I don’t know what to tell you. I’m on 10.10.2 and I’ve never had a problem. 
I just downloaded it from the ftp area and put it in my Dropbox, where you can download it from. [1]

I downloaded Squeak4.5-13680.zip from ftp.squeak.org and attempted to unzip it, got an error: Unable to expand “ Squeak4.5-13680.zip” into “SqC4.5Release”. (Error 2 - No such file or directory.)


The directory exists, and is in fact where the zip lives.

I’ve set System Preferences/Security & Privacy/General to Allow apps downloaded from anywhere

Does anyone know how to get past this error and unzip on Mac?
