Is it safe to install appium using npm if its appium.app(GUI)is already installed?

Appium.app(GUI) 1.5.3 version is already installed in my mac.
Since new release is out ie 1.6 and I need its GUI version but still its not available

Can anyone please confirm is it safe to install appium using npm/node, if its appium.app(GUI) version is already installed

Or I need to uninstall GUI version first in order to install through node…

it is safe i have both
