    My Retina Macbook Pro is extremely slow waking up from sleep. Takes about 15-20 seconds to do so. It's not RAM related as it even happens when I'm only using 20% of my 16 GB. I reset the PRAM/VRAM already to no avail. Any suggestions as to what could be wrong?

    Thanks. Did you try setting your hibernate mode to 0, and if so, with what result? Do you know what this does, i.e. write more RAM to disk or less?

    It takes a little bit of time to wake from sleep after it has been sleeping for a little while, but it's not enough of an issue to make me modify the hibernate settings which Apple put there for a reason. I'm not going to mess with that stuff, you have to ask yourself why it was put there in the first place.

    The other question to ask yourself is whether this is even something to be concerned about. This will most likely be addressed with a software update, but how is this even an issue for anyone?

    If you have 16 GB of RAM and the Sleep mode becomes a Hibernate after some period of time, then your computer will copy many GB of data from SSD to RAM on wakeup, which will take some time.

    I previously had hibernate set to 0 so I never noticed this. But with the 10.8.2 update hibernate setting is now ignored by the OS - or, rather, overridden by the "standby" setting

    For a fix see here:

    In short, OS X now has a "standby" mode which hibernates the computer after an hour of sleep. This sucks. But the standby delay can be configured, the fix above sets it to 24 hours which would work for me.

    Waking from hibernate takes a very long time, obviously.

    Here's the command to set standby to 24 hours (as per the above):

    sudo pmset -a standbydelay 86400
