im having various issues with my current install of Mavericks on my mid 2009 iMac (non unibody). Including the fact that I cannot open the AppStore. I have tried multiple solutions to fix this with no success. I decided to reinstall from recovery by booting to it on startup. When I try to re-install I get a message saying that 'this item is temporarily unavailable'. I have read that this is either due to account issues or a few other issues.
My only remaining option is to do a re-install from a USB drive or dvd. I also cannot do this as I have no way to obtain the boot image due to the fact that I cannot use the AppStore.
Are there any more options available to me other than finding a bootleg copy of the image or installing from a very old version of OSX from the original purchase of the iMac?
