I downloaded the new v0.5 installer, for which: thanks!

However, the downloaded file "DeepDeck_Installer_mac_intel" does not have any extension and it is unclear what to do with it: double clicking gives a warning that it is not signed properly. A quick click on the Privacy tab helps there. But looking inside it with a text editor shows a binary structure, not a .pkg or .dmg file. But the downloaded file is not executable. I set the execute bits using the terminal, and then was able to run the installer from the terminal. (I trust DeepSea otherwise)

Please fix this. I doubt the user base of DeepDeck has 35 years of unix experience to chmod u+x a file :-)

I got the webserver up & running on 192.168.4.1.

I tried entering my wifi network, but was greeted with an 'Error Code: 0'
'Message: Http failure response for http://null/api/connect: 0 Unknown Error'

I tried this 3 times. UI Version V0.5.4

All the time when the web page was shown, the OLED display showed "Waiting for connection…"
Clicking KEYMAP and MACROS gave the same error.

These errors occurred both in Safari and Chrome.

Update

I should add I am only connected through the website. The dot after 'Test Connection' is red, and clicking the button does not change anything. The Ahuyama refuses to connect to the existing Bluetooth connection.
Removing the Bluetooth connection and pairing again does also not solve the issue: No matter how many times I 'Connect', it never creates a stable connection, something it used to do in the previous iteration of the firmware.

Getting this error right after it flashes the ESP but it's impossible to tell if it is still doing something (it hasn't existed...) so I'll leave it for awhile...
