OS X Safari keeps forgetting cookies My Safari constantly keeps forgetting cookies, even during a session. I.e. I might log into this Stack Exchange, and a few minutes later I am logged out again (without even restarting Safari). This also affects other sites (e.g. Google).

However, when looking at "Manage Website Data..." in Safari's privacy settings, it looks like the cookies are there (although I'm not 100% sure about this).

Possibly related messages in Console.app:

I have already run "Repair Permissions", to no avail. I have also deleted all cookies and started from scratch, however Safari still forgets newly added cookies.

Also, until a few weeks ago, everything ran just fine. Installed extensions are NoMoreiTunes, Save to Pocket, Ghostery and SaveFrom.net helper.

Any ideas on what could be the culprit or something else I could try?

I am running Safari 10.0.1 on OS X 10.11.6 (although the issue already occurred with Safari 9).

Something you can attempt:


Enter Recovery mode (⌘ + R on startup)
Go to Utilities -> Terminal
Enter this command resetpassword and hit enter.
At the bottom of the window that appears, you will see "Reset Home Directory Permissions and ACLs". Click "Reset" and reboot.


This will hopefully resolve the permissions issue you're encountering, assuming it is rooted in a permissions issue- perhaps you manually migrated your user folder at some point?
