This past week, I received a phone inquiry from a client who asked whether Mac OS X 10.5 can be installed on a used G4 laptop. He said it wasn’t an emergency, so I emailed him my response, which was as follows:
Here are the system requirements for running Leopard:
1. Intel or PowerPC G5 or PowerPC G4 that has an 867 MHz or faster processor.
2. 512 MB of memory or higher.
3. DVD drive for installation.
4. 9 GB of available disk space.
To compare the specs of your laptop with minimum system requirements, select About This Mac from the Apple menu and click the More Info button. Alternatively, start a Finder window and navigate to the Utilities folder. Afterward, click on System Profiler.
