The installation no problem, I have a mac and Logic Pro, it's done alone.
I do not know the problems faced by machines that lack of power, but the top of my 6 gigabytes of RAM, either with or without a Logic it works perfectly.
The software is very easy to use, just choose between the different amplifiers, cabinets, stompboxes and rack.
That's great

SUITABILITY/PERFORMANCE

A PowerMac 2x2, 7GHz with 6 gigabytes of RAM, again I had no problem with respect to the records in Logic, it just happens, and exactly what I wanted.
I only regret the lack of websites dedicated to this software because it was not bad, to exchange some amp sounds.

OVERALL OPINION

It's been three weeks that I'm on it, hallucinating and every day, the sounds are really terrible, and I have a JEM7VWH BOSS GS10 as a sound card, no latency, the sounds are deadly, and I do it again without this choice any hesitation.
I had the opportunity to try out simulator amps, stomp, amp, but that ouahhhh, I can not believe it.
Now I'll have to buy a laptop in order to bring it with me in concert and rehearsal.
