xattred – full-featured extended attribute editor, can also add quarantine xattrs
xattred lets you inspect and edit all extended attributes (xattrs) associated with a file or folder, cut/copy/paste any xattr between files or folders, create your own new xattrs with arbitrary contents, and add a quarantine xattr to force a full Gatekeeper check without downloading the file. Now with a crawler which explores types, sizes, and content of xattrs, and supports drag and drop for opening files. Fully compatible with Mojave, including Dark Mode. New version adds support for automatic checking and downloading of updates.
xattred 1.1 (El Capitan, Sierra, High Sierra and Mojave)
Pratique – simple utility to mark document quarantine flags as clear
New! Pratique changes quarantine flags attached to documents so that they don’t cause a security error when set to open with an app other than the default. It doesn’t change those attached to apps, bundles, or archives, so that normal app security checks can still be carried out on those. This provides a more lasting way of preventing repeated security errors and refusal to open these documents. An alternative to Sandstrip. First full release, follows macOS convention and lets you see which flags it’s changed.
Pratique 1.0 (Sierra, High Sierra and Mojave)
Sandstrip – simple utility to remove spurious extended attributes
New! Sandstrip searches folders for spurious quarantine flags which have been attached to files by sandboxed apps, and removes them. Ideal when you encounter problems caused by these flags, such as in shell scripts which refuse to run, or documents which can’t be opened because of weird security errors. Doesn’t affect regular quarantine flags. Quick, and notarized for Mojave. An alternative to Pratique. First release, with multiple file and folder selection.
Sandstrip 1.0 (Sierra, High Sierra and Mojave)
SearchKey – adds metadata to any file to aid Spotlight search
SearchKey adds and edits five extended attributes which can be attached to any file (or folder), including creator, copyright, and keywords. These act as sticky markers, and are preserved in almost all file systems and iCloud Drive. They are indexed by Spotlight, and directly accessible in search criteria. Has single-file and batch modes to make life quick, simple, and search-perfect. New update for full compatibility with Dark Mode and notarized.
SearchKey 1.2 (El Capitan, Sierra, High Sierra and Mojave)
SearchKeyLite – lightweight tool to add metadata to documents to aid Spotlight search
SearchKeyLite provides a sleeker interface to similar features to those in SearchKey. This supports file drag-and-drop, can copy and paste all the metadata in single commands, and makes it even simpler to tag files with copyright information, etc. It lacks a batch mode, and cannot work inside bundles such as Photos Library, though. New update for full compatibility with Dark Mode and notarized.
SearchKeyLite 1.2 (El Capitan, Sierra, High Sierra and Mojave)
cmpxat – a command tool to compare all the extended attributes (xattrs) between two files, reporting any differences
cmpxat is to extended attributes what
cmp is for data in files: it compares them between two files, and reports all differences that it finds.
cmpxat 2 (El Capitan to Catalina)
