The Dell Thunderbolt Dock WD22TB4 is compatible with MacBook Pro models, including those with Thunderbolt 3 or 4 (USB-C) ports, but there are some limitations and security issues to consider:

- Charging power: The docking station can deliver up to 130 watts of power, but when used with a MacBook Pro, the charging power is limited to a maximum of 90 watts. This is because MacBooks only support USB Power Delivery 2.0 (or higher), which allows for less power than the maximum possible from the dock.

- Safety: There is no indication that the docking station could harm your MacBook Pro due to the charging power as long as the above limitations are observed. The docking station is specifically certified for compatibility with Apple devices and should therefore be safe to use.

- Functional limitations: There are some functional limitations when using the docking station with a MacBook Pro, such as being limited to a maximum of two external 4K monitors or one 5K monitor, and certain functions such as Multi-Stream Transport (MST) or Wake on Dock are not available.

Overall, the Dell Thunderbolt Dock WD22TB4 should be safe to use with your MacBook Pro as long as you follow the specific compatibility requirements and limitations.
