Snowleopard + Yosemite
So i need to have Snowleopard because of older photoshop but really because i am running Revit on parallels but disk warrior keeps on making my mac run better. My Diskwarrior disk is now damaged so i decided to install Yosemite on a partition 100GB i setup as a secondary startup system. All went well last nite and i was able to get Diskwarrior for Yosemite then run it to fix my directory on the Snowleopard partition. All good. Then went in and did a bunch of revit work on jobs. . . then wanted to switch over to Yosemite. Opened Prefs / Startup disk and no Yosemite showed up! Help! . . .
I will be doing the big cleansinski soon enough as i upgrade to newer revit (autodesk now "rents" it!). Plan is to back everything up re-create 2 partitions this time 700/300 gig out of my 1000 this will enable me to attempt to setup bootcamp as i understand that parallels is slower to run windows 8/revit. This is a huuuuuuuuuuuugggge deal as the saying these days goes. So i have till the 18th of February to do this as that is the date my Ultimate Building Suite expires. So how do i get Yosemite and Snow Leopard to co-exist?
Mahalo for any thoughts.
