The filing simply mentions a “portable personal computer,” so there’s no telling which MacBook is getting an update. Apple usually holds events in early spring where the company unveils new products, so a new MacBook being announced in a few months makes sense. Some consumers are likely holding out on buying a new MacBook until the 16-inch model’s improvements hit the more affordable entries in the MacBook lineup, so Apple would be smart to release new ones sooner rather than later. That said, there’s no guarantee as to which updates the new notebooks will actually receive.
