Hello to the community. I own a mid 2010 13" Macbook Pro (7,1) running 10.10.5 . I am a university student so bying a newer machine isn't an option right now. I am planning to run Ubuntu on VM with some Digital Design software and i really need a memory upgrade from the 4gigs it now has. I need your help in which seller to choose to spent my money. So the facts are: - I am located in Europe, Greece. - The laptop has already an SSD on it. - I thought of the 8 gig option but as i am planning to keep the machine for at least another 2 years, unless sth happens to it, I'm thinking to go for the best as the last upgrade. I use it for programming and general stuff but no games. - I am between the OWC european shop(if someone can confirm its an official additional website) and the Flexx memory seller in UK. - I think OWC is more expensive. Does that mean anything or should i go for the cheapest? I like OWC and they have a greek reseller with so expensive shipping costs.But i sent an email to both the official website(American one) and the european one with some questions and they didn't answer.It's been some days now. That makes me think that if i have a warranty issue i won't find them or i won't be able to change my product. Flexx memory in UK has a reasonable shipping cost and its my alternative. What's your opinion? Any advices? I want to buy these days but i cannot make up my mind.
