Hi Giulio, apologies for delayed response, been a strange time as you know. Thanks so much for your help on this issue.
Yes! Finally, that worked - It appears that the Mac didn't trust the host 192.168.6.2 .
When I ran the ssh root@192.168.6.2
command, here is what came back:
The authenticity of host '192.168.6.2 (192.168.6.2)' can't be established.
ECDSA key fingerprint is SHA256:jTso6q10VYd5/7ZUBCUyEtq7sZg1RA9Jjv86pSMw+BA.
Are you sure you want to continue connecting (yes/no/[fingerprint])?
I responded 'yes', and, problem solved! The IDE is now running successfully in the browser.
As I've been relying on the jumper-cable solution [https://github.com/BelaPlatform/Bela/wiki/Manage-your-SD-card#Booting-problems] until now, I've run the /opt/Bela/bela_flash_emmc.sh
code in the IDE, to update the Bela image on the eMMC.
And finally, the disk image has come up successfully, without the jumper cables, and the IDE is connected
