    Hello...

    Wanted to post this and see if anyone has a fix for this issue. I previously had pmset to hibernate =0 which is still the case, however it appears since the Apple 2.0 software update no matter what you set the pmset setting to the sleepimage is still created. This means I constantly have a 16GB sleepimage file sitting on my SSD.

    Has anyone found a fix for this yet?

    Thanks

    Follow the instructions here as a workaround:

    Basically it prevents the sleepimage from getting created because there's a 0-byte file already there which is immutable (meaning the OS can't overwrite it). It will just silently fail when it tries to write the sleepimage. It's not pretty but it works.


    Also do:

    sudo pmset -a standbydelay 86400


    That will force your system to stay in standby mode for 24 hours before going into "hibernate" mode. Remember to shut your computer off if you don't plan on using it for 24 hours! If you don't, then you'll lose any unsaved work after it's sleeping for 24 hours because it won't be able to write the sleepimage.
