The user, identified on Reddit as UntilHEX, shared Claude's explanation for the overheating, Macworld reported. In the quoted report, Claude said the Mac was running xmrig at about 1,175% CPU, roughly 12 cores, and that the CPU was peaking at 112°C. “Most important: your Mac is running a cryptominer that I didn’t put there. While checking sensor accuracy | saw xmrig using about 1175% CPU, roughly 12 cores. That is why your temperatures are so high, with the CPU peaking at 112°C,” Claude said, according to the quote shared by UntilHEX.

Claude's denial was unprompted, and some Redditors were suspicious of the spontaneous comment, the report said. Redditors had split views on the remark, 9to5Mac reported. 9to5Mac noted that the only thing that seemed to be missing from Claude's comment was the word “totally,” and said the remark seemed more likely to be a training artifact than an AI gone rogue.
