I'm going to write some software on this laptop. But before I start off I need know a few things. How is C++ on Mac? Especially can I use custom C++ libraries on a Mac? If I write something in VBA on Mac, it works in the Windows version of Excel too?
Yes it will work, but you may need to tweak the code a bit. I had some filesystem specific coding in one of my VBA excel macros and needed to make some changes to work on a Mac (it was developed on the windows version)
