Just a quick question,

If i use a plugin in vst on my PC right now, and if this plugin exists in vst(mac)/rtas/au, will it transparently work if I open later the project on a mac which has this plugin installed on its own version ? or does it do a distinction between them ?
 
I have a huge problem on making my previous projects work well transfering them from my old WinXP PC to my new Win7 Laptop =O even having the same plugins!
