Does anyone know if it is possible to run applications built on top of Unreal Engine (version 5) on the Vision Pro?

I have an app on the app store that costs a few bucks. Also, some users have received a free beta version outside the app store (so they could help me with testing). One of those users now would like to review my app on the app store, but, naturally, he wouldn't want to buy it on the app store, since his free copy works fine. Is there a way for him to still write a review on the app store? Can I maybe generate a token/code so he could download the app from the app store for free, so that he can then write a review? Or is there any other way? Best regards, Gabriel

I haven't tried screensavers in a while. Now, under macOS 11.6, it appears that screensavers don't stop when I press a key (any key, even Esc), or move the mouse. This happens with the built-in screensaver , such as "Flurry" and others. The only way to escape from screesavers seems to be a mouse click. I was wondering if this is intentional by macOS or if I screwed up the settings of my Mac. If it is intentional, I was wondering what is the rationale behind that change? (it used to be the case that screensavers would stop immediately when the user pressed a key or moved the mouse). If it's my settings on my Mac, which one could it be? Way earlier, under Catalina and before, it used to be the case that screensavers could receive keyboard events and act upon them. Did Apple bring that back? I am asking all this because I am developing a screensaver myself.
