The 2.1 version of ApogeeConnect for Mac was available to download on the developer's website when we last checked. We cannot confirm if there is a free download of this app available. We recommend checking the downloaded files with any free antivirus. This free software for Mac OS X was originally produced by Apogee Instruments, Inc. The application relates to System Tools.
From the developer:
Apogee Connect is a great tool for interfacing with Apogee’s line of USB sensors including quantum sensors, pyranometers, and UV sensors. Features include real-time readings, graphs, data logging (with customizable sampling and logging intervals), and the ability to initiate unattached field-logging, where the sensor head stores up to 10,000 readings when attached to a “always-on” USB power supply.
