There are several sources of helpful Macintosh and iOS (iPhone and iPad) tutorials available to you online.
Apple has a series of short tutorials on various subjects. They used to have video tutorials. I don’t see those anymore. Instead, they have short well-illustrated tutorial pages. These are accessible from the Apple Support page.
If you prefer video tutorials, take a look at www.themacu.com . The videos on their Quick Lessons blog are free. There’s a nice list of interesting topics. You can buy their longer tutorials through the App store. Their App is called TMU Tutorials. Macintosh “All Access” is $19.99.
ScreenCastsONLINE has quite a complete collection of thorough Mac and iOS tutorial videos. A subscription to ScreenCasts Online is $21 per quarter.
There is also a free ScreenCastsONLINE YouTube channel with useful tips of the week.
If you watch someone else using an App, you usually have that Aha moment when you think “I could do that!”.� So, take a look at some of these useful tutorials and get more out of your Mac, iPad or iPhone.
