Newer Mac downloads require Stuffit Expander version 5.1.2 or higher. Download the free Aladdin Stuffit Expander for Mac (included with Mac OS X 10.0-10.3, but not with 10.4).

I am 99.99% sure that altsetting 1 is irrelevant, it was just part of the initialisation sequence that it tries different altsettings until it eventually works. The fact you get lights on and the final message verifies that the mbox 2 mini sent a response code back to the driver so its fully working. You just need to configure your sound server correctly, as in use JACK.Good luck.
I am able to run mbox2 just in Win7 partion but even on this partition upgrade to 1.48 is not functional. I tried it on Ubuntu 14.04. , 16.04, Xubuntu, Linux Mint, no reaction no light. So what could be wrong? 2b1af7f3a8
