<p>I'm trying to help someone many miles away install CogSpur on a
mac. I run Linux as a newb.</p>
<p>On the mac they have run:</p>
<p><br>
</p>
<pre><code>$ curl -L -o CogSpur.tgz <a class="moz-txt-link-freetext" href="https://github.com/OpenSmalltalk/opensmalltalk-vm/releases/download/201608171728/cog_macos32x86_squeak.cog.spur_201608171728.tar.gz">https://github.com/OpenSmalltalk/opensmalltalk-vm/releases/download/201608171728/cog_macos32x86_squeak.cog.spur_201608171728.tar.gz</a>
But when they try to unzip:
</code>
<code>$ tar -zxvf CogSpur.tgz
tar: Unrecognized archive format
tar: Error exit delayed from previous errors.
Thanks.
