TinkerTool System 8
After using a feature that requires an automatic logout or restart, the operation fails with an error message: If you use one of the features of TinkerTool System 8 for which a logout or a restart of the computer is required, performing the logout will fail. Instead you will receive the error message “The operation could not be completed successfully. … The following problem occurred: The operation couldn't be completed. Invalid argument”.
Workaround: This is a known issue with
build 230315 of the application. Download
version 8.4 Build 230317 to fix this problem.
Workaround: This is a known design flaw of the Privacy feature of macOS. The protection feature can be confused when working with multiple copies of the same application. Use the following steps to ensure that macOS grants permission to the intended copy of the software:
- Identify all copies of TinkerTool System of your computer, e.g. by using Spotlight.
- Delete all superfluous copies, keeping the correct one.
- In System Settings, go to Privacy & Security > Full Disk Access, authorize as administrator, and remove the entry for TinkerTool System if available.
- Re-add the entry for TinkerTool System.
Note that you can always keep backup copies of TinkerTool System on your Time Machine disks. This may not work when using third-party backup applications, however.
The size values for APFS snapshots on inactive operating system volumes can be wrong: Current versions of macOS are unable to determine the private size of APFS snapshots correctly if the snapshots belong to a volume of another macOS installation on your computer. In this case, you may receive a private size of zero and a tide mark at the 4.61 exabyte position.
Workaround: There is no known workaround. Apple’s Disk Utility is also affected by this issue.
If you specify a time interval while querying the system log, specific versions of macOS may return incorrect data in case the time interval is a few seconds around the startup time of a Mac with Apple Silicon: If you use the feature Info > Logs to get an excerpt from the system log and you specify a time interval targeting the first boot phase of an Apple Silicon processor exactly, macOS will often return an incomplete or empty log as result.
Workaround: This is a defect in current versions of macOS. It is currently unknown when and if Apple will fix this issue. As a workaround, you can try to shift the time interval by a small amount, e.g. by 10 seconds after the startup time. In most cases, macOS will then provide the correct excerpt from the logs. Macs with Intel processors are generally not affected by this problem.
