Problem with uploading code to Arduino mini 05

Hello, i'm quite new in this game and I seem to have bumped into a problem even google can't explain me.

I have previously uploaded the same code to my Arduino Uno with no problem.

Now i would like to upload it to my new Arduino mini 05 using a Arduino USB serial light.

The problem is that i can't seem to choose the correct serial port (/dev/tty.usbmodem1a123.) instead I can only choose from two ports; /dev/cu-bluetooth-moden or /dev/cu.bluetooth-incomming-port

What do i do?

Every answer is appreciated!
