A dvd that will no longer play.

I tried this, but still a black screen comes up. The title of the dvd is at the top of the screen, but that's all.

But maybe I didn't do everything correctly. What does "with no peripherals att he'd" mean?

Thanks, BDAqua, for all the advice. I couldn't find the location that you suggested; if you can give me any more hints as to where it may be, that would be great. Otherwise, I'll just have to live with it.

Now, however, I have a new and bigger challenge. When I turn on my computer, the DVD player screen automatically opens up, the pinwheel starts turning, and continues doing so for several minutes. Any attempt to open up any other program is on hold until the twirling pinwheel stops. The same thing happens when I put a DVD into the player.

I don't know if this is related, but this latest glitch started after I upgraded to Catalina.

Any ideas?

Sorry, but what I said above still applies:

I tried resetting the SMC, but still have the problem. Are there any other possible solutions?

I found a file called com.apple.DVDPlayer.plist and trashed that. It didn't help. In my frustration, I also trashed a few other files that were created on about the same date (I can be pretty compulsive — and stupid — sometimes), then had second thoughts about them. So I didn't empty the trash until I had copied the trashed files onto an external hard drive, then unplugged the drive from my computer. The dvd player's performance didn't improve.

I have downloaded EtreCheck. How do you want me to proceed from here?

Thank you — and stay healthy!

I uninstalled the cleaning app, as you suggested, yet the external dvd player is still slow. You may have noticed in my report that the dvd player is only slow when my computer is not connected to the internet, which is frequently. This was something I just recently noticed.

Here is the report. I hope you can access it.

Wow! That worked! I'm amazed. But, if you don't mind taking the time, could you please explain to me what the problem was, why this solution worked, and where I should go from here? Should I switch to this new account and get rid of the old one? Or should I get rid of this new account once it has served its purpose?

Thank you so much!
