Switching from Windows to a MacBook
Moving to macOS is mostly a software question rather than a hardware one. Before you buy, check that every application you depend on has a Mac version or a workable substitute. Specialised accounting, engineering and company-managed software are the usual sticking points, and a good deal of PC gaming has no macOS equivalent at all.
The move itself is something you do yourself, and Apple builds the tool for it. The setup assistant on a new Mac pulls documents, photos and accounts across from a Windows PC over the network, and anything it misses can travel on an external drive or through a cloud service. Back the Windows machine up before you start.
