nostr:npub1p9kjc5uauqdfphar82xmq573tf3hnh3mcugkw3t6mjg2y76xkd3sum865w My Macbook of the same year developed a swollen battery. I had trackpad issues before the swell was obviously visible. Might be worth looking at the palm rest with a straight edge to rule that out. (Maybe swelling can short-out/hold-down a key and cause your issues?)
