I guess I will be Etresoft now. I need to use my Developer account to upvote or downvote. And I need 100 points to do that. <sigh> Those 971 points in the other account aren't going to help.

Ability to edit posts. I see a partial solution to 8. Apparently, the "Edit profile" link in the profile popover is special. If you don't click "Edit profile", and instead click somewhere else in the pop-up, you can just view your profile and your recent posts will be listed. I don't know if there will be any indicator if any posts have new replies.

Fix numbering so that my "15." here doesn't get renumbered to "1." like the above reply did.

Has apple guaranteed to make sure all the questions and answers and discussions in this forum stay open to the public for as long as apple is a company?  No. In fact, this is the third iteration of the developer forums, that I know of. The entire content of both previous forums is now gone.

Might I be able to re-enable download from anywhere like on Catalina, so people in my own group can run binaries I might send securely (not via the App Store)? All of your other points were addressed above, but not this one. This is a distribution. You are now asking that other people disable their security for your convenience. How do they, or you for that matter, know that homebrew hasn't been compromised and you are now distributing malware? Because your security is disabled, it isn't possible for you to send anything securely. Just sign and notarize your software. Problem solved.

Is there no way to find threads you previously participated in, other than to bookmark them in your web browser or something? Nope. The only reference to my past activity seems to be on my profile... which only mentions the number of posts I made, but doesn't mention what or where they are or provide any way to find them. Yep. On the bright side (?), it is so difficult to find new threads in over 300 separate forums that you are very unlikely to actually participate in multiple forums. So just bookmark your favourite tags and go to those to see if there is any new activity in your threads.

No one, not even Apple, knows the future. Let's say this is true, and Big Sur allows overriding Gatekeeper. Then someone finds a security flaw in the override and the only solution is to remove it. So what do you do then? You specifically asked about prioritization. This has been a requirement for over a year. Do this now. If you haven't done a long list of crazy stuff, it takes 5 minutes. (Full disclosure - yes, I am well aware that you have done a very long list of crazy stuff indeed.)

I would expect one to be able to develop 'without restrictions' as long as nothing is signed for distribution. I can only assume the special permissions are linked to the signing certificate(?) You can. But if your app is configured for the Mac App Store, then it is going to run under that environment. There are some thing that you can configure yourself in the Developer portal to give your app local capabilities without App Review. But this is not one of them. You can always turn off the app sandbox. Your app will start up in a different environment, so you have to be aware of that. You'll have a different set of preferences and app state, for example. But this would allow you to test this one feature before it is approved. Approval for this entitlement is not guaranteed either.

Apple makes Swift and had no control over gfortran. You'll have to re-direct your requests to GNU and ask them to port gfortran to Apple Silicon.

Try adding timestamp to your options.

What are you trying to accomplish here? You can execute other apps from a sandboxed Mac app. But those apps will run in your app's sandbox. There is no guarantee that any other app will work properly. Furthermore, if that other app does something strange, like use a symlink, then you are going to be at the mercy of how well said app is implemented. Essentially, homebrew is not compatible with the sandbox. It is installed in one of the few system locations that is inaccessible without a sandbox escape. This isn't something that you can fix or that homebrew will fix. If you want to provide FFmpeg support in your sandboxed app, the best approach would be to provide your own FFmpeg installer on your website. You can't bundle it inside your app due to licensing issues. But you can provide a stand-alone version that will be compatible with your app.

The only thing I can tell you is that Apple provide a lot of value for that 30%. You get global tax/VAT collection and remittance. You get global compliance with all privacy laws. You get global compliance with certain consumer laws such as display of pricing. Apple handles all of the transactions, refunds, chargebacks, licensing, etc. Money shows up like magic and your accountant knows what to do with it. Otherwise, no one can give you any kind of pre-approval for your app. Apple certainly won't. Even if some one else tries, they don't know the details of your app and they have no control over Apple. Use IAP and a whole lot of problems magically go away.

@SceneStorage isn't supported on the Mac. And I know what you are going to ask next. No. I don't know when it will be supported, if ever.

The static keyword is usually used to define global objects or functions that are only visible in the file where they are defined. I'm not sure what the point of having that in a header would be. I suggest moving the function to an Objective-C file. Remove the static. In the header, use extern instead.

No. You can change your DockTile dynamically, while the app is running. So you could ship a regular icon, but show a rectangle version while running on Big Sur.
