    Hi guys. Could someone with the 128gb Macbook Pro Retina please tell me how much of the 128gb drive is available for use by the user ie. how much space is left once the OS etc. is installed. Also I'm presuming the figure for the Macbook Air will be very similar?

    Cheers.

    I've got the 256Gb and it says 250Gb... probably won't be that much a difference between the 128 and 256...

    Well, that's weird. I'm pretty sure that the footprint of OS X is larger than that. I recall that the 128GB Air had around 95GB of available space. But then again, that was way back during the reign of Snow Leopard (Late 2010 MBA).

    Regards

    EDIT: I'm running Mavericks on my mid-2010 15" MBP. My System's folder is 5.5GB and Library folder is 2.5GB. System applications should be another GB or so. But I suppose 250GB should be a close estimation.

    I think mg84 meant 250 GB is whats available after its formatted. Then subtract another 10 GB of so for the base system and core app installs.

    Once the drive is formatted it will have about 120GB of usable space. Then a normal OS X install with iWorks and iLife apps added uses about 20GB. So the answer to your question is you will have about 100GB of user space left for your own files/data.

    Right. I forgot the recovery partition. Also, OS X displays data size as decimal, so a 256GB SSD, which is actually 256 billion Bytes or roughly 232 Giga Bytes, remains 256GB.

    So around 4GB for the recovery partition and, as noted above, 20GB for OS X + bundled application suites.

    Recovery partition is 650 mb unless you let Carbon Copy Cloner duplicate it for you then you end up with 784mb.

    That's all? I'm surprised. I was pretty sure that it would be about the size of an OS X install disk/image. Nevertheless, around 100GB would be the answer the OP is looking for.

    It is different than Windows systems that have the entire OS on a hidden partition. All the 650MB recovery partition has is some troubleshooting tools and a utility that allows download of the ~5GB OS from Apple's servers.

    Well colour me surprised. I was clearly misinformed on this topic, having never really used the recovery partition.

    Really probably better off not using it. Apple's servers just plain suck for an internet recovery unless you enjoy looking at a progress screen for literally hours on end. I am on a fiber optic connection and that is what I end up with using it, so I gave up on that idea ever again now just use the usb installer I made if I ever need to reload/rescue a system.

    Well, even if in no need to install OS from scratch, you might want to use it to check and repair your boot disk. Or restore a password.
    They are actually Akamai's servers. I am on fiber too and have never experienced the pain you describe (well I never download new releases within first 24 rush hours obviously). The OS X install image (4..5GB) downloads within minutes.
    But Akamai's distribution network is heavily spread geographically, AFAIK.

    It may be a regional problem where you live. I have always been able to completely saturate my 30Mbps connection with these updates. Heck, I even installed Mavericks on the afternoon it was released and got a full speed download.

    Apparently they could care less about Canada then I'm on 80mbs and lucky if any Apple update uses a tenth of the connection.
