Notifications Preferences not Sticking

Thanks, this worked for me.

The solution documented here worked for me too.

MacBook Pro (Retina, Mid 2012) running 10.10.

I do not restart often so I thought I was going nuts each time Notification settings went back to default.

I wonder if this affects all 10.10 systems but nobody changes the notification center settings, folks just don't restart, or if there is something about my settings previously that brought out this bug? Seems like kind of a big bug if it is impacting all installs of Yosemite considering the number and frequency of notifications with the default settings.

It only seems to happen in Yosemite upgrades, specially user accounts that were around pre-yosemite. If you create a new user account in Yosemite, the issue doesn't show up.

I wonder this with a lot of widespread issues. I think the majority of users just say, uh, that's weird, and couldn't be bothered. Then on one like this that happens after a restart, you're right, many probably never do; just sleep their systems.

I'm still not clear on the issue precisely. Mine is just that the order of the widgets doesn't persist across restarts.

Update 10.10.1 fixed this issue for me, without requiring terminal commands.
