Frequently Asked Questions

What is TinkerTool?

TinkerTool is an application which gives you access to additional preference settings Apple has built into Mac OS X. This allows to activate hidden features in the operating system and in some of the applications that come with the system.

TinkerTool does not provide any features itself. Its single task is to give you an extended interface to your personal preference settings. The tool will never change anything in the operating system. For this reason, the integrity of your system is not put at risk. All settings are restricted to the user accounts that launch TinkerTool. If you have multiple user accounts on your computer, settings of different users will not affect each other.

The feature set of Mac OS X varies greatly between different operating system versions. For this reason, TinkerTool must automatically adapt to the system it is running on. The settings available in each system version are listed at the official web page.

When you detect a preference setting that causes a compatibility problem with a third-party application, you can simply reset this or all preferences to their previous values.

Can I have a manual for TinkerTool?

There is no documentation other than this English FAQ list. Because TinkerTool doesn't provide any features, there is not much that could be documented. The tool has a single function: If you click on setting “X”, TinkerTool will change your personal preference setting “X”. Apple may change the meaning of setting “X” any time at their own discretion, so we have absolutely no influence on the effects each setting may achieve.

Is TinkerTool compatible with Mac OS X Server?

Yes, there is no difference between Mac OS X and the corresponding version of Mac OS X Server. The Server version only comes with additional administration and service software. So TinkerTool works the same on both system versions.

Could you please add feature “X” to TinkerTool?

In most cases, the answer is no. TinkerTool does not provide any features, so it cannot add any. The features you are seeing are provided by Mac OS X and controlled by Apple. TinkerTool is only a helper application to activate them.

However, if you know an additional built-in preference setting neither accessible in System Preferences nor in TinkerTool, suggestions are welcome. Note that we sometimes have to deny integration of a preference setting because the setting may have a negative effect on some applications (which is the reason why Apple did not make access to this setting publicly available).

I have enabled double scroll arrows at both ends of scroll bars. Why doesn't this work with iTunes?

All recent versions of iTunes use their own user interface which is basically not fully compatible with the Aqua design of Mac OS X. Unfortunately iTunes is not capable of supporting the preference setting to display four arrows in scroll bars.

Can the option Finder: Disable Desktop features have negative side effects?

Yes. Unfortunately, the Finder of certain versions of Mac OS X 10.4 Tiger might crash when it is quit if the option Disable Desktop features has been activated. If you are affected by this problem, uncheck the option and restart the Finder. This will resolve the issue. Apple has fixed this problem in later versions of the Finder.

Are there alternative ways to restart the Finder?

Yes, in up-to-date versions of Mac OS X, you can hold down the option (alt) key while right-clicking the Finder icon in the Dock. An item to restart the Finder will be displayed in the context menu.

There are .DS_Store files everywhere! Has TinkerTool destroyed my system?

No, you just have enabled the Finder's “show all files” option with TinkerTool. The .DS_Store files are created by the Finder during its normal course of operation but they are invisible by default. The Finder will automatically put a .DS_Store file into every folder you have opened. These files are used to save the positions of icons, the size of the respective Finder window, the window's background, and many more view options. While professional users consider the .DS_Store files to be a design flaw of the Mac OS X Finder, a mechanism like this is necessary when opening Finder windows for exchangeable disk media to give former users of the classic Mac OS the same user experience they had in previous operating system versions. If you don't like to see the .DS_Store files, disable the Finder option Show hidden and system files in TinkerTool, or replace the Finder by a better file management application.

Why is the Application option Disk Images: Skip checksum verification when opening DMG files inactive when I use TinkerTool on my system?

This indicates that you are using an operating system version in which Apple has already defined more detailed preference settings to control the checksum verification of disk images. Just launch Disk Utility and open its preferences panel. You will find detailed settings there.

Why is the Safari option Reimport Internet Explorer® favorites on next launch inactive when I use TinkerTool on my system?

This indicates that you must be using Safari 3.1 or a later version. If you haven't imported IE favorites with previous versions of Safari, Safari 3.1 will follow the strategy to always look for IE favorites, checking for a necessary import operation on each launch. For this reason the import cannot be deactivated and does not need to be renewed manually.

Why is the Safari option Redirect all links opening new windows into foreground tabs missing when I have Safari 5 on my computer?

For Safari 5, Apple made this setting official and even further policies have been added. The pop-up button of Safari 5 at Preferences > Tabs > Open pages in tabs instead of windows supersedes the older inofficial setting. TinkerTool is aware of this and disables the previous setting after you have upgraded to version 5 of Safari.

Can I completely disable font smoothing?

No and yes. Although Mac OS X does not support a feature to disable font smoothing generally, you can use the simple trick to set a very high size limit for the smoothing of fonts. If you set the limit to 144 points, basically all fonts in the user interface will no longer be smoothed.

Why can't I disable font smoothing for the standard font of the Mac OS X user interface?

In all current operating system versions, Mac OS X has lost the feature to change the font smoothing settings for the font Lucida Grande, the default font used in most Mac OS X dialog windows. This problem is not restricted to TinkerTool: Apple's original System Preferences application shows the same problem if you are changing the font smoothing limit in the Appearance preference pane. We made Apple aware of this issue, but they don't plan to fix it.

All icons in the Finder become gray when I enable the Finder option Show hidden and system files using Tiger. Is this normal?

Unfortunately, this is a known bug in all versions of Mac OS X 10.4 Tiger. We made Apple aware of this problem and they fixed it in Mac OS X Leopard and later versions.

