Building on Catalina with Xojo 2019 1.1

I haven’t updated my license which expired in July.
But when I try to build my app again today, I get this message:

The default interactive shell is now zsh. To update your account to use zsh, please run `chsh -s /bin/zsh`.

I think you are building a 32 bit app. For 64 bit apps, the path name will include OS X 64 bit but yours says Mac OS X (Intel) which is 32 bit.

Catalina doesn’t support 32 bit apps.

Does this mean I can’t debug my app on catalina?
i.e. it’s 64 bit…

You can’t debug or run any 32-bit app on Catalina.

All modern Macs (as far back as I can remember anyway) can run 64-bit apps, I’d say go ahead and do whatever you need to update your app to 64-bit. If you’re lucky, it might just be a matter of recompiling.

So. No. I can not debug 64 bit apps on catalina with 2019 r1.1

Why do you say you can’t debug 64bit apps on Catalina with 2019r1.1?

You can’t debug 32bit apps… but 64bit apps should be fine, as that is the new standard.

Brian, from what you posted, you are building a 32 bit app, not a 64 bit one.

You set this on Build Settings / macOS / Build / Architecture : switch from x86 32 bit to x86 64 bit.

Assuming you were accidentally building 32 bits all along, you should also check out

Note: I think you can’t build a macOS 64 bit app from Windows, but I assume that’s not what you are doing, is it?
