Do I Need WD Discovery For Mac?
And the related question. Should I install WD Discovery for Mac? The answer.
Unlikely. In my experience most of the issues experienced by Mac users. When using Western Digital external drives have stemmed from using this software.
The software may clash with other software you run on your Mac. And when you update your Mac operating system. You can cause software features of WD Discovery and its associated software to break.
Resulting in a wait for the release of compatible software. Or delivery of bug fixes.
Much of the software services provided in WD Discovery is part of the Mac’s operating system. In fact, in some areas Western Digital recommends using the inbuilt Mac software. Instead of its software.
All that said. You could use WD Discovery on a Mac to check for and install firmware updates for your external drive. Or you can check for firmware updates directly in Western Digital’s support area.
You could use WD Discovery to check on your external drive’s SMART attributes. And see if they threaten drive failure.
There are other services and ways to download your social media files from Facebook. Or from Instagram. And all the cloud services allow you to download your files to local storage. Including your external WD drive.
You’d use Google’s, Dropbox, or the other services own cloud app interface to do it. Rather than the Discovery software.

For the external drives that have 256-bit AES hardware encryption. You’d switch on and set a password for the hardware encryption on your drive using WD Security. You download this software through WD Discovery.
Mac OS also lets you encrypt your data on your external drive. And when you update Mac OS. There’s no worry about whether your WD security software is still compatible. Or wait for a new version for your MacOS.
WD drive utilities – software downloaded through the WD Discovery application. Checks on and lets you run software to format and check on your drive’s health.
Mac OS has these services inbuilt into Disk Utility. You run Disk Utility to format your Mac drive. Reformat your external drive and run First Aid to repair bad sectors on your drive.
For backup Western Digital recommended Time Machine on a Mac rather than WD backup. But with them now shipping Acronis True Image for Western Digital. Some Mac users may find value in using that software.
A few things to bear in mind. Acronis True Image software comes with a 5 year software license. After that? Who knows?
Plus, there is still the need to check the version you run. Is it compatible with your Mac operating system? Or when you upgrade do you have to wait for a version for your new Mac OS.
Personally, I think, when my backup depends on it, I prefer to run software I know will run and work on my Mac drive. Like Time Machine.
Is WD Discovery Necessary?
And a very similar question. Do I have to use their WD discovery software?
No. It’s not software you have to use on a Mac or on a Windows PC. There are plenty of alternatives and competing software solutions. And some of the software features Discover has are part of the operating system on a Mac. And on a Windows PC.
That said, some will like the software interface provided by Western Digital. You might like to try it out and see if you like it.
Just be sure to follow their directions for uninstalling the software thoroughly. If you decide you no longer want to use it.
Users have experienced software issues. With left behind pieces of the Discovery software.
