Installing 2.21 - Newbie Question in Helix Posted May 12, 2017 I'll apologize ahead of time, because this has probably already been asked. Ive been searching for about an hour and cannot find anything. I just bought a Helix floor unit in the last couple of months and it has firmware version 2.01.0 installed on it. I have not installed any software on my computer. Reading the 2.21release notes is confusing because of this. Seems like I need to download software on my mac first in order to back up the Helix. Is this correct, and what is it called/version, etc.? Once I do this I can back-up and follow the release notes. Is this correct? Thanks so much!
