Machines is an Authorised Service Center. This means they have specific outlets that can check your device, warranty eligibility, and repair drop off/collection. For example, Curve and 1Utama outlets.

You need to make an appointment, through the https://support.apple.com website or the app which is much easier in my opinion!
