Last time, I told readers how to properly prepare for the updates. But he does not say a word about what the update to choose for your system, where to get and how to install. Therefore, in today's article I will try to catch up.
At this point, Apple produces three types of updates:
- Software update.
- Delta update.
- Combo update.
Software Update. This is the easiest and fastest way to install because Apple developed for this special tool. It not only automatically checks for new versions of operating systems and standard programs on Apple's site, but also loads them with the subsequent installation. I am sure that you at least once, but faced with this utility. You can find it under "Software Update ..." the main Apple menu.
Delta update - a stand-alone installer that can be downloaded from Forum support Apple's website. It contains the system changes from the time of manufacture of the previous update.
Combo update, In fact, very similar to the Delta update that can be downloaded from the Apple website in Merchant standalone installer. Only apply it possible for any minor version of Mac OS X.
So what do you choose?
There will be appropriate to answer the question of how to choose a method for updating. As I have said, the best option is to check and install the new version through Software Update. In this case, the utility will download only what you need, no more, no less. In all other cases will have to download the file large enough size, which collected "changes and improvements" for all kinds of Apple products.
In addition, if after the transition to Snow Leopard, you do not set any updates, can be downloaded or 3 delta update (10.6.1, 10.6.2 and 10.6.3), or the last combo update 10.6.3 - this is equivalent to the timely System update.
In any case, I wish only successful updates in the future!
