A few questions...
A) About My Mac > Support - does it still say "Macintosh"?
B) The installer... How do you view the log? Is there still a menubar on the top (mouseover to show it) like traditional OS X installers of years past? Does pressing Command and L still pull up the log window?
C) Does "About Finder" still say "The Macintosh Desktop Experience"? This hasn't been changed since 10.3, and I'm hoping it's still there.
D) Show a screenshot of First Aid in Disk Utility, please.
E) DVD Player... What version does it say? Still 5.5?
A) It says OS X Resources or Mac Resources with several links
B) The log viewer remains if you created a USB thumb. If you update from App Store it will just do run the update as normal.
C) Yes it's still there
D) Ive attached a screenshot as an Attachment, this modal pops up.
E) 5.8
