I have two Macbooks (A and B). A backs-up to Time Capsule (TC), while B does not. I used to mount TC and move files there, which I don't want to keep on A or B.

Few weeks ago it became impossible to mount TC on A, while B is still mounting fine. A continues to do backups to TC as usual. A does not show TC in left sidebar in Finder (B does), but one can find it via Networks. Trying to connect to partition takes forever. The partition is showed as mounted, however, /Volumes/ does not have it so as Disk Utility.

I restarted both TC and A, but the problem persists. Is there anything else I can reset to solve this issue?

Buttons to unmount and to "connect as..." do not respond:

    It looks like some comments are deleted, so I've moved this conversation to chat so that the clarifications can make sense and not confuse the wording of the question as it stands.

Re-adding the Time Capsule to Time Machine may work

I used to face problems with the mount. Removing the Time Capsule (TC) from A's Time Machine and re-adding helped.

Otherwise, the obvious ultimate solution would be to remove the A's backup from TC completely and take a fresh backup.

  • All these rather risky manipulations should only be attempted within a perfectly working network. And this doesn't seem to be the case here.

  • Hm, I hope I won't loose the old backups removing TC from A? I'll give it a try tonight.

  • @danielAzuelos Network seems working fine. I have 3 macbooks and 4 phones using it without noticeable issues. All of them are connected to TC directly.

    @Andrei: how do you explain A can't access TC? Could you check a basic ping to check it is really working?

  • @danielAzuelos B can mount TC. A shows TC as already mounted. I haven't had a chance to remove TC from A yet. Maybe today
