    Since updating to 10.5.3, all my iMac Time Machine backups contain a mystery file, alongside the Applications/System/Library folders etc. I don't like the look of it. It's called a Mach_kernal file and it takes up over 10mb.

    I went to the trouble of an erase/install because I suspected something unpleasant, but it still appears on every Time Machine backup.

    Anyone have any info on this? Is this something that needs attention?

    Thanks in advance.

    A friend of mine also confims his iMac/Time Machine backups show it. So at least I know I'm not alone. I assume that if it's a situation caused by the 10.5.3 update, other Macs (apart from the iMac) might show it in Time Machine's Applications backups also.

    Again, any insights appreciated.

    That's the OS X kernel - the lowest level of the operating system. It's getting backed up along with everything else. I'd be worried if it wasn't there. ;)

    Thanks for letting us know what it is. But aren't I right in saying it was not showing in Time Machine before 10.5.3 update? I feel sure it wasn't. Pity I no longer have a pre-10.5.3 Time Machine backup to check :-(

    it was always being backed up, but maybe it just wasn't displayed. If you use tinkertools you can see all the invisible files on your hard disk.
