transfer data from one to another

Copying data from one Mac to another when the source Mac's screen is not working can be challenging, but it's still possible using a few different methods. Here's a step-by-step guide:

**Requirements:**

1. Both Macs must be running and operational (the source Mac with the non-working screen and the destination Mac).

2. Both Macs should be connected to the same Wi-Fi network.

**Method 1: Using Target Disk Mode**

1. **Shut down** both Macs.

2. **Connect** the two Macs using a Thunderbolt, FireWire, or USB-C cable, depending on the ports available on your Macs.

3. **Turn on** the source Mac while holding down the **T key**. This will boot the source Mac into **Target Disk Mode**.

4. The source Mac's hard drive will now appear as an external drive on the destination Mac.

5. **Open Finder** on the destination Mac. You should see the source Mac's drive listed in the sidebar under "Devices."

6. You can now **browse** the source Mac's hard drive and **copy** the data you need to the destination Mac.

**Method 2: Using iCloud**

If you had enabled iCloud backup on the source Mac, you might be able to retrieve your data without needing to physically connect the two Macs.

1. **Turn on** the destination Mac and connect it to the internet.

2. **Log in** to the same iCloud account that was used on the source Mac.

3. Go to **System Preferences > Apple ID** on the destination Mac and make sure **iCloud Drive** is checked.

4. Your files and data that were synced with iCloud should automatically start downloading to the destination Mac.

**Method 3: Using Time Machine Backup**

If you had set up Time Machine backups on the source Mac, you can use this method.

1. **Connect an external hard drive** to the destination Mac if you haven't already.

2. **Turn on** the destination Mac.

3. Go to **Applications > Utilities** and open **Migration Assistant**.

4. Follow the prompts in Migration Assistant to **restore** the source Mac's data from the Time Machine backup. When prompted, connect the Time Machine backup drive.

5. Select the **specific backup date** you want to restore from.

6. Choose the data and settings you want to restore, and let the process complete.

These methods should help you copy data from a Mac with a non-working screen to another Mac. Make sure to safeguard your data regularly to avoid such situations in the future by using methods like Time Machine backups or cloud storage solutions.
