iPhoto won't start - what to do?

If you can't start iPhoto on Mac OS, just follow the tips below to get the tool working properly again:

• There may be problems with the iPhoto database. Start the program with the [Alt] key pressed and then create a new database by clicking on "Create new database".
• If this does not help, you should create a new user and start with this iPhoto. If that works, there may be a problem with the other user account.
• You can therefore try to have the access rights repaired. To do this, you must hold down the [Alt] key again when starting and select the "Repair access rights" item.
• Then click on the "Repair" button. Note that this process can take some time.
• In many cases there are also problems with the settings of iPhoto. Therefore open the path "~ / Library / Preferences /" and delete the file "com.apple.iPhoto.plist". Then you should empty the trash.
• There may also be an update available for your system that corrects this problem. To find out, click the Apple logo at the top and choose "System Update."
• If you cannot solve this problem with the tips above, you can try to import a backup from the Time Machine.
