Ya girl just downloaded Java on my MacBook and I have a wireless mouse that works perfectly fine for literally everything else I've used it for. However, I tried playing Minecraft and the left click doesn't work very good? It just doesn't register it despite the mouse clicking. I would've just played using the scroller and adapted but I can't do anything with the touchpad either. I can't move anything in my inventory which makes crafting a no go. The same started going for the mouse. I tried reinstalling and fiddling with settings but nothing is working and I still can't move anything in my inventory.
