How to upgrade Memory.
Mac Retina 4K, 21 5 inch, 2017 Memory/Ram UpGrade 32GB OWC MEMORTY UPGRADE KIT...
Another HiGrade UpGrade.....
My wife bought this floor model and it only had 8GB of memory...so it was slow... So I decided, I was going to fix it....Apple stated the memory was soldered in and it could not be upgraded....which is a lie.

Get the upgrade kit. It has everything you need including the tools.
