This makes it possible that non-administrative users regain permission to deactivate, reactivate, or delete their personal caches if the cache folders use Apple’s recommended default permission settings.
TinkerTool System no longer relies on Time Machine itself to detect whether Time Machine is configured for a network-based backup target. Because current versions of macOS 11 are too unreliable to perform Time Machine maintenance features on network servers, TinkerTool System now completely hides all its Time Machine features when it detects such a configuration.
The detail display for the current settings of System Integrity Protection has been updated for the latest macOS versions.
User guidance when changing the selection of startup jobs to repair when the repair operation is already running has been improved.

Release 7.11 (Build 210114)

Due to major performance problems and critical errors in Apple’s Time Machine interface for third-party applications, support for all features managing network-based backups has been disabled. (Disk-based backups are not affected.) The features are planned to be reinstated again as soon as this macOS component will work correctly in future versions of the operating system.
Communication with slow components of macOS in the background could sometimes be misinterpreted as alleged “hang” of the application. To avoid this, many user interface elements to control features of Time Machine, Spotlight, and CUPS have been changed over to asynchronous behavior.

Added new feature to display the notarization state of applications or disk images (macOS Catalina only).
The reference manuals have been updated with information that could not be published while the news embargo for macOS Catalina was active.
Evaluation mode (“Try Before Buy” testing) is now unlocked for macOS Catalina.
Fixed an issue where the list of startup jobs shown for the category User Service Login Item could be inaccurate, showing entries already deactivated.
Fixed an issue where the data portion of the Catalina system volume was not offered for specific maintenance operations.

Release 6.7 (Build 190916)

Added new feature to resize disk images (DMG files), hereby avoiding the flaws of Disk Utility.
Added further support for future versions of macOS.
The standalone version of TinkerTool System (tts in Single User mode) has been rewritten completely. The new “TinkerTool System for Recovery Mode” (ttsfrm) supersedes the previous emergency utility. This leads to the following advantages:
- Compatibility with present and future versions of macOS is improved, because Single User mode is no longer officially supported by Apple.
- For Macs with T2 security chip, it will no longer be necessary to change the security settings.
- Issues with keyboard debouncing on certain Mac models are avoided.
- Apple’s Single User mode terminal is avoided, so readability on systems with Retina screens is fully restored.
- The emergency tool can now use the full character set and a graphical user interface.
- Separate, proactive installation steps for the emergency tool are no longer necessary.
A graphical interface to disable or enable System Integrity Protection has been added to the emergency tool. The following features no longer make sense in macOS Recovery Mode and have been removed: file system check for the system volume, deleting Input Managers, rebuilding XPC caches, self-removal.
The feature to create macOS installation media now accepts destination volumes which have slightly less than 8 GB of storage. This takes into account that Apple’s installer is based on working with volumes (not disks) whose formatted capacity can be significantly lower than that of the physical storage device.

Release 6.6 (Build 190812)

Many internal changes to support future operating system versions.
Added new “ID Finder” feature for user and group accounts. After entering either account name, full name, POSIX identifier or UUID, the application will find the three remaining other items.
Added new log type to retrieve the macOS log for disk write events.
Added new log type to retrieve the macOS log for differential privacy submissions.
Added new log type to retrieve the macOS log for iCloud services.
Added new log type to retrieve the macOS log for baseband processor incidents.
Added new log type to retrieve the macOS log for telephony monitoring.
Added new log type to retrieve the macOS log for trust checks.
Added new log type to retrieve the macOS log for iPhone software updates.
Added new log type to retrieve the macOS log for iPad software updates.
Added new log type to retrieve the macOS log proactive events.
The user interface for license registration was redesigned.

Release 6.51 (Build 190625)

This update is necessary to maintain compatibility with new versions of TinkerTool (7.4 or later).
Added further support for future versions of macOS.
Better guidance for the feature to remove unsuitable update notifications for users who have a customized update server set.
Fixed a problem where the application could hang while beginning to display live output from external utility tools that have been started without privileged permissions.

Release 6.5 (Build 190611)

Major architectural changes have been implemented that make it possible to make many long running operations interruptible.
Added operating system setting for full protection against the “ZombieLoad” attack (Micro-Architectural Data Sampling Vulnerabilities). This setting can only be changed while System Integrity Protection is off.
Added operating system setting to disable support of the assistant for Captive Networks (automatic configuration of access to “hotspots”).
Added new feature to automatically repair a specific damage of the Trash caused by third-party applications. This feature has no permanent user interface, but will be activated on demand during startup of the application if necessary.
The system setting to optimize the operational parameters for use as server computer can now be activated even if macOS Server is not installed.
Fixed a rare issue where the autostart settings of third-party services could not be determined correctly if the affected executable had unusual permission settings.
Corrected a problem where new system services that have recently been added to macOS Mojave have not been shown as Apple-provided autostart component.
Added preliminary support for future versions of macOS.

Release 6.4 (Build 190508)

Added new feature to display “reveal in Finder” buttons for objects in the preflight list shown before deleting files as part of a clean-up operation.
Added new feature to check a file system hierarchy against a user-specified limit for the length of absolute or relative paths.
Added new warning feature for the ACL pane that makes the user aware if a selected file system may not support ACL permissions or uses virtual permission settings only. A new info panel offers guidance for inexperienced users.
When propagating permissions onto a large folder hierarchy, the temporary memory consumption has been greatly reduced for specific use cases.
Corrected an issue where specific locale settings of the user account could prevent a request to automatically free storage space of APFS Time Machine snapshots by a specified size to take any noticeable effect.

