    Does anyone know how Yosemite is on mainly Memory? is it worse or better than Mavericks? Or can we not tell properly from a beta?

    Is it, can you explain why. Im new to Macs. My main reason for asking is that I have just bought a Macbook air with 4gig of ram. I was wondering if it will be ok to update to Yosemite when it is out, or will I want to stick to Mavericks.

    Cheers

    Let me put it this way: if you computer has no problems with Mavericks, it will have no problems with Yosemite. It might actually do better, but don't quote me on that.

    Developer builds might use more memory. So you wont be seeing many comparisons until it is released.

    It may or may not run better for you. More so depends on the apps you use and how they perform on the OS.

    In general it should work the same or better but there are so many factors in modern day computing that nobody can really say exactly how it will perform for you without you trying it out yourself.

    Also it's a beta.

    Same for me using Yosemite PB 2 except after coming out of sleep mode (5.33 GB), I see a % more memory being used until I restart the system than it goes back down below 3.7 GB. (<< so I thought. See edit)

    Edit: OK, now I have done a few restarts thinking the memory usage would return to about 3.7 GB in Activity Monitor, but no, it is about 2 GB more than Mavericks with the very same site (This one)..My mistake

    1. Mavericks about 3.7 GB

    2. Yosemite about 5.33 + GB

    Glad I got 8GB of main memory now

    Upgrading OS X has never resulted in my system using fewer resources. New features often result in extra processes and daemons running in the background. After a restart of 10.6 Snow Leopard, my machine would have about 30-40 processes running in the background. Now in Yosemite PB2, I have 184 processes running in the background after a fresh restart with Mail and iStat Menus launching at startup.

    The aggressive caching that OS X does nowadays really takes its toll on a machine with a spinning disk, causing my new machine to feel a little more sluggish than my old Core2Duo MacBook. With the much faster read/write speeds of a machine with an SSD, such as your MBA, you'll see less of an impact. My new SSD and ram upgrade should arrive in the next couple of days, and I can't wait.

    With all of that said, I see little difference in the way my machine runs, particularly the ram pressure and usage, in Mavericks or Yosemite. I imagine that by the time Yosemite reaches its production release, resource usage will see at least slight improvement over the beta releases.

    If you machine handles Mavericks to your liking, Yosemite will likely be just fine for you as well.

    Excellent, thanks for all the responses. I only use basic stuff so I'm sure it will be fine then. Looking forward to it.
