Sims 3 Update I have a iMac running Snow Leopard 10.6.1, 2.66 Ghz Intel Core 2 Duo. I have "Sims 3" 1.2.7.1 and when I try to apply update it says "Some of the files have been modified. Please Re-Install". In the Log there are three things in red: Contents/Frameworks/wineserver -> SHA1 Error Contents/MacOS/cider ->SHA1 Error Contents/MacOS/cider_noui ->SHA1 Error
Did you by chance swap out the shaders precomp file (censor remover) and/or the resource cfg files? You need to have the original files to apply any patches.
I had a similar problem If it's installed on an an account that's not an administrator then this thread might help. http://forum.thesims3.com/jforum/posts/list/80257.page
I have the Sims 3 installed on my iMac with a non-administrator account and the updates/patches works as they should, but I don't have snow leopard installed. I'm pretty sure swmeek and flameback are correct. Always remove all of your mods folders and files needed for the mods to work before you update anything to have less chances of problems...
