To find your best external hard drive for Mac, you’ll want to decide how quickly you want to save and retrieve data. Consider how you’ll be saving and transferring files, such as photos, videos, files from tablets, files from PC laptops, or photos from top-rated cell phones.Drive speed is measured in revolutions per minute (rpm), based on how fast the drive can spin. A drive formatted in this fashion can be swapped between a Mac and Windows PC. However, you might choose instead a format you can use easily with OS X, Windows, and Linux. Simple and easy to use, MacDrive is recognized as the leader for accessing Mac disks from Windows for almost 20 years. Once you plug in your Mac disk, behind the scenes MacDrive works to seamlessly enable Windows understand HFS+ disks and allow you to read and write to the disk.

Is your Mac up to date with the latest version of the Mac operating system (macOS or OS X)? Is it using the version required by some other product that you want to use with your Mac? Which versions are earlier (older) or later (newer, more recent)? To find out, learn which version is installed now.

If your macOS isn't up to date, you may be able to update to a later version.

Which macOS version is installed?

From the Apple menu  in the corner of your screen, choose About This Mac. You should see the macOS name, such as macOS Mojave, followed by its version number. If you need to know the build number as well, click the version number to see it.

This example shows macOS Catalina version 10.15 build 19A583.

Which macOS version is the latest?

These are all Mac operating systems, starting with the most recent. When a major new macOS is released, it gets a new name, such as macOS Catalina. As updates that change the macOS version number become available, this article is updated to show the latest version of that macOS.

If your Mac is using an earlier version of any Mac operating system, you should install the latest Apple software updates, which can include important security updates and updates for the apps that are installed by macOS, such as Safari, Books, Messages, Mail, Music, Calendar, and Photos.
