So, how a beginner can learn using MacBook Pro or MacBook Air? If you are switching from PC, you need to learn keyboard shortcuts, Spotlight Search, and Finder. I guarantee, in the end, you will know more than 95% of users who have been using Mac for years. All you need is to read this blog and open each link I have to other posts I wrote. I don’t want you to waste a year, so I assembled an absolute minimum you need to know to use Macs efficiently. It took me almost a year to learn basics.

Optical mice were expensive to make, however, and it wasn't until the late 90s that prices had dropped enough for them to come into general use.The advantage of an optical device was that it solved a major issue with the ball mouse, where the ball would pick up dirt, grease, and fluff and gradually lose functionality over time (although they could be cleaned, of course - never a particularly pleasant task!). The optical mouse was developed in around 1980.The ball mouse was such an iconic design, that it dominated the market for many years.

The motion could be converted into electrical pulses signifying direction and speed. The ball could detect movement in any direction thanks to interaction with two rollers that in turn spun wheels.

In 1972 Bill English came up with the design known as the 'Ball Mouse' by replacing Engelbart's wheels with a ball.

plus a couple of two metal wheels that rolled around on the surface that the mouse was placed upon.

The first mouse was invented by Douglas Engelbart in 1964.
