This guide will walk you through all the steps you must take to resolve pretty much every issue with the Mac Mail app not working Today, yesterday. Let’s dive in.

How to check you have the latest update installed:

1. Select the Apple menu, top left, and select About This Mac.
2. Select Software Update to find out if you need a quick update.
3. If, like me, you do, press Upgrade Now.

Test again, if Mail is still not opening on your Mac, it’s time to move to the next tip.

Solution # 3 Repair the Mac’s keychain and rebuild your mailbox.

This guide for transferring your Mail to a new Mac includes instructions for these procedures, which can help with forgotten passwords, incorrect message counts, and messages that don’t display. It can help move your email, too, should you ever need to do so.

Solution # 4 Reset the Mail app

1. Open Setapp and type “CleanMyMacX” or “declutter Mac” in the search bar
2. Find CleanMyMac X in the search results and click Install
3. Once the app is installed, open it, click Uninstaller in the sidebar
4. Select Mail from the list of apps and click on the arrow
5. Then select the Mail’s supporting files, logs, etc. This will reveal the arrows with the text “Your selection” next to the Mail icon in CleanMyMac X. Select “Reset”
6. Finally, click the Reset button.

Solution # 5 Restart in Safe Mode

Another thing you can try is to restart your Mac in Safe Mode and try to use the Mailbox search again. There are two ways to enter Safe Mode on a Mac, depending on whether it’s an Intel-based model or an M1 model:

Solution # 6 Shift-launch Mail

Restart your Mac, go to your Applications folder, hold-down Shift, and open the Mail app. Now exit the app, wait for several seconds, and Shift-launch it again. Next, restart your Mac one more time and launch the app normally. Shift-launching any app would make it “forget” its state when it was last used, hopefully fixing any minor bugs that may be causing the search to not function properly.

Solution # 7 Get iCloud Mail working on the Mac.

iCloud offers a selection of cloud-based services for macOS and iOS devices. These include syncing browser bookmarks and login credentials, along with an iCloud-based email system. Setup is easy.
