Notice: This page contains information for the legacy Phidget21 Library. Phidget21 does not support VINT Phidgets, and will not support any new Phidgets. Phidget21 will be maintained until 2020. We recommend that new projects be developed against the Phidget22 Library.
OS - OS X
On Mac OS, Phidgets can be either plugged directly into a USB Port or run over a network using the Webservice.

Phidgets are designed to run on Mac OS 10.4 or newer, and can run on PPC, 32-bit, and 64-bit systems.
Getting Started (Libraries and Drivers)
If this is your first Phidget, we highly recommend working through the Getting Started guide for your specific Phidget device. If you already have the Preference Pane Installed and know how to use it, then you've already followed the guide and are ready to learn more about the workings behind the Preference Pane, the Phidget Webservice, and more - all specific to Mac OS.
If you are already a pro, and just want the drivers:
For special cases where you want to install the Phidget libraries without the installer, please see the Advanced Uses section.
The Phidget installer requires that your system has .NET framework 2.0 or higher. The .NET framework can be downloaded from Microsoft. If you do not have the .NET framework 2.0 or later installed, you can still use Phidgets. However, you won't be able to use the installer, and will have to manually install the Phidget libraries. Please see the Advanced Uses section.
To install the libraries, follow these steps:
1. Download one of the Phidget installer for your system, depending on whether your system is 32 or 64-bit.
2. Open up the installer, and open up
2. Proceed through the wizard.
Please note that by default, the installer places the Phidget libraries in
3. Once the installation is complete, you are ready to program with Phidgets.
Proceed onto to the next section where the Phidget Preference Pane will be discussed.
Phidget Preference Pane
The Phidget Preference Pane is a tool to quickly determine whether your system is able to control Phidgets, and also act as a debugging tool.
Once the Phidget libraries are installed using the installer, open up the
System Preferences window.
Click on the
Phidgets icon in the
Other section to bring up the Phidgets Preference Pane.
The general tab shows the list of Phidgets currently physically attached to the computer. You can also view the currently installed Phidget library version. You can double click on a Phidget device to open up an example program for the device.
In the above screenshot, the RFID example was opened. These examples are intended for demonstration and debugging purposes. If you have not yet already, please see the Getting Started guide for your device. It is important to keep in mind that when an example Phidget application is opened from the Phidget Preference Pane, it holds a lock on the Phidget. This prevents any other program from accessing the Phidget. Please ensure that this example application is closed(the Phidget Preference Pane can still be running) when you are running your own applications.
The next tab is the
Web Service tab, which allows you to control Phidgets over a network.
Here, you can start and stop the Webservice. Details are provided in the Webservice section. You can also determine whether the Phidget Webservice is currently running. There is also a check box that you can select to turn on verbose output, which will display useful troubleshooting information for the Webservice.
The next sub-tab is the
Output tab, which provides useful debugging information while you are using the Webservice. This tab will only show up if the verbose output option is selected in the previous tab.
Dictionary sub-tab comes next; it lists all the key-value pairs that gets created when the Webservice runs. More information is provided in the Dictionary section of the General Phidget Programming page.
Bonjour sub-tab gives a list of all currently attached Phidgets that are connected to the Webservice. This tab will only appear if you have Bonjour installed onto your system. You can also double click on the Phidget to connect to it over the network using one or more computers, and still use the Phidget on the computer it is directly connected to.
The last tab is the
PhidgetSBC tab, which displays the complete list of PhidgetSBCs connected to the network. You can double click on the PhidgetSBC to bring up the PhidgetSBC Adminstration Console. This tab will be enabled if you have Bonjour installed onto your system.
Summarize that we will be using code and the device manager to confirm and troubleshoot the installation, if needed.
This should walk you through compiling and running basic code against the libraries as simply as possible. Find an instance that requires no additional programs to run, and that will work with any Phidget, if possible. Recommended HelloWorld and gcc.
The point of this is to give the user tools to identify problems with the library setup that are not due to low level driver conflicts. The process should be described here (with the conclusion being the success of the check), followed by a referral to the Troubleshooting section (and content there) if failure results. See the OS - Linux#Software section for an example.
This should show you how to use the "About This Mac" program to make sure the Phidget is attached in hardware, and what to do if not.
Make an in-depth point by point section with some of this content plus more:
- Confirm prerequisites
- Walk through ALL known conflicting drivers
- Suggest attributes of unknown conflicting drivers
- Get people to the troubleshooting page if a non-OS problem is suspected
See the Linux Troubleshooting page for a briefer example. It is expected that with driver conflicts, this section will be much larger, with screenshots, etc. If you need to cover troubleshooting a problem with the webservice, you should put the content in the Webservice section below, and link to it.
We recommend the following languages for OS X:
Short description of the webservice on Mac OS (i.e. which files are the drivers, note that it is automatically on, etc)
Drivers for the Phidget Webservice on Mac are already included in the Drivers above.
If you have the Preference Pane installed, you already have the Webservice drivers installed.
Turning the Webservice On and Off
Detailed instructions, both at runtime, and disabling from boot entirely.
Setting Up the Webservice
How to find the port, computer IP, computer bonjour name, etc
Using the Webservice Without Bonjour
Detailed instructions on how to change your code to work with IP addresses
Using the Webservice
A walkthrough in C (using gcc) of how to write (i.e. modify) a remote program and screenshots of it running on localhost (127.0.0.1)
Debugging the Webservice
Examples of common errors in webservice-using code
Is there a way to enable debugging like there is on Linux?
Manual File Installation
A reminder of the installer and what it does, and how to do it manually when wanting to distribute our libraries with your code.
Description of Files
All files with the Preference Pane and their default installation locations.
Special Cases of Library Install
Cover how customers can distribute Phidget libraries with their code, refer them mostly to their appropriate language page.

If you wish to only install the things you need, please refer to your language page for instructions on how to manually install the libraries for your language.
also explain even more special cases on 64bit systems, if applicable(ie, c.
