I agree, the instructions are sparse and the installation instructions are cryptic if you do not know what you’re doing. Yes it’s pretty intensive afaik. I have 16gbs of ram and 2,7ghz i7 and i’m experiencing the same fan blasting.
This is often the most frustrating about everything. I had a small euro system a couple of months back which I had to sell off because of $$$ so this software is a godsend.
