This is just a crazy issue. I backed up my Mac on 10-31 prior to installing Yosemite -- to my time capsule. I have not been able to "talk" to my time capsule ever since. I have spent 30 minutes on phone with Apple support and three trips to various Apple stores with the last experience VERY UN-Apple-like as the Geek tech refused to acknowledge there is any issues with Yosemite -- denying any information on the Apple website. He insists the issue is a broken time capsule and ordered a refurbished capsule to the tune of $259.00 --- with a new one at $299.00.
I would believe him except for all the posts here and a further strange happening. I have reinstalled Yosemite to the latest patch level. IN ADDITION, MY SIGNIFICANT OTHER HAS A MAC, UPGRADED TO YOSEMITE AT THE SAME TIME (WITHOUT A PRIOR BACKUP) AND HE CAN ACCESS MY TIME CAPSULE.
So, is it the time capsule or Yosemite? I'm leaning toward Yosemite.
Any suggestions and yes, living in hope that I do not need any files from my backup until Apple acknowledges and fixes this...?
Thank you and yes, I feel you pain.
