So I just set up my Board of Education (USB), and connected it however I get this when I try to ID it. Any Mac users run into this issue before?

You may be assuming that the USB connection is powering the Board. It only powers the USB to serial adapter and its LEDs. You need a 9V battery or power cube or other source of 6-9V plugged into the power jack. The on/off switch also needs to be in one of the on positions (1 or 2).
If you still can't get it to work and it's powered properly, call Parallax tech support. They'll help you get it working.
o.. Board Of Education (BOE) kit
o.. MAC OS X Yosemite 10.10.1
o.. MAC OS X 10.9.5
o.. Editor macbs2 pre-release3.1.5 (prerelease) (96)
I'll admit that I thought the USB powered the STAMP at first but after inserting a 9v battery, and checking it with a volt meter I realized I had other problems.
The fix was that I installed the recommended USB FTDI driver on both MACs and it then recognized the STAMP.
The drivers are located here: http://www.ftdichip.com/Drivers/VCP.htm
I used the x64 (64bit) package listed in the matrix, filename FTDIUSBSerialDriver_v2_2_18.dmg. There are 2 packages within the dmg, one for OS X 10.3, and the other for OS X 10.4 - 10.7. I installed the later (the 10.4-10.7) and it worked on both of my OSes listed above.
To bypass the security block, you will need to CTRL-SINGLE-CLICK the file and select OPEN-WITH->INSTALLER and select OPEN.
Once you have completed the installation.
1. Reboot your MAC (This is a must)
2. Install power source to BOE (I used a 9v battery)
3. Connect USB to MAC and BOE
4. Set switch on BOE to 1 or 2
5. Select the Serial port in upper right corner of macbs2 editor
6. Select "ID" on upper left of macbs2 editor or or run a program
You should now get a positive response that the STAMP has been recognized
I found reference to the FTDI drivers on Murat's site here (Thanks Murat for the editor and information):http://www.muratnkonar.com/otherstuff/macbs2-experimental/downloads.shtml
