These results were soon replicated by others, including our own CNET Labs testing. YouTube tech personality Dave Lee first brought the issue to public attention with a video in which he demonstrated the heat and throttling issues. Secondly, there was the speed throttling issue that emerged just days after the July 12 announcement: Some of the most gung-ho early adopters who ran out and got Core i9 MacBook Pros as soon as they were released found mysteriously throttled performance. First, there was confusion over that keyboard: Apple maintained that the new third-gen butterfly keyboard was quieter but otherwise unchanged - but a teardown at repair site iFixit revealed a totally new membrane that may well address the issue of sticky and dust-afflicted keys on earlier models that have prompted class action lawsuits against Apple. To say things got off to a rocky start is putting it mildly. If anything, the expensive add-on option for one of Intel's new six-core Core i9 processors would appeal to pro-level users, such as video editors and 3D artists, who may be starting to feel that Apple isn't keeping up with their ever-expanding needs for high-end gear. At the same time, the slim unibody aluminum design would remain unchanged since its last design overhaul in late 2016, keeping features both loved (the giant track pad) and not-so-loved (the slim-travel keyboard, the USB-C-only connections). Apple's 13-inch and 15-inch Touch Bar MacBook Pro models would get new eighth-gen Intel processors, more storage and RAM options, a color-temperature-sensing True Tone screen and other tweaks - all nice improvements over a ho-hum 2017 update. On paper, it looked like an impressive, if predictable, set of internal component upgrades.
