sur le site de Tinkertool...dans les FAQ :
I installed a previous version of TinkerTool, then added some other third-party preference panes. However, the Installer is unable to install the latest version of TinkerTool and I also cannot remove the tool or any of the other panes manually. What should I do?
It appears to have become the latest fashion to publish system utilities in form of a Mac OS X preference pane. Unfortunately, many panes come with defective installers that corrupt the permission settings of the System Preferences environment. In this case, you can no longer update or remove third-party preference panes, including TinkerTool. Do the following to solve the problem:
1. Try to remember which preference panes you installed after you had installed your first version of TinkerTool. The installer(s) of this/those pane(s) are likely to have destroyed the permission setup in your system. Complain to the authors of these tools.
2. Open the Terminal application.
3. Enter the following commands exactly as shown:
sudo chmod g+w /Library
sudo chgrp admin /Library
sudo chmod g+w /Library/PreferencePanes
sudo chgrp admin /Library/PreferencePanes
Note that the system will ask for your password after you entered the first line.
Mais moi j'ai jamais utilisé le terminal...y pas un autre moyen ? il me semblait que l'on causait d'un utilitaire Apple qui restorait les autorisations par défaut...
