Troubleshooting Common Issues: How To Mount 2017 Macbook Pro As External Drive

Sometimes, even with the best laid plans, things can go sideways. Mounting your 2017 MacBook Pro as an external drive is no exception. Let’s delve into the common hiccups you might encounter and how to smooth them out. Consider this your troubleshooting toolkit, ready to tackle those pesky problems head-on.

Drive Not Being Recognized

The most frustrating issue is when your MacBook Pro simply refuses to appear on the other computer. Don’t panic; it’s often a simple fix.

Check the Connection: This sounds obvious, but a loose or faulty cable is the most frequent culprit. Ensure your USB-C cable is firmly plugged into both the MacBook Pro and the host computer. Try a different cable, ideally a Thunderbolt 3 cable, as these offer superior performance and compatibility. If using a USB-C to USB-A adapter, make sure it’s rated for data transfer, not just charging.
Verify the Host Computer’s USB Ports: Some USB ports may not provide enough power or may have issues. Try plugging the cable into different USB ports on the host computer. USB 3.0 or USB 3.1 ports are generally preferable.
Check the Target Disk Mode (TDM) Status: If you’re using Target Disk Mode (hold down the T key during startup), make sure it’s correctly initiated on the 2017 MacBook Pro. The screen should display a Thunderbolt symbol or a floating hard drive icon. If not, restart the MacBook Pro and try again.
Update macOS on the Host Computer: Outdated macOS versions can sometimes cause compatibility issues with external drives. Ensure your host computer is running the latest version of macOS or the most recent updates available.
Inspect the Disk Utility (on the host computer): Open Disk Utility on the host computer. Even if the drive doesn’t appear on the desktop, it might still be visible in Disk Utility. If it appears there, you might need to mount the drive manually. Select the drive and click “Mount” in Disk Utility. If the drive is greyed out or shows an error, there might be a more serious problem.
Firewall or Security Software Interference: Some security software or firewalls on the host computer may block access to external drives. Temporarily disable these to see if it resolves the issue. Remember to re-enable them after testing.
