I recently had a new hard drive installed on my Intel MacBook Pro. System is 10.6.8. Prior to the new hard drive, I could run applications that used Rosetta, e.g. Quicken. With the new hard drive, Rosetta is no longer present, and I can't find out how to re-install it. Any ideas?
Yep. Normally when you try to run a PowerPC application under Snow Leopard a dialog box appears, indicating that said application can't run natively and you need to acquire Rosetta. If your Mac is connected to the Internet, clicking a button in this dialog box downloads and installs Rosetta.
If that isn't doing the trick, insert your Snow Leopard disc, open the Optional Installs folder on that disc, and double-click the Optional Installs.mpkg package. The Installer will open and you'll be prompted to click Continue a couple of times and then choose a destination for the installation. Choose your startup volume and click Continue yet again.
In the Custom Install on "nameofvolume" window that appears, enable the Rosetta option and click Continue. In the next window click Install to do just that.
