keychain access not responding

Hey there ianfarrar,

Is Keychain reflecting an error when trying to open or is it closing suddenly? If so, make sure you're using the latest macOS version in case this is software related. Use the steps here: Update macOS on Mac - Apple Support

You can continue with the guidance below if the app continues to close after updating:

* If an app doesn’t quit as expected, or it’s unresponsive, you can force quit the app (you may lose unsaved changes). Choose Apple menu  > Force Quit, select the app in the dialog that appears, then click Force Quit.

* If the app quit, reopen it by clicking Reopen in the dialog that appears.

* Restart your Mac by choosing Apple menu > Restart.

* Make sure the app is compatible with your version of macOS.

* Open another file in the app. There may be a problem with the original file.

* Check for updates to your software.

* Disconnect any peripheral devices you just connected (for example, a printer). They may not be compatible with your version of macOS.

* Uninstall any app plug-ins or enhancements from other manufacturers.

* If you recently updated the app or macOS, a plug-in or enhancement you installed may no longer be compatible.

* Diagnose problems on Mac to learn whether hardware you installed, such as additional memory, is incompatible, improperly installed, or defective.
