I have downloaded TexLive 2015 DVD, and it appears that Linux Commands can be used to install TexLive.
I went to the TexLive website, and they suggest using the MacTex Distribution which agains is a 2 GB + download.
Would it be safe to install from the TeXLive DVD on a MAC?
texbin
stuff, and you might need to add the path manually. But if you know what you are doing, then there should not be any problems
