This project was something like that, it didn't start well, and it was simple, but when I continued on my way and didn't break the chain, I saw the fantastic progress. I think if something does not start well, it may end well when you do your best. I wrote this project by HTML, CSS, and JS. We have programs like Notes, Calculator, Terminal, VScode, and other apps and features on this website. I want to introduce my project, which I call Mac OS emulator on the Web.
