As we make use of the new OS X El Capitan, we discover small details that make us see that those of Cupertino, in addition to improving the performance of the system, continue to improve the interface, both of the system itself and of the applications it comes with as standard.
In this case we are going to make a short stop in the application iBooks. As you know, it is the application in where all the documents that you want to send to your mobile devices such as iPhone or iPad are managed.
One of the characteristics that iBooks has is that if what you open is a book in ePub format you will be able to modify the attributes of the book, such as the size with which the letter is displayed in it. You can also choose between several forms of display, having the normal mode, the night mode with a black background and a third mode with a sepia background.
These modes were added by Apple so that you could adapt the text to be read to the lighting conditions of the place or simply to your liking when looking at a backlit screen for a long time. Well, with the arrival of OS X El Capitan, the iBook application has been updated and they have added a fourth display mode in which the background of the ePub books may be gray and the letters in white.
It is a new way that for some it will be fine and for others it will not be noticed with the use of the app. What is clear is that Apple wants you to feel as comfortable @ when reading on your Mac since every day this type of device is used more to read class notes, for example, and we need new color profiles that don't strain our vision.
