I am using a USB serial adaptor it shows up on the Device list. But not in the rumlog as a device. Not sure why that is. Anyone? Thanks.

You haven't installed the correct device driver.

I have the ATEN driver up to date. do you have another driver? Using this http://www.aten-usa.com/products/produc ... R1SbVxHHBI

To be exact I have this here http://www.iogear.com/product/GUC232A/ I went to the drivers for my iMac and got the latest one Sept 2014.

You should ask the manufacturer if it works for 10.10

If you had a driver that worked for Mavericks, odds are it will still work for Yosemite, but if it isn't signed then Yosemite won't load it. The easy way around that (until you can get signed drivers) is to put the KEXT security into developer mode:

Go to the terminal and enter the following:
sudo nvram boot-args=“kext-dev-mode=1”
<enter your password when requested>
sudo reboot

This will allow the unsigned drivers to load. In fact, it will allow any unsigned drivers to load, so use it with caution. There's a reason why Apple decided to lock down the drivers (security) and if you bypass it and something goes wrong, know that you've been warned. That being said, I've been running in developer mode since the day Yosemite came out (my Navigator does not yet have signed drivers) and I've had no issues.
