I am considering getting a 14" M1 Pro Macbook and am a bit concerned whether my existing setup will work. That's what I've got:

  • an Early2015 13" MB
  • Apple thunderbolt display via Thunderbolt
  • second monitor via HDMI
  • ethernet via a Thunderbolt-Ethernet dongle
  • USB A keyboard and mouse connected to the Display

Will everything work, especially two external monitors? What dongles/adapters/docks am I going to need?

Thanks.

This should work, but you need some adapters.

  • How many displays can you connect to the MBP with an M1 Pro CPU?

A M1Pro machine can support up to two external screens with each up to a 6K resolution as per Apples spec sheet.

  • What dongles do you need?

The old 2015 MBP has Thunderbolt 2 (TB2) ports, the new MBPs (14" and 16") from 2021 only have TB3/TB4, HDMI, audio and SD-card (also MagSafe 3 but thats just for power). The TB2 connector is different from the TB3/TB4 connector, so you need an adapter for the Apple Thunderbolt Display (ADT), e.g. this one from Apple. The monitor connected via HDMI will work the same, you simply plug it into your new machine and there you go. For the Thunderbolt-Ethernet Adapter you will need a new one as well, you can basically buy any USB-C/TB3/TB4 to Ethernet adapter.
