    So in an attempt to speed my machine up I downloaded onyx and cleared out the caches.

    However now my MacBook Pro is stuck on preparing backup in time machine, which I guess means I made a mess of a cache that time machine deals with..... Does anyone know how to make it re-cache/sort itself out?

    I'm on Mavericks by the way.

    Turn Time Machine off and back on (possibly with a reboot in between)?

    I will give that a go. I've also seen a comment about restarting the machine with it connected and trashing the in progress fike

    I use Time Capsule and through Time Machine in System preference the on off button is gone. How do I turn off Time Machine without the on off button?? Attached is a screen shot.

    How do I delete the In progress file. I just can't find it in finder.

    This will help you with the inprogress file.

    To stop the backup just click select disk there and remove the disk.

    Mine can get stuck if it losses connection with my NAS. I simply make a new AES connection and restart time Machine. But also, if I do a major update, change a lot of files, etc. it can take a long time (hours) to finish preparing for a backup.

    This worked for me in the same situation.

    Pondini is right about one thing.

    It does take very long time. But this time, it may not ever finish.

    I do believe that we need another guru to study what has changed in Sierra and make recommendations.
