Fuck, i think I found the most useless adaptor. It converts standard SODIMM DDR2/DDR3 to be compatible with MacBooks. The thing is, MacBooks use completely standard DDR2/DDR3, and where the RAM is in a macbook, it has narrow height tolerance, since it is next to the battery. So this adaptor, if you want to use your laptop, you cannot use it, and the adaptor literally does nothing, since it is just a riser. - https://www.ebay.com.au/itm/153452314405
