Keyboard layouts on Mac config are just plain wrong (they all have this "§" character to the left of "1")

One of them is ISO and tge other one is ANSI. The ISO has a key between the left Shift and the Z.

It looks like your mac is not detecting the external keyboard correctly.

I am not familiar with that keyboard assistant but it looks like you did everything right. There are people here who are far more knowledgeable about language and localization issues and expect that they may assist.

On the Apple Brazilian layout, you can also type tilded characters via Option n, then the base letter .

This page has some ideas for trying to make your machine recognize your keyboard as the correct ANSI instead of ISO.

Is that picture of your actual keyboard? It is for Windows I guess and a bit strange, as it has the Enter key shape of ISO keyboards but is missing the extra key next to Z which ISO should have.

In addition to dead keys like Option-n, Option-e, etc for typing accented characters, you can press Command-Control-space to open the character viewer. There you can select all sorts of characters like accented, Greek, emoji, etc. This may help as a workaround in the present case, and is also of independent interest.

No, that's not my actual keyboard. Mine would be a Logitech K380, which doesn't have a key between Shift and Z

You can't go by that. Here is a picture of the Logitech K380. I'm guessing your keyboard is different. Keyboards are localized for individual markets. And with the modern internet, your keyboard could be for anywhere. If you want to have the layout match your keyboard, you'll have to pick the appropriate keyboard layout. For 3rd party keyboards, there may not be any appropriate layout.

I think Tom's site may have some utilities or instructions for creating your own keyboard layout. Or maybe the keyboard comes with something.

Probably it looks like this one instead, which should work just fine with Apple's US or Brazilian input source if the machine will only correctly recognize it is ANSI instead of ISO type.

Maybe there are some other configuration issues.

I realize the OP specifically mentioned a Brazilian keyboard, but does that mean the computer and keyboard are correctly configured for Brazil?

When I check that site and hack in Brazil, I get a keyboard that looks very similar to a US keyboard. But then I remembered that Brazil could be one of those countries (like Switzerland) where Apple sometimes makes language assumptions. When I search the Logitech site for a Portuguese version, there's no result. I guess Portugal doesn't rate. There is an "other EU" site with a keyboard that looks like what the OP is describing.

So that lead me to want to ask:

1) Where is the OP, specifically?

2) Where was the keyboard purchased, specifically?

3) How is the system configured in localization settings?

Of course, the OP is likely using Ventura, which could simply be wrong. On Monterey, none of the Portuguese keyboard looks like what the OP is describing. But then, I didn't change any of my region or language settings.

Even in Ventura, it should be possible to override the system setting. Shouldn't it?

He's not using any of the layouts called "Portuguese," but instead the one called "Brazilian," as shown in the link he provided that shows his input sources. This layout is the same as US except for having accent dead keys at the top left corner and the key next to return which make it especially easy to type accented characters

Portuguese is the official and most popular language of Brazil.

I just checked in Ventura and it is more or less identical to Monterey. There are 4 different Portuguese keyboards, 3 of which are Brazilian. None of them look like what the OP describes. Therefore, my guess that there is some other system configuration factor affecting the layout is probably correct.

Every keyboard layout has 3 forms: ANSI, ISO, and JIS. The OS is supposed to determine which form of hardware keyboard is attached and use the right layout for that. Sometimes it fails. The "Brazilian" layout in its ANSI form matches the poster's hardware keyboard, but the OS mistakenly thought the hardware was ISO and used that form instead. The poster has now been able to get the OS to recognize the hardware correctly and all is well.
