Override Finders maximum icon size

If you really want to jazz up your finder and “supersize” your icons, open your terminal and enter the following command:

defaults write com.apple.finder DesktopViewOptions -dict IconSize -integer 128; killall Finder

Replace 128 with the size in pixels you’d like to set as maximum as high as 512, but becareful not to push the limits of your hardware as it can be very taxing on your system so proceed with caution
