OnyX icon

Preferences

To display the OnyX Preferences, choose Preferences in the OnyX menu. The preferences window displays five tabs.

To modify the appearance of the application:

You can use the Interface tab to modify the appearance of OnyX.

Turn on the "Drawer" graphic effect when opening OnyX panes.

You can use a local menu to choose the pane to automatically open when you open OnyX.

You can reduce the opacity of the main window by moving the Opacity slider (takes effect immediately).

You can use a local menu to choose another icon for OnyX.

To modify application behavior:

You can use the Behavior tab to modify the way OnyX functions.

You can choose to run the commands on the current account (by default) or on all accounts, if possible.

By default, when you should restart after running certain tasks, OnyX displays a message that asks what you want to do. You can choose to do nothing, restart, or shut down the Mac.

To update the application:

You can use the Update tab to set the OnyX update parameters and display the date and time OnyX last checked for an update.

To search, when OnyX opens, whether there is a more recent version of OnyX, select the "Check for update when OnyX is opened" option. If a later version is available, it will be placed on your Desktop (default option).

You can, however, modify the save path: click the Select button, and choose the folder in the next dialog.

Click the Check button to determine if a more recent version is available.

Display messages and OnyX Log:

You can use the Messages and Log tab to act on the various messages and OnyX Log.

When OnyX opens, OnyX displays, by default, the Software License Agreement. After having read and accepted it, you can cancel this display by deselecting the Display License Agreement option.

The Display Important Info option displays, when OnyX opens, some information which you should know before using OnyX.

The "Open OnyX log" option displays, at launch of OnyX, the Log window listing all the operations performed by the application.

Select the "Display message > Before quitting applications" option if you wish to be informed before OnyX forces an application to quit.

The "After executing commands" option displays an information message after running each operation.

When quitting OnyX, the application displays, by default, a confirmation message that you can choose to turn off.

By default, the OnyX Log is deleted after quitting the application, but you can choose to preserve it by deselecting the corresponding option.

Advanced Preferences:

You can use the Advanced tab to set the verification options when OnyX opens. There are three available options (Ask, Automatically check, or Don't check).

Check the S.M.A.R.T. status of the hard disk at application opening: This option performs diagnostics which prevent hard disk failure. It only works with ATA or Serial ATA hard drives. This option does not work with FireWire and USB hard drives in OS X. OnyX cannot check the S.M.A.R.T. status of RAID-arrays.

Verify the structure of startup volume at application opening: Since some tasks interfere with this particular option, OnyX will close all open applications. During the verification process, the Finder can become slow or unresponsive. The wait cursor (which looks like a colored pinwheel) can be visible, or the computer can appear to have stopped responding. This is normal, so wait for the verification to finish!
Note that this verification option is only possible when the hard disk is journaled.

Click the Restore Defaults button to cancel your modifications and restore OnyX to its default setting.
