OS X Lion: If an application quits unexpectedly
This article has been archived and is no longer updated by Apple.
There are several solutions you can try.
- Reopen the application by clicking Reopen in the dialog that appears when the application quits.
- Restart your computer by choosing Apple menu > Restart.
- Restart the computer in safe mode.
- Uninstall any plug-ins or enhancements from other manufacturers for the application. If you’ve recently updated the application or Mac OS X, a plug-in or enhancement you previously installed may no longer be compatible.
- Read the application’s documentation (including Read Me notes) to check if it’s compatible with your version of Mac OS X.
- Open another document in the application. There may be a problem with the document you were trying to open.
- Use Disk Utility to repair your computer’s internal disk.
- Check to see if any updates to your software are available by choosing Apple menu > Software Update. For applications not made by Apple, look for updates on the manufacturer’s website.
- Disconnect any peripheral devices you just connected (for example, a printer). They may not be compatible with your version of Mac OS X. If disconnecting the device solves your problem, contact its manufacturer.
- Restart the computer into Apple Hardware Test. Apple Hardware Test can tell you if hardware you installed, such as additional memory, is incompatible, improperly installed, or defective.
- If you can’t find Apple Hardware Test, take your computer to an Apple Authorized Service Provider.
