Notification settings aren't being retained
After upgrading an iMac and MacBook Air from Mavericks to Yosemite, changes to Notifications aren't being retained:
- Looking at the Notifications Preference Pane - there are a set of apps with Notification settings.
- Changing Notification settings for any of these apps works - ie I can change the alert style, whether notifications appear in Notification Center, etc.
- These settings are respected until I reboot / logout, at which point they revert back the original settings.
- New apps will appear in the preference pane when they are run. Notification settings can be changed. After rebooting, the app disappears from the notification preference pane until I run it again, at which point it appears with default settings.
So what seems to be happening is that these settings aren't being saved to disk. I have:
- repaired permissions
- deleted the
~/Library/Application Support/NotificationCenterfolder
None of this had made any difference. Does anyone know where these settings are stored?
Fixed:
This thread on the Apple forums is the key:
- Open the Library folder in your Home folder.
- In the Library folder, open the Application Support folder.
- Locate the folder named NotificationCenter. Drag this folder to the desktop.
- Next, open the Terminal application and enter the following
.
cd `getconf DARWIN_USER_DIR`
rm -rf com.apple.notificationcenter
killall usernoted; killall NotificationCenter
- Restart your computer.
The issue is clearly to do with the NotificationCenter database. There are 3 files:
- db
- db-shm
- db.wal
In my case db.wal was a 0 byte file compared with 1.9MB on a correctly working Yosemite install. Permissions were correctly set, but looks as if Yosemite wasn't writing to it. Only deleting db.wal didn't fix the problem - another 0 byte file was created on restart. Deleting everything works though!
