macOS Update Required??

[polyphenol]

I've bitten the bullet and decided to get Apple TV for a month or two.

And Apple TV says I need to update macOS.

But I already have the latest release of macOS.

And explanations or ideas? I haven't used it yet - not even tried - just perplexed. Will try it later and see whether it works regardless.

I got the same message and ignored it. App worked fine for me and haven't gotten other than first time
