Finder is the device management tool included with macOS, serving as Apple's officially recommended solution for iPhone system repair and downgrading. It provides a stable, secure, and risk-free method to

downgrade ios 26 to 18.

Prepare the following tools:

  • Mac computer
  • Original USB cable
  • iOS 18 IPSW firmware for your specific device model
  • Ensure a full data backup is completed beforehand

Step 1: Visit ipsw.me, select your iPhone model, and download the iOS 18 IPSW file.

Step 2: Connect your iPhone to your Mac via cable, open Finder, and select your device.

Step 3: Click Back Up Now to safeguard all your device's data.

Step 4: Disconnect your iPhone and enter Recovery Mode: Press Volume Up → Volume Down → Hold the Side button until the computer icon appears.

Step 5: Reconnect your iPhone to the Mac, hold down the Option key, then click Restore iPhone.

Step 6: Select the downloaded iOS 18 IPSW file and confirm the restore.

Good heavens, I forgot to mention that this solution is best suited for users with macOS Catalina. Simply wait 10–15 minutes, and it will smoothly downgrade ios 26 to 18 while restoring your data.
