Safari closed the game
Safari saysThis webpage was reloaded because it was using too much memory.
The game needs a lot of memory, and Safari on a Mac sometimes closes it to save memory. Google Chrome on the same Mac is the browser the game is tested in most. On iPhone or iPad, see phones and tablets.
Move to Chrome and keep your saves
Saves are kept inside the browser you played in, so bring them along with a backup file:
- In Safari, open nfscrb.xyz. In the Saves panel, press Download backup and keep the file in Downloads.
- Install Google Chrome and open nfscrb.xyz in it.
- In the Saves panel, press Restore from file and pick that file, then press Play.
The first start in Chrome downloads the game files again.
Staying in Safari?
- Close other tabs and other big apps before you play.
- Keep Safari up to date: Apple menu → System Settings → General → Software Update. The game needs Safari 26 or newer.
- If it keeps closing, send a report from the start page the next time it opens (it offers to). It tells us how far the game got.
