    Cool Can a 10.5 disk repair/maintain a 10.6 disk
    Have not seen this asked anywhere yet, but I would like to know. I am installing 10.6 on my macbook pro 2.53. I just installed 10.5, but found that system has a (I consider) bad defect of creating and then not being able to repair bad permissions. Anyway, I am hoping 10.6 will correct that problem.

    I have also a white macbook 867 ghz which is running 10.5. Question is, can I boot my macbook pro in target mode with the older macbook and work on the 10.6 disk from the 10.5 disk? Like repair permissions, defrag it, etc...

    G'day and welcome to the forums.

    No they are not interchangeable and different cats altogether. Take it you are referring to all those so called 'error' notices that come up- after running Repair Permissions? Just ignore them and you do not need to defrag an OS X disk in the normal course of things.
