Hi guys,
Please help
Anyone faced this issue?
Please note:
I already went through all the troubleshooting forums for this issue.
I tested my Arduino Uno on a windows system and it works fine
Hi @shazz09. Please try this experiment and then report back with the results:
This procedure is not intended to solve the problem. The purpose is to gather more information.
Now please reply here on the forum thread with the answer to the following question:
Please tell us what you already tried and what the results were when you tried those things.
Thank you for helping me out. 
I tried what you suggested,
Yes the "L" LED blinks multiple times and then goes to a static ON state.
Some other information
I have tried all of these troubleshooting steps
I am not sure if the USB cable is faulty because it worked fine on the Windows system. I got the cable slong with with the Arduino Uno
This tells us that the bootloader required for uploads is present on the primary ATmega328P microcontroller of the UNO board and that the microcontroller is running the bootloader. A missing bootloader or non-functional ATmega328P is one of the potential causes of failed uploads, so this result eliminates those as the cause of the problem you are experiencing.
Which version of Arduino IDE are you using (e.g., "2.0.1")? The version is shown on the window title bar and also in the Help > About dialog.
I ask for this information because I want to give you the appropriate instructions for the IDE version you are using.
thanks for letting me know. I am using Version 2.1.1
OK, I'm going to ask you to post the full verbose output from an upload attempt.

Unfortunately I don't have any other good suggestions for things you can try to fix the problem. The guide you followed covered most of the things I would suggest already.
If you have an ISP programmer or suitable spare Arduino board on hand, you can try burning a fresh copy of the bootloader to the board. I'm not very optimistic about that being a solution though because the blink after you press reset gives some indication that the bootloader is already fine. In case you are interested, there is a tutorial for using a spare Arduino board to burn the bootloader here:
Failing that, I can only conclude that there must be some sort of permanent physical damage to the board. In this case, the best remedy is to buy a new board.
I am waiting for a new board
if there is some sort of permanent physical damage -> why is that it works fine on Windows but not on Mac
Good point! I missed that. Unfortunately I don't have any idea what would cause this. That indicates the bootloader, USB cable, and board are just fine.
Another thing I noted is that the error message is unusual. Normally this one:
avrdude: stk500_recv(): programmer is not responding
Is paired with something like this:
avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0xd3
But in your output the "stk500_getsync()" errors are absent.
I have same problem - it's the M1 Mac and how it handles the USB connection - I too have been through all the items listed. I will use my i5 Mac. You need to use and probably switch to Raspberry Pi if. You think they would have tested this. I too have a very old board - like 10 years I think. Confirmed that works fine with latest 2023 IDE on my i5 Mac intel. Nice one Arduino!
Uploading works fine on my M1 Mac. Here is the output from a successful upload to an official UNO R3 board I did just now:

I do testing for Arduino on my M1 Mac regularly. In fact, the company provided me with that machine specifically for the purpose of ensuring we have testing coverage of that host architecture (I primarily use an x86-based PC).
I do have the same issue on Macpro m3, with various nano board / pro mini board; both with branded or chinese copy; which are all working on a x86-based linux.
The mac is a brand new install
Interestingly, if i do manually rest the baord; i get only one of the 2 errors (as described above) ; but if i do not, i get the usual 2 (with stk500_getsync())

Hi @resttest.
Let's focus on the Nano boards exclusively for now. There are significant differences between the Nano and Pro Mini boards and I think that attempting to troubleshoot both boards simultaneously might lead to confusion.
Please try this experiment and then report back with the results:
This procedure is not intended to solve the problem. The purpose is to gather more information.
Now please reply here on the forum thread with the answers to the following questions:
Hello! I have the same issue with Arduino Uno R3 on M1 Mac. Any ideas on how to fix the problem? The board and cable are OK (working with other PCs). I'm connecting Uno via USB hub (no USB 2.0/3.0 in mac pro)
Hi @puszkaluk. I'm going to ask you to post the full verbose output from an upload attempt.

Failed uploading: uploading error: exit status 1
And what's important Led "L" is blinking properly.
okay, I had an exactly same issue with mine. I also uses 2020 Apple M1 13" and gave me the same problem. Luckily, found a solution. First, change the programmer to ArduinoISP.
Second, try installing this driver: GitHub - adrianmihalko/ch340g-ch34g-ch34x-mac-os-x-driver: CH340G CH34G CH34X Mac OS X driver
that should solve your problem (mine worked at least)
hope it works and have fun
