苹果开发者账号的问题

You have a valid iOS Development certificate in the Member Center, but it is not installed locally. If your signing identity is installed on another Mac, you can export a developer profile on that Mac and import it on this Mac. You can also reset your current certificate. 本人在其他MAC，测试一个项目，出现这个，问一下这个需要怎么弄，重置证书后，会怎样，开发者官网上存储的手机UDID还有吗，有什么后果

解决方案

看上去是说你的证书在另一台电脑上了,你可以从别一台电脑上导出来用,或直接重新弄个证书,这个意思是另一台电脑上的就废了.
重置证书应该是有一些步骤的, 假如需要选择UDID应该会有提示, UDID是对应APPID的吧
