Mac Specs: By Capability: Mac OS 9/Classic Support

The level of Mac OS 9/Classic support for each PowerPC G3, G4, and G5-based Mac is listed below. For complete specs on a particular system, click on the name of the Mac (left column). For all Macs that match a specific Mac OS 9 compatibility -- courtesy of EveryMac.com's Ultimate Mac Sort -- click the compatibility of interest (right column).

Please note that "Classic Mode" indicates a system can run Mac OS 9 applications within the Mac OS X "Classic Environment" provided with Mac OS X 10.4.11 "Tiger" and lower. Apple provides no support for Mac OS 9/Classic applications on any Intel-based Macs at all or on PowerPC-based Macs running Mac OS X 10.5 "Leopard".

Please particularly be mindful of asterisks, as these note that a system is capable of running Mac OS X 10.5 "Leopard" but the "Classic Environment" is only supported when running Mac OS X 10.4.11 "Tiger" or lower.

If you are not sure which Mac you have, look it up by Order Number, Model Number, EMC Number, Model Identifier or Serial Number with EveryMac.com's Ultimate Mac Lookup feature. If you need help, refer to Mac Identification.
