How to solve USB 4 device not recognized on MacBook?

1. Insert the USB 4 enclosure into the Thunderbolt port of the Mac device, the LED indicator of the USB 4 enclosure will light up green.

The name of the inserted device will appear on the desktop of the Macbook. When a new SSD is used for the first time, it needs to be formatted in Disk Utility first.

2. If the device does not have a disk at this time, check whether the LED light of the USB 4 enclosure is lit? As long as a good SSD is installed, the light will be on, even if the wrong type of SSD is installed. If the LED light is on at this point, please skip to step 3 below.

If the LED light does not light up, it means that the SSD may not be installed or installed correctly, please refer to the following illustration to reinstall it again. If the LED still does not light up after reinstallation, it may be caused by a defective SSD. Please replace it with another SSD and try again.

3. At this time, the LED is lit, and the device does not come out. You can enter the System information page of the Mac device. Under Hardware, under the Thunderbolt/USB4 option, and under Thunderbolt Bus, under normal circumstances, you will find an Intel-certified device Device Name: Tahini Creek, which means that the USB4 enclosure has been recognized.

At this time, even if there is no SSD installed, just insert the empty USB 4 enclosure, and you will find Device Name: Tahini Creek.

At this point, if the device with Device Name: Tahini Creek cannot be found under the Thunderbolt/USB4 option, it means that the USB 4 Enclosure is not recognized by the MAC device. The following possible solutions:

First: Please check whether the Thunderbolt3 cable in the product accessories is used, and do not use other cables;

Second: Please re-plug and unplug the two ends of the USB 4 Enclosure cable, or change the direction;

Third: Please restart your MAC device and reinsert the USB 4 Enclosure device.

4. In the NVMExpress option under Hardware, you can find a Generic SSD Controller. The following shows the brand, model and capacity of the SSD used in the USB4 enclosure.

In the Storage option under Hardware, you can also find information such as the model and capacity of the SSD used.

5. If the Generic SSD Controller and the used SSD information cannot be found in the NVMExpress option under Hardware, it means that the SSD is not installed or is not an NVMe SSD, which may be an unsupported type such as SATA SSD. 

At this point, you need to check the type of SSD, and select the NVMe SSD supported by the USB4 enclosure for use.

If the above steps have been confirmed and the device cannot be found, please contact Ankmax’s support team directly and describe the problem you encountered in detail, and email support@ankmax.com, we will reply to you as soon as possible.