Release 6.3 (Build 190327)

Added new feature to remove all local Time Machine APFS snapshots from a selected volume immediately.
Added new setting to control whether FileVault should remove the decryption key for the system disk from memory when the system is entering standby mode.
Added new feature to immediately eject all volumes when saving a modified automount configuration that have been set not to be automatically mounted by macOS.
Added new feature to let the application copy itself to the system Applications folder if desired when the program is launched from the virtual distribution disk.
The internal diagnostics features have been completely rewritten to be still operative in cases where operating system logging is not usable.
The application has been made robust against dubious “cleaner” software that damages the launch configuration of the operating system.
Better error messages for cases where users fail to register the application due to accidentally installing a wrong license file through dragging.

Release 6.2 (Build 190212)

Added new diagnostics feature to retrieve the login time statistics from the operating system. Total login time per user or usage time per day can be reviewed.
Added a workaround for a defect in macOS Mojave which can hang the operating system for 7 minutes if an application asks the operating system for the complete list of group accounts in a configuration with a network directory service. All user and group panels show only cached accounts now. The complete list of accounts can be retrieved on demand by clicking an extra button in the panels.
User guidance for the selection of destination volumes was enhanced when creating macOS install media.
Fixed a rare issue where the application showed the message “Interrupted system call” instead of the true error message when trying to delete specific files shielded by System Integrity Protection.

Release 6.1 (Build 190121)

Added new option to the propagation of permission settings that can precisely simulate inheritance of Access Control Lists instead of copying them unconditionally. This emulates the behavior of old versions of macOS Server. The option to enforce activation of the inheritance flag was removed.
Added new option to the propagation of permission settings that can be used to ignore all locked files during the operation. This emulates the behavior of old versions of macOS Server.
Added new feature to the storage space overview feature that lists all system services that are currently registered to reclaim purgeable space.
Added new feature to create a text report for the results of a bulk integrity check of applications. The report can be printed or be exported as RTF file.
Added new feature to the check of absolute path lengths for deeply nested folders that not only tests existing objects, but additionally checks potential paths that would be created when copying the tested files to currently attached volumes.
Added new preference setting to force the application to use Apple’s “Identity Picker Window” instead of TinkerTool System’s own user and group account management panels. This is less comfortable and does not offer OS accounts, but can be used as a workaround for a bug in the macOS Mojave directory services client which could lock the system for several minutes if one or more external directory services are configured when the UI for account selection was opened.
Both the main application and the Standalone Utility now display the new “executable policy override” feature of System Integrity Protection if active in a custom configuration.
Keyboard control of the Standalone Utility was optimized once again.
The swap space volume (VM) is no longer offered as possible target for specific operations to avoid confusion.
A layout issue of the path control that presents the top search folder in the results sheet for overlong paths has been resolved. This avoids that the panel can become wider than the screen.
Broken symbolic links will no longer stop a propagation operation on the ACL pane, if the feature to propagate an Access Control List is active.
Support code for legacy operating systems was removed from the Issues pane.

Release 6.02 (Build 181122)

Added new feature to the Info pane to indicate whether your Mac uses Apple iBridge technology, which includes Apple T2 processors. A detail sheet shows additional information about its configuration.
Added small changes to the non-English user interface for cases where Apple has modified the translation of specific terms as of macOS 10.14.1.
The pane for the Emergency Tool has been redesigned and will now show a notice if your Mac uses an extremely small font in Single User Mode.
Links to Apple documentation in connection with the Quick Help feature have been updated, or removed respectively, if Apple is no longer publishing specific information.
Added a workaround for a keyboard control problem of Single User Mode that could affect the Standalone Utility. Depending on keyboard type and OS version, a single key press could sometimes be misinterpreted as multiple key events.
Clarified the misleading label of the option to disable the dark wake feature of macOS.
Fixed a compatibility problem with the automatic restart feature when the application was renamed.
Internal technical update for changes in network infrastructure affecting the evaluation feature.
The application will show more targeted error messages if licensing fails due to a misconfigured network firewall.
The distribution package now uses the latest Gatekeeper security features.

Release 6.01 (Build 181002)

This is a maintenance update which corrects minor issues.

Adds support for future versions of macOS Mojave.
Adds a workaround for a declaration issue in the latest versions of the macOS Mojave installation App which could cause the installer not to be accepted as valid for the creation of install media.
Several changes and optimizations in user guidance when working with startup jobs, login screen settings, and license registration.
Fixes an issue where a private Software Update Server could not be used when macOS enforced HTTPS with TLS and extended validation.
Fixes an issue where the application could not detect that it was already approved for full disk access on systems that had been upgraded from OS X 10.10 Yosemite.
Fixes an issue where the user interface might not have been enabled for specific Time Machine features when the backup was stored on a network server.

Release 6.0 (Build 180918)

Added full support for macOS 10.14 Mojave.
Added new log type for slow application response to the feature to review classic system logs.
Added new log type for slow shutdowns to the feature to review classic system logs.
Added other new log types to the respective category in the log overview menu.
Hundreds of other small changes and adjustments for macOS Mojave.
The following features have been removed because they are no longer part of macOS Mojave, no longer make sense, or have been superseded by new macOS features: removing language support packages, validating login items, enforced Trash removal, repairing Safari font issues, repairing App Store licenses, enabling support for external accounts on the login screen, disabling support for text mode console login, temporary removal of swap files.
The following features have moved to new locations: removal of Recent Items (User pane), reset of privacy settings (Applications pane).
