Add proper support to MAC OS systems (workarounds do not work)

[GitLad]

Installing 'coreutils' and setting the alias to timeout for gtimeout does not work.

It is missing '--timeout' flag. So the code fails on line 56 or 58 where it specifies --timeout=$TIMEOUT.

I do not want to use PERL workaround as it won't be available on all machines. And the script needs to run on both Mac OS and linux alpine, so I can't simply change it to work with one or the other.

You get what you deserve for using a Mac unironically.

@GitLad can you post that PERL workaround? All the work Macs I've seen have PERL installed

I kinda expected to see a "OS/distribution compatibility table" somewhere.

I also need it to work at least on Ubuntu (works) and MacOS.

Peace.
