Yes it does but it's totally worth it because it is blazzzing fast. I use Safari, Chrome, and Firefox actively.
1. Chrome - fastest, very secure because it updates automatically, beautiful fonts, very user friendly
2. Firefox - very fast, very secure because it is open source, but sometimes you run into a bug here and there (very rare) and need to refresh it
3. Safari - Laptop runs the coolest. Even with 4k video, laptop doesn't heat up too much. Very good for battery life. The only problem is it's the slowest, but it is reliable. Works great. Also, not secure because you have to apply security updates yourself.
