A previous questioner speculated that his external drive did not work due to being improperly removed. My passport simply no longer is recognized since upgrading to Big Sur. It worked perfectly prior to the upgrade. I'm finding that the low opinions about Apple are true. Is there another "upgrade" that can make my passport functional again?
Keatoncat, launch disk utility and on the side bar do you see your passport for mac listed? If so check to see how it is formatted. DO NOT REFORMAT. My passport for Mac showed up right away. Do you have the most recent version of the WD discovery software.
I hope this helps.

Your welcome. Maybe the cable went bad. Take care and stay well.
Thank you for your prompt attention. No, the passport does not show up. I did, however, attempt to update it, but apparently it is too old to do so. I was able to download two viruses in the process, which I removed! I think I will continue to backup the files I use regularly to a thumb drive. Thankfully, I don't depend on this computer for anything other than personal use. As of yet, I have not tried the passport in another computer. I intend to do so once I'm out of quarantine. Again, thank you so much for your help.
