If you are someone still on Snow Leapord who is pondering a move to Lion or someone who has more than one Mac and still have Snow Leapord running on some of your Macs then you may want to install this tool “Scroll Reverser” that will help you set scroll behaviour similar to that of Mac OS X Lion. This tool helps Snow Leapord users to start using and learning the new scroll behaviour and for people with Macs on different versions of Mac OS to unify the scroll behaviour across all Mac machines.
When you install and run Scroll Reverser it’ll add an additional item to your menu bar on the top which will allow you to choose the preferred scroll behaviour. Select “reverse scrolling” from the menu and you’re all done. This will also reverse the horizontal scroll to make it similar to that of Mac OS X Lion.
Having upgraded to Lion (Mac OS X 10.7) I realise that one of the biggest change that initially bothers you and takes some time to get used to is the reverse scroll behaviour that Apple has enabled as default in the new operating system. Like everything else, you get used to it after a couple of days of usage.
You can set scrolling gesture back to what it used to be in Snow Leapord through the preference menu. Personally, I recommend not to reverse the default that comes with Mac OS X Lion but to try and get used to the change. Though it takes some time to get used to, it probably would be worth in the long run. Apple is trying to unify the operating systems (iOS and Mac) and this change is a result of the unification. There is a strong probability that there would be only one OS running on both the desktops and tablets. Even if it doesn’t, Apple is trying to bring in a similar usage experience on both devices so that new users can easily adapt to the OS and easily switch between Apple devices owned by them. It is likely that future changes will be in line with new scroll behaviour and eventually one will have to adapt to the change. It is better to start now then to leave it for later.
