Slack not in Notification Preference list

This works for me:

1. Go to "Direct Message" --> your name
2. Type "/remind me" and Enter
3. You'll see a notification pop-up
4. Now Slack show up in System Preferences --> Notification

I GOT IT WORKING! Okay, it might be just me, but here is how I got it:

Open slack, go to Slack > preferences > Notifications and click on 'All new messages'; then scroll down and also select 'show a badge'.

Then ask someone to send you a direct message, and click off their name. Then when they message you, a big notification comes through on the top right, click on it and it'll open up Apple's notification center, and selects Slack (which did not even exist in the list before!). Now you can control the notifications. You can now go back to slack, and tell it not to notify you for everything, the red dot still works.

Let me know if this works for others :)

Following these steps as suggested by slack support team resolved my issue,

As a next step, I'd like to see if restarting the Notification Centre via the Activity Monitor fixes the issue for you. You can do this by following the below steps:

1. Open up Activity Monitor
2. Type Notification in the top right search bar Select Notification Center and then click on the stop sign shaped button near the top left corner to kill the process.
3. Wait 10 seconds and then start Slack up again. The new Notification Centre process should behave as expected.

This is what solved it for me, I opened slack in browser, also had Slack downloaded on the Desktop, from the browser I went to my name and hit /remind me, which brought up the notification in the Desktop app, also following this I could see it appear in the Notifications of System Preferences. Day saver !

mainul89,

Thanks for getting back to us. Let's check in a different user on your Mac to isolate things a bit more. Set up users, guests, and groups on Mac will walk you through creating one if needed.

Does the Slack application appear in System Preferences > Notifications here?

If not, have you had a chance to reinstall the app as well?

If these steps don't help, then we'd recommend getting in contact with the app developer to report this.

Thanks.

Could you please clarify where you changed the Do Not Disturb notification setting? If you are referring to macOS Notifications, all of my Do Not Disturb settings have already been disabled (unchecked). So that's not the issue or resolution. Thanks.

Hello mainul89,

Thank you for taking the time to post your question using Apple Support Communities. We understand that Slack is not appear in your Notifications System Preferences so that you're able to manage those, and we're happy to assist.

You mentioned that you're running macOS Big Sur. Have you checked to ensure that you're updated to the latest version? How to update the software on your Mac

Also, is the Slack app completely up-to-date? Update the Slack desktop app

If you find you need to install any updates for the Mac or app, we'd recommend restarting, then checking to see if you're able to manage notification settings for the app in System Preferences.

Be sure to check out this guide for Slack notifications as well. Guide to Slack notifications

Let us know if this helps.

Regards.

P.S. I also reached out to Slack support as well. They in essence suggested the same steps to resolution but then referred me to Apple Support for help to fix (which is why I'm here). SMH. Though in their defense, in a followup response from them, they did indicate that they are working with Apple to fix.

I was having this same issue with not receiving any Slack notifications and not having Slack in my System Preferences>Notifications, but I just found my solution and thought I'd share in case you are still having the issue. I also have the most updated OS and Slack.

It was a silly fix, but I didn't know I had "Do Not Disturb" mode set as "Always On". Once I deactivated it, I received a Slack notification, and Slack has now appeared in my System Preferences>Notifications.

Hope this helps!

I have the same problem. I just erased my iMac Pro and did a clean install of Big Sur 11.4, installed the Slack ver. 4.17.0 desktop app and it's not listed in the Mac notifications system preference. Previously I was running Big Sur 11.4 which had been upgraded from Catalina and Slack had been running on Catalina. The upgraded Big Sur 11.4 showed Slack in system prefs>notifications.

Somehow it appears a new installation of Slack on a new, non-upgraded version of Big Sur does not have a notifications entry in system preferences.

I'm having the same exact issue except I upgraded my Mac from Sierra and then had an issue and Apple Support Reinstalled BigSur from Scratch but then I Restored from my Time Machine Backup.

MacOS Big Sur 11.4 with Up-to-date Slack and Slack is not present in the notifications center.

Not set to do not disturb and all Slack settings set to notify.

Make sure to set up "Do Not Disturb" hours. In my case doesn't work the notifications because when I updated to Big Sur, it was checked "from 0:00 to 0:00" default, so I uncheck "From" hours options.

System preferences > Notifications > Do Not Disturb

The same for me - both macOs and Slack are up to date, and it's not a part of notifications list. System restart, slack reinstall didn't help.

I, too, am having the same problem. I have uninstalled and reinstalled slack.
