How use Time Machine on new MacBooks?!!
Hi and tnxs for reading.
Since it is not possible to use a USB HD and the MacBook charger at the same time on new MacBooks with USB-C, how is possible to make full new Time Machine backups on external drives in case of 300-400 GB data since in that case an encrypted TM backup would take more than the MacBook battery life?
Many tnxs.
MacBook Pro, OS X Yosemite (10.10)
