How to connect Apple Vision Pro to Mac

Step 1: Sign Both Devices Into the Same Apple Account

Make sure both your Mac and your Vision Pro are logged into the same Apple account. The account needs to be protected by two-factor authentication (2FA).

Step 2: Turn on iCloud Keychain Syncing

Besides being on the same Apple account, both the Mac and the Vision Pro need to have iCloud Keychain turned on and synced.

On your Mac, go to System Settings > User ID (your ID) > iCloud > Passwords & Keychain, and check Sync this Mac. On the Vision Pro, the setting is under Settings > User ID > iCloud > Passwords and Keychain, and is called Sync this Apple Vision Pro.

Step 3: Enable Handoff and Pointer Sharing

If you want to control both Mac and Vision Pro apps with your trackpad, Handoff and pointer sharing need to be turned on. On the Mac, go to System Settings > General > AirDrop & Handoff and enable Handoff, and then to System Settings > Displays > Advanced and select “Allow your pointer and keyboard to move between any nearby Mac or iPad.” On the Vision Pro, all you have to do is make sure Handoff is enabled in Settings > General > Handoff.

Step 4: Look at Your MacBook and Select the Connect Button

Under ideal circumstances, once everything is set up as described above, the Vision Pro will automatically show a Connect button floating over your Mac when you look at it. This has occasionally worked for me, but I usually have to manually connect the two devices. If you don’t automatically see the Connect button, continue to the next steps.

Step 5: Look Up to Open the Control Center

If you’ve been using your Vision Pro for a while, you probably already know how to access the Control Center. Look toward the top of your vision until a circle with a down arrow (or V) appears. Tap your fingers while looking at it to open the quick settings. Then select the button showing two bars with circles inside them to open the Control Center.

Step 6: Select Mac Virtual Display

The Mac Virtual Display button is the laptop icon behind a Vision Pro. Select it to open a list of nearby compatible Macs.

Step 7: Select Your Mac

Finally, choose your Mac. It will probably be the only one on the list. The Mac Virtual Display connection will open, and your Mac’s screen will appear inside the headset.

Step 8: Start Working

Once connected, the desktop that was previously on your Mac will appear in front of your vision. You can treat it like any other Vision Pro app window and move it around and resize it however you want. You can adjust the resolution of the Mac display in the Mac’s display settings, just as if you were configuring an external monitor.

How to use Apple Carplay

Pairing up

If you have a compatible car and want to connect Carplay wirelessly, get your phone ready. Look for “Settings” > “General” > “CarPlay.” You’ll need to add the car as one of your known devices, so that eventually the car automatically comes up on your list of “My cars”.

To add the car for the first time, turn your Bluetooth toggle off and on and then look for the car to add as one of your connected devices. To set it up initially, look in “Other Devices” at the bottom. Select the car and follow any pairing instructions that pop up.

Plug it in

With a USB cable, it’s pretty straightforward. Plug in your phone from the unlocked home screen and the CarPlay interface should load on the car screen. Your phone will have limited use on the handset itself while it’s connected to the car. For example, when navigating on a map app you can only use the map on the car screen.

Connect in the car

Once you’re connected, you’ll see a home screen that looks like a bigger version of your iPhone home screen with rows of squares with all available apps.

How to screen-mirror an iPhone to a Samsung TV

1. Go to the Settings on your Samsung TV

First, you’ll need to tap the Settings button at the top of your remote to bring up the hovering menu option. Next, use the circle at the top of your remote to move your cursor all the way to the right, where you’ll find the option to choose “All Settings”.

2. Scroll to the General tab

Next up, you’ll need to scroll down to the Connection tab, where you’ll find the Apple AirPlay Settings option that we’ve been seeking from the very start. From there, a black screen will appear with an AirPlay logo and four gray boxes on the right side of the screen, allowing you to toggle AirPlay on or off (it’s on by default), whether to choose a code for logging on, and more.

3. Turn AirPlay on and adjust settings

While there are four gray boxes on the screen, you will only need to adjust the top three settings based on your preference. Turn on AirPlay, and adjust the Require Code and Subtitles and Captioning settings based on your personal preference.

4. Open the app on your iPhone that you want to stream or mirror

The AirPlay logo is a TV with the Wi-Fi logo diagonal across it. When you see that logo on your app, click the button and a drop-down menu will appear where you can select the TV you wish to stream on.

If this is your first time setting up AirPlay on your Samsung TV, it may require a code on your iPhone. If this is the case, once you select the TV from the AirPlay menu, a code will appear on the TV screen prompting you to enter it on your iPhone. Simply input the code and wait a split second while Apple verifies it’s the same as the one displayed on your TV.

How to configure Cisco switch using CLI

Step 1: Use an external emulator such as Telnet or a PuTTY to login to the switch.

  • Connect the switch to the computer by utilizing a console cable that is connected to the console port on the switch and the serial port on the computer.
  • Open puTTY -> under category choose serial -> in “Serial line to connect to” box provide the COM port to which the cable is connected -> configure the serial line transfer settings -> Click “Open
  • Initial command prompt “Switch>” appears on the screen.
  • Type “enable” next to it and press “Enter”(we don’t need any password to enable at this stage).
  • This will take you to the “EXEC” mode, also known as the Global Configuration mode.
  • Go to configure mode using the configure terminal.
  • Input the configuration commands by typing one command per line.

