This week, an updated Apple support article offers a reminder on what to do if Mac OS X Mail keeps crashing (“unexpectedly quitting” in Apple-speak). The most likely cause is a “damaged” or otherwise problematic message. In such a case, Mail will initially crash as soon as you select the message and attempt to display it.

Likewise, Apple has also issued updates for El Capitan users which you can get by opening the Mac App Store and clicking on the Updates button at the top of the screen. If you’re having problems with Office 2011 crashing in El Capitan, we also show you how to fix Office El Capitan problems in the 2011 version.
If you want to stop receiving text messages on your Mac, you can simply sign out. Open Messages, click Messages Preferences from the menu bar and select the iMessage tab. Next to your Apple ID at the top, click the Sign Out button. Having the ability to send text messages on Mac with a built-in app is truly convenient.

Unfortunately, this is only the beginning of your trouble. It gets worse. When you relaunch Mail, it will return to where you left off, again attempting to display the damaged email. Oops. The message will thus cause Mail to crash again, before you get a chance to do anything else. Can you say “endless loop”?

There is a way out of this. The first step is to hold down the Shift key when launching Mail. This forces Mail to open without displaying the crash-inducing message—or any message at all.

Hi, I have been using the message + app on the mac El Capitan for a while. It crashes and freezes all the time but mainly works. I got a new mac with high sierra on it version 10.13.4. Now message + just quits immediately after opening. I removed it, redownloaded and installed it from app store but. However, Outlook 2016 for Mac looks for a file that is named osfcore.framework and cannot find the file inside the app bundle. Workaround To work around this problem, rename the OsfCore.framework file as osfcore.framework.

Next, drag the horizontal divider in Mail’s window window so that you can no longer see the area for the display of messages. You can now make a selection in the left-hand column. Only the listing of message titles should display.

Finally, single-click on the message that was active when the crash occurred. Select to delete it. Assuming that the deleted email was the only one causing the crash, your problem should now be over.
