Taccy – troubleshoot privacy problems

Updated! 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. Now checks notarization on Installer packages too.
Taccy 1.4 (Sierra, High Sierra, Mojave and Catalina)

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 (Mojave and High Sierra only)

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

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 has auto-updating, control over text sizing, and more.
Precize 1.9 (El Capitan, Sierra, High Sierra, Mojave and Catalina)

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 (for Sierra, High Sierra, Mojave and Catalina).

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. First full release has extensive Help book and more.
UTIutility 1.0 (El Capitan, Sierra, High Sierra and Mojave)

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 and existing Finder alias to the full path to the file/folder. Now signed, hardened, notarized, and compatible with Catalina.
alisma 2 (El Capitan to Catalina)

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.
