However, I note that the latest Mac snapshot is unsigned – has it always been this way? The installer displays the lock, but I have to option-click on the package to actually get it running.

Hi Tom,

I just checked, it is signed.  Here’s the SHA-1 hash on my end:


But, it is not downloaded from the App store.  Check your "System
preferences" > "Security and privacy" > "General" page.  If you have

Well, code signing is meant to allow you to ensure that the toolchain

To double-check, you can use the SHA-1 hash I pasted above.
