thank you for replaying。

I've tried using Pingfang as last fallback option，but it doesn't work. then I observed that the Pingfang did not appear in the --system

finally I use Lantinghei to solve this problem.

Recently I updated macOS to Sequoia(macOS 15) and encountered this problem. Then I download the Ping Fang font in Font Book

thanks， the same as you

hitsmaxft commented 3 weeks ago

It seems that PingFang is not installed by default in Sequoia. But I fail to install it in Font book in previous beta, and this bug is fixed in later updates Now Ping Fang works again by downloading from font book
