Hello, OWC Thunderbolt 4 Dock

Today I installed the used OWC Thunderbolt 4 Dock I purchased for $177 or so on eBay earlier this week.

Ken Rockwell lauds their Thunderbolt 3 dock. Here’s a link to the point on the page where he talks about it. It doesn’t have its own review page on his site.

This is the most recent OWC Thunderbolt dock. It looks like this.

You have to plug your computer into the front USB-C/Thunderbolt_4 slot. You can’t just plug it into the back. If you plug it into the back, nothing works. Okay, that’s fine.

I plugged it into my 48” LG OLED TV with an Amazon USB-C to HDMI cable. It took perhaps 25 seconds, but the image appeared on my TV. I haven’t yet seen how this works on a reboot or power up from a cold Mac. I use my M1 MacBook Pro 16” with a closed list. I hope this works well with reboots and cold power-ups so I don’t have to open the lid to do initial stuff like logging in, or whatever.

1 July 2023 Update: I noticed yesterday that this dock is charging my M1 MacBook Pro 16”. Yay! So plugging my MBP into the front of this dock to connect to its accessories is doing double-duty to charge my Mac. Nice!
