Hi, and welcome to JustAnswer! My name is XXXXX XXXXX I am excited to get started with you.Have you set up time machine yet?
Yes, and I have done the back-up many times...but can't seem to do the back-up today?
Are you receiving an error message?
No..I will try it again...I usully just plug it in and it will automatcally do the update to the passport.
Try this, click on the apple logo in the upper left corner. Choose system preferences and then choose Time machine. If there is an error, it will be listed there
Ok great. Have a fantastic day
