macOS 15.1 betas

Update

The latest macOS 15.1 beta is now being signed by Apple, so we've made it available in the app again.

Original Message

Please note that Apple is not signing macOS 15.1 betas for virtual machines, so those cannot be installed in VirtualBuddy or any other Virtualization-based app.

It's unclear if this was done on purpose or by accident, but my guess is that Apple is not supporting macOS 15.1 betas on virtual machines because those betas are only available to devices that support Apple Intelligence, and since virtual machines do not support it, there's no reason to make those beta versions available.

We have removed the macOS 15.1 betas previously listed in the downloadable builds within the app, macOS 15.0 betas are not affected.

Future versions of VirtualBuddy will be able to provide signing status upfront before the user has had to download and attempt to install a build.

I have filed FB14908914 with Apple reporting this issue and will update this post if I get a response.

I've managed to successfully install 15.1b3 (24B5035e), so it appears that Apple has resumed signing at least this release.

Thanks for letting me know, @lukele! I have verified that they're indeed signing it again, so I'll be closing this discussion after publishing the latest beta in the app.
