    Same problem here. Acrobat is displaying a simple 190 pages document and appears to be using 50% of the CPU ressources. After a while the Macbook temperature rises and the fans start. As a solution, instead of using Acrobat as a PDF reader, I use the Preview app from MacOS that consumes almost no CPU. Please have a look at the screen captures attached. All last versions installed (Mojave and Acrobat).

    Hi Ravi,

    Thank you for your help but it didn't work. To display a document at its real size, I had to check «Use system definition» (there, it says 108 dpi instead of 218 dpi, which is the actual definition of my iMac 5K), then ask Acrobat for displaying at 100% scale. This is misleading because the system definition parameter is wrong but I can live with it.

    Here it is. The 5k screen definition is 218 ppi. The Acrobat preferences window shows the wrong definition (108 ppi). When you set this parameter to 218 ppi, the document is displayed bigger than it should. There is a confusion made by Acrobat in the naming of the screen definition (the one that appears in the preferences is the logical definition, not the actual definition).
