Make certain that your Mac is compatible with whichever OS you plan to upgrade to.
#MAC OS X 10.6 8 DOWNLOAD HOW TO#
For Lion (OS 10.7) or Mountain Lion (OS 10.8), you need to go to the online Apple Store to purchase and get info on how to download. From there you should be able to download and upgrade to the most current OS (currently OS 10.9 – Mavericks). Go to the Applications folder and open “App Store”. Thank you, Thank you, Thank you I have been beyond frustrated since the beginning of July ever since I did an iTunes update only to find out with many many hours of research that my operating system did not support the update. Snow Leopard was publicly unveiled on Jat Apple’s Worldwide Developers Conference. It depends on what's stopping you from restoring them. If you wish to upgrade FROM Snow Leopard, make sure you are running OS 10.6.8. Mac OS X Snow Leopard (version 10.6) is the seventh major release of macOS, Apples desktop and server operating system for Macintosh computers.
Afterwards you can start up from your old OS or Snow Leopard by pressing OPTION key during startup. Alternatively, install Snow Leopard to a empty partition that has been formatted as Mac OS Extended (Journaled) with the GUID option. however, I recommend making a complete bootable backup before doing so in case something goes wrong during installation, such as power outage. Many people simply upgrade directly over the old OS installation. After installing, do Software Update (under the Apple Menu) to bring Snow Leopard up to OS 10.6.8. If your Mac does not have an optical drive, the DVD has instructions on doing a remote install from another Mac on the same network. Then purchase the Snow Leopard install DVD from the Apple Store. (If the word “Intel” appears anywhere beside “Processor” you have an Intel-based Mac.) To find out go to Apple Menu and select “About This Mac”. If you wish to upgrade TO Snow Leopard (OS 10.6), make sure you have an Intel-based Mac (Snow Leopard will not run on a PowerPC processor) with at least 1GB of memory and has Mac OS 10.5 or earlier.
