Arduino Uno Stopping Programs

Development Tools IDE 1.x
1

I am new to the Arduino, and recently bought one and installed the software on Mac OS X. After trying out a simple function and got an LED light to blink, the light won't stop. Whenever the Arduino is connected to a power source, the LED light continues to blink 1 second apart. I have tried changing the delay time in the code, it still will not stop blinking at the same right. The real problem is that none of the other pins will work or seem to respond to code because it seems that the Arduino keeps looping on the same command. I have tried reinstalling the software, using an Arduino shut down code, and nothing seems to be working, so is it that the Arduino isn't compatible with OS X? Any help would be appreciated.

(By the way, the software is OS X Snow Leopard, so it isn't an older version like in the troubleshooting guide)

so is it that the Arduino isn't compatible with OS X?

If it wasn't, why would there a download for it? Many of us are using OSX with no problems.

I have tried changing the delay time in the code, it still will not stop blinking at the same right.

Can you post the code are you using? Does the new code work right after you upload but not after a power cycle?

I have tried changing the delay time in the code, it still will not stop blinking at the same rate.

Do you get any error when you upload the modified sketch? If so, what error?
