I am currently using a MacBook Pro, 2.33 Ghz, Intel Core 2 Duo. It is running OS 10.6.8; is close to 10-years old, and getting tired. My question has to do with the proper way to do a backup, considering that I plan to upgrade to a refurb MacBook Pro, no more that a couple of years old but running the latest OS. I do regular clone backups with Super Duper. Given that it backs up the entire OS (10.6.8) and all of my apps and data as a clone of my hard drive, is this sufficient to then upgrade and transfer all of my data and apps to a new computer? The old OS concerns me. Or should I be doing a different type of backup? I have apps that will need to be upgraded to work with the new OS but I want to insure the apps as they exist, will transfer so that I can do the upgrade and move on. Any help will be much appreciated. Thanks in advance!
