Remote Desktop- How to Access Your Mac’s Screen from Windows (and Vice-Versa)

Sharing your screen remotely is a convenient way to access another computer as if you’re sitting in front of it. OS X and Windows have this ability built right into them, meaning you can easily share your Mac’s screen with Windows PCs, and vice versa.

Connecting to Windows PC Clients from a Mac

To connect to a Windows PC, you must first turn on remote connections. Open the System Properties and click the “Remote” tab, then make sure “Allow remote connections to this computer” is enabled.

passphrase set up remote desktop

You also want to make sure you install the Microsoft Remote Desktop client on your Mac. It is available in the App Store.

passphrase download the app

Remote Desktop will be installed in your Mac’s Application’s folder. In our example, we’ve already set up a user profile, which is ready for action. Let’s take a moment, however, to click “Edit” and show you what’s involved.

passphrase remote desktop connection

Next to “Connection name” we give it a friendly name while the “PC name” is either the name we gave our target PC or its IP address.

We don’t worry about configuring a gateway because we’re connecting to our PC within our local network. Also, if you do not want to enter your user name and password every time you connect, you can add them to the “Credentials.” Not entering any credentials means that when you connect to your Windows machine, you will need to log into an account.

passphrase pc name and conncetion name

If you want to know what your PC’s name and/or IP address is, you need to check. Use the keyboard shortcut “Windows + R” and then type “cmd” to open a command prompt. In the command prompt, type “ipconfig” and hit “Return.” You want to use the IPv4 address it gives you.

passphrase how to check for your ip address

If you can’t remember what you named your computer, you can find that information on the “System” control panel.

The advantage of using the computer name over an IP address is that the name remains the same unless you change it, whereas IP addresses can change from time to time.

The rest of the Remote Desktop connection’s settings concern resolution, colors, and full screen options.

passphrase view certificate

When you connect to a new client, you’ll likely see a Verify Certificate dialog. Click “Continue” to connect.

If you don’t want to see this warning dialog in the future, click “Show Certificate” and then check the “Always trust …” option as shown below.

passphrase verify certificate

To confirm changes to your certificate trust settings, you will need to enter your system password.

passphrase put in password

Remember, if you didn’t previously enter anything in the connection credentials, you will see the login screen when you first connect. Once you’ve successfully connected to your Windows PC from your Mac, your Windows desktop will appear.

If we want to mess with our Windows 10 test machine, we don’t need to actually be there.

As we mentioned, being able to connect to a Windows machine is a pleasant convenience. For example, your Windows PC may be a super beefy machine you use to do compiling or rendering. You can use remote desktop to check on a job’s progress or start tasks without actually being physically at the machine.

Connecting to a Mac from a Windows PC

Connecting to a Mac from a Windows PC is a little different. You’re not going to be able to use Remote Desktop, but that’s okay because there’s a free client called RealVNC viewer that does the trick nicely.

Just like with Windows, you first have to set up your Mac for screen sharing. Open the “Sharing” preference panel and check the box next to “Screen Sharing.”

passphrase go to computer settings
If you want to edit the name of your computer you can click the “Edit” button. You can leave the “Allow access for:” options as they are.

Click “Computer Settings…” and make sure “VNC viewers may control screen with password” is checked. Then enter a simple password.

passphrase check vnc viewer
The password can be one to eight characters. It doesn’t have to be complicated but at least make it hard to guess.

The VNC Viewer requires installation, but you don’t have to sign up for an account to use it.

Recall from the earlier screenshot that our Mac’s screen can be accessed at or Matt-Air.local. If you’re unsure how to access your Mac, go back to your Sharing preferences and double-check the information on the Screen Sharing settings.

We enter “” in our VNC client and leave the encryption as it is.

passphrase put in your ip address

The RealVNC Viewer application has a plethora of options you can peruse at your leisure. 

You’ll probably be fine leaving them as is, though, if you want your connection to automatically open full screen, you need to tick the box next to “Full screen mode.”

passphrase select option preference
To be honest, we almost never mess with these. Screen sharing from Windows to Mac seems to work just fine as it is.

We return to our connection and click the “Connect” button. An authentication box will appear where you will need to enter the simple password you created in the Sharing preferences on your Mac.

passphrase type in password

When you connect to the target Mac, you will also need to log into a (presumably yours) user account, just like we had to do with Windows (if we didn’t supply our credentials). 

Once logged in, your Mac desktop will now appear in the VNC Viewer window in the same state as you left it.

passphrase go to vnc

If you mouse to the top-middle of the window, you can spawn extra controls, which when you hover will give you a tooltip explaining what each one does.

passphrase customizable toolbar
This little toolbar will let you do stuff like close the connection, go to full-screen, and more. Hover over each button to learn what it does.

You’ll find handy shortcuts to close and save the connection, as well as to change options, and a full-screen button so your shared desktop fills the screen.

On the Mac side of things, a Screen Sharing icon will appear in the menu bar. This lets you quickly and easily access the Screen Sharing preferences or disconnect clients.

passphrase click on screen sharing preference

It’s important to remember that sharing a computer screen is really only suited for short bits of work. If you were trying to remotely repair something or show another user how to do something, it’s ideal, but to get any meaningful work done, not so much. You will always experience a little bit of lag and stutter, and there’s not a whole lot you can do about that.

Like we said, however, it’s not intended for heavy-duty work. Keep in mind also, we’re only sharing our screens locally, which means that if you leave the house, say to go get coffee, and you realize you need to connect to a machine at home, you’ll need to know how to connect to it through your router.
