I have a friend with an Early 2015 MacBook Air 13” whose machine is crawling now that it’s upgraded to Mojave. It looks like the 4 GB of RAM is just not really sufficient to run Mojave. Regardless, I’ve offered to install the logic board upgrade if she buys it. My question is, and I think the answer is yes, but I want to double check, can I have her get the 2.2 GHz logic board if the current one is a 1.6? The CPU speed shouldn’t matter, right? Any answers very much appreciated in advance.
No it shouldn’t matter. Ive personally never done this but I did some research on it and it should be fine.
