Reviving an Old MacBook Pro (A1502) with Zorin OS 18

Goal

Bring an old MacBook Pro (A1502) that had been sitting in a closet back to life using Linux.

Target Hardware

Item	Details
Model	MacBook Pro (Retina, 13-inch) A1502
Year	2013–2015 models
Processor	4th/5th gen Intel Core i5/i7
RAM	8GB / 16GB DDR3
OS Installed	Zorin OS 18 Core

Background

Dug an A1502 out of the closet
Couldn’t upgrade to the latest macOS; even after a clean install it was sluggish with frequent errors
Gave up on macOS
With Windows 10 support ending and Zorin OS getting a lot of buzz as a replacement, decided to give it a shot

Installation Steps

1. Create a USB Installer

Downloaded the ISO on the MacBook Pro itself and wrote it using macOS’s built-in dd command.

# Check USB devices
diskutil list

# Unmount the USB (e.g. disk2)
diskutil unmountDisk /dev/disk2

# Write the ISO with dd
sudo dd if=Zorin-OS-18-Core.iso of=/dev/rdisk2 bs=4M

Tip: dd shows no progress by default. Press Ctrl + T while it’s running to see the transfer status.

2. Boot the Installer

Restart and hold the Option (Alt) key
Select “EFI Boot” from the boot manager
The Zorin OS installer launches

3. Install

Wiped the entire disk
Dedicated the full SSD to Zorin OS 18
Installation went smoothly
