I think you are getting the Install from the PTS account not the normal (ex Beta) ESO account because there is a newer version/ type of installer from the normal Account Mac client link which is Install_ESO.zip;Ok this seems to have resolved itself when I downloaded a new Install_ESO.dmg.
They must have modified the patcher.

I just downloaded the install_ESO.zip, this installer says I have 48 GB free but in finder I have 95 GB free, I just copied a lot of stuff away to external hard drive (around 70 GB), so I do have the space available. Any suggestions?
"Just over" may not be enough. The computer needs around 15% to allow for overheads. Trying to install close to the limit can cause issues. And check the pst above regarding TimeMachine.i have a macbook air with just over 60G free, the client is still saying i need to free up 60G to get farther and its really got my irish up >:/
