So a couple of days ago I got afflicted by my iMac's newest virus which is to say that although no longer shuts down willy nilly.

0:09.1

It will occasionally decide to not play video and it will instead show a perfectly green screen.

0:18.2

I've never understood why this is I have never found anything I can kill or force quit or anything to kind of.

0:25.5

You know get the engine sputtering again if you will.

0:28.4

If you remember me for a second is it only DRM like iTunes video or is it any video no no no any video like stuff of taking with my GoPro for example.

0:36.3

I wonder if it's like the like the the impact decoder failing yeah because like if you're just seeing green it's like this is like a placeholder that's put that's put here and like the GPU is told to render something here right and it's but like it's just not doing it.

0:49.0

So like I would say you have a GPU issue in all likelihood but possibly this might be software maybe.

0:54.6

It could be the or I was also of the impression that it might be GPU issue and what will eventually happen is I'll be the first one to get a Mac Pro of three of us and that'll really screw everything up but anyway.

1:05.1

So I had wind about this on Twitter is one is off to do and somebody who I don't have in front of me said hey have you looked into audio plugins.

1:15.0

And so apparently some random stranger on the internet had said another random stranger on the internet had had a similar issue but when they removed some audio plugins it went away and so the only audio plugins I'm aware of that I had installed our sound flower which I was using to try to capture a live mute math concert that I couldn't figure out how to download using YouTube DL which we'll talk about later actually sound flowers a mask ahead it is a mess it's an absolute mess.

1:43.1

And and I also had the audio hijack what is it AC or something audio capture engine something like that yeah so I uninstalled AC and more importantly I uninstalled sound flower and I'm just trying to like.

1:56.1

Shotgun approach figure out if uninstalling any of these audio bits and bobs will fix my green screen issue.

2:02.0

I got to say tips iMac pro is having a weird issue that I don't know is whether it's software or not it seems like it probably is when she plays netflix video sometimes and sometimes logic is running because she's now a podcast editor and sometimes it isn't but logic is installed as far as I know there's no weird plugins or anything sometimes the video playback in Netflix in the web browser will basically run through the entire episode that she's watching.

2:32.0

In like a split second as if it has no time restrain so just flies through and all the frames at once and it's done instantly sometimes this problem has been fixed by quitting logic.

2:42.0

So it does seem like maybe it's using the sound subsystem as the timing device for the video playback and something is wrong with the sound subsystem but this and this applies whether you whether she's using the built-in audio or not.

2:56.8

When it's in this mode switching audio outputs does fix the problem for whatever she switches it to when she switches it back to the built-in headphone jack the problem resumes.

3:07.9

And sometimes it has happened without logic running so some things up and I have the exact same computer across the exact same room with many of the same things plugged in and I've never had that problem but I also I never watch Netflix in my browser so maybe there's something with browser video where it's doing something but I want to.

3:26.1

I watch YouTube sometimes and that that ever was a problem so I should try to Chrome instead of Safari.

3:30.6

Why would I do that?

3:32.2

To see if it's the browser but Chrome is gross.

3:35.2

It's watching video is it's going to be a video window.

3:38.3

I would just like the first thing I would try is a different browser.
