I have a Retina macbook Pro late 2012 running OS X High Sierra version 10.13.4. I have decided to upgrade my SSD because 120GB is not enough, therefore, I bought a JetDrive 720 SSD (240GB) from Amazon to perform a DIY upgrade.

It should be pretty straight forward but I am having the following error when I try to clone the original drive into the new drive.

enter image description here

I have followed the instructions from the manufacturer but it simply isn't working. Instructions: Transcend JetDrive 720 Manual

I suspect that the issue is with APFS.

    Using Disk Utility, can you partition and erase the drive?

    I’m currently attempting one option: I’ve downloaded Carbon Copy Cloned software and so far it appears to be cloning the Macintosh HD to the JetDrive. If it doesn’t work i’ll Try to partition.

The solution was to download Carbon Copy Cloner software because apparently Disk Utility and APFS created a bug after High Sierra update. Just connect your JetDrive or any other drive, follow the prompts and press "clone". That should work for everybody.
