How to back up macbook pro to WD My Passport for Mac
My old backup disk is full. So, I got a 2TB My Passport for Mac from WD.
I plugged it in and installed the utility. But when I went in to Time Machine and asked it to back up now, I received the message Backup Disk Not Available.
- Why am I getting that message? Is that because I have used another backup disk to backup before?
Then, after looking on the internet to try to figure it out, I went in to Time Machine on Preferences and tried to select my new disk. When I did that, and picked the new disk, I received the question:
"Do you want to stop backing up to "WD Time Machine" and use "My Passport for Mac" instead, or
back up to both? If you use both, Time Machine will take turns backing up to "WD Time Machine"
and "My Passport for Mac.""
I don't know the implications from either choice, so I decided to ask here.
I would appreciate help on this.
Thank you
MacBook Pro 15″, OS X 10.11
