在多台Mac上开发iPhone应用程序
这可能是非常愚蠢的，但是我可以使用具有不同开发配置文件的多台Mac来制作应用吗？如果我带着我朋友的旅行Macbook，谁也是开发人员并拥有自己的开发资料，我可以使用我自己的开发人员资料来处理我的应用程序而不会干扰他吗？谢谢。
This is probably super dumb, but can I use multiple Macs with different development profiles to make apps? If I take my friend's Macbook on travel, who also is a developer and has his own development profile, can I use my own developer profile on it to work on my apps without interfering with his? Thanks.
您可以在多台Mac上共享一个项目（每台Mac都有自己的签名身份，或者共享相同的Keychain如果它们都属于您的项目。）
You can share a single project on multiple Macs (each one having their own signing identity, or sharing the same Keychain items if they're both yours).
您还可以使用一台Mac来处理多个签名身份。
You can also use a single Mac to work with multiple signing identities.
我同时注册了两家开发iOS应用程序的公司;在他们两个我们至少有2个开发人员拥有我们自己的机器。
I do both regurlarly as I'm enrolled in two companies that develop iOS apps; in both of them we're at least 2 developers having our own machines.
对于你来说，如果你借用朋友的Mac，我强烈建议克隆你的钥匙串的私钥和证书进入这个新Mac，你将创建一个新的用户帐户，然后在你还给它时删除这个用户帐户。
For your part, if you're borrowing a friend's Mac, I highly recommend to clone your Keychain's private key and certificates into this "new" Mac where you'll create a new user account, then delete this user account when you'll give it back.
