Sam Thank you
I would like to add some of my experience. My terminology and lingo are not that good. I had prevous problems with my TC and every now and than I check the backups via Time Machine app or by clicking the sparce bundle from Finder. Scince the last update I cant open the sparse bundle from Finder. I followed Sam advices
to see the content of TC backup sparse bundle:
I go to Disk Utility;
Right clik on Time Machine Backups and chose Show in Finder.
Now the sparse bundle opens and I can see each of the backups.
I would like add some more stuff. So far , in my case, time capsule wasn't always visible under Disk Utility ( I cannot say when it shows and when not). I had many talks with Apple Support. Some guys said that TC is NOT supposed to be seen in Disk Utility !!!
After this update 10.12.2 I can see TC every time I start the MAC and run Disk Utility.
After Sierra update I had to manually connect TC from Finder every time I needed its disk. Again some Apple employes told me that it is a new security feature: all network disk should be manually connected by the administrator. Interestingly others didn't know about this.
After 10.12.2 TC is connected all the time and there is no need to connect it manually from Finder.
