Have a 13" White Macbook which I wanted to upgrade from Leopard OS 10.5.8 to Snow Leopard OS 10.6. Problem came up when we attempted to install the OS informing us that for Snow Leopard to install, the drive partition should be GUID not the Apple partition that was existing in the Macbook. This seems to leave me no choice but to create erase and create a new partition (i.e. deleting everything in the Macbook). Question: is there a way of installing the new OS without doing a clean install: i.e. save all my applications, preference settings, and data? Appreciate any help on the above. Alfie
Current Macbook has the Apple Partition Map. Installer disc says it should be GUID for Snow Leopard to install.
Apple Partition Map is supposed to be for PowerPC-based Mac. Is your macbook Intel or PPC? Snow Leopard is for Intel only.
The Macbook is an Intel Core 2 Duo running Leopard OS 10.5.8. 320 GB HDD 2GB DDR2 RAM. How do I install OS X 10.6 without reinstalling all of my applications and settings?
If the installer says you need a GUID partition then you have to reformat your hard drive. I can't think of any workaround to this one. Best you can do is backup your current drive. Reformat your drive and install SL then use migration assistant to move your applications and files from a time machine backup.
@alfiesy: Do you have an external hard disk handy? One without anything on it? The following might take some time. 1) Use Carbon Copy Cloner to clone the internal HDD to the external. 2) Once that's done. Restart using the External Drive as your boot drive. 3) Use Disk Utility to reformat your internal hard drive as GUID. 4) Use Carbon Copy Cloner to clone the external HDD to the internal again. 5) Boot using the internal HDD as the startup disk from Sys Prefs. 6) Install 10.6
