Step-by-Step Guide

Step 1: Prepare Your Workspace

• Shut down your Mac mini completely.
• Unplug all cables and peripherals.
• Place the Mac mini upside down on a clean, flat surface.

Step 2: Create a Gap

• Insert the opening tool between the bottom cover and the chassis. 
• Gently pry up to create a small gap. 
• Keep the opening tool inserted to maintain the gap. 

Step 3: Release the Clips

• Slide the opening pick along the edge to locate the clips. 
• There are four clips, one at each corner. 
• Gently twist the pick to release each clip. 

Step 4: Remove the Bottom Cover

• Carefully lift the bottom cover.
• The cover is connected via a fragile power button cable. 
• Disconnect the cable.

Step 5: Separate the Antenna plate

• Unscrew the eight Torx screws securing the antenna plate.
• Gently pull the inner plate away from the chassis to slide it out
• Lift the inner plate and flip it over the edge of the chassis. Let it rest against the chassis.
  

Step 6: Remove the Fan

• Remove the four screws for the fan.
• Lift the fan out of its recess in the chassis and flip it over to expose its wire and connector.
• Let the fan rest on the chassis and heat sink.

Step 7: Disconnect the fan

• Locate and disconnect the fan carefully.
• Remove the fan.

Step 8: Remove the SSD

• Once fan is removed, you can see the SSD connected near the fan connection
• Using T8 Torx screwdriver, Unscrew and carefully pull the SSD straight out of its slot.
  

Step 9: Install the New SSD

• Align the connector and gently insert the new SSD into the socket.
• Secure it with the same screw you previously removed.

Step 10: Reassemble the Mac mini

• Reconnect the fan cable and reinstall the fan.
• Reinstall the antenna plate and eight screws.
• Reattach the bottom cover by aligning and snapping the clips into place.

Step 11: Restore macOS

• Due to the SSD lacking a storage controller, you’ll need to restore macOS using DFU mode.
• Use a Mac with macOS Ventura and above, install Apple Configurator from App store, and get a USB-C cable.
• Turn off Mac mini M4 and connect it to the second Mac via USB-C (the middle USB-C port when you’re facing the back of the Mac).
• Unplug power, hold Power button, then plug in power while holding for 10 sec, then release (You'll see mac mini appear in Apple Configurator).
• Open Apple Configurator, select Mac mini, right click on mac mini, click Restore, and confirm.

    Wait: Let the process complete, and macOS will be reinstalled. ✅
