If you have a Mac and you are very persistent and technician enough when there is a solution. It really works (I use it) but it's time consuming to install and configure (a good time):
1. Install a Windows emulator. VirtualBox vm is free. You'll find it on Google.
2. You will need a Windows 7 image can be found free on the Internet. Search on Google W7forums and picture windows
3. Next you will need the software because the Oximeter SPO2 unfortunately comes with a mini CD compatible with MAC. Search on Google by typing Software Informer and SPO2.
4. When the emulator is launched to connect the oximeter and click in the top menu on USB Devices and then the oximeter for Windows recognizes
5. Go oximeter menu and send the recorded data and you will see them appear in the SPO2 software
Good luck.
