Hello :) I upgraded my macbook 7,1 (MacBook 13.3” Mid-10) with a new SSD. It’s running High Sierra with the EFI 68.0.0.0.0. I decided to upgrade my RAM with both 8Gb RAMs bought here : MacBook 13" Unibody (A1342 Mid 2010) Memory Maxxer RAM Upgrade Kit With both the 8Gb RAMs installed, the MacBook is beeping at booting (1 beep every 5 seconds) and nothing is happening (black screen). However, it’s working with one 8Gb RAM and the original one of 1Gb. Both 8gb RAMs are working separately when paired with the original 1Gb RAM. And the Mac is working and it’s says 9 Gb of RAM installed. I don’t know what to do to solve this problem… since I want to have the 16gb RAM on my MacBook. I read everywhere that it’s working on this model. This other member had the same problem here but it didn’t help : Adding RAM, only boots if one old RAM is in a slot with one new RAM Thank you in advance !

Hello, I just bought another set of RAM from on another seller and it’s working !
Which model do you have? 13” MacBook 2.26 GHz Core 2 Duo (Uni/Late 09)13” MacBook 2.4 GHz Core 2 Duo (Mid-2010) Sadly the 2.26 GHz models PCH can only support 8 GB as the max, whereas the 2.4 GHz models PCH can support 16 GB of RAM.
