Os x 10.7.5 - Install Problems

Rosetta/PPC support was removed for sandbox security reasons.

Classic has been gone since 10.4!

Anyway - you can emulate classic on a new intel Mac with Sheepshaver.

As for PPC support on a new Mac that can't run 10.6: run a cloned 10.6 disk it in Virtual Box or VMWare.

Buy an older model iMac that will run OS 9.

Apple has traditionaly not been very suportive of games. Now with the focus on handheld devices the computers have less support especially for the older stuff. With the switch to intel processors the PPC has been abandoned. There were some PPC games that updated for playing on Intel hardware but are few and far between.

Unless you want to acquire an older Mac that will natively operate Mac OS9 or earlier, then consider Windows as a gaming OS. On the Mac Boot Camp is the best for games, but a virtual machine might be able to play the old stuff OK. Best of all would be a hopped up Windows 7 PC which can run Windows XP in a virtual machine for the antiques.

Interestingly "DOOM 3 BFG Edition" was recently released for the PC. I am currently playing it on a 2010 MacBook Pro via Boot Camp and having a retro blast. The Doom and Doom II are now at screen resolution and so much better than the originals. ( http://doom.wikia.com/wiki/Doom_3_BFG_Edition )

Here is a post that I assembled for another who needed to continue to run his PowerPC applications in Lion/Mt. 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 your PowerPC software or Lion/Mt. Lion;

3. Upgrade your software to Intel compatible versions, or find alternative software that will open your data files;

3. Install Snow Leopard (with Rosetta) into Parallels:

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.

For games requiring Classic, install SheepShaver or its cousin, Chubby Bunny:
