import httpclient

var client = newHttpClient()
echo client.getContent "http://rosettacode.org/wiki/Rosetta_Code"

On macOS 15 M2, compiled with Nim 2.2.0 (installed via Homebrew):

We still have protSSLv23 as the default, it may have been removed in a newer OpenSSL 3 version installed on macos 15. Try this:

import httpclient, net

var client = newHttpClient(sslContext = newContext(protTLSv1))
echo client.getContent "http://rosettacode.org/wiki/Rosetta_Code"

Perhaps this is specific macOS' OpenSSL issue

import httpclient, net

#var client = newHttpClient()
var client = newHttpClient(sslContext = newContext(protTLSv1))

# error:14004410:SSL routines:CONNECT_CR_SRVR_HELLO:sslv3 alert handshake failure
#echo client.getContent("http://rosettacode.org/wiki/Rosetta_Code")

# OK
#echo client.getContent("https://gcc.gnu.org")

# OK
#echo client.getContent("https://kernel.org")

# error:14004410:SSL routines:CONNECT_CR_SRVR_HELLO:sslv3 alert handshake failure
#echo client.getContent("http://amazon.com")

# OK
#echo client.getContent("http://samsung.com")

# OK
#echo client.getContent("http://quora.com")

# error:14004410:SSL routines:CONNECT_CR_SRVR_HELLO:sslv3 alert handshake failure
#echo client.getContent("https://ebay.com")

# OK
#echo client.getContent("https://edition.cnn.com")

# OK
echo client.getContent("https://www.apple.com")

All works fine on Debian, though.
