Unable to install Platformio using VSCode or Atom

Either installation hangs with the “Welcome to PlatformIO” page which includes a “Reconnect” spinning circle. A “Core” version spinning circle and a spinning circle above the word “Loading…”. “Home” on the page shows version 0.2.5. I cannot go father.

I’m on an iMac with OS X 10.11.6. Any help would be appreciated.

I’ve been using atom with PlatformIO on this machine for while and it just stopped working a couple of days ago after an update.

EDIT: Works with 10.12.6. DOES NOT WORK WITH 10.11.6

Please provide an output from a system Terminal

Please open system terminal (not terminal in PIO IDE) and run:

~/.platformio/penv/bin/platformio home

It should open PIO Home in new browser window. Does it work here?

In the terminal:
PlatformIO Plus (https://pioplus.com) v0.10.8

I
/-
–\ PlatformIO Home
/ _-

|[]| [] | http://127.0.0.1:8008

And in the new browser window the same same result as before. Still trying to reconnect.

Could try to open PIO IDE Terminal and type

pio upgrade
pio update

Now, please restart IDE. Does it work now?

Sorry, no it doesn’t. Did a clean out and a complete reinstall with the same result. I’ve moved off the iMac with the problem to a macbook pro which works so it takes me a moment to switch back.
