I have a Macbook Pro (13-inch, M1, 2020 running Ventura OS) that seems to work with the old Thunderbolt display, but not the OLDER Thunderbolt display that only has the 3 USB ports in the back. Any suggestions on how to make this work?
Hello Gone2thebeach,
Thank you for using Apple Support Communities.
If you are having issues with setting up an external display with your Mac, we would suggest reviewing the steps for setting up an external display: Connect a display to your Mac - Apple Support
If you run into issues with the external display on your MacBook Pro, the steps here could help: If you can’t see your Mac desktop on an external display - Apple Support
Best regards.
WHICH Thunderbolt Display? and are you certain it's not the Apple Cinema Display?
The Apple Thunderbolt Display lead-in cable has two connectors: Thunderbolt-2 and MagSafe
The Apple Cinema Display lead-in cable has three connectors: Mini DisplayPort , MagSafe, and USB-A
Apple Thunderbolt-3 <-> ThunderBolt-2 adapter is the only way to run a genuine Apple thunderbolt[-2] display from a Thunderbolt-3 or -4 Mac.
This US$50 adapter supports ONLY ThunderBolt displays, no other types of displays, even with additional adapters.
