Enter Split View
Split View requires OS X El Capitan or later, and the steps differ slightly based on which macOS you're using. If these steps don't work, choose Apple menu > System Preferences, click Mission Control, and make sure that “Displays have separate Spaces” is selected.

Smart new features like Sidecar, powerful technologies for developers, and your favorite iPad apps, now on Mac. Even though the Mac is logged in as another user, your VNC session goes to the original account, allowing both of you to use the machine at the same time. When testing, this is seemed to work well, although you have to wonder if there will be problems with system calls from the same programs happening simutaneously.

You can create Aggregate Device to increase the number audio inputs and outputs available at the same time. You can also use an Aggregate Device if your application doesn't support separate input and output devices.
With Logic Pro, GarageBand, and MainStage, you can use a separate device for input and output. For example, you can use a USB microphone for input and the headphone jack of your Mac for output. Some applications not manufactured by Apple don't support separate input and output devices.

Set up an Aggregate Device
When you create an Aggregate Device, make sure to connect all external audio interfaces first.
- From the Finder, choose Go > Utilities. Open the Audio MIDI Setup application.
- Click the Add (+) button on the bottom-left corner in the Audio Devices window and chose Create Aggregate Device.
- A new Aggregate Device appears in the list on the left side of the window. To rename the device, double-click it.
- With the new Aggregate Device selected, enable the checkbox labeled 'Use' on the left side of the Audio Devices window. Do this for each device you want to include in the Aggregate Device. The order in which you check the boxes determines the order of the inputs and outputs in applications like Logic Pro and MainStage. For example, the first box you checked will be inputs one and two, the second box checked will be three and four, and so on.
The list on the right shows the currently connected audio devices and the number of input and output channels for each one.
- To use the clock of a device as the master clock for all the combined devices, choose the device from the Clock Source menu of the Aggregate Device. Choose the device with the most reliable clock.
- If your audio devices all work with word clock, connect them together using a word clock cable. Connect the cable from the device you designated as Clock Source to the input of each other device. Refer to your audio device product documentation for specific details.
- If any of your devices don't work with word clock, select the Drift Correction checkbox for any devices not designated clock master.
Use an Aggregate Device with Apple music creation software
- Open your application.
- Do the following depending on the application you're using:
- For Logic Pro, choose Logic Pro X > Preferences > Audio, then select Devices.
- For GarageBand, choose GarageBand > Preferences > Audio.
- For MainStage, choose MainStage > Preferences > Audio.
- Choose the Aggregate Device from the Output Device pop-up menu. Logic Pro and GarageBand automatically set the Input Device to the match the selected output device, which you can change if you want to use a different input device. In MainStage, you must manually select the input device.
- In Logic Pro and MainStage, click Apply Changes.
GarageBand automatically switches to the new input device.

Same Time Machine
- From the Finder, choose Go > Utilities. Open Audio MIDI Setup.
- Control-click the Aggregate Device in the left column, then choose 'Use this device for sound output' or 'Use this device for sound input.'
