Hi Laird and Focusbug users! I'm trying to install the new firmware on my CineRT but I think I'm doing something wrong. I have followed the steps described on the video (I'm using a Mac) but it does not seem to work. Here is a screenshot of the error I'm getting:

I'm going to start watching the almost 3 hour tutorial that you uploaded at FPAW but if by any means you know a quick fix for it or we can have a quick chat to help throw some light into this, it would be greatly appreciated! Thanks!

I was able to revert the HS to legacy firmware, but the base will not accept the old FW.
