What does the top case consist of?
Just curious as I've been heard because of issues with ports, the whole top case needs replacing.
模具型号A1707。于2017年6月上市，这台MacBook Pro的特征为配有Kaby Lake处理器，可升级至2.9GHz、可动态超频至3.9GHz四核英特尔酷睿i7处理器。
Yes. The top case includes a new pair of speakers. I don’t know if this always happens, but my MBP 15” with TouchBar 2017 top case was recently replaced by a new one in a local Apple authorized service provider and it included: new battery, new keyboard, new speakers.
