I have an iMac (2.5 GHz Intel Core i5) and I’ve just upgraded to El Capitan (version 10.11.2). Since doing that, I can no longer connect to my external drive (it’s a My Book Premium Edition II, Model WD10000C033-000). It doesn’t show up in my Finder, or anywhere else. It’s like the computer doesn’t see it anymore.
I looked to see if there were updated drivers, but I don’t see anything for OS 10.11.2.
Please give any advice you can, as I can no longer access the files that are on that drive from my Mac.
Thank you for any help!
