What will this do/how will this be used?
SolidWorks can do curvature continuous fillets since 2015-2017ish - simply choose that option when creating the fillet.
(I'll leave the flamewar on actual contributions of Apple on the topic of curvature continuous curves - let's just say the original motivation behind them was not aesthetics, as anyone ever having driven down a rad/highway with curves will attest to.)
However, it remains a question whether IBM actually used such or simple rounded (circular) fillets in their design, and then it is up to you as a designer to ultimately decide which one to go with, keep tradition or "go with the wind of industry trends" (as anyone ever having used IBM ThinkPads only to be frustrated by the ergonomics and aesthetics of modern Lenovo ThinkPads will attest to).
