I've been running this RAM on my MacBook Pro 17\" without issue for 3 weeks. the performance seems good. I run Windows 7 in Parallels (v6) and bought this RAM so that both MAC and Windows could each run on 4gb. I've run memory intensive apps in both environments and I've received no kernal warnings as some other reviewers have experienced. Thus far it's been a great upgrade.
Positive Review
