I think it still holds up if you work anywhere with a heavy Mac setup. Schools, design studios, and creative agencies keep asking for it because Apple gear keeps showing up more in offices now. On its own, it will not land you a job, but paired with actual troubleshooting experience, it makes a resume stand out fast.
The exam covers a wide mix of topics, from macOS settings to hardware issues to basic networking, so do not expect a narrow test. One thing that helped me was practicing with real scenario-style questions instead of just memorizing definitions, since that is closer to what you actually see on exam day.
