How to Buy a Discount Mac Computer (6 Steps)

Visit some Apple resellers in your local area and compare their prices to those available in your local Apple Store. Resellers include Mac specialists and warehouses, as well as large electronics stores.
Ask the resellers whether they have any older models in stock. Apple revises the computer specifications regularly, and retailers often discount the previous models to clear space for the latest Macs.
Visit Apple's website and go to the 'Refurbished and Clearance' section. Here, Apple sells off their older models, as well as factory-refurbished Macs. As these have been back through the factory, they are almost like new and come with the Apple warranty. The 'Refurbished and Clearance' link is located under Special Deals on The Apple Store Web page at the bottom of the left panel.
Check online auction websites for your preferred Mac model. Check descriptions fully. If you are tempted to purchase online, check seller feedback.
Compare the discounted Macs you found, considering both prices and specifications. You should also take into account the warranty offered.
Choose your preferred discounted Mac and purchase it. Consider extending the warranty if you see your new Mac as a long-term investment.

How to Create a Desktop Slideshow in Mac OS X

Navigate to your root-level 'Library' folder and open the 'Desktop Pictures' folder. To get to the root-level folder, click on the image of your hard drive in the Finder, usually called 'Macintosh HD,' and click on 'Library.'
Create a new folder in the 'Desktop Pictures' folder and call it 'Desktop Slide Show.'
Select the photographs you want to use and copy them into the new folder created in the previous step. Use the 'Copy' and 'Paste' functions by right or control-clicking the image. If you just drag the photos, you'll end up moving them out from the original folder.
Open the 'System Preferences' by clicking on the Apple logo in the top left.
Select 'Desktop and Screen Saver' in the 'Personal' section of the System Preferences.
Click the 'Desktop' button to go to the Desktop Preferences screen.
Select 'Choose Folder' and navigate to the 'Desktop Pictures' folder you created earlier.
Click the 'Choose' button.
Click the 'Change Picture' checkbox on the bottom left of the 'Desktop' Preferences window.
Choose a duration from the drop-down box next to 'Change Picture.' You can select any duration from 5 seconds to every day, to when you log in or the computer wakes up.
Check the 'Random Order' checkbox if you want the photos in random order, otherwise uncheck it to leave the photos in order.
Quit System Preferences by hitting the Command (aka Apple) Key and Q.
