I am trying to install final cut pro 6 onto my mac but a message keeps coming up saying its doesnt support a powerpc, anyone have any tips please?

Are you on a PowerPC Mac?

If so you will need to get an Intel Mac or PowerPC version of the software

You will need a newer version of that software. Or an Older Mac computer and an Older version of OS X to install and run that program.

No you can't install an older versioon of OS X on your new Mac.

If you have an Intel Mac and have recently upgraded to Lion or Mountain Lion; here is a post I made in another similar thread:

I do not have any experience with Final Cut, but if you have existing projects that you MUST access; then you are in need of a solution on your new iMac in Mountain Lion!

Unfortunately you got caught up in the minor miracle of Rosetta. Originally licensed by Apple when it migrated from the PowerPC CPU platform that it had used from the mid-1990's until the Intel CPU platform in 2006, Rosetta allowed Mac users to continue to use their library of PPC software transparently in emulation.

However, Apple's license to continue to use this technology expired with new releases of OS X commencing with Lion (and now Mountain Lion). While educational efforts have been made over the last 6 years, the fact is that Rosetta was SO successful that many users were caught unaware UNTIL they upgraded to Lion or Mountain Lion.

Workarounds:

1. If your Mac will support it, restore OS X Snow Leopard;

2. If your Mac will support it, partition your hard drive or add an external hard drive and install Snow Leopard into it and use the "dual-boot" method to choose between Final Cut Pro or Lion/Mt. Lion;

3. Purchase a used Mac that will run Snow Leopard (with the optional Rosetta installed) and continue to run FCE on that Mac (you can actually use Screen Sharing with a "headless" used Snow Leopard Mac Mini and use the screen from your other Mac to view and work FCP in the Mac Mini environment);

2. Upgrade to an Intel compatible version of FCP (such as FCP X) and hope it converts your existing projects to its newer format correctly. There is much debate that the newer version of Final Cut are eliminating many needed features; for example Final Cut Pro X vs. Final Cut Pro 6 -- many users are staying with version 6;

3. Install Snow Leopard (with Rosetta) into Parallels and then install FCE in the Snow Leopard environment:

NOTE: STEP ONE of the instructions must currently be completed on a Snow Leopard or Lion Mac and the resulting modified Snow Leopard.cdr install file can then be moved over to your Mountain Lion Mac for completion of the remaining steps.

NOTE 2: Computer games with complex, 3D or fast motion graphics make not work well or at all in virtualization.
