Before you can use the PicoPix projector together with your Mac computer, you need to install the appropriate drivers first. A driver is a piece of software that tells the computer how to use the device that the driver is developed for. Usually, these applications (drivers) can be found on the CDs that come with different devices. If your PicoPix didn't come with a disc, check the following website, select your device and download and install the driver. After you did this, you should be able to project your presentation.
