Review on 🖥️ OWC 8GB (2 x 4GB) PC8500 DDR3 1066MHz Memory Upgrade Kit (OWC8566DDR3S8GP) – Compatible with MacBook Pro, MacBook, Mac Mini, and iMac by Marcus Munoz

I bought another brand for $50 which made my computer beep when I updated software. I decided not to keep that brand and stop with the one I was familiar with. I have used Crucial before and OWC is also well known in my book. So far it seems like I have less of a spinning beach ball and I haven't heard the beep yet. I'll update this review if it turns out to be bad, but so far so good. Bought it for a 13" MacBook Pro mid 2010. I replaced the battery, replaced the 250GB HDD with a 1TB SSD. It works about 400% better than where it was. I put an old hard drive in an external drive MBP recognized this immediately. I still get the spinning beach ball, but it appears and disappears from my screen, not all screens. It doesn't bother me too much. Given the age of this computer, I kind of expect that, especially when I'm trying to run LR and PS on it I spent about $200 upgrading this old girl and I'm so glad she's very usable now.
