Thank you, but I don‘t know how I can possibly use the older installers without having newer software around. Could you expand on that?

I tried with macOS Big Sur and yes, the installer is one of those named „Install macOS Catalina.app“ or similar. At some point during the boot from the installer either a general error appears, or again one of those messages that the installed macOS version is too old.

Thank you, but I forgot to mention that even when creating an installer on an external device doesn't work. I don't remember the exact error message, but it may be again that the macOS version is too old, or another general error.

Thanks, it works. Now I only have to activate the bell for every thread I created.

This has been a problem for at least 1 whole year already. I don’t want to be rude, but I hope you’ve been looking into this for this whole time already (and yes, I filed a bug for this at the time, see https://developer.apple.com/forums/thread/669352).

I‘m confused now. Did it work 2 weeks ago and now it doesn’t work anymore? I never saw that bell, but if that was the answer to my problem, then why did everybody remain silent while I was complaining and waiting for a solution (that is, everybody except you)?

Do you see what I mean with „frustrating“? In 7 months no single update about this notification issue. I would think that this is one of the first things to fix in order to improve productivity, but apparently whoever decides what’s important and what’s not has another opinion, which remains undisclosed. The frustration comes from these two things: the timeframe and the silence.

It's possible that the automatic emails stop after 3 attempts, I didn't actually check if it's always the same feedbacks or different ones for which I get emails. I know that it would be best for you if we responded immediately to every feedback updated from your side, but I can tell you the same: it would be best if Apple responded immediately to every feedback I/we create and didn't let me/us wait for a response for years. If Apple can simply send automatic reminders about unanswered feedbacks while I/we cannot, it honestly feels like being bullied. If Apple wants to take their time to answer feedbacks (which currently means that some are never answered and is quite frustrating), then please give us our own time to respond as well, without being bothered by reminders that wander directly to the trash. I would be happy to keep receiving these emails if Apple showed some more effort in responding in the first place.

Thanks. I already filed a feedback for that. When you say "there is no great way", does that mean that there is at least some way?
