I've been dealing with issues with Minecraft on my macbook on and off since I purchased it a year ago. The first issues I met were upon opening Minecraft, I would need to click the play button multiple times in order to get to my world list. When I would get into the world, I wasn't able to place anything. The only way i solved this issue was by restarting Minecraft until the mouse responded. Now the more recent problem I have encountered stems from the use of commands. Any time I try to use commands such as /clear or /fill x y z, nothing happens. When I try to drop blocks from my inventory, they disappear into thin air. When i try to save and quit to title, I only get a black screen which i can only get rid of by force quitting Minecraft. because of this, none of my world changes are saved. I have deleted and redownloaded Minecraft several times and have restarted my laptop more times than i can count. Is there something wrong with my laptop? Is there someone I can take my laptop to in person that that help me? Thank you very much in advance.
