Troubleshoot Mouse Issues After Installing McMouser

Expected Behavior After Installation

Once McMouser Mod is active, you should notice:

• Shift + Scroll now changes hotbar slots smoothly
• Right-click feels immediate and responsive
• No accidental Ctrl key interference during gameplay
• Consistent mouse behavior with Windows/Linux players

If Issues Persist

Shift + Scroll still not working:

• Verify the mod is loaded (check your mod list in-game)
• Restart Minecraft completely
• Confirm you're holding Shift *before* scrolling

Mouse feels laggy or unresponsive:

• Check your Minecraft graphics settings—lower render distance or disable fancy graphics if needed
• Ensure your mouse driver is up to date (System Preferences → Trackpad or mouse settings)
• Try disconnecting and reconnecting your mouse

Right-click behaves strangely:

• The mod disables Ctrl + Click emulation; if you need Ctrl functionality, use your keyboard separately
• Test with a different mouse or trackpad to isolate hardware issues

If problems continue, verify you have the correct architecture version installed for your Mac.
