@leonardo-dicaprio As PeterJones pointed out Notepad++ is a Windows native application. However, you can use Wine bottler or even PlayOnMac app (Free) on Mac to install Notepad++ on Mac. I have had the same requirement when I wanted to use Notepad++ on my iMac. So, I ended up making a video tutorial about it. Here is the link. (How to install Notepad++ on Mac). Hope it is helpful.
Few things to consider:
Since it is not a MacOS native app, the user experience will not be as smooth as other Mac apps.
Also, usually on Mac, you have Command key that is used instead of Control key for common keyboard tasks. However, when you are using Notepad++ on Mac using PlayOnMac, you will still be using Windows like keyboard shortcuts. In fact, that is a good thing, since you don’t need to learn new shortcuts. However, it does feel a bit non-intuitive.
So, if you planning to use Notepad++ as your main developer text editor, I would refrain from that on Mac. (also, disclaimer, this video is from my youtube channel on Notepad++).
Hope it helps.
