Is this ok to download and should I upgrade to Catalina?

I am trying to open up an excel file and trying to figure out if I need to download several things it is telling me including the attached as well as another font or two? Thanks


Also, should I upgrade?

1. Osaka is a legitimate font and this looks like a legit message. You should be fine agreeing to download.

2. You will need to move to Catalina eventually but it would kill Microsoft Office 2011 if that's the version you're using. That would require you purchase a newer version from Microsoft.
