It doesn't work.
Tried reinstalling it after uninstalling (2 times), rebooting the Mac, nothing.
What's happening? Running Yosemite.
Go to downloads and get the support tools. They have a specific download for fusa reset. I think by using this file you should be able to initaite an update plus Database reset. If that does not work please let me know.
How did you end up solving this?
I am having the same issue as you did - cannot get SAFE to update itself on my iMac.
Great if you can reply
