I am currently in the process of installing MAC OS Mojave with help of an adapter on a 512GB Intel SSD 6.
I tried the Inland 512GB (The high speed one) before this, it worked (not really), sometimes my laptop just failed to boot and was running a bit slow.
Will update after a few days how this settles.
I have an early 2014 Macbook Air model: A1466.
I used the adapter below:
