Installing Rosetta from Snow Leopard

Question

Mac Pro mid 2010
Lion 10.7.5
Tried doing this without success.  Want to be able to use my FCS 6.
Thanks.

Answer 1

Here are all the correct facts with regard to FCS2 (FCP6) and Lion/Mt. Lion:
FCP 6 is a Universal application that WILL run in Lion and Mt. Lion.
The problem is that there is a bug in the installer program that makes it fail in Lion or Mt. Lion.
There are 4 solutions:
1.  Use the partition/external hard drive method to boot from Snow Leopard (if your Mac will support this method) and "dual boot" into FCP 6
2.  Install FCP 6 in Snow Leopard BEFORE you upgrade to Lion or Mt. Lion;
3.  Use Pacifist to install FCP 6 in Lion or Mt. Lion; or
4.  Use Jeremy Johnstone's Terminal method (as linked above) to install FCP 6 into Lion or Mt. Lion; and be sure to note ARIC's comment on June 4, 2012 for complete installation instructions for all discs.
There were some initial indications in the early Lion era that installing Rosetta from a Snow Leopard Install DVD into Lion would ironically get around this bug and allow FCP 6 to be installed (giving incorrect support to the notion that the installer was PPC and installing Rosetta would allow the installer to function in Lion). 
Subsequent problems from users who utilized this method have proven that this method is dangerous and should not to be followed.  There is one particular member of this forum that continues to propogate this method, unfortunately at the risk to those who follow his poor advice!

It came with lion.  I bought snow leopard to upgrade the mbp, then upgraded that to lion.
I think you meant to say it came with Tiger.
