Understanding MacBook Storage

Before diving into how to check your MacBook storage, it’s important to have a basic understanding of what it entails. MacBook storage refers to the amount of space available on your device to store files, applications, and operating system data.

MacBooks typically come with solid-state drives (SSDs), which offer faster performance and better durability compared to traditional hard disk drives (HDDs). SSDs have become increasingly popular due to their speed and efficiency.

MacBook storage is divided into two categories: internal storage and external storage. Internal storage refers to the built-in SSD or HDD that comes with your MacBook, while external storage allows you to expand your storage capacity using options like external hard drives or cloud storage services.

It’s worth noting that macOS system files and pre-installed applications take up a certain amount of space on your MacBook’s internal storage. This means that the actual available storage may be less than the total capacity advertised by Apple.

Understanding your MacBook’s storage capacity is crucial because it affects your device’s performance and limits the number of files and applications you can store. Regularly checking your storage and optimizing it can help you maintain an efficient and clutter-free MacBook.

Now that you have a basic understanding of MacBook storage, let’s explore different methods to check the available storage on macOS.
