If an application freezes

Try these solutions:

  • Restart your computer by choosing Apple menu > Restart.

  • Restart the computer in safe mode. For more information, see:

    Starting up 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 (in the Utilities folder in your Applications folder, or on your Mac OS X installation disc) to repair the 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.

  • Use Apple Hardware Test. (If your computer came with an applications installation disc, Apple Hardware Test is on that disc; otherwise, it’s on the Mac OS X installation disc.) Insert the disc, and then restart your computer while holding down the D key.

    If you just installed hardware, such as additional memory, Apple Hardware Test can tell you if it’s incompatible, improperly installed, or defective. If you can’t find Apple Hardware Test, take your computer to an Apple Authorized Service Provider.
