Nothing on this computer. The only thing is the AVHD Prefs window pops up randomly as I mentioned in this thread
Otherwise as I said my son called that he couldn't login. And I actually have the PIN number on my iPhone Notes app if I'm not home and there is an issue. So he called and got error regarding PIN trying to access this computer that is up 24/7 and he and my other son use daily from where they live. And I've been using Air Video now for has to be 4 years.
And the new PIN since installing AVHD and buying the new App. What is that, just over a year or so? So I then Opened AVHD Prefs on the iMac to tell him and yup different PIN. I compare it to the original in my Notes app - different. Changed all by itself. No AVHD crashes, no software updates to iMac, no iMac crashes - the most stable computer. Running 10.9.1 (13B42).
And as I mentioned in the thread, the AVHD prefs window pops up randomly on my MacBook Pro too. Did it this morning. And that computer is not used other than internally with AVHD by me sometimes.
But I can assure you - the PIN changed all by itself on the iMac.
