On the Mac you need to right click the file, so it downloads without uncompressing it. The Maslow needs a compressed file so it will fit in the allocated space. I don’t have a Mac, but looking at the **Updating System, now index.html.gz** above describes the procedure you need to follow for the Mac.  
As I understand it, it doesn’t compress it properly if you uncompress and then recompress.

> When you just do a standard download to the download folder it removes the .gz  
> If you right click(two fingers click) it and choose “download linked file as” you can choose the location and it will keep the extensions.
