So, i've had the damn update to Civ 5 showing in the app store for a while now, and I can't update it because it tells me I don't have enough free drive space. I'm on a MBA with 128GB (only 7 GB free at the moment). Tis one of the many reasons i'm waiting for the new MBPR to come out.... The old version of Civ 5 says it's 6.72 GB. I'd assume that the new one was a bit bigger. Would it help if I first deleted the old version... then downloaded the new? Because it seems it must be trying to download the full file, prior to trashing the old. I don't know.... but if I trash the old version, I would have almost 14GB free... would think that should be enough...
