Plex Web App is preventing Mac OSX Screen Saver & Display Sleep from working

Hi there,

Apologies for newbie error - I am re-posting this here as I think it originally posted this in the wrong area. Additionally the original post has a status of “Answered”, but there are no comments/replies attached to it. Therefore I am unable to “accept/reject answers” as the popup keeps requesting if there are none. Or am i missing something fundamental here?

I am running the following on an iMac with 24GB RAM, OSX El Capitan 10.11.6

Plex Media Server 1.0.2.2413
Plex Web App 2.7.6
Remote Access is not enabled

I connect to Plex mainly using Apple TV4 (love the Plex App !), plus occasionally Plex on iOS on iPad Air or iPhone 6Plus. Have a Roku as well but rarely use it since Plex was released for AppleTV. I upgrade my Plex software quite frequently (am PlexPass member).

Sometime in past couple of weeks, I noticed that the Screen Saver and later Display Sleep no longer was kicking in on my iMac - which is normally running 24hr as a media server. I normally have Plex Web App permanently open in Google Chrome (Version 52.0.2743.82 (64-bit)) in a couple of window tabs - one for main page, one for status, one for settings. I have Sonarr running in Safari. This was never a problem until a few weeks ago.

By elimination I have narrowed it down to where having any Plex Web App window open (in either Chrome or Safari) is preventing the iMac Screen Saver or Display Sleep for kicking in. The Energy Saver setting on the iMac does not put the Computer to sleep, only the Display after 10 minutes. Wake on LAN is enabled.

I am unsure if this is a bug that has appeared in a recent release or whether there is a configuration issue here.

Would welcome any help in resolving this as obviously I don’t wish to have my display running all the time. Ideally I would like to get a suitable Mac Mini to run as a separate media server, but funds don’t currently permit.

Thanks for your help.
Cheers
Tim

PS - If a moderator could advise me how to delete the original post or change it status - that would be greatly appreciated.

Is there anybody working for Plex who can please help me on this one?
Is it only me or is it a bug?
Also - is there a Plex Moderator who can help fix my original post (earlier on July 22 - in Plex Web App forum) which has a status of “Answered” yet there are no comments posted against it. There’s an annoying message asking me to “Accept/Reject Answers” but how can I if no answers have been posted? Or am I being incredibly dumb here ^:)^

Many thanks in advance.
