I downloaded the latest version of STM32CubeIDE and STM32CubeProgrammer and tried installing it in MAC through Terminal as well as directly clicking on the application. I am getting the message the source cannot be trusted and it is not opening. I am attaching the screenshot for the message I am receiving. Please let me know if there are any followup questions. Thanks ![Screen Shot 2022-01-03 at 12.29.40 PM](https://us1.discourse-cdn.com/flex020/uploads/blues/original/1X/0db704f259aaf058608175026e8656bde8bc8675.png) ---

Hi @samicheen and welcome to the Blues Wireless community! You’ve run into an annoying error that I’ve also seen in the past. There is a terminal command you can run to fix the issue, [documented in this article](https://www.e-tinkers.com/2021/01/how-to-install-stm32cubeide-on-mac-and-stm32-lora-discovery-kit/). ---

Hi, thank you @RobLauer. After allowing the permission it worked. I missed that. Moreover, MAC is not recognizing the Notecarrier device when I am attaching it with USB. I have already attached Notecard to it and its blinking green as suggested in tutorial. Could you please help with this or shall I create a new post? ---

Hi @samicheen, The first thing I would try is a different USB cable. Some USB-A to Micro USB cables are charge-only and don’t support data transfers. If that doesn’t help, let me know! Rob ---

Yea I thought that as well, but could you suggest which one to take? As I have mobile charger cable. Not sure which one to take. ---

Yeah it’s unfortunate that charge-only USB cables even exist! Personally I’ve had good experience with Anker USB cables. If you do a search for something like “USB-A to micro USB data cable” you’ll find plenty of options.
