how to open secureCRT default in mac

[winnioe]

Hello

everytime I click the node for telnet session on Chrome. I got asked to open telnet using secureCRT in Chrome

after I delete all setting in chrome, I have this problem, It's not a big problem but when I practice CCIE lab, I have to click 2 times for each node(one for node, one for confirming open telnet session using secureCRT), so It's little annoying and make me waste the time. someone knows how to deal with this problem?

Thanks in advance
