Mac side crash, high node latency when connected

The latency rate goes up and down, loading is particularly slow, and it's a pain to use. I was using Geph as a backup, but it wasn't this slow before with the free version? Is it a Mac problem? I can't even upload screenshots.
延迟率忽高忽低,加载特别特别慢,用着特别痛苦。本来拿迷雾通当备用的,之前用免费版也没这么慢啊?是Mac端问题吗??截图都传不上来。。

太垃圾了,mac根本用不了。白瞎了我30块钱。。
Unable to use on Mac, a rubbish VPN.
