Good Evening, I was working abroad for a couple months and just returned home recently, I have an old early 2011 MBP that ran El Capitan and now that I'm finally reunited with it I finally upgraded it to Sierra last week.

Before upgrading it I plugged my time machine as usual and backed it up without issues, after I upgraded to Sierra the drive no longer mounts on my laptop, I let it connected for hours to no avail.

I have already checked the drive and there's no problems with it, the drive shows up under diskutil in terminal. if I hold option during boot with the drive plugged it'll show up as time machine as well. I tested the drive on a neighbor's Mac (OSX Mavericks) and the files are there; it was working perfectly on this one until I upgraded to Sierra.

Is there any workaround that I can attempt to get my Time Machine back up and running under Sierra? Thanks in advance & please excuse the grammar horrors, English isn't my native language.
