hi i used the disk utility to restore the mac os x disc into a partition, from which i booted my mac and used it to install the system. but the disc is 10.5.0. so every time i finish installing, i have to update. is there a way that i can integrate 10.5.7 into it? the system sold in the retail store is already 10.5.7, i wonder how to make it? although the 10.5.7 package can be choose to install in that partition, it will freeze while the process. can i do it this way? if i can integrate it to the latest version, it will save me a lot of time.
