When using Time Machine on my new iMac the number of megabytes remaining for backup seem to be mistaken. Each time it starts up is says that it has about 925MB remaining to back up. It will then back up about 2MB and then it will finish that. It then says preparing and will do about a 1MB backup and will say it is finished. I think it is doing a correct backup b/c if I go into Time Machine it seems to have the new data. I'm just wondering why it says that there are 925MB remaining. Does anybody have an idea of what is going on? FYI, I'm using Time Machine through a Time Capsule. I also have a MacBook Air using the TC for TM and it seems to work fine. Thanks.
