When you find that some game (such as Super Mario Run) or app requires the root access to your Android device, or it is unable to work because of some service or authorization issues, remember to try a very famous and popular Android app: Lucky Pacher.

Mac OS X 10.5 Leopard first introduced this Quick Look quick file preview feature, which is simple but brings a great convenience to Mac users.

Quick Look is an excellent feature that was introduced by Apple in Mac OS X 10.5, used for quickly viewing (i.e.: previewing) the content of many types of files. This way, user only needs to select a file/folder -> then click space bar to quickly browse its content without opening this file/folder or running its associated program first. Its simplicity and efficiency are recognized and appreciated by many Mac computer users. However, Windows OS does not have and will not add this feature. Fortunately, we can use some third-party applications to accomplish the same function.
