如果您的Mac是您的主计算机，您会希望能够从另一台计算机远程连接到它(the ability to connect to it remotely from another computer)。即使您不在计算机旁，您也可以访问您的文件和文件夹。
如果您的第二台计算机恰好是Windows计算机，您可以使用SSH协议从您的Windows计算机远程连接到您的Mac 。这在您的两台计算机之间建立了一个非常安全的连接，并让您可以从Windows计算机处理您的(Windows)Mac文件。
为了通过SSH将(SSH)Windows PC 连接到您的Mac，您需要首先在您的Mac上配置一些选项。然后，您就可以从位于世界任何地方的任何Windows计算机连接到您的(Windows)Mac 。
在 Mac 上启用远程登录功能(Enable The Remote Login Feature On Mac)
您的Mac具有一项称为远程登录(Remote Login)的功能，它允许您网络上以及Internet上的其他计算机远程连接到您的Mac并在其上执行任务。为了能够从Windows PC SSH 到您的(Windows)Mac，您需要首先在您的Mac上启用此选项。

How to Remote Connect to Mac from Windows with SSH
If your Mac is your primary computer, you’ll like to have the ability to connect to it remotely from another computer. This gives you access to your files and folders even when you’re away from your machine.
If your second computer happens to be a Windows machine, you can use the SSH protocol to remote connect to your Mac from your Windows computer. This establishes a very secure connection between two of your computers and lets you work on your Mac files from your Windows machine.
In order to connect a Windows PC to your Mac via SSH, you need to first configure a few options on your Mac. Then you’ll be all set to connect to your Mac from any Windows computer located anywhere in the world.
Enable The Remote Login Feature On Mac
Your Mac has a feature called Remote Login that allows other computers on your network as well as on the Internet to remote connect to your Mac and perform tasks on it. To be able to SSH into your Mac from a Windows PC, you need to first enable this option on your Mac.
- Click on the Apple logo at the top-left corner of your screen and select System Preferences.
- On the following screen, find the option that says Sharing and click on it. It’ll open the sharing settings menu for your Mac.
- The screen that opens has several options letting you share the contents of your Mac. Find the option that says Remote Login in the list and put a tick-mark in its box. This will enable the feature on your Mac.
You are now all set to connect to your Mac from your Windows PC over SSH.
The only thing you now need is the IP address of your Mac. If you’ll be connecting from a Windows machine that is on the same network as your Mac, you’ll need the local IP of your Mac. You then don’t need to enable port forwarding on your router.
If you’ll be connecting from a Windows machine that’s not on your home network, you’ll need the global IP of your Mac. In this case, you’ll need to follow the port forwarding instructions given below to access your Mac remotely.
Find The Local IP Of Your Mac
You’ll find your Mac’s local IP on the Sharing pane you accessed previously. If you’ve closed it already, click on the WiFi icon at the top and select Open Network Preferences.
Your IP address should be listed on the following screen.
Find The Global IP Of Your Mac
You can do a simple Google search to find your IP address on the global Internet.
Head over to Google and search for My IP Address.
Google will let you know your public IP address.
Set Up Port Forwarding On Your Router
If you’re going to be remotely connecting to your Mac from a Windows PC far away from your home and not on your local network, you’ll need to forward the port on your router as shown below.
- Open a new tab in your browser, enter 192.168.1.1 in the address bar, and hit Enter. It’ll open your router’s settings page.
- When the page opens, log in using the default login which is admin and admin for both the fields and continue.
- Click on Forwarding at the top to open your forwarding settings page.
- Click on Port Forwarding on the following screen. Enter 22 and 22 in both port fields. Then, enter the local IP of your Mac in the LAN IP field, tick-mark Enable, and click on OK at the bottom.
All the incoming traffic for your IP on port 22 will now be forwarded to your Mac. The reason you used port 22 is because it’s the port that SSH uses for connections.
Remote Connect To Mac with SSH Using PuTTY
PuTTY is a free SSH client available for Windows machines that lets you easily connect to any remote computer over the SSH protocol. This is what you’ll be using to remote connect to your Mac from your Windows computer.
- Head over to the PuTTY website and download and install the app on your PC.
- Launch the app when it’s installed. The main interface shows several fields you can enter values.
- Put your cursor in the Host Name field and type in the IP address of your Mac.
- Ensure the Port field has 22 in it.
- Select the SSH option to ensure you’re connecting using the SSH protocol.
- Finally, click on Open to open a remote connection to your Mac.
- It’ll ask you to enter the username for your Mac. Enter your Mac username and press Enter.
- You’ll be asked for your user account password. Enter the Mac user account password and press Enter.
- If all goes well, you’ll be connected to your Mac from your Windows PC.
Now that you’re connected, you’ll want to know what things you can do with your SSH connection. Here are some of the basic commands you can run to perform actions on your Mac.
View Files And Folders List
To view the files and folders list for your current directory, you can run the following command.
ls
Change The Directory
To change the current directory in your SSH session, use the following command.
