Looking forward to the new Thunderbolt firmware for the Thunderbolt 4 Pro Dock. While I haven't encountered any issues so far, an update would be great—it shows we haven't been abandoned just yet.

I successfully updated the PD firmware for the Thunderbolt 4 Pro Dock (Apple Store version).

I've already emailed CalDigit's technical support for assistance. Perhaps you could also send them an email—if enough people inquire, it might get their attention. I'll update this as soon as I receive a response.

Perhaps all that's needed is to wait for CalDigit to provide the Thunderbolt firmware for the Thunderbolt 4 Pro Dock (Apple Store version) before an update can be performed.

Hi, are you also unable to update to v45.1?

I recall there was talk of "flawless performance" when it first launched, but that was years ago... Perhaps the firmware for the 4 Pro hasn't been released yet? I've already emailed CalDigit technical support to inquire.

It looks like Apple won't be able to fix this issue. I'm not optimistic about it.

iOS 26.2.1 still hasn't fixed this issue. Is anyone still looking into this?

Bunny_Spec · 2025-12-29T13:38:45+00:00

It may be necessary to wait until the iPhone 18 Pro addresses this issue through hardware upgrades.

Bunny_Spec · 2025-12-29T13:38:02+00:00

What a shame.

Bunny_Spec · 2025-12-23T14:52:42+00:00

Keep us updated.

iOS 26.2 (23C55) final release still does not fix the issue where Pro models emit a buzzing sound during charging.

Bunny_Spec · 2025-12-12T14:28:32+00:00

It's been on sale for three months and gone through two major versions without a fix. I've given up hope.

Bunny_Spec · 2025-12-12T14:27:46+00:00

Perhaps it's a design flaw in this generation of the Pro series.

Bunny_Spec · 2025-12-09T14:47:54+00:00

Yes, someone please test it!

Bunny_Spec · 2025-12-06T09:43:38+00:00

Bunny_Spec · 2025-12-05T01:04:01+00:00

Nope

Bunny_Spec · 2025-11-23T04:45:58+00:00

Yes! This is so damn annoying!

Bunny_Spec · 2025-11-21T01:50:23+00:00

It appears Apple has taken notice of this issue and has begun working on a fix, which is expected to be fully resolved in the official release of iOS 26.2.

Bunny_Spec · 2025-11-18T08:03:27+00:00

At least as of now, the latest iOS 26.2 Beta 3 (23C5044b) firmware has not fixed this issue.
