Taccy – troubleshoot signature and privacy problems

Taccy examines an app’s Info.plist file and its code signature to discover its full settings for accessing protected data, particularly in Mojave. Helps you decide whether to add it to Full Disk Access, and debug problems with the privacy system, TCC. Ideal for advanced users, sysadmins, developers, security researchers, and anyone exploring macOS.
Taccy 1.10 (Intel-only for Sierra, High Sierra, Mojave and Catalina)
Taccy 1.15 (Universal App for High Sierra, Mojave, Catalina, Big Sur, Monterey, Ventura and Sonoma)

Signet – scans and checks bundle signatures

Scans a selected folder looking for apps and other bundles. For each found, checks it signature and reports any problems, including revocation, missing signature, or obsolete signature type. Invaluable for finding gronky old software, apps which have had their certificates revoked, and more. Does Gatekeeper’s job properly. Update can now check for notarization.
Signet 1.2 (Intel-only for High Sierra, Mojave and Catalina)
Signet 1.3 (Universal App for High Sierra, Mojave, Catalina, Big Sur and Monterey)

Precize – looks deep into files, bundles and folders to show their full size including extended attributes, provides macOS Bookmarks and volfs paths as enduring file references, and detailed information contained in Bookmarks and Aliases

Updated. Drag and drop items onto Precize and it tells you how much space they really take on disk, including all their extended attributes. It lists all inode data and gives volfs and File Reference URL paths to an item. It also provides macOS Bookmarks, and its integrated Bookmark Resolver locates and previews files from their Bookmarks. New version updates xattr code.
Precize 1.9 (Intel-only for El Capitan, Sierra, High Sierra, Mojave and Catalina)
Precize 1.12 (Universal App for El Capitan and Sierra)
Precize 1.14 (Universal App for High Sierra, Mojave, Catalina, Big Sur, Monterey, Ventura and Sonoma)

Alifix – refreshes Aliases and identifies broken Aliases

Scans folders deeply to identify and refresh all Finder Aliases, including those made by alisma. Reports all that are broken, and optionally writes adjacent text file with their internal details to help you repair the Alias. Full release with Help book and many improvements, now reduces time taken handling old broken aliases. Ideal before and after cloning or copying large folders or volumes, and as periodic housekeeping.
Alifix 1.1 (Intel-only for Sierra, High Sierra, Mojave and Catalina).
Alifix 1.3 (Universal App for High Sierra, Mojave, Catalina, Big Sur, Monterey, Ventura and Sonoma).

UTIutility – UTI scanning and conversion utility

UTIutility can scan folders to discover and list all the different UTI type designators used, and converts between UTIs, filename extensions, MIME types, and more.
UTIutility 1.0 (Intel-only for El Capitan, Sierra, High Sierra and Mojave)
UTIutility 1.1 (Universal App for El Capitan, Sierra, High Sierra, Mojave, Big Sur and Monterey)
UTIutility 1.3 (Universal App for High Sierra, Mojave, Big Sur, Monterey, Ventura and Sonoma)

Sparsity – create and find APFS sparse files

Updated. Sparsity creates APFS sparse files up to 999 GB in (expanded) size, and crawls through every file in a folder or volume to report which are in sparse format or have been cloned. For those, it gives expanded and sparse size, and the sparsity ratio (equivalent to a compression ratio). Help file includes example code in Swift to create and check sparse files.
Sparsity 1.3 (Universal App for Big Sur, Monterey, Ventura and Sonoma).

alisma – a command tool to create Finder aliases, and to resolve them to full paths

alisma is a small command tool which gives access to Finder aliases from Terminal and shell scripts. It has two options, one which creates a Finder alias to a given file/folder, the other which resolves an existing Finder alias to the full path to the file/folder. New version supports Sonoma.
alisma 2 (Intel-only for El Capitan to Catalina)
alisma 3a (Universal binary for El Capitan to Monterey)
alisma 4 (Universal binary for Big Sur, Monterey, Ventura and Sonoma)

Known Issues:

To use the log feature in Taccy, it has to be run from an admin user account. This is a limitation imposed in the log show command in macOS.
