I used to work on an arduino UNO several years ago , and i used it frequently till one day the computer broke, so i had to get a new one. Now i have a new computer ( MAC OS X ) and the computer works fine and all, but one issue remains, the computer cant detect the arduino no matter which port i put it in and there is no serial port option that i can change, i know the plug works since there is energy is flowing to the arduino , but the issue is i cant upload any scripts or reset the one i uploaded several years back. I would love some help and i cant manage to make it work , i tried everything i think would fix it but nothing worked. here is here error message:
