files (buffers) not reopening

When opening up Macvim the previous session is semi-loaded. That is, the tabs are reopened, but naming of tabs (using Taboo.vim) is lost and for some reason, any open files from the previous sessions are not reopened.
System: OS: OSX Mojave (10.14.4) GVim: Version 8.1.950
