I have been searching for a way to run my classic apps on my new mac, but haven't found a good solution. tried using SheepShaver, but the dock icon bounces for 3 seconds before crashing, and I doubt that I can install classic support under 10.6, so is there any other way? thank you very much!
When you say "Classic" I'm guessing you mean OS 9, in which case SheepShaver is the way to go. Get the Classic-on-intel (COI) package from your bittorrent tracker of choice, then, after following the provided setup instructions, replace the bundled version of Sheepshaver with the latest build (from here). It should work fine after that.
If you are referring to pre-OS 9 apps, then you might want to try Basilisk II (for 68k and OS 7/8 apps), or even mini vMac (for Mac Plus era software)
