1.Check Power Delivery:
Use the included 180W power adapter for the dock (verify it’s plugged directly into a wall outlet, not a power strip).
Disconnect non-essential peripherals (e.g., USB accessories, card readers) to reduce power load.
2.Test SSDs individually: Connect one SSD at a time to isolate if a specific drive/draw causes disconnects.
Thunderbolt Cable & Port:
Swap the Thunderbolt 5 cable with a certified 80Gbps cable (some cables ship with defects).
Connect to a different Thunderbolt port on your Mac mini M4 to rule out port-specific issues.
3.Monitor Bandwidth Allocation:
Lower monitor resolution/refresh rates: High-res monitors (4K/6K) consume significant bandwidth. Temporarily reduce to 1080p/60Hz to test.
Avoid daisy-chaining monitors: Connect each display directly to the dock’s dedicated video ports (HDMI/DP).
4.SSD Optimization:
Use Thunderbolt or USB4 SSDs (not USB 3.x): Older SATA-based SSDs can bottleneck bandwidth.
Format SSDs as APFS (macOS-native) for stability with large files.
Test file transfers via direct connection (SSD → Mac) to confirm the dock is the culprit.
5.Thermal Management:
Place the dock in a ventilated area (overheating can cause resets). Use a small fan to test cooling.
Check for firmware updates again: Visit Beelink’s support page for dock-specific updates (not just macOS).
6.Thunderbolt Bus Prioritization (macOS Settings):
Go to Apple Menu → System Settings → Network → Thunderbolt.
Set “Priority” to High for the dock connection.
7.Reset Mac’s Thunderbolt Controller:
Shut down the Mac.
Unplug all peripherals + power cable for 60 seconds.
Reconnect only essentials and power on.
8.Create a Dedicated Diagnostic User Account:
Test transfers in a new macOS user profile to rule out software conflicts.
