    Deleting incompatible apps & extensions
    I recently read an article about finding how many apps and extensions are outdated with the current OS (Mountain Lion). The article suggested I open the system profiler and look at the application list. There I found many Classic as well as PowerPC applications and files listed because I am a long time Mac user who has migrated to newer machines and operating systems.

    My question is, is it safe to go through and find these and delete them. I did see some Lion apps like iCal and Address Book that have a diagonal line through them in the Application folder. But in the profiler there are many that I have to track down through the profiler. Like this one when I highlighted this file in the system profiler:

    Appearance:

    Version: 1.1.4
    Last Modified: 8/26/99 1:00 PM
    Kind: Classic
    Get Info String: 1.1.4, Copyright Apple Computer, Inc. 1997-99
    Location: /System Folder/Control Panels/Appearance


    So far I have only put these in the trash. I have not hit 'delete trash' yet. I'm waiting for feedback. Thanks

    It's safe to remove any application that is "classic" or coded for the PPC. Lion and ML will no longer run any application that is coded for the PPC. And classic apps have been long gone.

    Thanks for responding. I assume the same is true for all those preference files I'm finding as well?

    Yes, as long as you delete the correct preference files.

    Yes. the preference files associated with PPC programs are usually safe to delete as well although the y do not take up much space if you choose to leave them behind.

    If you accidentally delete a preference file for one of your current programs it usually only means you have to recreate a few settings the next time the program runs.
