Mac OS X, a cinch.

Compatible with Garage Band (attention, resource-intensive) and with pro tools

See above.

Exemplary stability.

OVERALL OPINION

Used only a few days.

Amp sounds for software, intuitive ....; that good in my opinion, but the positive, I repeat, it is the sound .... and what a sound, we believe it.
I would do without a doubt the choice.
When the price / quality ratio is exceptional when comparing the sound quality for the price of the amps modeled in hardware.
