avrdude: stk500_rec(): programmer is not respondin

Hi .
I really need some help from someone. I bought an arduino board about a month ago as i need it to create a project for my masters in university (which has to be submitted at the end of August) I am having trouble uploading info onto the board from my computer. I am using an apple MacBook pro. everytime i try to upload it says avrdude: stk500_recv(): programmer is not responding. I have tried changing the serial ports, however the only ones listed are as follows:
/dev/tty.Bluetooth-PDA-Sync
/dev/cu.Bluetooth-PDA-Sync
/dev/tty.Bluetooth-Modem
/dev/cu.Bluetooth-Modem

should there not be some serial ports listed:
COM1
COM3
COM7
COM8 etc??

Please help me!!!

Have you installed the FTDI serial drivers?

The drivers come in the drivers/ directory of the Arduino application directory. Once you’ve installed them and rebooted, you should see something like /dev/tty.usb… in the tools > serial port menu when the Arduino is connected to the computer.

The ports named “com1”, etc. are only used on Windows.

Yeah ive tried it several times. Still no luck Its really annoying me now!!! AHH
