Each app loads and can be interacted with like a native Mac application. What surprised me was that I could take each one of the windows apps and place it on the Mac dock. Some of Windows apps I wanted to install included MS Excel 2016 (much more robust functionality than Mac version), some woodworking software (not available in Mac version), and Adobe acrobat (standalone windows version). Parallels provided an incredible seamless integration of Windows 10 with the Mac Desktop. The Macbook is a mid 2014 retina display model with Intel I7, Intel GPU, 16 gb memory, and a 1 TB SSD. I installed Windows 10 and Parallels 11 on my Macbook running OSX El Capitan.
