apple tv will not connect to my iMac anymore???

Thanks for the reply. I looked over those links and as I said in my original, none of the help files have worked, although I DID go through them all and during the implementing of them I noticed something that is a little odd to me and maybe you could tell me why this particular thing works, but not the Home Share? I had remembered about the mirroring capabilities of the iOS and just decided to test that out as well, and for some odd reason that works but the Home Sharing does not? Doesn't it's ability to connect for Mirroring indicate that the Apple TV and the iMac knows that each of them are there and has a wireless connection? None of those links pointed me to anything that I hadn't already done. Very sorry but, I don't have the memory of all the help files locations that I have gone through/applied since I began this troubleshooting, so I couldn't list everything. Are there any other helpful comments/suggestions that you would be willing to share? I'll gladly accept them/appply them.

Thanks

Yes, I have iTunes setup on my windows 8.1 system as well and I can see my iMac's Library with no problem. Just in case you're wondering, I do not use both libraries at the same time and when I'm trying to connect to the Apple TV the itunes program is always UNLOADED (not running) on the windows machine and I'm using the iMac iTunes combo. I'm always thinking that that could get a little flakey if I had them loaded up on both machines at the same time, so I don't do it. So I'm seeing shared libraries between the 2 computers with no problems. It's just that darn Apple TV/iMac combo that's giving me trouble.

Do you think I should try the windows/Apple tv combo and see it it works? I've never tried it before, always the iMac.

Well, I tried it while I was away for a bit and it CAN see the windows 8.1 computer, but I cannot see any of the videos, only music. Thant's a bit strange don't you think? I've got at least two of my movies on the windows system in itunes and I cannot see them at all.

Oh and I went back to see if it would see both of them and it still doesn't see the iMac computer.

Usually the other way around....cannot get anything done via windows computer but has always been very easy on the iMac, at least prior to updating iOS software that is.

The wifi is operating ok, in that I can d/l stuff from Apple like another movie...etc., it just don't want to work with Home Share. Could it still be a wifi problem (I chose not to run that Diagnostic based on the fact that I had connection to Apple..etc)

Yes I have McAfee installed on my iMac, but I have it set to allow all connections, so that should be hurting anything. No other type of security software accept the onboard security of the Mac itself (within the mac settings). I forgot about the movies you asked for, I'll check that and get back to ya.

Ok, I went back to check on the videos on the pc and it must have been a glitch that showed me the movies and they actually wasn't there, because after going back to check it they were gone. Ultimately I would like to be able to communicate between the imac and Apple TV, for the moment I would settle for the easiest way to get the video(s) from my imac to my pc 🙂 I've been dying to watch the purchased ones that I have already on the big screen in the living room. Thank you for all your help, I'm still open to any suggestions that you may have for me in regards to the problem between the imac and the apple tv.

Thanks

Yes, they do. The only thing I had trouble with was the video showing up and then dissapeared. But I just figured out why that happened. It was showing me that those 2 videos were in the cloud (purchased ones) and this was prior to new terms I had to accept and after accepting them I somehow got logged out of itunes. I logged back in to take care of it. Now theyre showing up in cloud again on my pc. But yes, I'm able to see both itunes libraries from both the imac and pc.

In the process of d/l'ing those 2 movies from the cloud as I type this out.

I was away for a little while getting something to eat....sorry for the delat in getting back to you. I cannot seem to get the videos d/l'd successfully onto my pc. So at the present time, I cannot see any videos listed except as being in the cloud. Tried d/l'ing one earlier but I can't find it nor do I have it listed in the pc library .. again except via cloud. ????

Well, yes I know that ordinarily on the Apple TV you would be able to display stuff that apple generally keeps in the cloud for its users...ie..some types of purchases and in this case videos, but I cannot for the life of me get those to list out on the apple tv even though I am logged into iCloud on it. It's as if my account doesn't exist, in some respects such as videos purchased by me, home sharing...etc. But I can d/l new videos under the same account, just not list out/or view ones that I've already purchased.

Yes, I've seen the listings of my pc library (music) and streamed it. And during this here reply I've been attmepting to get a video d/l'd from iCloud again, and it successfully d/l'd. Went back into the living room and I can now see the video listed on the apple tv from my pc. So now, it seems all is well between my pc and apple tv, but still cannot get anything related to the iMac and the apple tv going. Yes to your last question up there, I can see the pc's library now including the 1 video that I d/l'd from iCloud onto it via iTunes. I think I got to all you questions up there....please let me know if you want/need anything else to troubleshoot this.

Thanks
