SD2 with an IMac...

Need some help here.  Been working with DOS/Windows based computers for a long time (since late 70's).  Was getting comfortable with the Windows based SD printer.  She who must be obeyed decided we need a MAC!  Got one - Nice but.... (learning curve like a telephone pole!)
Installed Repetier 0.56 for Mac.  Finally got the printer to respond to simple movement commands along X, Y & Z axis'.  Go to the Print Panel.  The temps are set by the Printer Setup.  Which I set at 185 extruder and 85 bed.  Printed OK with PLA on Windows.  Before I touch anything the print panel reads - Extruder TEMP - 0  then a box with my 185 Temp and a set button.  Same for the bed temp, only set at 85.  As soon as I turn on either the extruder or bed heater it goes form TEMP 0 to TEMP185 (box 185), and bed 85 (box 85).  Neither setting shows the temps coming up.  I felt the bed and extruder, and they were getting hot, so it seems to be working, but I have no idea of the temps.  I have selected the setting to monitor the temps every 1 second,but it doesn't seen to be working. 
Sorry bout the long post, but I'm trying to get things working with a rather difficult - and expensive - computer.

Thanx for any help.

Took a while to figure out how to get a screen shot - told ya, this Mac stuff is new!

Hope this works....

Notice - Heat Off - Temp 0 - Selected Temp 185 - same with bed.

As soon as I turn on either the extruder, or bed, the temp goes here...

I have checked 'Exruder & Heated Bed every 1 second'
I need to see the actual temps

Thanx for any help.
