Thanks, that's a nice improvement indeed. Could you please also change the mac version of the script https://github.com/JabRef/jabref/blob/master/buildres/mac/jabrefHost.py and add a short entry to the changelog.

@tobiasdiez Done! Listed the change under Changed, hope thats fine :)

I thought we had changed this already. Great change.
The mac version fails to run with env (it depends where python comes from, system or brew)

I see, I was only able to test it on my mac with Python installed via brew.
Any way to fix it for non-brew systems?

I tried but there were too many error reports.
I'm not sure if there's a way to do it properly

So on mac we still should use !#/usr/bin/python3 ?

The issue was looked at here: JabRef/JabRef-Browser-Extension#177
If it works we should leave the mac one as is

I just confirmed on a brand new Mac.
Using /usr/bin/python3 works, but usr/bin/env python3 would require the XCode command line developer tools.
I'll revert I reverted the changes for macOS and then the PR would be is now ready from my side.

Thanks, and sorry for the misleading suggestion from my side.
