现象：安装应用后，打开时提示“XXX已损坏，打不开。您应将它移到废纸篓”
如果方法1不生效，可以尝试方法2.
方法1:
执行如下命令，在“系统偏好设置” – “安全性与隐私”的选项“允许从以下位置下载的App”中选中“任何来源”，并再次尝试打开安装的应用。
sudo spctl --master-disable方法2:
控制台输入以下代码，后面加上空格，然后在“应用程序”中找到有问题的应用，拖到终端窗口中，回车运行该命令。然后再次尝试打开应用。
sudo xattr -r -d com.apple.quarantine 原服务器到期，续费太贵，新购一个，迁移成功。记之

()表示捕获分组，()会把每个分组里的匹配的值保存起来，使用$n(n是一个数字，表示第n个捕获组的内容),或者用(<groupname>)来给分组取个名字。
(?:)表示非捕获分组，和捕获分组唯一的区别在于，非捕获分组匹配的值不会保存起来https://github.com/soimort/you-get
The following dependencies are necessary:
The official release of you-get is distributed on PyPI, and can be installed easily from a PyPI mirror via the pippackage manager. Note that you must use the Python 3 version of pip:
$ pip3 install you-get
Add the following line to your .zshrc:
antigen bundle soimort/you-get
You may either download the stable (identical with the latest release on PyPI) or the develop (more hotfixes, unstable features) branch of you-get. Unzip it, and put the directory containing the you-get script into your PATH.
Alternatively, run
$ [sudo] python3 setup.py install
Or
$ python3 setup.py install --user
to install you-get to a permanent path.
This is the recommended way for all developers, even if you don’t often code in Python.
$ git clone git://github.com/soimort/you-get.git
Then put the cloned directory into your PATH, or run ./setup.py install to install you-get to a permanent path.
You can install you-get easily via:
$ brew install you-get
You can install you-get easily via:
# pkg install you-get
Completion definitions for Bash, Fish and Zsh can be found in contrib/completion. Please consult your shell’s manual for how to take advantage of them.
Based on which option you chose to install you-get, you may upgrade it via:
$ pip3 install --upgrade you-get
or download the latest release via:
$ you-get https://github.com/soimort/you-get/archive/master.zip
In order to get the latest develop branch without messing up the PIP, you can try:
$ pip3 install --upgrade git+https://github.com/soimort/you-get@develop
When you get a video of interest, you might want to use the --info/-i option to see all available quality and formats:
$ you-get -i 'https://www.youtube.com/watch?v=jNQXAC9IVRw'

By default, the one on the top is the one you will get. If that looks cool to you, download it:

(If a YouTube video has any closed captions, they will be downloaded together with the video file, in SubRip subtitle format.)
Or, if you prefer another format (mp4), just use whatever the option you-get shows to you:
$ you-get --itag=18 'https://www.youtube.com/watch?v=jNQXAC9IVRw'
Note:
ffmpeg is a required dependency, for downloading and joining videos streamed in multiple parts (e.g. on some sites like Youku), and for YouTube videos of 1080p or high resolution.you-get to join video parts after downloading them, use the --no-merge/-n option.If you already have the URL of the exact resource you want, you can download it directly with:

Note:
You can pass literally anything to you-get. If it isn’t a valid URL, you-get will do a Google search and download the most relevant video for you. (It might not be exactly the thing you wish to see, but still very likely.)
$ you-get "Richard Stallman eats"
You may use Ctrl+C to interrupt a download.
A temporary .download file is kept in the output directory. Next time you run you-get with the same arguments, the download progress will resume from the last session. In case the file is completely downloaded (the temporary .download extension is gone), you-get will just skip the download.
To enforce re-downloading, use the --force/-f option. (Warning: doing so will overwrite any existing file or temporary file with the same name!)
Use the --output-dir/-o option to set the path, and --output-filename/-O to set the name of the downloaded file:
$ you-get -o ~/Videos -O zoo.webm 'https://www.youtube.com/watch?v=jNQXAC9IVRw'
Tips:
You may specify an HTTP proxy for you-get to use, via the --http-proxy/-x option:
$ you-get -x 127.0.0.1:8087 'https://www.youtube.com/watch?v=jNQXAC9IVRw'
However, the system proxy setting (i.e. the environment variable http_proxy) is applied by default. To disable any proxy, use the --no-proxy option.
Tips:
you-get with proxychains and set alias you-get="proxychains -q you-get" (in Bash).--extractor-proxy/-y.Use the --player/-p option to feed the video into your media player of choice, e.g. mpv or vlc, instead of downloading it:
$ you-get -p vlc 'https://www.youtube.com/watch?v=jNQXAC9IVRw'
Or, if you prefer to watch the video in a browser, just without ads or comment section:
$ you-get -p chromium 'https://www.youtube.com/watch?v=jNQXAC9IVRw'Tips:
-p option to start another download manager, e.g., you-get -p uget-gtk 'https://www.youtube.com/watch?v=jNQXAC9IVRw', though they may not play together very well.Not all videos are publicly available to anyone. If you need to log in your account to access something (e.g., a private video), it would be unavoidable to feed the browser cookies to you-get via the --cookies/-c option.
Note:
cookies.sqlite and Netscape cookies.txt.Use --url/-u to get a list of downloadable resource URLs extracted from the page. Use --json to get an abstract of extracted data in the JSON format.
