In addition, without 3rd party additions running, there is going to be more RAM and CPU available for the task at hand (But I will note, that Safe mode also runs some more conservative device drivers, so things like your video performance may not be normal). This will make sure that there are no 3rd party additions interfering with your Mac (3rd party additions are a very common cause of all kinds of Mac problems). Now boot into Safe mode and try to download the version you really want to install (El Capitan?) via Applications -> App Store -> Purchases If you do not have any of these installers on your system, then it would lead towards network problemsįirst, make sure you have all the Snow Leopard updates _AND_ the special App Store update If you have any of these, then you most likely already have completed the download and your network connection is OK.

Since this happens to you no matter what OS version you try to download, it is either a problem with your Snow Leopard system or a problem with your home network and/or your ISP.ĭo you have Applications -> Install Mac OS X Lion already on your system?ĭo you have Applications -> Install OS X Yosemite already on your system?ĭo you have Applicaitons -> Install OS X El Capitan already on your system? Only Sierra requires you have something newer than Snow Leopard. You should be able to go directly from Snow Leopard to any version up to and including El Capitan. I also tried it on a mac that already had 10.7 and the same happened and also tried it over a different internet connection. Apple are completely useless and are just sending me round in circles to no avail.

I picked back up on it recently and discovered you now have to upgrade from 10.7 which you have to buy via the app store which i did and yet again the same problem. I then tried again with El Capitan in Sept 2016 again then it was FREE and had exactly the same problem.

I contacted apple and they tried a few things via remote viewing but nothing and comms collapsed. For almost 2 years now i have been trying to upgrade the OS on my Mac from 10.6.8 initially it said you could upgrade for FREE to Yosemite which i tried in Nov 2014 it would get a little way into the download and then error the icon would appear in the dock and just say waiting you can restart and go back into Purchases in the app store and click resume and again it would get a little way in and so the same.
