sudo mdutil -E /Or an external drive named krypted:
sudo mdutil -E /Volumes/kryptedWhen indexing, you will see the mds and mdworker processes running. If the process does not seem to be completing timely, you can use lsof to see where it is in the process. If the indexing errors then try and manually reindex based on the file that you see from where it crapped out:
mdimport /Volumes/krypted/designingwomencollection/episode0101.movOr to mdimport the directory that might be problematic:
mdimport /Volumes/krypted/designingwomencollectionFinally, the attributes that are tracked by Spotlight are many. The metadata attributes themselves are typically in xattr. For example, Command Line Finder Tags (http://krypted.com/mac-os-x/command-line-finder-tags/). To see the raw metadata for a file, use xattr:
xattr -l /Volumes/krypted/designingwomencollection/episodelist.pdfThe output of which would include the following:
com.apple.FinderInfo: 00000000 00 00 00 00 00 00 00 00 00 1C 00 00 00 00 00 00 |................| 00000010 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 |................| 00000020 com.apple.metadata:_kMDItemUserTags: 00000000 62 70 6C 69 73 74 30 30 A1 01 55 52 65 64 0A 36 |bplist00..URed.6| 00000010 08 0A 00 00 00 00 00 00 01 01 00 00 00 00 00 00 |................| 00000020 00 02 00 00 00 00 00 00 00 00 00 00 00 00 00 00 |................| 00000030 00 10 |..| 00000032 com.apple.quarantine: 0041;520d0314;Safari;The more metadata (QuickTime and some other apps can put a lot of metadata in files btw) the more you’d see. You can assign metadata manually or even exclude directories from indexing if you see the system is stuck on indexing a given directory.

mdls /Applications/iMovie.appThis results in output similar to the following (I’ve stripped out a few fields as they consume a lot of space and aren’t super pertinent to what I’m trying to do here):
To just ask for one of these attributes, run the command along with the -name option in addition to the metadata attribute you’d like returned. For example, to see the bundle ID (kMDItemCFBundleIdentifier), use:
kMDItemAlternateNames = ( "iMovie.app" ) kMDItemAppStoreCategory = "Video" kMDItemAppStoreCategoryType = "public.app-category.video" kMDItemCFBundleIdentifier = "com.apple.iMovieApp" kMDItemContentCreationDate = 2011-09-28 08:04:34 +0000 kMDItemContentModificationDate = 2012-09-22 02:13:45 +0000 kMDItemContentType = "com.apple.application-bundle" kMDItemDisplayName = "iMovie" kMDItemExecutableArchitectures = ( i386 ) kMDItemFSContentChangeDate = 2012-09-22 02:13:45 +0000 kMDItemFSCreationDate = 2011-09-28 08:04:34 +0000 kMDItemVersion = "9.0.8"
mdls /Applications/iMovie.app -name kMDItemCFBundleIdentifier /Applications/iMovie.appNow, if you’d like to just quickly ascertain what apps on the system came from the App Store, use the mdfind command, along with whatever of the attributes matches what you want to know. Running mdfind for kMDItemAppStoreHasReceipt of 1 would look like the following and would result in a list of all apps on the system that came from the App Store:
mdfind kMDItemAppStoreHasReceipt=1Blacklisting all apps that are part of a specific category (and with regard to customer requests, that category seems to always be Games) is something we get a lot of banter about with customers. To determine this information for apps, you can run mdfind on kMDItemAppStoreCategory for Games:
mdfind kMDItemAppStoreCategory=GamesYou could then dump the contents of those into something that can blacklist apps (or whitelist based on other categories). Now, version control is another hot topic at various organizations. To see the version type of a given app, use the -name option with mdls kMDItemVersion
mdls /Applications/iMovie.app -name kMDItemVersion /Applications/iMovie.appThen you can track the version of the app and take action through other ways to remove old versions and force users to upgrade. The mdfind command can also be leveraged to find apps that have escaped their traditional homes of /Applications and /Applications/Utilities, with the ability to obtain a full list by querying for kMDItemContentType of app bundles, as follows:
mdfind kMDItemContentType="com.apple.application-bundle"Loading a list of apps (output from `mdfind kMDItemAppStoreHasReceipt=1` or `mdfind kMDItemAppStoreCategory=Games`) into an array and then querying each one of them for more information is pretty trivial beyond the steps we’ve already taken. This information can then be fed into some kind of Managed Prefs script to deny or allow access to various objects or an admin could even chmod the bundle, mark it as invisible, poison it (keep in mind, if you alter it you’ll break the signing), etc in order to get some desired outcome. You can also use defaults to read a users com.apple.storeagent.plist file for the AppleID field to see what AppleID is currently logged into the AppStore, providing another variable that can be reported on:
defaults read /Users/cedge/Library/Preferences/com.apple.storeagent.plist AppleIDAnd yes, it’s worth noting that users from another account or a system image, etc can be used to download apps so this one isn’t exactly certain but the purchaser isn’t stored anywhere within the bundle nor is it permissioned in a way that we can use to find the purchaser that way. There’s still a bit of a gap right now with regards to some of these technologies that Mac SysAdmins are managing. The consumeristic technologies such as App Stores are here to stay. We’re kidding ourselves if we think that we won’t be able to buy certain apps via Volume Licenses and have pkg installers for too much longer. Apple has made no indication that they’re dropping the results that can be obtained with a simple installer command, but with forcing signing on certain objects, gatekeeper and other technologies it’s hard to say what the future will really have in store for us. Getting to a point where we can report on elements of the App Store and hopefully eventually deploy objects through the App Store should continue to help bridge these factors, but I still see the need for additional binaries from Apple to be introduced to get the rest of the way there (or at least expose a method to me so I can go in there and buy an app through the method).
