NAW man!
I wanna use SX1&2 with Mavericks on my old G3 PPC and Steinberg should make that happen
for free and then send me a big fat cheque because I called them out on this forum!!!
Yeah That’s the ticket. 
But seriously, Arjan P is IMHO right on!
If your stuff works when you first get it, keep using it that way.
If you decide to update/grade any bit of your working gear, you take
the chance of breaking something.
Don’t do it. You can still create great music with the old stuff.
Just because someone puts different plate of food on the table
doesn’t mean we have to eat it.
