Some users have reported slowdown or even stuck when using Migration Assistant for disk cloning or data transfer. Below is an example of what Mac users have encountered when using Migration Assistant.
There are various reasons for the problem. If you are experiencing something similar, congratulations on finding this page. Here, EaseUS will provide you with some effective solutions to Migration Assistant slow and offer an alternative.
Why Does the Mac Migration Assistant Take so Long
Migration Assistant slow is common on Mac devices, and many factors can contribute to this. Such as:
- Data Volume and File Size: Transferring many small files generally takes longer than moving fewer large files due to the overhead of handling each file individually.
- Network Issues: Cable performance, unstable Wi-Fi connections, the distance between devices, etc., can affect signal strength.
- Software and System Updates: Outdated software can lead to compatibility issues and thus slow down the transfer speed. Both Macs should be running the latest version of macOS.
- Source Mac Performance: Macs with traditional HDDs or Fusion Drives are slower than those with SSDs due to their inherent read/write speeds.
How to Speed up Migration Assistant
Now that you understand why Migration Assistant on your Mac is transferring slowly. Let's find out what we can do to fix the problem below!
Way 1. Ensure A Strong Network Connection
Both Macs should be connected to the same Wi-Fi network, and you can make sure they are positioned close to minimize interference. If possible, run a speed test to confirm your connection's stability.
If the speed is still slow, use an Ethernet cable instead of Wi-Fi for a faster and more reliable transfer. This can significantly reduce transfer time compared to wireless connections.
Way 2. Update Software
If your network is not the problem, then make sure both Macs are running the latest version of macOS. Here's how to perform Mac Software Update:
Step 1. On both Macs, go to Spotlight in the menu bar and search for and open Software Update.
Step 2. Then, Software Update should automatically begin checking for new software. Click "Upgrade Now" if new software is available.
- Notice:
- Software Update might seem different on other versions of macOS.
Step 3. Enter your Mac administrator password if you're prompted.
Step 4. Wait for the update to complete.
