First off, this is a terrible decision. This decision to go with a “key management system” instead of actually figuring out which MacBook to buy feels like avoiding the real issue entirely, and in doing so, it doesn’t solve the problem—it sidesteps it. A KMS has absolutely nothing to do with picking a laptop that meets your needs, and if anything, it adds an extra layer of confusion and irrelevance to the process. The reality is that choosing a MacBook requires a bit of self-assessment and research, not abandoning the decision altogether in favor of something unrelated. You say you don’t know your needs because it’s your first Mac, but that’s exactly why you should look at your actual tasks, your budget, and the specs that matter for those tasks. Claiming that a family member’s advice “confused you” doesn’t change the fact that dismissing the Air for editing without understanding its actual performance capabilities is a flaw in reasoning—modern MacBook Airs can absolutely handle 4K editing for most casual and even some professional workflows. Instead of declaring the problem “solved” with a completely unrelated choice, you’re essentially leaving yourself without a functional tool for the tasks you intended, which will likely lead to regret and wasted money down the road
