I finally managed to upgrade to v4 during black friday specials. I have now a floating license of studio and FMZ. I use a pc ( with a GTX 1080) and a mac laptop and I intend to use maxwell on both. I also have a couple of cpu's at the office I can send network rendering to.
As I saw few reports of issues after installing maxwell 4 - I was wondering if there is any advice about installing the software for the first time ( I currently have v3 installed).
