Question: Time Machine's Warning - Identity of the backup disk changed
Good evening to everyone,
today I've got this pop-up window from Time Machine:
Anybody knows what does it mean???
Of course I have not erased or replaced the disk. So mainly I'm asking, do I have to worry that really "someone may be trying to trick my computer into backing up to the wrong disk?" If so, one should have got access to my Time Capsule's Wi-Fi, but I'd say I'm using pretty strong WPA2 key also I have checked Wireless Clients list for unknown hosts, I haven't seen any, I can easily identify all of them.
Thanks in advance for help, some info or explanation, have good evening everyone,
