I've started 2 help topics about Mac issues and Badspot has replied to both of them. I've also PMed him a couple times to notify him about them. Rather than raging at him about not replying, try to have some patience; he can't reply right after you've made the topic.
If you really want to help, provide the most information you can (run with default Blockland, provide a console.log, etc). Stop expecting things to be perfect and make an attempt to improve things. Yes, Blockland is for mac. Yes, it works on mac. Yes, it may have some flaws. That's why we report them.
