1. 更改电脑名称
要更改在您的网络和 AirDrop 等区域中为您的 Mac 显示的名称，请转到系统偏好设置 → 共享，然后更改电脑名称文本输入字段中的内容。
To alter the name that’s displayed for your Mac on your network and in areas like AirDrop, go to System Preferences → Sharing, and change what’s in the Computer Name text input field.
2. 将音量控制键添加到菜单栏
音量控制可以在 macOS Big Sur 的新控制中心中找到，但有些人更喜欢直接在菜单栏中有一个单独的音量控制按钮以便更快地访问。要将音量快捷方式添加到菜单栏，请从控制中心拖动音量模块，然后在菜单栏上释放它。
Volume controls can be found within the new Control Center in macOS Big Sur, but some people prefer to have a singular volume control button directly in the menu bar for quicker access. To add the volume shortcut to the menu bar, drag the Volume module from Control Center and release it on the menu bar.
3. 从菜单栏中删除spotlight
由于可以使用简单的 ⌘+Space 键盘组合访问 Spotlight 搜索，因此建议从菜单栏中删除 Spotlight 快捷方式，该快捷方式速度较慢且占用空间。要移除 Spotlight，请按住 ⌘ 键，同时将 Spotlight 图标从菜单栏中拖向桌面中间，直到您看到“(x)”图标。
Since you can access Spotlight search with a simple ⌘+Space keyboard combination, I recommend removing the Spotlight shortcut from the menu bar, which is slower, and takes up space. To remove Spotlight, hold the ⌘ key while dragging the Spotlight icon from the menu bar towards the middle of the desktop until you see an ‘(x)’ icon.
4.更换Finder默认显示
macOS 默认在打开新 Finder 窗口时显示“最近”文件夹。要进行更改，请打开 Finder，然后到Finder Preferences → General，然后在New Finder 窗口下的下拉框中选择您选择新的默认界面。
5. 如何在 Finder 中重命名多个文件
首先，选择您要重命名的所有文件（单击往下拉），然后双指点击击它们之后单击重命名 。将出现一个带有各种选项的弹出窗口。您可以选择通过替换当前文件名、在文件名末尾附加文本或根据各种因素（如文件名和日期）重命名文件来重命名文件。弹出窗口的底部是预览，因此您可以查看重命名文件会变成什么名字。
First, select all the files you want to rename (click to scroll down), then double-click on them and click Rename. A pop-up window with various options will appear. You can choose to rename the files by replacing the current file name, appending text to the end of the file name, or renaming the files based on various factors such as file name and date. At the bottom of the pop-up window is a preview, so you can see what the renamed file will be called.
6. 如何将字体样式与内容一起粘贴
粘贴内容时，如果您使用 Option-Shift-Command-V 而不是仅使用 Command-V，则可以将粘贴的内容转换为文档中已存在的内容的样式。例如，如果您有一个斜体文本块，然后想要粘贴来自 Web 的文本并使其也变成斜体，则可以使用此键盘快捷键。
When pasting content, if you use Option-Shift-Command-V instead of just Command-V, you can convert the pasted content to the style of content that already exists in the document. For example, if you have a block of italic text and then want to paste text from the Web and make it italic as well, you can use this keyboard shortcut.
7. 如何快速搜索电脑中的文件
要启动一个方便的搜索界面，在 Mac 上查找文件，只需使用 Command + Space便可以打开Spotlight。Spotlight 可以做各种各样的事情，从定位文件到回答基本问题再到解决数学问题都可以搜索到。
To launch a handy search interface that will let you find files on your Mac, simply use Command + Space. Spotlight can do all sorts of things, from locating files to answering basic questions to solving math problems.
8.如何启用hot corners
Hot corners 可以让您的鼠标移动到显示器的四个角之一时执行特定操作， 比如让电脑进入睡眠模式，锁定屏幕等。启用hot corners 的步骤：系统偏好设置->任务控制->触发角。
Hot corners allow you to perform specific actions when your mouse is moved to one of the four corners of the monitor, such as putting the computer into sleep mode, locking the screen, etc. To enable Hot Corners, go to System Preferences → Mission Control → Hot Corners, and configure one or more of the four corners via the dropdown boxes.
macOS defaults to show the Recents folder whenever opening up a new Finder window. To make a change, open Finder, and go to Finder Preferences → General, and in the dropdown box under New Finder windows show select your destination of choice.
