When software update says that your mac is up to date, macos and all of its apps are also up to date. that includes safari , i tunes , books, messages, mail, calendar, photos, and facetime. to automatically install macos updates in the future, including apps downloaded from the app store, select ”automatically keep my mac up to date.”. I got disconnected from the internet halfway through a software update on my os x system, and it didn't delete the incomplete download. i now don't have enough disk space to do the update.. The ipsw on mac location is: ~/library/itunes/iphone software updates . the easiest way to find the ipsw mac location is by going to make sure you have selected finder in your dock (usually the icon on the far left of the dock) hold down the alt key and select go from the menu and then select library..
I started software update over again, and the 420mb update was still cached so i didnt have to go through the pain of downloading again, but it did the same thing, so now i am going to just download it from the apple site and not through software update.. Software update is a free and instant informer special for those users who care to keep their application up-to-date with new functions and better performance.. I ran the updates feature in the app store on my imac today, and it reported both a delta (incremental) update to mountain liion to 10.8.1, and a full download of the 10.8.1 combo (4.37gb). after running the delta update, i decided to download the full combo version, just in case i ever needed to do a full reinstall..
