SUMMARY

To upgrade from Mac OS 10.4.11 to 10.5, users must purchase the 10.5 version as it is not a free update. The iPhone Development SDK requires Mac OS 10.5 or higher for installation. Users with Intel Macs should consider delaying the purchase of 10.5, as Mac OS 10.6 ("Snow Leopard") is expected to be announced soon and will offer improved efficiency on Intel architecture.

PREREQUISITES
  • Understanding of Mac OS versioning and upgrade processes
  • Familiarity with iPhone Development SDK requirements
  • Knowledge of Intel Mac architecture
  • Awareness of upcoming software releases and their implications
NEXT STEPS
  • Research the features and improvements of Mac OS 10.6 ("Snow Leopard")
  • Explore the installation process for the iPhone Development SDK on Mac OS 10.5
  • Learn about the differences between Mac OS 10.4.x and 10.5
  • Investigate the performance enhancements of Mac OS 10.6 on Intel Macs
USEFUL FOR

Mac developers, software engineers, and anyone involved in iPhone application development who needs to understand the OS requirements for the iPhone Development SDK.

I was thinking if I have to buy new cd for getting 10.5 version or I can update to 10.5 from 10.4.11?
Eventually, I am installing iPhone dev SDK and was thinking if I need 10.5 for that ...

Thanks.

You have to buy 10.5 if you're at the 10.4.x level or below. When only the third component of the version changes, it's a "minor" update that you can download for free.

Suggestion: If you have an Intel Mac, don't buy 10.5 now unless you really need to upgrade in a hurry. There are rumors that 10.6 ("Snow Leopard") will be announced at MacWorld next week and will be available in the next couple of months. It's being designed to be significantly more efficient on Intel Macs.
