All the older FW 400 & 800 devices, scanners, digital tape, audio interfaces have always been able to connect to the latest Thunderbolt ports via two Apple adapters. Why remove the drivers when the adapters allow connecting to the latest port?
Now I can see why Apple discontinued the Thunderbolt 2 to FireWire 800 Adapter A1463. Prices starting to rise on eBay.
 
The other day I did a Target Disk Mode from a 2009-era Mac mini to a MacBook Pro (M2 Pro), the connection was FireWire 800 to FireWire800 cable, then FireWire800 to Thunderbolt 2 adapter, and then Thunderbolt 2 to Thunderbolt 3 adapter. The MacBook Pro was running macOS Sequoia 15.5. It hard crashes the MacBook Pro as soon as it saw the Mac mini and I could reproduce it.

I love FireWire, but the supporting cycle is really ending.

So now I'm curious, what are ya'll using for a Firewire interface on modern Macs? They don't have PCI slots to put an old Firewire card in. Is there a MacOS compatible USB to Firewire adapter?

Either way if this winds up being true, it's the end of an era. I used to champion Firewire back in the day because it was so much better than USB. Unfortunately companies wanting extra licensing per port meant it had to chance to compete with USB. Thankfully USB pulled ahead and the shortcomings it had over Firewire are long gone.
Uh, Apple up until recently sold a Thunderbolt (2) to FireWire adapter. With a Thunderbolt 3 to Thunderbolt 2 adapter, these have been working great with Apple Sillicon macs.
I use these mainly to rescue data from older stuff like old harddrives and DV cameras.

Removal of FW support will now require yet another computer in my collection to do that data rescue.

Although FW is no longer a daily thing for me, there are really expensive sound and video equipment that use FW and those are not cheap to replace.
 
A lot of older audio gear uses firewire, there’s going be a lot of musicians and studios upset by this if it turns out to be how the final release goes

I do wonder if the settings tab shows up if you plug in a firewire device though, it may just hide it to declutter when there’s nothing detected, anyone running the beta who has a TB to firewire adapter want to test?
FireWire-to-USB cables are available and work well, from own experience with older music equipment.

While I agree with you on principle, it’s also very true that legacy drivers still take up system resources and time.
The “Snow Leopard” update people wax poetic about in every other comment section, the one that was famous for shrinking the storage size of Mac OS X… was pretty much only possible because Apple spent that entire update cycle dumping old legacy drivers and bundles from the power PC and classic Mac OS 9 days.

You can’t really have it both ways.
If you just keep supporting every legacy device, you end up with a mess like Windows, where compatibility is great, but actually using the operating system you’ll quickly run into bits that feel like they’ve barely been touched since Windows 95.
Meanwhile macOS is basically the opposite, and within the next two years, them leaving both Intel and Rosetta in the past is both going to be very sad and annoying for consumers, but also very great for the operating system.

I would posit that emojis take up much more system space currently than the firewire driver
 
I use Firewire for 2 devices. A HDV player and a Nikon Coolscan 35mm Film scanner. I use 3 dongles to get firewire 400 to 800 to thunderbolt 2 to thunderbolt 3. It works for me. I hope firewire will be supported. Or, I will have to set up this on my 2012 MacMini.
How is that Nikon coolscan? I’ve been looking into new solutions for 35mm (my canon scanner is networked and can be accessed over ethernet/wifi, but it’s on its last legs and has gone through multiple repairs in recent history)
I also keep a FireWire card in my pc because I still have a GREAT number of DV and HDV tapes in need of transferring (well over 100 left to go, closer to 200) which itself required expensive repairs to the old failing tape mechs in the cameras… then I put the project down because it was so time consuming. I should really complete all of that before something else happens to the cameras, or Windows goes and deprecates FireWire in some W11 update.

Wasn’t there also a hybrid cable where you can use USB instead?

Waiting for the other shoe to drop and Apple to drop USB A 1&2 and older iOS devices using 30 pin connector or iOS 11 and below. o_O

Earlier iPods did not have any USB support. That hybrid cabled was for charge over USB and Sync over FireWire.

This won't really affect my day to day but I do have some older FireWire drives and it will be very disappointing not to be able to access them on my current machine. I'm hoping they add this back in. No reason to remove it.

Thing is, Apple was never known for having amazing backwards compatibility. That is what Windows was doing and still doing to this day. Instead, Apple drops old stuff all the time.
I would argue their track record leans towards backwards compatibility. You can still mount floppy drives. You can't write HFS+ anymore but you can still read it, I believe.

Heck, the update servers for ancient PowerPC machines are still online. Connect a 10.3 machine to the internet and it will download updates. Same with lots of old software.

Heck, with a Serial to USB adapter I can write programs to my Apple //c.
 
I wonder how many people this will really affect as anyone who's been around Macs long enough and still regularly uses Firewire devices likely has an old Mac more than capable of doing what they need with that device (or is using odd workarounds with the Firewire device more as a satisfying challenge than out of necessity).
It’s on a lot of older but high quality sound gear in studios that are still in use, those are going to be the folks hardest hit

I have literally never seen an actual functional firewire to usb bridge, just adapters that do pin mapping for the exceedingly few devices that supported both protocols off a single port (and would fry any standard firewire device), would you care to link to one?

For those of us still using an iPod, I went ahead and tested every other generation model. The good news is, most of them will still communicate with Finder and music tracks can be synced through the Music app. The iPod Classic 4th generation (monochrome model) and iPod Mini 1st generation are detected by Finder but won't load correctly and music won't sync (both of these models share the same chipset).

Another bug is that usually when you select a device in the Music app it will show you the tracks stored on it so you can manage and delete tracks, but on iPods it doesn't work so once you sync tracks onto it you won't be able to delete them from macOS Tahoe.

Also I haven't tested erasing and restoring iPods from macOS Tahoe so that's on my to-do list.

As for FireWire support, I really hope it's just a bug but we will see with the oncoming beta releases.

Hey @Nekomichi , thank you so much for your effort and detailed testing—seriously appreciated! 🙏 I actually created this account just to reply to your post and say thanks for putting in the work. I’ve been trying to sync both my iPad 4th gen and iPod mini 1st gen for almost a week now on macOS Tahoe beta 1, but no success so far either. Both appear in Finder, just like you said, but I can’t sync any music or podcasts to the iPod.

I have to admit though—I’m not using an original Apple 30-pin cable, which might be part of the problem… 😅 Still, your post gave me a bit of clarity on what’s going on.

Looking forward to your update on restore testing and fingers crossed FireWire support gets sorted in future betas! Thanks again 🙌
 
Well, that’s bad news for those of us using Thunderbolt to FireWire 800 adapters to transfer HDV tapes into Final Cut Pro. I’m wondering if they’re dropping support for the adapters themselves, or if this change only affects apps like Music and others.
People say it’s missing from the System Information app entirely, so it’s the whole OS. I also checked the Apple online store, and the FireWire to Thunderbolt adapter is nowhere to be found.

Yeah I use this one

Silly timing. If this would coincide with the end of Intel support or the end of Rosetta then it makes more sense. People still relying on FireWire are likely to also be using legacy Intel-based Macs and software.

Doesn't cost much to support it for 1 or 2 more releases. In fact, it may cost less than to end support now due to the lower volume of angry support calls.
