My internet connection is lame and the last time I tried to update with the download through App store, it downloaded and restarted but said that the
verification of the update package was unsuccessful . I don't want to do that again .
So, I have manually downloaded the update package (1.55 GB) from http://supportdownload.apple.com. Now how do I update Mac OS , and also I don't want the verification failed kind of error. I also do know that this happens at some cases when OSx needs to be installed through the recovery section and you sure can fix it changing the systems date, but how do I do it in this case?
