I have a new herelink, and it is needing a Usb firmware upgrade, but I download the upgrade file cmd line tool for firmware update from the current docs, (for mac), and it keeps spitting out this error: Last login: Tue Jun 1 08:46:44 on ttys000 The default interactive shell is now zsh. To update your account to use zsh, please run `chsh -s /bin/zsh`.

I cannot get the firmware updated, as it seems to have a unauthenticated or error setting certificate. i have downloaded it several times to see if it fixes anything, but it is the same. I look forward to your reply! Solomon, UAS Technology Instructor, Lane Community College ---

Have you unzipped the folder? Did you execute the executable without unzipping it? ---

Yes, I unzipped the executable, as you can see with the posted text, it was running, searching for devices, and successfully connected to the devices. But then it runs into a problem with the executable when it tries to run line 77 of the executable… ‘error setting certificate verify locations: CAfile: /usr/local/etc/openssl@1.1/cert.pem CApath: /usr/local/etc/openssl@1.1/certs’ ---

That looks like a pc issue. Please try on another computer. ---

I tried a windows and it worked fine. Perhaps there was something with my computer, or the mac version of the bootloader executable. I got it solved though. Thanks!
