WD Passport Ultra not lettting me transfer files or create new folder on Macbook Pro, El Capitain

Hi, I’ve been using WD Passport ultra 1 TB on Macbook Pro El Capitain. I just purchased a new WD Passport Ultra 2 TB, ran the WD app software that it came with (updated and overwrote the old one). But the 2TB external hardrive does not let me transfer files or create new files. It’s seems to be read only. Everything works fine with my old WD Passport Ultra 1 TB. Can you please help me, I followed all the set up instructions of the new 2 TB drive?

The new drive is formatted in NTFS for Windows out of the box. You need to use Disk Utility and format it for Mac or for Mac and PC.

Great! And thank you so much for the super quick response. Happy holidays!
