![]() Although the daemon can receive messages from the preference pane as soon as they are sent, the preference pane must use synchronous messaging and poll for any messages sent by the daemon. ![]() However, the prefpane and daemon run in different "bootstrap domains" when the daemon is auto-started. TabletMagic uses CFMessagePort for messaging between the daemon and preference pane. The daemon can freely run in user space without any of the other components present. Some kinds of drivers –USB for example– need to run in the kernel, but TabletMagic doesn't require a kernel extension. It is currently localized in English, French, and Italian. The "TabletMagic" preference pane is an Objective-C / Cocoa plugin that provides a user interface to start, stop, and configure TabletMagic. The preference pane asks for an admin password on first-run and tells LaunchHelper to suid itself. "LaunchHelper" is a simple C program that the TabletMagic preference pane uses to perform any actions that require escalated privileges. The intra-application messaging interface is part of the tablet class, but this will be placed in its own class pretty soon. There's a class to represent the tablet, one for the serial port interface, and a small class to encapsulate UD-style tablet parameters. The daemon is a relatively simple C++ project. "TabletMagicDaemon" is the actual device driver that communicates with the tablet and produces Mac system events. If you want the daemon to start automatically when you boot the computer, you need to check the Launch at Startup option in the Extras tab. The panel will install the other components when you start the daemon for the first time. Installationĭouble-click the control panel to install it. This Page contains more information and help for TabletPC users. TabletPCs with "ISD-V4" or "Fujitsu P-series" protocol are currently supported. ![]() TabletMagic also works as a driver for TabletPC digitizers based on Wacom serial hardware. A USB to serial adapter will also be required. The minimum system requirement is Mac OS X 10.4. From the select Force Quit, Quit general will not work with unresponsive apps anyway.TabletMagic is an OS X driver for obsolete serial Wacom tablets. So if you are seeing an unresponsive warning in the dialog or the warning mentioned previously in the System Preferences you will need to select the TabletDriver in the list and click on the X button on the top right. The TabletDriver is the one that crashes, with me at least, oddly enough the TouchDriver seems more stable. Luckily there is an alternative, if you open the Activity monitor and search for Wacom you should see something similar to the screen shot below. This is a pain even though restarting with and SSD is quick enough it still means closing all the open apps and waiting an age for some to close like the Mail.app (seriously Apple how hard is it to fix this nonsense). The only solution it offers is to restart the Mac. When you look in the Preference you will see some warning similar to the image above. This seems to happen more often after the machine is woken from Sleep mode. ![]() The tablet driver for the Wacom Tablet occasionally crashes under Mac OS X.
