How to turn in Yosemite System 7

System 7 - an operating system that was installed on all Mac in the 90s. If you want to experience a sense of nostalgia or just see how the OS looks at a 33 MHz processor computers, we tell you how.

Below is a detailed guide on how to transform the look of OS X Yosemite to System 7.

To begin with, we will deal with colors. As computers at the time were black and white, we need to do the same thing with our futuristic device.

1. Go to System Preferences → Universal Access, and then increase the contrast and decrease transparency.
   
2. Go to System Preferences → General and select Appearance: Graphite Highlight: Graphite.
   
3. Go to System Preferences → Desktop & Screen Saver and click Solid color → Light gray solid as a desktop background and screensaver.
   

With the colors clear. Now let's move to the icon. The network has a lot of packs of icons and OS 8 and OS 9, but we need the System 7. Pak icon for System 7 can be found in this topic forum Macworld.

IMPORTANT: Before breaching the following operations necessarily make a backup copy of the system.

To replace any icon, you need to select an object, for example, a folder, click on it, right click and select Properties. At the top left of the object icon is displayed and all you need to do - is to drag the new icon at the top. A green plus sign icon and automatically replaced.

And finally, do the final touch to the system look just as at a time when Nirvana was in the tops of the charts - change icons of standard applications.

Go to the Finder and press Command + Shift + G. Open entry field of the address, there is:

/System/Library/CoreServices/CoreTypes.bundle/Contents/Resources/

Now we are in the folder, which contains all the standard Mac application icons. To change them, you have to drag the folder to a new icon with the name that you want to replace and confirm the replacement.

The system now looks like this.

The whole process will take you no more than 10 minutes of time and is nothing more than the usual entertainment.
