MacMetaMod is a droplet that allows Mac OS X users to easily add keywords to the EXIF data blocks of image files, and to change the embedded title and other tags.
There are many EXIF tools out there, but I haven't found one that is quick and simple enough that I would actually use it to routinely keyword my photographs. They are generally too clever and complex for my purposes. MacMetaMod is as simple as can be - select and drag one or a bunch of images, then type appropriate keywords into a box. You can find the keyworded files later using Spotlight to search for the keywords.
If you want to see more meta data but do not need to modify it, then take a look at the sister program MacMetaShow.
System requirements :
Mac OS X v10.4 or later
The droplet is a single Mac OS X application bundle, which you can download as a compressed tar archive from the bottom of this page. Simply download to your desktop and double-click on the tar file to get your droplet, which you can then move anywhere you want.
Drag one or more files or folders on to the application.
You will then be presented with an input dialogue box where you can type in some keywords and other EXIF data that you would like to have embedded in the file(s). If you want to leave the file untouched, click on "Cancel" or hit the "escape" key.
If you only selected one file, you will be shown what the current keywords in the file are, and will have the option to save them for later use, when they will appear in the pull-down menu associated with the keywords input box.
If you select multiple files, there is an option to "Prompt for each file", in which case the program will step through each file and present an individual input screen for each one. Otherwise the same keywords, title and author will be added to each file, and a progress window will appear during processing, which will also flash up any error messages that come from exiftool.
Advanced features :
Version history :
Modified keyword history list function to include only new keywords, and also made the function accessible when operating on multiple files.
Trap for ampersands in keywords and titles, and replace them with plus signs, because they cause terrible trouble when left alone.
Fixed bug that caused program to abort if option 'prompt-for-each-file' was invoked on a directory that included another directory.
Ameliorated problem with system buffer overflow when too many images are dropped on to the application. More files can now be dropped (up to a total of 4000 characters for all the filenames), and an explicit error message is given when this is exceeded.
Rewrote interface using Pashua, in order to be able to have more than one field per page.
Allowed for stepping through multiple files, with individual prompts.
For information on the old version, which is simpler and potentially faster on old hardware go to MacMetaMod v1.
MacMetaMod is driven by Phil Harvey's excellent ExifTool, and uses Sveinbjorn Thordarson's Platypus along with CocoaDialog, which are protected by the GNU General Public License, which means this droplet is too. Version 2 also uses Pashua.
The software is free of charge, but I have spent many weekends developing it, so if you use and appreciate it, and feel like making a donation of a few dollars to encourage me to produce more stuff, you can do so here :
What other people are saying about MacMetaMod : "It's almost worth buying a Mac just so you can use it".
