Sleepyhead cannot find my CMS50F Oximeter (on a Mac)
I have a Mac running OS X El Capitan V 10.11.2, and a new CMS50F Oximeter (Ver 3.8).

I have installed Sleepyhead for Mac, as well as the SiLabs USBDriver.

When I try to import data from the oximeter, using the Import data directly from a device option, Sleepyhead cannot find the device.

Note: when attached to my Mac via USB, the Oximeter does not display as a device in Finder.

Does anyone have any ideas why the CMS50F is not being recognized by my Mac?

Hi swanzon,
WELCOME! to the forum.!
I don’t know the answer to your question but hang in there.
Much success to you with your CPAP therapy.

Apparently, the SiLabs v4 driver has some problems with El Capitan.

See: http://community.silabs.com/t5/Interface...d-p/155165

Hopefully an updated driver will be available soon.

Thanks much. I'll try a powered USB, as the thread notes it may solve the problem.

Otherwise, I'll wait for an update.
