get rid of no backups for x days notification

Hi there, mri1397!
Thanks for reaching out to the Apple Support Communities! It sounds like you are having an issue removing the notification about your Time Machine backup. The good news there are a few options you have get this situation taken care of. First, to just remove the alert, go to System Preferences > Time Machine and uncheck the option to “Show Time machine in the menu bar”.
A second option is to make the backup, which will remove the alert. This help article can assist you with the steps: How to use Time Machine to back up or restore your Mac. If you have issues making a backup, please check this help article: If you can't back up or restore your Mac using Time Machine
A third option is to simply turn off Time Machine. Then it will no longer ask about backups nor provide alerts if a backup hasn't been completed.
Take care!

Hi, I had this problem too since the update to High Sierra.

This worked for me:

Turn off all time machine options (obviously). Then not so obviously, right click the disk icon above Select Disk, then Stop using xxx for this backup. Confirm and hopefully you'll not have a disk or location for Time Machine to backup to.

Worked for me 🙂

Thanks Apple for not putting this option in the notifications center at the very least.

I solved this for my Mac running high sierra version 10.13.3 as follows:

open system preferences >> time machine - Uncheck backup automatically

The daily nag stopped and I still can perform a backup whenever I want

Others seemed to have disabled the ability to perform backups manually/automatically in their solutions

Send Apple feedback. They won't answer, but at least will know there is a problem or a suggestion for change. If enough people send feedback, it may get the problem/suggested change solved sooner.

Have you tried going to System Preferences/Time Machine and removing the backup drives?

I have Time Machine turned off and do not have the box checked to show it in the menu bar, but still get notifications that I haven't backed up to Time Machine in Xxxx days. I haven't used Time Machine since before 2014, and until moving to High Sierra, this was not an issue.

I upgraded to High Sierra, Time Machine is off, and I am getting this notification constantly. How do I turn it off? Thank you.

I hadn't ever made a backup. So I just went into the settings and removed backup drives... hopefully that'll fix the issue. Thanks.

I followed your suggestion and submitted feedback. I also mentioned that the required "Which operating system are you using?" drop down menu on the feedback page does not list 10.13.3, which I am currently running. It only goes up to 10.13.2.

I have the same issue; it's really very annoying.

🙂 That did it!

This definitely works!

Hopefully, something will get fixed.
