Mac Os X Mail App Not Responding Average ratng: 4,4/5 6271 reviews

On more than a few occasions (read: a lot), I’ve had to help clients figure out why Apple Mail’s search function wasn’t working. It’s strange to be looking right at a message about baseball that doesn’t show up when you search for “baseball” within Mail. Kinda makes you want to punch things just a little bit.

If that starts happening to your Mac, there are a couple of ways to get it going again. First, you could force Spotlight to reindex your entire drive. While this method may take longer, if you’re not comfortable with finding and deleting files from your Library folder as I describe below, it may be the better way for you. For this, visit System Preferences> Spotlight, click on the 'Privacy' tab, and then either click the plus button at the bottom-left corner to add your entire Macintosh HD to the exclusions list or drag in the drive from your Desktop if it shows up there. You’ll see a scary warning when you do:

But after you click OK, you should see your drive appear in the list.

Mar 03, 2020  This scenario is best for when the Finder app on your Mac is not responding or becomes inaccessible. You’ll have to operate via Terminal command to delete the preference file to fix it. Here’s a step-by-step guide: 1. Open the Terminal app. You can either do a quick Spotlight search or find the app under Applications Utilities and open it.

Now you’ll want to select that drive and click the minus button to remove it. This’ll force Spotlight to start its indexing over again, and you can click on the Spotlight icon on the upper-right corner of your screen to see its progress.

Sigh. I’m gonna be waiting on that for a while. The things I do for you guys, I swear.

Secondly, you can try a more focused approach by making Mail reindex its database only. To do this, quit Mail if it’s running first. Then click on Finder’s Go menu and pick Go to Folder:

Sep 15, 2018  I'm suddenly getting Bing as my search engine on my Mac and I want Google. Technician's Assistant: What Operating System (OS) are you running on your Mac? High Sierra 10.13.6. Technician's Assistant: How long has this been going on with your Mac? What have you tried so far? A couple of days. I've tried to get rid of it!!! Nov 13, 2019  If you run Windows on your Mac using Boot Camp or Parallels, the problem might be with internet explorer or Microsoft edge. Make sure these have Google as a search engine option and make it your default. You can also delete Bing as a search engine option if you want. Once you set Google as the default, restart and check Safari. Dec 20, 2015  El Capitan issues all over the place: EL CAPITAN ISSUE 1: and and Safari search bar (using google) NOT working. I reverted back to El Capitan 10.11.0 (from 10.11.2) to check if there was a difference from before as I thought maybe updates were installed and broke my browsing experience. Google search app suddenly appear on mac os x.

Paste the following path into the box that'll appear and press Return:

  1. Jul 10, 2017  A Finder window should open with a folder named '' selected. If it does, move the selected folder— not just its contents— to the Trash. Relaunch Mail and test. Caution: If you change any of the contentsof the sandbox, but leave the folder itself in place, Mail may crash or not launch.
  2. Use information found in Mail in other apps. Delete emails. Print emails. Search for emails. Troubleshoot email problems in Mail on Mac. Problems sending messages. If you can’t send emails. If junk mail filters aren’t working. Problems viewing messages and mailboxes. If a mailbox is offline. If searching doesn’t find the.

Once the Finder window for that location opens up, delete any files in there that start with “Envelope Index.” As you’ll see below, I’ve got three:

After you delete those files, open Mail again. You may see this kinda-scary box, and if you do, click Continue and let it do its thing.

This step could take a while if you’ve got tons and tons of messages or if your machine isn’t the fastest, so be prepared.

Anyway, after whichever process you’ve chosen is complete, check to see if searching is working properly. Finally you can find all of those messages your grandpa sent you about everything that’s wrong with the world! Now don’t you feel better?

Having trouble using your Mail app on macOS Catalina?

It is very frustrating to not be able to send an important email simply because the Mail app is not working all out of a sudden. Many Mac users have recently increasingly reported this issue with no sight of a fix released from Apple to address it.

On the brighter note, this guide is written with tried and tested solutions which we were suggested from users, readers as well as massive amounts of research. The guide will discuss the reasons why your Mail app is not working correctly and the corresponding solutions for you to try are arranged according to the level of complexity of the issue from the easiest to the most tedious so that you can proceed to cross off the list one by one.

How to Fix Mail Not Working in macOS Catalina: 8 Ways

1. Check Internet Connection.

Here’s how to check the status of your Internet in macOS Catalina:

  1. First and foremost, quit any apps that are open and then connect to your Wi-Fi network.
  2. Next press and hold down on your Option (Alt) ⌥ key and then click to open Wireless Diagnostics from the Wi-Fi status menu . You will need to enter your administrator name and password when prompted.
Help! I don’t see the Wi-Fi Status Menu. How do I get it to show up?

If you don’t see the Wi-Fi status menu, then simply go into your Apple menu > System Preferences > Network > Wi-Fi. From there check the option to “Show Wi-Fi status in the menu bar“.

  1. Now the Wireless Diagnostics will begin analyzing your wireless environment.
  1. To diagnose whether the Wi-Fi problem is intermittent, then when prompted with the below screen, choose to Monitor my internet connection. This helps in identifying if there are any hidden fallacies with your internet which may be the reason causing the Mail app to not work.
  1. Great! Once done, you can choose to see the summary of the diagnostics by clicking on the info button next to each item in the summary to see details about that item. Based on the take action on the recommendations and improve the aspects of suggested. If there are test errors, try to restart your modem or router and try the test again by going back to Step 1.

If you find that there are no issues with your internet connection but the Mail app was still able to not download it, then proceed to the next method.

2. Check Mail Authentication Logs.

It is also possible that you have authentication problems when you log in to the email server. This happens usually when you update the password of your email directly on the website. There is no way for the Mail app to know if you’ve changed the password from the website without throwing an authentication error.

However, if you haven’t made any changes, then it could be that the file which holds all your authentication data (username and passwords) may be corrupted. To fix this you need to update the data of your account that is configured in the Mail app.

For both of the situations discussed, the following steps will help patch up any authentication errors and subsequently help update the Mail app with the right credentials:

  1. Go ahead and launch your Mail app in your macOS Catalina.
  2. Then click the Window option in the main menu and click Connection Doctor option.
  3. Now if there are issues with the connections, click the Log Connection Activity option and try again. Click on Show Logs option to check issues details of the issues.
  1. Next, search for the Keychain Access app and launch it.
  2. Then type in @ symbol in the search bar and press enter.
  3. Click on the account to highlight and delete the password from your iCloud keychain by doing right-click and click on Delete.
  4. Go back to your Mail app, click on the Preferences option, and then Accounts.
  5. Now delete your email account and add it back again with the correct details.
  6. Finally, restart the computer and relaunch the Mail app.

Now that you have updated the data of your email account in the Mail app, you will be able to connect to the server with no issues. But if you are still not able to download your new emails from the server, proceed to the next method.

3. Disable or Uninstall Any Third-Party Security Software.

There is a chance that your anti-virus software or firewall application on your Mac is not allowing you to download the email files to your computer. Some third-party security software does not have that configured by default. To be sure, disable (or uninstall) all unnecessary antivirus software and try to download your email again.

Once you’ve done that, you will be able to download your email files successfully. This solution has proven to have worked for a couple of users who managed to get their Mail app working after disabling their antivirus software on their Mac.

If the issue with the Mail app is fixed and you’re deciding to re-enable back the antivirus software, then make sure to contact their technical support beforehand and explain the situation. You will need to ask for their assistance on how to configure the software so it will not block the email download process responsible for the Mail app.
