There is a delay between notification sound and notification banner for mail app in High Sierra. How can I fix this?
Whenever I receive a notification from mail, I hear the notification sound but the banner shows up 3-5 seconds later. There is a delay between the notification sound and notification banner. This problem is only specific to mail app. How can I fix it? I have tried restarting and some other standard/quick fixes but nothing helped. This issue also came up after I updated to High Sierra. I would appreciate any help!
Had the same issue on a 2017 27" iMac. Spoke to Apple support....(I have APPLE CARE)
They had me do 3 things:
Upgrade to the latest version of macOS High Sierra 10.13.4 (That alone did not fix it).
Reset the SMC (for my desktop machine, they had me shut down and unplug the machine for 15 seconds instead).
Reset the NVRAM.
I was plagued with this issue too since upgrading to High Sierra, here's how I fixed it:
- Close the Mail app;
- Go to Settings - Notifications - Mail;
- Select "None" for the alert type;
- Untick ALL of the other options for Mail notifications;
- Close Settings;
- Open Mail and hit send and receive;
- Close Mail;
- Go back to the notification settings for Mail and restore the previous settings (or whatever you want to use in there);
These steps got me rid of the annoying 5 second delay between the notification sound and the popup showing up, hope it works for you guys as well.
Simply resetting the NVRam solved the problem for me. (I'd add this as a comment to Michael's answer, but I lack the rep.)
