I am getting the same server error:
On this note, can I ask that you (McNeel) include a direct link to Rhino - Download - Rhino for Mac WIP on the download page of Rhino. Right now you are first redirected to Welcome to Serengeti then from there you have to know to click on the link that takes you to Rhino 8 WIP Available Now!. From there you have to scroll to the very bottom, so that you can finally end up at Rhino - Download - Rhino for Mac WIP.
Why so complicated? Why not just link from Downloads straight to the page for the WIP? Or maybe you could just add a “Direct Link” to the download!?
