Workarounds for specific issues

Specifying a time interval when querying the macOS log database may not work: If you use the feature Info > Logs and specify a time interval at Time range, filtering by date and time may not work correctly with some macOS installations. Instead, the operating system returns entries for the entire recorded time range available. TinkerTool System detects this problem and will give you an error message in this case.

Workaround: This is a known defect of macOS. Only specific system installations are affected. We have informed Apple about this problem and hope they will fix it in future versions of the operating system. In case TinkerTool System detects this issue on your Mac, please see the recommendations given in the error panel for possible workarounds.


When macOS asks for permission to let TinkerTool System execute a privileged operation, the password panel has no keyboard focus: Depending on the authorization policies set forth in your operating system, macOS automatically opens a panel to enter name and password of an administrator each time TinkerTool System likes to perform an operation which requires more than the usual rights of your user account. In this panel, the password entry field is not pre-activated, i.e. it does not receive input from the keyboard immediately. You have to click onto the panel or its fields first before you can type your input.

Workaround: This is a known defect of macOS. Applications which use multi-tier privilege separation (like TinkerTool System 5) to fulfill Apple’s highest standards for system security cannot force macOS to display an authentication panel that becomes active immediately. We have informed Apple about this issue and hope they will fix it in future versions of the operating system.


When macOS asks for permission to let TinkerTool System execute a privileged operation, the password panel may contain text in different languages: Depending on the authorization policies set forth in your operating system, macOS automatically opens a panel to enter name and password of an administrator each time TinkerTool System likes to perform an operation which requires more than the usual rights of your user account. If the user’s preferences are set to show the user interface in a language different from English, this panel might contain a mix of English and non-English parts.

Workaround: This is a known defect of macOS. We have informed Apple about this issue and hope they will fix it in future versions of the operating system.


The option not to remove language support packages from embedded bundles cannot be switched off: The pane Languages provides an option to remove language support packages from all software components, even if these components are nested inside other components. The corresponding setting is always switched on. The check mark cannot be removed.

Workaround: At this time, this is the intended behavior due to a known defect of macOS. Although Apple’s packaging guidelines for software confirm that language support packages can be removed at all nesting levels without harming the affected software bundles, the current implementation of Apple’s code signature checks violates this rule. The digital seals of applications such as the Finder may become invalid when language support packages are removed at deeper levels of the application bundle. We have informed Apple about this issue, but they currently have no interest in fixing it. The associated option may need to be removed in future versions of TinkerTool System.


Although the Faults and Errors mode of the Console application confirms that no errors have occurred, the log feature of TinkerTool System shows errors for the time interval in question: If you are using Apple’s Console application to review log messages and you activate its filter to only show “Faults and Errors”, it may never display any messages.

Workaround: This was a known defect of macOS. Update to macOS 10.12.4 or later to resolve this problem.


When trying to use text mode login of macOS, you only get a black screen: If you like to use the feature of macOS to work with the system in Darwin console mode, without a graphical user interface, as it is described both in the reference manuals of TinkerTool System and Apple, the system might become temporarily unusable. Instead of showing the login prompt in text mode, a black screen appears and the keyboard fails.

Workaround: This is a known defect of macOS. We have informed Apple about this issue and hope they will fix it in future versions of the operating system. In case your Mac has become locally inaccessible, but it is part of a network, you can perform a remote login via Secure Shell as administrator, and restart the system gracefully with the command “sudo reboot”. To protect your system against a possible local denial of service attack, use TinkerTool System to enable the option “Login > Special Features > Don’t allow to switch to text mode via ‘>console’”.


The feature to reset the App privacy database may not work as expected for specific domains: If you select some of the items in the App Privacy table on the Privacy pane and press the Reset button, there may not always be a noticeable effect on the privacy settings. Depending on what domain of personal data you had chosen, macOS may just ignore the command, reporting that the reset operation has been performed successfully.

Workaround: This is a known defect of macOS. Apple may or may not fix this problem in future versions of the operating system. If the automatic reset operation appears to fail, try to delete the individual items manually in the Privacy table of the Security & Privacy pane of System Preferences.
