To disable the trackpad on your Mac

  1. Open up system preferences
  2. Select the section titled “Accessibility”
  3. Scroll down to the Mouse & Trackpad section
  4. In the Mouse & Trackpad section toggle the checkbox titled “ignore built-in trackpad when mouse or wireless trackpad is present”

Flush DNS Cache in Mac OS X

What Is Keychain Access

Keychain Access is where Safari and other applications within the Mac store your passwords and other credentials securely. Storing user credentials poses a risk as malware would be able to access and read your passwords if they were stored as plain text.

In order to counter this risk, Apple created Keychain Access as an intermediary between applications and your passwords. Keychain Access stores all passwords in encrypted form. When an application wishes to access one of your passwords to pre-fill it for your convenience (such as is the case with Safari) it must ask Keychain Access for the value of the given field.

Overall, Keychain Access is simply a gatekeeper / password manager inside your Mac. You should be careful when you delete entries from it as you could potentially delete passwords that you no longer remember.

Macbook Pro Without Retina vs. With Retina

Having used both a retina and a non-retina Mac, I can testify as to the pros and cons of each. The following is a writeup explaining the difference between each screen type.

 

Retina Screen

Pros
  1. Graphics look much sharper
  2. Great for design work aimed at high resolution devices such as the new iPhone with retina display
  3. Better for gamers who want high resolution graphics
Cons
  1. Apps consume more hard drive space since the images are larger
  2. Some websites appear pixelated due to the fact that a web standard has not yet been defined for dealing with multiple resolution displays
  3. Websites that do deal with the retina issue might load slower as bigger graphics must be downloaded to account for the high resolution display
  4. Higher power consumption and less battery life

 

Non-retina Screen

Pros
  1. Graphics look okay
  2. More energy efficient
  3. Smaller apps
Cons
  1. Harder to design for retina screens
  2. Graphics will not render as sharp as on a retina display

 

While graphics do look a lot better in a retina display, most websites and even some apps have still not updated their graphics to work well with retina displays. For example, Microsoft Word looks pretty horrible on a retina display currently. In the case of word, I would much prefer to use it on a non-retina Macbook Pro than on a retina Macbook Pro.
