In most cases, yes. MuMaster is designed for MuOnline private servers, and the best way to confirm compatibility is to try the 24h trial before buying the monthly license.

No, this depends on the server rules. Some communities allow macros, while others do not. Always check the server policy or ask an administrator before using it.

The most common reasons are running the app without administrator rights or using delays that are too fast for your PC or server. Try increasing the keypress and potion delay to a more stable value, and use the delay calculator to fine-tune your setup.
