I think this might be a better spot rather than upstairs.
Rain has been down here too and I am sure he understands where I am coming from.
The problem here on the Sonar forum is you are getting a very one sided view of Macs. 99% of people here have been using a PC based program for a long time and they just have not come into contact with Macs at all. So they don't really know what they are talking about. They have just formed a biased opinion which is simply wrong and I mean wrong!
I have been on Windows too for a long time with Sonar and now Studio One for a long time as well and it all works fine on Windows. I recently came into possession of a powerful iMac for a very good price and decided to jump at it. At first I had some issues too and found it a little hard to get used to but after a while I just fell into it so easily and now I find Sierra just a beautiful and elegant operating system. So much so that Windows feels clunky and a bit horrible to me now in fact.
Studio One runs very nice on a Mac too and unlike Sonar trying to be ported over which is really not the way to go about it, Studio One has been on the Mac right from the very start. Not only has Studio One been written form the ground up but also written for the Mac ground up too and in complete tandem. All the way along.
(Mixbus/32C is also probably in this situation as well) So it runs sweet and it is painless moving from one platform to the other.
As
Rain has correctly pointed out Logic is also a beautiful app and been written for the Mac since day one so in a way it is really designed for it. I am about to get Logic too and as I used to use it before I know how marvellous it actually is. In many ways it is way more elegant than Sonar. And far ahead in some areas too.
I have not had a single issue installing and using Studio One. Installing plugins is so easy it is amazing. The thunderbolt port actually kills most things out there, end of story. Without any issues as well. Just plug in and get down to it. Seriously simple and elegant.
Transferring projects between the two platforms is also painless as I do it all the time now. You don't even need the Mac Pro either. A powerful iMac runs easily as fast as my quad core PC. Macs are not going away either. They are talking of a new iMac Pro coming that will probably be in the same ballpark as the current Mac Pro. And a new Mac Pro that will be fully expandable too. And more powerful. It is likely to leap ahead of the fastest PC's out there.
I love the way Macs don't boot up a mountain of programs either. They don't boot up anything in fact, just get you to the desktop. It is actually quite refreshing in this regard. No tweaking to get the computer to run music either. It all just works out of the box. They are a beautiful thing.
