The chances are that your Mail App is unable to save the prior state properly and that’s why it keeps crashing and or not responding.
Mail Not Launching after the macOS Mojave Upgrade
One easy thing to try if faced with Mail Not Launching on your MacBook is to run the Mail app from the Applications folder as opposed to the dock on your screen. If that works, you will need to clear the icon from the dock and then re-add it later.
If launching using the Applications folder did not resolve your issue, please follow the detailed steps below.
Mail Crashing or Slow After macOS Mojave Upgrade, How-To Fix
To resolve the mail crashing/mail not responding issues on macOS Mojave, the best course of action is to remove some of the prior app state data, restart your MacBook and then re-launch Mail. We recommend that you have a clean backup of your MacBook before proceeding with the steps.
- Start with force quitting the Mail App on your MacBook / Mac. If you are unable to force-quit the app using the dock icon ( Mail App does not respond), open the activity monitor.
- Click on the Spotlight icon at the top right corner of your MacBook and type in Activity Monitor (image). Click on the Activity Monitor App to launch the utility.
- Type in ‘Mail’ in the search box and then highlight the app. Next click on ‘X’ to shut down the application.
- Now that the App has been closed, we will start with clearing some of the prior-state files on your MacBook.
- Open Finder App
- Hold the Option key and Select Library from the top menu
- Go to the folder ‘Containers > com.apple.mail > Data > Library > Saved Application State‘ and move the folder called ‘com.apple.mail.savedState‘ to the trash.
- The next step is to clear the Mail app library containers
- Open Finder App, Press down the Option Key and click ‘Go’ on the top menu and choose ~/Library/Containers
- Look for the following two files and drag them out to your Desktop. That way you will have the files saved for later if you need them.
- Next step is to remove the Mail Envelope files from the Library. You will do this using Finder App as explained above. There are three main envelope files, and they are shown in the image here.
- Empty your Trash, Restart your MacBook and then try launching Mail. Check if your Mail issue has resolved.
- If your Mail launches without any issues and does not crash or hang, you can move the com.apple* files from your desktop to the trash
Depending on how you set-up your Mail App, your preferences for Mail might look different as they set back to default.
Mail Folders Missing After macOS Mojave Update
The other issue that sometimes happens when you upgrade to a new macOS version is that some of your Mail folders vanish. This situation is rare, and we haven’t seen it while using macOS Mojave.
The first thing to do if you have this issue is to check your Mail Connections on macOS Mojave
- Launch Mail App
- Go toWindow on the top menu and choose Connection Doctor
- This will show you if there are issues with the Mail Account connections.
- You will need to re-check your Account settings or delete and re-add your email account into Mail to get this resolved
- Once the connection issue is resolved, the chances are that your Mailbox will be accessible
If your connections are good and you are still missing your folders, you will need to rebuild your Mailbox and Re-index your messages to resolve the problem. The Apple support documents walk you through the rebuilding effort in great detail.
