macOS High Sierra Notification Center auto closing or not opening at all I had a problem before about my icons not displaying correctly, and I followed Orlando Castro's answer in this discussion at Apple Forums.


  In Menu > Go (press option) > Library > Preferences
  Find and remove "com.apple.dock.extra.plist" and "com.apple.dock.plist" then restart.


After doing so I had no issue at all, but yesterday night I wanted to switch off "Night mode" which is located in Notification Center and for my surprise it didn't open at first with the gesture (Swipe left with 2 fingers from the right edge of trackpad), to make things worse I found that clicking on the Notification Center icon at the top right corner didn't make the Notification Center to be shown so I kept clicking on it for many times until it finally popped but it auto closed before I could turn night shift off.

Here's a video showing the issue: https://youtu.be/rU_Ph57dm8Y

I restarted my Mac and I'm still having this issue.

These are my Mac specs:


MacBook Pro (13", 2016, four Thunderbolt 3 ports) (With Touch Bar)
Processor: 2.9 GHz Intel Core i5
Memory: 8 GB 2133 MHz LPDDR3
macOS High Sierra 10.13.2


From the suggested questions while writing this question I found this other question: How do I re-enable Notification Center in Yosemite or El Capitan post-upgrade? which I thought could be the answer, but after running both commands:


launchctl load -w /System/Library/LaunchAgents/com.apple.notificationcenterui.plist
killall NotificationCenter



and restarting my Mac, the problem shown in the video above persists.

Also, in the suggested questions I found this other question: Can I speed up the auto-dismissal of Notification Center banners? because I thought it could be a problem related to the time it was too low, I switched it to 5 seconds, logged out and in after doing so, restarted my Mac and still no success.

As shown in the video, I can't get Notification Center to be shown while using gesture and sometimes I can do it while clicking Notification Center.

How to solve this issue?
I was working with a chatbot with Dialogflow which wasn't responding correctly. Once I did 2 restarts and correct it, my notification bar is working again as expected.
