Aha, thanks for support! It's nice to hear responses as it's my first time using hacker news, learn about here from friend posting his MacOS simulating(https://news.ycombinator.com/item?id=27084995 https://news.ycombinator.com/item?id=27084995), I've been concerned about whether my posting meets the rules XD.
