Whether your precious Mac is a MacBook Pro. Or a MacBook Air. Or an iMac.

You’ve relieved your wallet of several dollar bills and bought yourself a SanDisk Extreme Portable SSD. Or a SanDisk Extreme Pro Portable SSD for your Mac.

And now your question as a Mac user is:- ‘How to use SanDisk Extreme Portable SSD on Mac?’

I’ve played with a SanDisk Extreme external SSD to get you the answers.

Either read this post in full or use the table of contents to hop to the tidbit you want to know all about. And start using your V2 Portable on your Mac super quick.

Ways You Can Use Your SanDisk Extreme Portable SSD on Your Mac

1. Drag And Drop. Or Copy and Paste Your Files To.

2. Work Direct Off Your SanDisk Portable.

3. As A Place To Put Your Photos And Videos.

4. To Back Up Your Mac.

5. Use To Share Files Between Your Mac And A PC.

And this is only for starters.

Does The SanDisk Extreme Portable SSD Work On A Mac?


Absolutely it does. You’ll find your solid state drive in an ExFAT format when you buy.

What does that mean?

Your Mac can read and write to your SanDisk storage space right away. And so can a Windows PC.

But you should think about reformatting it anyway. Even if you plan to share your storage space with a PC.


Because your Western Digital SanDisk external SSD comes set up as a Master Boot Record.

This is fine for a PC.

But when you’re using only on a Mac. Or mainly on a Mac. Your Mac won’t like that over time. You Mac needs GUID Partition Map as the scheme not Master Boot Record.

It takes less than 5 minutes to change. And you use software already on your Mac called Disk Utility to do it. You can find out how in this article here. Format SanDisk Extreme Portable SSD For Mac.

Or you can watch this video.

Just remember that if there are any files on your SanDisk drive you want to keep. Copy them off somewhere else first.

Formatting erases your Sandisk external storage.

How Do I Connect My SanDisk Portable To My Mac?

First things first.

Some quick facts.

Your SanDisk Extreme Portable drives come with a USB C port on them.

SanDisk Extreme Portable SSD USB C Port

And a USB C 3.1 Gen 2 cable in its box.

Connecting Your SanDisk Portable To Your Newer Mac

And if you’ve a Mac that’s a 2017 or later MacBook Pro. Or you’ve a MacBook Air 2018 or later.

Or perhaps an iMac 2016 or later. They all have a USB type C port.

Use the cable that’s in the box with the drive and plug straight in,

Your Mac NOT one of those?

Connecting Your SanDisk Portable To Your Older Mac

Then no worries USB will work on older USB ports.

Yes, your older USB type A ports are different. But YAY! In your SanDisk Extreme’s box, you’ve an adaptor.

Put that on the end of the USB C cable that comes with your portable SSD.

Just be sure to match up the arrows.

One more thing …

Connecting Your SanDisk Portable To Your Mac With USB 2.0 Ports

You can plug in using the adaptor. But;

USB 2.0 is from the days when SSDs with such speed weren’t around for your Mac.

So What?

Your SanDisk Extreme Portable drives will draw more power than your Mac can give them through its USB ports. And your drives won’t work reliably.

This means you’ll need to get yourself a USB hub with its own power. And use that to connect up your SanDisk portable SSD.

Now you’re ready to use.

How To Use SanDisk Extreme Portable SSD On MacBook Pro Or Any Other Mac

It doesn’t matter if it’s a M1 Pro, MacBook Pro, M1 MacBook Air Or iMac it’s the same.

You plug in and the SanDisk’s drive icon comes up on your desktop.

SanDisk Extreme Portable SSD Mac Setup

Format your SanDisk Extreme external SSD with Disk Utility first.

Files Already On Your SanDisk Extreme Portable SSD

There are files shipped with your SanDisk Portable SSD. And on the SanDisk Pro SSD flash drive. And you may have copied them off before formatting.

And if you didn’t, no matter, you can download them again from the SanDisk site.

What are they?

PDF’s and a program to access the hardware encryption on your SSD.

Anyhows. The Mac version of the SanDisk hardware encryption program isn’t on the drive. And you’d have to download that anyway.

You can download them if you’d like from this link here.

To Use The SanDisk Portable SSD Encryption Software… Or Not

You may decide that you’d like to use the SanDisk hardware encryption on your SSD.

But know if you do. That you’ll need the software to access your drive. And you’ll need it on which ever Mac you decide to use the drive on.

And you’ll have to wait and double check. Before you do any upgrade of the operating system on your Mac.

Because you’ll need to check that there’s a version of the hardware encryption driver for your Mac. One that works with your Macs operating system.


You can use the encryption features inbuilt into your Mac’s OS.

That way you don’t have to worry about OS versions. Your Mac and other Macs will be able to read the files on your drive. Without any special software. You’ll just need your password.

But for goodness sake don’t forget your password.

Whether you’re using the SanDisk Encryption software. Or the encryption on Mac. There is no coming back from forgetting your password.
