Problems with plugins and installs on Intel Mac

Heylo guys and girls...

Scenario...going from an PowerPC G5 to Mac Pro...machine used for music production...

I started installing apps and plug ins onto the mac pro today. Logic Pro, IK Multimedia stuff, Native instruments etc etc...

Half of stuff I installed I cant find in the apps folder...where is it??? I installed 4 disc m-tron from gforce, i cant find neither does logic.
I installed spectron from izotope...nowhere to be found??? Not avaiable as plug in in logic???
I installed CSR and T-Tracks from IK Multimedia same thing.

I guess M-tron is not universal bin but i shold still be able to find and run it, right??
Spectron's update is uni bin but still not avaiable in Logic.

Are not native apps installed somewhere else???

Really clueless here and frustrated..HELP please

Anyone Out Ther With An Answe?????

I had the same problem with magic bullet editors on my intel mac with final cut.. I have not yet found a solution to finding the plug-ins, but if I do, i'll let you know how I went about solving it.

I looked on iZotops website and they list their plug ins as UB. Neither spectron or vinyl show up in logic? am i doing something wrong.
Now should rosetta not let me use stuff thats not ub???

I guess Logic Pro does not run with in rosetta ok so that explains why m-tron would not show up but why is spectron not there, that ub. and where did 4 gigs of sound files go..
