多谢解答，没注意到论坛英文板块已经有相关问题的讨论了，卡巴官方反应还是挺快的，希望苹果下个版本能尽快修复这个问题。

把Kaspersky system extension 选中，然后点击下面的减号，删除这条配置，然后卡巴斯基会重新添加，重新添加后再打开就可以正常使用了，macOS13正式版也有这个问题，而且不仅仅是卡巴有这个问题，其他杀软也一样的，这个解决办法来自eset官方论坛。

i already can buy and download kaspersky basic/standard/plus/premium on USA’s website like this Kaspersky Plus - Advanced Cybersecurity Protection | Kaspersky Kaspersky Plus | Kaspersky i think it’s already a commercial release?

Do you mean that the KTS key cant active Kaspersky plus now? We should wait for release?

i think you can download kaspersky plus and install it, then try to active it by using your kaspersky account. i also want to know if it works.
