Provide macOS binaries (was: "exec format error" when trying to execute binary from "releases")

[4kelly]

OSX Big Sur

1. Downloaded: md2blog-x86_64-unknown-linux-gnu.zip
2. Extracted ZIP

➜  ~ chmod 777 ~/Downloads/md2blog
➜  ~ cd ~/Downloads 
➜  Downloads ./md2blog
zsh: exec format error: ./md2blog
➜  Downloads bash md2blog
md2blog: md2blog: cannot execute binary file

Im probably just doing something wrong, but the Deno install worked fine.

It sounds like the issue is that I didn't provide OS X binaries (only Windows and Linux). Deno supports building x64/ARM binaries for Mac, but I have no way of testing them, so I didn't upload them. Maybe I'll just upload them and hope for the best :)

Happy to test one out for you. Lmk.

Ok, I updated the release page with macOS binaries. Theoretically they should work the same as "deno install", modulo Deno bugs :)

Thanks for all your help!

Tested and running using the new md2blog-x86_64-apple-darwin.zip.

However, on OSX you have to explicitly "allow" binaries downloaded through Safari via System Preferences Security & Privacy menu.

Users will probably receive this prompt. I'm not familiar with ways to mitigate this.

Then in settings:

Yes, this is a Deno limitation: denoland/deno#11154

Note to self: I need to update the documentation (after which this can be closed):

• List supported platforms (with caveat that macOS isn't tested)
• Warn about this error on macOS

[jaredkrinke]

macOS binaries are now produced by the build script (and I uploaded them for the initial release) and macOS support is documented here:
