Is Helix compatible with Macs with a G5 chip?
Yes. However, all G5 based Macs boot only into OS X and can not be booted natively into OS 9. This means any non-OS X native Helix application running on a G5 will be running in Classic mode. Although the other applications work fine, we do not recommend running Helix Server in Classic mode. Helix Server 6.0 is OS X native, so using a G5 based Mac to run Helix Server requires Helix Server 6.0 or later.
