Hi there all. I apologise in advance if this has been asked and answered already. I'm looking to upgrade my MacBook Pro mid 2012 17" and late 2012 13". The 17" is the problem. Official mac site does not list it in its memory upgrade list. I figured I'd try here. The 17" upgrade is a matter of urgency as it's for a music production company I hope to become involved in and running cubase, my vstis are overloading. I'm sitting at 4mb but my understanding is that I can upgrade to 16 if it's a DIY job. As I say, I just need to be sure that I get the right memory. The "crucial" memory for sale seems to be the best option just now, but if anyone has a different opinion please share. As I say, this is a matter of urgency and cost is not an issue just now. I will bump for a quick response, so sorry about that Best, Palmed eldritch.
