I have been a Windows user for probably all my life, but started using Mac a few years ago. While I never required to use an external mouse with my Mac earlier on, I did find the need for one when I started using the Mac for longer periods.
On Windows, a mouse with a scroller will scroll the page in the direction the mouse wheel is scrolled, for example; the page will scroll down when you scroll the mouse wheel downwards and vice versa. However, Apple uses something called as natural scrolling direction and scrolls the page in the opposite direction.
If you are someone who is annoyed because of this strange scrolling behavior on a Mac, you can change the settings to make the page scroll in the direction you scroll the mouse wheel in.
To make that change, head over to System Preferences -> Mice and then uncheck the box next to “Move content in the direction of finger movement when scrolling or navigating” (In older Mac OS X versions, this would be the checkbox next to “Natural” scrolling”.
Once you uncheck the box, the page will scroll in the direction of the mouse wheel and not the opposite direction.
I am primarily a Windows 7 user and prefer usually multiple monitors while at work. However, I also work with a Mac Book Pro. While I usually never used the MBP in a multi-monitor setup, I have started doing it now.
One of the problems I have faced with both Windows 7 and Mac OS X in a multi-monitor setup is that the orientation of the monitor is usually left to right by default and this is a pain when you are connecting a laptop to an external monitor and want to move your mouse between monitors.
I had written a post to change dual monitor position for Windows 7 earlier, if you are a Mac OS X user, you can follow the instructions below to do it on a Mac as well.
Step 1: Open Finder and open up the “System Preferences” from under “Applications”
Step 2: Click on the “Display” option under in the System Preferences window. This will pop up the display options window on all the multi-monitor.
Step 3: Now on the main monitor, click on the “Arrangement” tab and you will see the monitors you have attached to the Mac. Using this screen you can drag and drop the monitor as per your orientation.
That’s it. You can now move your mouse across monitors the way you have set the orientations of the monitor.
