With this memory I have expanded my Macbook Pro (Mid 2010) from 4GB to 8GB. I wanted especially for memory-intensive applications like Aperture and virtualization (Parallels). But a large performance gain results from the fact that the applications have been started once each start much faster at the second start. By storage reserves, it is also more possible for me on Mac multiple users incl. To let her started applications simultaneously logged.
The store itself was hitherto extremely straightforward and fast. The installation in the Macbook was done in 10 minutes, and is simple for novices thanks.
Sorry but I have received an invoice by e-mail only after repeated requests.
