Sfortunatamente, Java 7 è disponibile solo su OS X per Mac basati su Intel con Mac OS X 10.7.3 (Lion) o successivo.
La pagina Requisiti di sistema per Mac OS X per Java 7 afferma:
Mac OS X System Requirements
Intel-based Mac running Mac OS X 10.7.3 (Lion) or later.*
Administrator privileges for installation
64-bit browser
Note that installing Java on a Mac is performed on a system wide basis, for all users, and administrator privileges are required. You cannot install Java on a single-user basis.
A 64-bit browser (Safari or Firefox, for example) is required to run Java 7 on Mac OS X. 32-bit browsers such as Chrome do not support Java 7 on the Mac platform.
*Users with Mac OS X versions 10.6 and below should go to Software Update under the Apple menu to look for updates.
Ci sono alcune versioni molto vecchie disponibili per PowerPC su SoyLatte , ma potrebbero non essere adatte.
