Upgrading from 10.6.8 to Yosemite

Yosemite is more resource intensive than Snow Leopard. If you can install additional RAM, do so. That will tend to lessen any adverse performance tendencies.

The 2 places I’ve seen recommended most to buy reliable RAM are below. I have purchased RAM several times from Other World Computing and have always been very satisfied with the product and service. They have on-line instructions on how to replace the RAM. OWC has also tested RAM above what Apple states is the maximum. I now have 6GB installed on a early 2008 iMac supposedly limited to 4 GB and noticed an improvement.

I have an early 2009 MacBook, 2 GHz Intel Core 2 Duo upgraded to 4GB of Ram, 500GB HD currently on 10.6.8 OS, can Yosemite run on this machine?? I would really like to have contacts and calendars synched w/IMac & Iphone. Why do they leave Mobile Me on the machine when it is not usable?

Yes, your MBP can run Yosemite.

I have the same MacBook with 2 GHz Intel Core 2 Duo upgraded to 4GB of Ram, but when I try to upgrade using app store to Yosemite. I am told that my computer is not compatible. Any ideas?

If it is a model identifier 5.2 Macbook, it should be compatible with Yosemite. Check the model identifier number in System Profiler.
