Apple TV 3rd Gen restore to original settings on MacBook Pro
I have an Apple TV 3rd Gen. I lost the remote and the remote app on my iPhone won't pair with it. I can't do anything on the Apple TV. I connected the Apple TV to my MacBook. I opened Finder and selected Apple TV. At first, it showed "Software: loading." It was stuck in this status for hours. I unplugged the AppleTV USB and plugged it back in. Then, it showed this:
I can select one of two Software options, either the tvOS 8.4.4 (as in above screenshot) or OS Build Version 12H885 as in the screenshot below:
I selected Restore Apple TV, and I got this pop-up:
I gather that the software on the Apple TV is out-of-date, but I can't update it because I lost the remote and I can't connect to the device. I had read in the discussion community that you could reset it by connecting it to your MacBook and then pairing it with the remote app.
Does anyone know how I can resolve the error in that pop-up screen?
Thank you.