Switch# configure terminal

Step 2: Provide a hostname for the switch to function in a particular network environment

The provided hostname should be unique within the network in order to facilitate easier identification of the switch. It is also advisable to adhere to any naming standards in order to easily categorize the devices with names.

Switch(config)#hostname <switch_name>
Switch(config)#hostname Cisco_switch_x

Step 3: Configure IP address management

To enable remote connectivity to the switch via SSH or Telnet, it is necessary to configure the IP address. Any VLAN can be selected for configuring the IP. Please utilize the following commands:

Switch(config)#interface vlan1
Switch(config-if)#ip address<ipaddress><mask>

Switch(config-if)#ip address

Step 4: Configure an administration password (enable secret password)

Configuring an administrative password for the privileged exec mode is essential to restrict access. Without this password, anyone with console credentials will have the ability to configure the switch.

Switch(config)#enable secret <password>
Switch(config)#enable secret P@$$w0^d

Note: This password will have to be given before entering into config mode once it is configured.

Step 5: Configure and change default switch credentials

Changing the default password of the switch is crucial, as it is widely known. To modify the password for an existing user, follow the commands provided below:

Switch(config)# username admin privilege 15 password <PASSWORD>
Switch(config)# username admin privilege 15 password P@$$w0^d

We can also create a new set of credentials as given above with desired privileges.

Step 6: Configure default gateway

In order to enable remote accessibility of the switch, it is necessary to configure the default gateway. Ensure that the provided default gateway is within the same network as the device (network router IP can be provided as gateway IP).

Switch(config)# ip default-gateway <IP-address>
Switch(config)# ip default-gateway
Switch# show ip route

Step 7: Configure password for console, Telnet, and aux ports

To establish a secure connection, it is essential to restrict access to the switch through all input ports.

For line console, enter below commands,

Switch(config)# line con 0
Switch(config-line)# password p@$$w0^d
Switch(config-line)# login
Switch(config)# exit

For line vty, enter below commands,

Switch(config)# line vty 0 4
Switch(config-line)# password p@$$w0^d
Switch(config-line)# login
Switch(config)# exit

For line aux, enter below commands,

Switch(config)# line aux 0
Switch(config-line)# password p@$$w0^d
Switch(config-line)# login
Switch(config)# exit

Step 8: Configure static route

In the absence of entries in the dynamic routing table or when there is no specific route available, the switches are capable of forwarding packets via the configured static route.

Switch(config)# ip route <dest_IP_address> <mask>
Switch(config)# ip route
Switch# show running-config

Step 9: Configure interface description

We can configure interface description using below commands

Switch(config)#interface fastethernet 0/1
Switch(config-if)#description Development VLAN

Step 10: Set Duplex mode

The duplex mode governs the data transmission between the switches and the endpoint. When set to full duplex, the switch is capable of both sending and receiving data from the endpoint simultaneously.

Switch(config-if)#duplex full

Step 11: Save the configuration

Switch#write memory
Building configuration… [OK]

Create a Linux Virtual Machine

Step 1: Download and Install Ubuntu

To create a Linux VM,download UBUNTU. You can then choose the 32-bit or 64-bit versions depending on your computer’s architecture. In general, 32-bit architecture is faster than a 64-bit equivalent, but 64-bit enables you to assign much more resources to the system. Often, you’ll select 64-bit for its ability to scale. Simply pick the one that meets your needs.

Step 2: Install the VirtualBox

Download VirtualBox and the Oracle VM VirtualBox Extension Pack that comes with it. Go through the install steps and go with the default values when prompted. Provide permissions to your antivirus and firewalls to run VirtualBox. You may also have to select the folder for installing VirtualBox.

Step 3: Create a Virtual Machine 

  • After installing VirtualBox, double-click on the icon to open it.
  • Following this, name your VM according to a corporate naming convention.
  • Next, select Linux in the type and Ubuntu in the version dropdowns. Remember to select 32-bit or 64-bit, based on what you’ve downloaded.

Now, allocate resources for your VM. The Virtual BOX will ask you to select the memory you want to provide for your VM. This can be a bit tricky. Make sure to add enough memory for your VM and at the same time, leave sufficient for your host OS. If you have many VMs, allocate only the minimum needed to run each at first. You can increase as needed later once you know your resource overheads.

Similarly, create a virtual hard drive for your VM. Decide how much hard drive space your VM needs and choose accordingly. Often, the minimum requirement is between 8GB to 15GB.

Next, select VirtualBox Disk Image (VDI) as the hard disk type.

Step 4: Start the Virtual Machine

To start the VM, click the Start button. When starting the first time, you may see some warnings and errors. Disregard them for now, most are logging missing resource information. Next, you’ll be asked whether you want to try or install Ubuntu. Go with the install option and a wizard will take you through the installation process.

On the first screen, select the two checkboxes and click Continue. On the next screen, select the “Erase disk and install Ubuntu” option. This will only erase the contents of the virtual hard drive you created earlier, and it won’t affect the host OS. Click the Install Now button on the bottom right-hand corner.
