Modifier 2: Release Notes

Support > MF2: RN

Modifier's purpose is to provide a GUI model to administer file permissions in Mac OS X. Mac OS X provides a limited interface to do this via the Finder (the 'Inspector'). However, this function limits the user to changing privileges only for the files, not the owner, group, or other file attributes. As well, you can avoid those perplexing and clunky Terminal commands! Modifier ultimately walks the fine line between a browser and an info window extension, and may at one time move more in one direction or the other.

What's new:

  • Drag and drop support is now implemented.
  • Multiple document architecture allows you to use many info windows at one time, and to open/drag and drop more than one file to be opened at once.
  • View the item's icon, creation date, modification date, size, posix permissions number (i.e. 777), file kind, creator code, and type code.
  • Change the item's modification date, posix permissions number, privileges by user, group, or other on a grid, uid, gid, and sticky bits, creator code and type code.
  • File operations - You can now launch, move, copy, duplicate, or destroy the active item, as well as making aliases, or move the item to Mac OS X's Trash can instead of immediately destroying it.
  • Preferences - You can use items like transparent windows, select various actions for startup, use short names, calculate folder sizes, and more.

UFS Compatibility:
It should be noted that the UFS file system will not be officially supported, though many functions of the application will still work on UFS. HFS+ file systems support certain attributes that UFS theoretically does not, such as the creation dates, invisibility, and locked flags. In testing, files that were created on HFS+ and were copied to a UFS file system retained their HFS+ flags, and worked without difficulty in Modifier. Your mileage may vary. UFS behaviour is something that we would like to improve. It would be very much appreciated if you could e-mail your experiences with UFS and Modifier to
