Why couldn’t the external DVD writer be detected by my Mac after its operating system is updated?

Category : Specification / Capacity / Performance

Different versions of Mac operating systems come with different restrictions on external devices. 

Generally speaking, the later the Mac operating system is, the stricter the restrictions will be. 

If you encounter such issues, it is recommended that you use the official Multiport Adapter or an 

MFi-certified Multiport Adapter to connect your Mac to the external DVD writer.
