Just got a Virus B on OS 2.8 and want to upgrade to 4.8

  • Evening, be gentle with me as a newbie to this forum. Had a Virus B a few years ago and loved it but had to sell, now just got another and its running OS 2.8. Downloaded all the appropriate stuff but just can't seem to get it to upgrade. I am using Ableton on a Mac and have it plugged in via a USB 2 port, its quite happily played sequences using Ableton but it just doesn't want to take the upgrade files. I note that in the past people have used Freeloader but that doesn't seem compatible with this Mac running Yosemite and those querys/answers were a long time ago - Any ideas.
