But still my Apollo Twin and UAD-2 Satellite didn’t locate, and I don’t know the reason why. I see many people doing the same OpenCore on Mac Pro 2010 5.1, so please what can I do to install OpenCore for my Apollo Twin and UAD-2 Satellite will work, and most all the times, if I turn on the Mac Pro without turning on the Apollo or the Satellite, the computer will come, but if I turn on the Apollo and the Satellite then the computer will shutoff and you can see for yourself. I was trying to send you a Video, but it seems not working. I will try and see if I can send it to you with dropboxThanksHi,If you are trying to use Thunderbolt devices please try as follows.1.
