PScan will not load after upgrade to Catalina on Apple Mac

Went to connect to the car today, and when I clicked on X-Quartz it came up with the notice as per the screen shot.

I have looked up the support feature and the "default shell" is now "zsh"?!
I tried to alter it back to "bash" but that did not work either.

I don't have a Catalina Macbook. I have a Macbook Pro 17 which despite having 8G RAM, an i7, an SSD drive and a GPU will not upgrade past High Sierra :rant:

However I don't think that it matters whether you have bash or zsh. pscan won't care.

Please click into the xterm window that you have.

Please type these commands:-

then tell me what happens

also on my Macbook Pro those exact same commands will also work from the terminal app.

To do it that way
1. Run xquartz
2. Open finder
3. Go Applications
4. Go to Utilities
5. Run Terminal
6. Enter the commands

So sorry for delay, work has been manic.

By trying the code in XQuartz it comes up "no such file"

By trying it in Terminal it says "Library not found"?!

It looks like you typed two commands on the same line.

Type this command
cd /Applications/pscan.uk/

and then press enter

Then type this command
./pscanloader

and then press enter

Doh!
yep.. 
when using the codes as two entries it is back alive.. thanks!
