it can only be v9.6.1

Little test:

Create a new library. Import a few pics, see if it works - including editing. 5 or 10 pics is plenty. Hold down the option (or alt) key and launch iPhoto. From the resulting menu select 'Create Library'. You use the same command to switch libraries.

This test will allow us to judge if the issue is with your Library or the App.
