Thanks for the report, @ksank1976!

Please could you confirm this was from brew install binaries?

You could try building from source. Others have had success that way as a workaround. If you do try that, please could you report back on whether that works for you? Thanks, and sorry for the friction.

Thanks Bob!! Finally managed to install with the OSX disk image for El Captain. You can download the installer from the link below. Thanks for your response.

No problem. I'm just going to reopen the issue, because until the Homebrew binaries "just work", we still have work to do! Glad you are unblocked though.

Hello,

Mix installed from homebrew (1.0.1) does start properly => No problem. I just built Mix from source today (webthree-umbrella.git:develop) and I run into the same issue reported in this ticket on OSX El Capitan 10.11.4

Thanks for the update, @chevdor.

That difference you are seeing between homebrew and build-from-source is very interesting and good to know.

The funny thing is that the fact that the mix within homebrew is 1.0.1 is itself a bug :-)
