Hello, I want to install the following two font types to my Mac. Could you please let me know their name and where I can download the fonts so that I can use them in the Mac version of Words? Thanks
There's a difference between the Google font and the Google corporate logo. This article explains a bit more (the obvious difference is the slanted 'e') about the 2015 font, known as Google Product Sans.
The font itself does not have an open source license so you do not have the right to install it on your system. That said, there's at least one version that can be download from a third-party site if you use Google to search for "Google Product Sans font."
I did not bother looking for the older corporate font. I will leave that as an exercise to the OP who clearly made zero effort to locate these himself, including this Wikipedia article about the Google logo.
It is worth noting the difference between the Google logo and the font from which it is based. If you look at the older corporate logo, it is three-dimensional, beveled, with shading and highlights. Standard fonts are two dimensional objects and there is no concept of the third dimension (depth), color gradients, lighting nor shading. The older corporate logo was possibly created in a 3D modeling program using the outlines of the two dimensional text as a starting point for creating the 3D models. Or maybe it was done in Illustrator/Photoshop.
