I have a 2015 Macbook Pro running OSX El Capitan and just installed 2011 Sketchbook Pro. When I paste a screen shot into the program is comes out reflected. When I try and scroll it jumps around a bit. So I am unable to use smooth scrolling. This never happened on my 2011 Mac.
To start with, go to the "Apple" menu and then, navigate to "System Preferences". Next, tap on "Keyboard" and next, tap on the "Shortcuts" tab. After that, tap on the "Screenshots" option from the left side of the window. Finally, make sure that all options here are check or active.
Regards,
Will
Most likely, your Macbook Pro is having trouble with its images. Try updating your graphics card's drivers or using a different graphics tool that works with El Capitan. Also, if you have any other problems, we suggest that you call Apple Support for more help.
You can reach out to Sketchbook Pro's customer support for further assistance. Provide them with specific details about your problem, including the reflected screenshots and scrolling issues. They may be able to provide more targeted guidance or offer a solution.
