Chris,

Did you manage to update macOS to Beta 4? I see a notification, but downloading fails in several seconds.

Assuming it's the same as the Intel version - software update offers two versions: Full (12GB) and (click on More...) and you get Update (3GB). I chose update :)
o Lazarus v2.1.0 r63871, FPC v3.3.1 r47164, macOS 10.14.6 (with sup update), Xcode 11.3.1
o Lazarus v2.1.0 r61574, FPC v3.3.1 r42318, FreeBSD 12.1 amd64 (VMware Fusion VM)
o FPC 3.0.4, FreeBSD 12.2-STABLE r365646 amd64
o Lazarus v2.1.0 r61574, FPC v3.0.4, Ubuntu 20.04 (Parallels VM)

Igor,
 I believe if you look at the left panel of the Software Update window you will see the text "Updates for this Mac are managed externally". If you see this, I believe that the "Update Now" button (if displayed) will not be functional. You need to wait for the external management system to push an update for you.

Chris,

Thanks, I've understood.

trev,

I think it's a special case with this Apple DTK.

It seems that macOS Big Sur for Apple Silicon doesn't support OpenAl (or it's a bug in current Beta).

My OpenAl code doesn't play anything. I found OpenALSoundManager here on the forum:
https://forum.lazarus.freepascal.org/index.php?topic=37890.0
and that code also doesn't play anything. Just silence.

APP compiled for Intel in Rosetta 2 emaulation plays OpenAl audio.

If it didn't support OpenAL at all, you would get linker errors (or perhaps segmentation faults in case it's dynamically loaded, does not exist, and then you try to call its functions). It could also be a bug in the binding or in the way it links to/tries to load the framework.

Yes, it's logical.

I had to restore Apple DTK Mac and reinstall FPC and Lazarus from trunk.

I successfully compiled FPC trunk for AARCH64.

But Lazarus trunk cannot be compiled:

UPD. I downloaded old revision from July 31 which worked fine for macOS ARM. Now Lazarus compiles OK on Apple DTK.

There is a bug in one of recent changes in the code.

Be careful with updating Apple DTK from Beta 1 to Beta 4 or 5. It falls to infinite bootloop. There are many complaints on Apple forum.

I had to restore my Apple DTK in DFU mode using another Mac and USB-C cable to recover macOS and install Beta 4 from a scratch.

Updating from Beta 4 to Beta 5 worked fine.

Chris,

Can you check Beta 7 on Apple DTK?

I just updated from Beta 6 to Beta 7.

I could run earlier compiled ARM version of my app. After recompilation it crashes on startup.

Also since Beta 6 I can't load any dylibs which I compiled earlier on the same Mac (DTK).

It seems to work worse with each Beta.

The issue with your dylibs no longer working under beta 6 is probably because they added a requirement for all binaries (executables and dylibs) to be code signed in that version. When you link an exe/library, the linker will add a fake code signature (that will be trusted by you local system, but not usable for distribution). That signature will be invalidated if you perform any extra operations on the generated binary afterwards though, in particular using the strip tool. And while FPC uses the linker's symbol stripping functionality when generating executables, it uses the strip tool when generating dynamic libraries (I think this is because older versions of the linker stripped too many symbols away).

So it should work if you codesign your libraries again after stripping them, either using a fake signature (see the beta 6 release notes for the command) or using a real code signing certificate. I'll look into changing the compiler as well. I'll also look into beta 7 issues (I did get a DTK in the end about two weeks ago).

Edit: to disable stripping, compile with -Xs-. That should allow your dylibs to work again.
Edit 2: it's actually listed as a known bug that strip invalidates these signatures, so I'll wait with making changes to the compiler since that suggests Apple may still fix it

There are actually a bunch of threads on Apple's forums about issues with codesigning on beta 7, e.g. https://developer.apple.com/forums/thread/660812 . My DTK (fortunately, in hindsight) failed to update to beta 7.

Jonas,

I just restored Apple DTK to Beta 8 and I can't compile FPC again according wiki.
