This comprehensive guide will walk you through the process step-by-step, making it easier than ever.

Understanding the Essentials

Before we dive into the specifics, let’s clarify a few crucial points:

• Why Mountain Lion? While newer macOS versions offer more features, Mountain Lion remains a stable and reliable option for older Macs. It’s also a great choice for those who prefer a simpler and faster operating system.
