This can be useful for when you think files have been corrupted and need to be replaced.
Presumably, the files are simply reinstalled.

The result? The Install utility gave the green light.
#DOWNGRADE MAC OS X TO SNOW LEOPARD UPDATE#
On a related note, I checked what would happen if I attempted to re-run the 10.6.1 Update package on a Mac that had already been updated to 10.6.1.
#DOWNGRADE MAC OS X TO SNOW LEOPARD ARCHIVE#
The only apparent difference between this method and an Archive & Install in Leopard is that there is no residual Previous Systems folder left in Snow Leopard. When you are done with the downgrade, your hard drive will once again be running Mac OS X 10.6.0 (Build 10A432). However, it did not uninstall the iTunes 9 upgrade from the previous day.

For example, it my case, it uninstalled the HP Printer drivers update I had separately added along with 10.6.1. It also appears to remove any Apple updates you installed after 10.6.1. If you simply select to install 10.6 from the DVD, it will do so, smartly replacing the 10.6.1 files with the relevant 10.6 files. In Snow Leopard, this option is no longer available. In Leopard, you did this from the Install DVD via an Archive & Install. The answer is yes, but in a different way than with 10.5.x. In any case, the question is: Can you do it? Why? Perhaps 10.6.1 introduced a compatibility problem with your favorite application.
Moving on, let’s suppose you’ve updated to Mac OS X 10.6.1 and want to return to 10.6.0. You also can’t save multiple packages in one step, as you could with Software Update in Leopard.ĭowngrade to 10.6.0 via Install DVD. In some cases, a given update may not even be on the Downloads page until a day or so after it is available via Software Update, adding to the potential confusion. You now have to locate the desired updates yourself on the Web page. Regardless, the Snow Leopard Software Update option is a bit less convenient than the Leopard method. The About the Mac OS X v.10.6.1 Update article still states “that an update size may vary from computer to computer when installed using Software Update.” This implies that Software Update is still using a delta update, different than the standalone installer. Although delta updates work fine most of the time, the consensus has been that the Combo update is the go-to version if you want to minimize the risk of any problems. In Mac OS X 10.5, all of the Software Update options used the smaller “delta” version. By sending you to the Downloads Page, you presumably get the “combo” version of the update (which combines all previous updates into one package - and is thus not really relevant for a. This new arrangement is not altogether a bad thing. In instead, there is just one new option: Go to Apple Downloads Page, which takes you here. The latter choice combined the two other alternatives, both installing the Update immediately and saving the download package for later. With the former choice, the update package downloaded (typically to your Downloads folder) but did not install - allowing you to install the update at any later time and on any volume you selected even when you were not online. In Leopard (Mac OS X 10.5), Software Update’s Update menu offered two useful alternatives to the default Install option: Download Only and Install And Keep Package. This means that, should you want to install the update again, such as on a second Mac, you’ll need to redownload the update. When you use this method, there is no Update package left on your drive afterwards. And you likely followed the application’s prompts to install it directly: either by clicking Continue in the initial message or by clicking Show Details followed by Install. If you’ve already installed this update, chances are very good that you used the Software Update application to do so. First up is last week’s release of Mac OS X 10.6.1. Update to Mac OS X 10.6.1: Software Update menu change. In particular, I want to shine a light on several troubleshooting-related changes to how Snow Leopard updates, reinstalls and relaunches software. Following up on a prior column, Sweeping Up after Snow Leopard, today’s article continues my floor-level look at Mac OS X 10.6.
