Hello erwin177,
Oct 20, 2019 c. Use a Mac with an older release of Mac OS to format your WD Passport drive. Download the WD Discovery software for Mac from the Western Digital site. This software allows you to check the disk health and you can format to HFS using that software. There are other options which are more complex if the above has not worked for you. If you have already registered with MacWD, please sign in now. User Name:. Remember Me: Password:. Home Privacy Policy Search Privacy Policy Search.
Thanks for the post in Apple Support Communities.
I understand you're unable to install an app downloaded from a website. Can you provide more detail about what happens when you try installing the app? If you get an error message, what does it say?
Which macOS version are you using? You can check by clicking Apple menu () > About This Mac.
This link is a great guide for installing apps on your Mac for reference: Install and uninstall apps from the Internet or disc on Mac. From your post, it sounds like one of the steps recommended in that link may be helpful if you're seeing an alert that the developer is unidentified. If that's the error you see, check out the details here: Open a Mac app from an unidentified developer.
I hope this helps get you started.
Cheers.
