I am using a 2019 13-inch MacBook Pro with two thunderbolt ports. I have a WD My Passport external hard drive with a USB connection. In order to plug the USB into the Mac, I have a USB-to-thunderbolt adapter. However, the two thunderbolt ports on my Mac are so close together that I cannot use the power cable and the USB-to-thunderbolt adapter simultaneously.
When I try to back-up my Mac with the external hard drive using Time Machine, it says that "Time Machine can not back up because the computer is running on battery power. Connect the computer to a power outlet while your backup disk is available."
Am I missing something obvious here or is this a silly design flaw?
(1) How can I plug the Mac into a power outlet while simultaneously plugging in the external hard drive?
(2) Is there a way to override the Time Machine error so that I can just back up while on battery power?
Any help is appreciated.
