What's New in MFC macOS V4.5

According to the official changelog, MFC macOS Software v4.5 was released on October 10, 2026. The main changes are summarised below.

New device support

iPhone 18 / Duo series
Apple Watch Ultra 4
Apple Watch Series 12
Mac Studio M5 series
Mac mini M5 / M6 series

Diag without a DCSD cable

For the newly supported iPhone, iPad and Apple Watch models, data reading and writing now works through a standard USB Lightning cable. A special DCSD cable is no longer required for these supported Diag operations, which reduces both cost and setup effort.

App management additions

Online App Store search
App installation support
IPA file download support

Users can search for apps and start installation or IPA downloads directly through the software.

Ramdisk improvements

Added support for iPhone X on all iOS 16 versions
A pre-mount check now runs before Ramdisk creation and data recovery
Improved Ramdisk creation process and data recovery stability
For Apple Watch Series 3, 4, 5 and SE (1st Generation): language selection during data recovery, and improved post-recovery operation so supported watches can be used independently without pairing

Other refinements

Improved reading of camera modules, infrared dot matrix and Face ID hardware, better file transfer efficiency, more stable batch transfers, and improved task scheduling during firmware updates and recovery.

It is also worth noting that parallel multi-device workflows were introduced in V4.3.1 (December 17, 2025) through iBUS X support, and these carry forward in V4.5.

Key Features

Multi-device parallel operations – Several Apple devices can be connected and updated or restored together. Each device runs as an independent task, and progress for all devices is visible on one screen through the built-in task manager. As per the release notes, iBUS X is required for parallel workflows.
Firmware update and recovery – The V4.5 release improves task scheduling, process management and stability for both single-device and multi-device firmware operations.
Backup management – Full and unencrypted device backup, smart incremental backup, quick encrypted backup settings and management of multiple backup versions, so you can restore the exact version you need.
File manager – Improved transfer between Apple devices and Mac computers, better file reading and writing efficiency, and more stable batch file transfers.
Detailed device information reading – Reads front and rear camera modules, ultra-wide and telephoto modules, the front infrared dot matrix and the Face ID module, with improved hardware recognition stability.
App Store and IPA support – Search apps online, install them directly or download IPA files. Batch IPA installation without an Apple ID was added in V4.3.1.
Diag operations – Expanded model coverage with standard USB Lightning cable support for the newly added devices.
Ramdisk data recovery – Improved creation process, pre-mount checks and a more stable recovery workflow for supported iPhones, iPads and Apple Watches.

How MFC macOS Works

Based on the release notes, MFC macOS connects Apple devices to a Mac computer and provides the following confirmed functions: reading device and hardware information, updating firmware, restoring systems, managing backups, transferring files, searching and installing apps, downloading IPA files, running Diag operations and performing Ramdisk-based data recovery. In multi-device workflows, each connected device runs as an independent task, and the task manager shows live status so problems can be spotted quickly.

As general technical context, tools of this type normally communicate with Apple devices over USB and require matching firmware for update or restore operations. This is standard practice for Apple device servicing software and should be treated as general guidance rather than a documented MFC feature.

How to Use MFC macOS V4.5

The supplied release information does not include a step-by-step user guide, so the points below are general preparation guidance only. Always follow the official instructions provided with the software.

Confirm your Mac runs a supported macOS version (Intel: 10.15.7–13.6.3, Apple Silicon: 11–13.6.3).
If you use an M2 Mac, remember that Apple Watch drivers cannot be installed on it. Plan Watch-related work on a supported Mac.
If you need parallel multi-device workflows, ensure the iBUS X hardware is available, as the release notes state it is required for these tasks.
Take a complete backup of any device before running firmware update or restore operations.
Use a good quality USB Lightning cable. For the newly supported Diag models, a DCSD cable is not required.
Follow the on-screen instructions inside the software for the exact procedure, since the detailed operating steps are not specified in the supplied information.

Benefits and Limitations

Benefits

Parallel update and restore across several devices saves considerable time in busy workshops
Standard Lightning cable support for new Diag models removes the need for a special DCSD cable
Multiple backup versions and incremental backups reduce the risk of data loss
Batch IPA installation without an Apple ID simplifies app deployment
Live task monitoring makes it easier to spot failures during long operations

Limitations

M2 Macs cannot install the Apple Watch drivers
The supported macOS range ends at 13.6.3, so newer macOS releases are outside the stated requirements
iBUS X hardware is required for parallel workflows, which is an additional cost
Pricing and licensing details are not specified in the supplied information
No Windows version is mentioned in the release notes
Detailed step-by-step documentation is not included in the supplied changelog

Real-World Use Case

Consider a service desk that receives ten iPhones for the same firmware update before a corporate rollout. Instead of connecting each phone one by one, the technician connects all ten devices, starts the parallel firmware update and watches progress on the task manager screen. If one device stalls, it is visible immediately. The entire batch finishes in one round rather than ten repeated sessions. This scenario is illustrative, based on the documented parallel-update capability, and not a claim of personal testing.

A similar benefit applies to Apple Watch work. With language selection during recovery and post-recovery use without pairing, a workshop handling Watch Series 3 to SE (1st Generation) units can complete recovery and hand the device back with fewer steps.

Safety and Important Notes

Backup first: Firmware restore operations can erase device data. Keep at least one verified backup before starting, and remember that MFC supports multiple backup versions for this reason.
Firmware matching: Always use firmware appropriate for the exact device model. Mismatched firmware can leave a device in a non-working state.
Drivers and hardware: Apple Watch drivers cannot be installed on M2 Macs. iBUS X is required for parallel workflows.
Cable quality: Unstable cables can interrupt long operations. For the newly supported Diag models, a standard USB Lightning cable is sufficient, but it should be in good condition.
Responsible use: Use the tool only on devices you own or are authorised to service. Features such as data recovery and Diag should never be used for unauthorised access to someone else's device.
Source: Download the software only from its official source to avoid modified or unsafe copies.
