POD code fails on older MacOS (possible TLS1.2 requirement issue)

[jubilatious1]

Hello, I tried running the POD code below with a fresh install of Rakudo_2020.10 on an older MacOS.

use IO::Socket::SSL;
    my $ssl = IO::Socket::SSL.new(:host<github.com>, :port(443));
    my $content = Buf.new;
    $ssl.print("GET /\r\n\r\n");
    while my $read = $ssl.recv {
        $content ~= $read;
    }
    say $content;

The code hangs with an SSL error, which I surmise has to do with a TLS1.2 requirement at http://github.com. I don't know if I can set an OS environment variable to overcome this issue, or whether the IO::SOCKET::SSL module in various other iterations (Perl5, etc.) accepts a TLS parameter.

user@mbook:~$ raku sergot_PODcode_IO-Socket-SSL.p6 
err code: 336032814
error:1407742E:SSL routines:SSL23_GET_SERVER_HELLO:tlsv1 alert protocol version

Of course, it's unreasonable to expect that Raku modules support ancient OS versions, but it is useful for new users to know they can try out the Raku programming language with a reasonable expectation of success without running the 'latest-and-greatest' hardware. Thank you.
