  1. What's the difference between App Store and Pro mode?

    Please visit the License Modes page for a full explanation of the different versions of Space Gremlin. If you have purchased a copy of Space Gremlin from the Mac App store, you can download Space Gremlin Pro and unlock it by importing your app store license.

  2. I purchased Space Gremlin and it won't install / failed to run.

    There are several reasons that an app purchased on the Mac App Store might fail to launch. If you're having trouble opening Space Gremlin or you see an error message that your license failed, please try redownloading Space Gremlin from the Mac App Store again.

  3. How do I delete files in Space Gremlin?

    Space Gremlin currently only lets you move files to the Trash, from which you can empty at a later time to recover free space on your drive. This mechanism is safer as it allows OS X to catch any files that you maybe shouldn't be deleting. Many novice users may not realize that deleting their System folder might end badly for them, and going through safe steps to remove files will help catch potential problems.

  4. Why does Space Gremlin show less Free Space then what's available in Finder?

    If you have Time Machine enabled on your Mac, you'll probably notice that Finder is reporting more available free space on your disk then what Space Gremlin is reporting. In some cases this can be as much as 20 GB or more. The reason for the discrepency is that Finder ignores any local Time Machine snapshots that it has saved to the disk. Finder treats these files as temporary, because the next time you connect to your Time Machine backup disk, these files will be moved over and deleted. The best way to delete these local backups is either to connect to your Time machine disk and let it perform a backup, or to simply disable Time Machine and then re-enable it.

  5. What is Restricted Space?

    The Restricted Space block in Space Gremlin refers to data on your disk that Space Gremlin cannot access. If you have a 100 GB disk that is completely full, but Space Gremlin can only find 80 GB worth of files, then 20 GB will be marked as restricted. In general there will be 3 types of data contained within a restricted block.

    1. System files. There are many files protected by the system from being accessed by a normal user. This includes the Spotlight data and system caches as well as root files. These files can be accessed by scanning in admin mode.
    2. Time Machine snapshots. Local time Machine snapshots are located with the .MobileBackups folder under your main disk. Snapshots can be anywhere from 50 MB to 20 GB of data depending on how long its been since you've done a backup. These files can be accessed by scanning in admin mode.
    3. File system metadata. This data will grow as the number of files on your disk grows. This data is not reported by Space Gremlin in any mode.
  6. How do I scan Restricted Space?

    Scanning Restricted Space requires you to open Space Gremlin in Admin mode. Admin mode should only be used by downloading Space Gremlin Pro and importing your app store license. To use admin mode you'll need to open Space Gremlin using the Terminal. Assuming you've places Space Gremlin Pro in your /Applications/ directory you can paste the following command into Terminal.

    sudo /Applications/Space\ Gremlin\ Pro.app/Contents/MacOS/Space\ Gremlin\ Pro
    You will be prompted to enter the password for your system. Once the application launches, you can scan any of your attached disks and you should be able to now view files that were once Restricted.
