Recently, there has been great progress in web fonts. The font family system was introduced in nearly 2015 and many browsers started supporting it in 2017. But now it is widely supported all over the world by web browsers. About 2 years ago from 2020, it is very common to see its use. System font stacks include web fonts like Google fonts and adobe fonts, web-safe fonts which are old and outdated, and self-hosted fonts and system fonts. System fonts are the only ones that require no downloading while all types of font stacks other than system fonts require some downloading.

If you are facing problems with the Apple system like the Apple system is not downloading apps, shows problems with apple map or iCloud is not working the first thing you have to do is to visit its website. Because the reason for the problem might be an outage on Apple's end. If the problem is this then you have to do nothing but wait because Apple will fix it itself. Otherwise, you should start troubleshooting on your end.