How can I drag Dashboard widgets to my Desktop?

To successfully drag a widget to your Desktop please use the following detailed instructions:

  1. Make sure the option Dashboard: Enable Dashboard developer mode is checked in the Applications pane of TinkerTool.
  2. Open Dashboard. If you haven't changed the default keyboard settings, this is done by pressing the F12 key.
  3. Select the widget you want to have on your Desktop. Click in the widget and keep the mouse button pressed.
  4. While the mouse button is still hold down, move the mouse slowly and close Dashboard (by pressing F12 again) at the same time.

The standard widgets will disappear but the widget you are moving will stay on screen. When you release the mouse button you can use the widget like a normal application. To remove the widget from your Desktop, hold down the option (alt) key and move the mouse cursor onto the widget. A close button will appear which allows you to remove the widget.

Can I use TinkerTool to let Mac OS X create files with less strict permission settings (applies to Tiger only)?

Yes and no. In general, each application has to decide for itself which permissions to set when creating new files or folders. It is not possible to force a general default setting for all new objects. (This would create serious security holes in the operating system and would make Mac OS X unusable.)

However, many applications don't care about permission settings when creating new files. In this case, Mac OS X applies a default security restriction to the permission settings. While it is not possible to set a default for the permission settings themselves, it is possible to set a default for the security restrictions that are applied to the permission settings if the application doesn't set stricter permissions.

By default, Mac OS X will not allow that new objects have write permission for the owning group and other users. (Typical permissions are owner: read & write, group: read, others: read.) You can for example relax this strict setting, removing the Don't allow write permission for the group default. This is possible with TinkerTool's Permissions pane, available in Mac OS X 10.3 and 10.4: Remove the checkmark at Group / Write file: Don't allow, log out, and log in.

If you apply this change, all applications launched via the graphical user interface of this user account will grant write permission to the group, unless an application itself decides not to grant write permission. In most applications, files will now be created with the setting owner: read & write, group: read & write, others: read).

This preference has no effect on applications launched via a Terminal shell which includes the X Window environment in most configurations. These environments can use the Unix umask setting of the shell to achieve the same effect.

Note: Files created by an AFP (AppleShare) or SMB/CIFS (Windows) file server may override this default mechanism because the servers can be instructed to establish their own security policy. Refer to the file server documentation for more information.

What is the difference between TinkerTool and the two releases of the program called TinkerTool System?

The applications share the same user interface and internal technologies. However, the features and target group of the applications are very different: TinkerTool is a utility that allows you to set personal preference settings Apple has built into Mac OS X. TinkerTool is not capable of changing any system settings or other settings that may affect more than your private user account. For this reason, you don't need administrative permission to use TinkerTool. The tool can be used in professional networks where you have limited access, for example students working with the campus network.

TinkerTool System on the other hand is directed to system administrators, consultants or experienced users that need to change and optimize operating system settings. This will affect all users that share a computer. Only user accounts with administrative permission can use TinkerTool System, Mac OS X does not allow access by standard users.

The tools do not share any duplicate settings or features. They complement one another, to have the full feature set you'll need both applications. It is not planned to offer the system tool in other languages than English and German.

How can I remove TinkerTool?

Just drag the application to the trash. Because TinkerTool doesn't install or change anything in the operating system, that's all. You might consider resetting Mac OS X's preferences you have changed via TinkerTool to the pre-installation state before removing the tool. (See the next item.)

I used TinkerTool for a while, then I deleted it. But all of its settings are still effective, what should I do?

As mentioned above, TinkerTool just changes user preference settings of Mac OS X. Applications will respect their settings no matter if TinkerTool is on your disk or not. If you want to reset your configuration, just open the Reset pane in TinkerTool, choose one of the reset buttons, log out and log in.

Why did Apple include so many hidden features in Mac OS X?

Of course we cannot officially speak for Apple, but there are several reasons why some built-in preference settings of Mac OS X are usually kept under the hood:

  1. Settings for professional users: Some settings, e.g. the preference to show hidden and system files in the Finder, are official features of Mac OS X but Apple intentionally does not disclose them to normal end users. Those features are documented to developers or to professional users which read the technical manuals of Mac OS X. This way Apple can keep the user interface simple, at the same time not excluding particular user groups from using advanced features.
    Especially in professional networks, system administrators even don't like the graphical user interface but prefer shell scripts and the Terminal command-line. So there are also cases where Apple considers it too costly to develop a graphical user interface, thinking that most users would not use it.
  2. OPENSTEP settings untouched by Apple: Technically seen, Mac OS X is not a successor of Mac OS but of NeXT's operating system OPENSTEP for Mach. This operating system contained several features which are still part of Mac OS X. In some cases, Apple does not want to touch some of the old features, because this could have the risk of unwanted side effects. For this reason, these functions have never been deactivated but are “sleeping” in the OS.
  3. Features hidden for design and marketing reasons: System developers usually think far ahead while designing their applications. For this reason they prepare or implement many features without a direct order. In some cases they “play” with some features or need them for temporary testing purposes. However, superiors or the marketing division might later decide that a feature is “too advanced”, “not needed by most users”, or “doesn't look right”. Because it can be very expensive and time-consuming to remove program code, those functions are only deactivated, not deleted, and we have another “sleeping” feature.

This list of reasons is not necessarily complete. The strategy of hiding built-in features is not unusual, you can see the same on other operating systems as well. For example, Microsoft® has a tool called Microsoft PowerToys (formerly called Tweak UI) which does a similar job on MS-Windows® as TinkerTool does on Mac OS X.
