Networking changes coming in macOS 27

https://eclecticlight.co/2026/04/23/networking-changes-coming-in-macos-27/
Time Capsule has been unsupported since 2018 (last shipped 2013):

I think there's some population of folks that have been doing NAS TM backups over AFP, and they'll now have to switch to SMB.

For those that are interested: I've managed to build Samba 4 and get it running on a Apple Time Capsule https://github.com/jamesyc/TimeCapsuleSMB
In comparison to other 'changes' Apple usually do those one are realistic. Dropping deprecated networking practices that worth upgrading (meaning, if you already have newer macOS clients mostly with apple stack, update your servers)

I just hope they won't break anything they don't need to break (which is more concerning usually) and that they won't drop other things that do make sense to keep until transitioned properly (eg. OpenGL as one example)

Although TimeCapsule is more than decade old, it serves nicely with TimeMachine (automatic backups). Sad to see that going away permanently for Apple Silicon.

"...if you have an Apple silicon Mac and AFP support is dropped from macOS 27, that would leave you unable to upgrade without replacing your network storage."

How big is this market? I'm not saying vibe code a product, but...

> will require connections to certain servers to be made using at least TLS 1.2

Seriously, no-one should still be using 1.1 since ... 5 years ago? It's not even the 1.2 -> 1.3 previous upgrade problems we're talking about.

On an unrelated note, I use Time Machine and I’m surprised at how unpolished, not to say downright buggy, all the animations are. They used to look magical, but now they are a mess of elements popping on and off and things moving and then vanishing the next frame and so on. It looks like they kept changing Finder and Time Machine didn’t keep up; they kept fixing the bare minimum to have it compile and nothing more.

I’m reminded of that time 10-years ago when Apple rewrote parts of its networking code (discovery/mDNSResponder), and it caused so many issues they had to revert the code.

Finally, TLS 1.2 is baseline, after having been released 18 years ago.
Why is it that Apple products attract blogspam titles?

> Networking changes coming in macOS 27

And yet:

> This year, with just over six weeks to go before that first beta of macOS 27, we already have two warnings of what might be coming.

> It repeated those warnings with macOS Sequoia 15.5, but still hasn’t confirmed when AFP will be lost.

> Although Apple carefully avoids being too specific, it warns that this change could come “as early as the next major software release”,

When i saw the headline I briefly allowed myself to hope that DNS settings would no longer be set universally (requiring manual intervention when switching networks if not using DHCP) but of course it's nothing useful and only "Apple is breaking stuff because they can"
>Apple made SMB its primary file-sharing protocol in OS X 10.9 Mavericks, over 12 years ago…

…and yet SMB support in macOS remains slow and buggy to this day. I tried all combinations of server-side settings and obscure plist tweaks to make SMB navigation and search work as fast as they do on my Linux machine out of box before giving up. It is very obviously not a priority for their services revenue, so there’s no incentive for fixing any of the long standing problems.

Completely unrelated but I love the layout / blog format of eclecticlight.co
Can't they hire an extra dev per abandoned project to not abandon it?

I'm still using my time capsule. I don't really trust the hard drive inside of it, but I basically use it to connect to an SSD that I attached to it. Unfortunately, Nest Wi-Fi, that I use as a router doesn't have any USBs, unlike some cheaper routers. I know that it's, I know that it will be gone after Tahoe. I'm still not sure what I'm going to do about this. I mean, I don't really want to fool on us

I mean, it's basically just like a time machine backup plus, uh, a little bit of some older files that I don't want to keep on my main Mac.

seems like any NAS would take way more space than I would love to. I suppose one alternative would be actually getting some kind of like Beelink PC and then maybe setting up a proper home server, moving some of my side projects in there, running plex from it. The problem is that the current ram prices, it's a surprisingly expensive solution.

This update broke my workflow! I use Netatalk [1] with AFP to share files between my Macintosh 512ke and MacBook via AppleTalk.

Look, my setup works for me. Just add an option to re-enable AFP [2].

Wouldn't the TimeCapsules still work over wired connections, just like any other hard drive, even if the networking AFP protocol support is dropped?

Next: macOS iCloud backups and the eventual deprecation of local Time Machine backups altogether. More services revenue!

Ubiquiti is really taking up the slack in some areas Apple has abandoned.

I bought a UNAS-2 (and a couple of 12 TB IronWolf Pro drives) a few months ago when the "time capsule will not be supported in a future version of macOS" warning first appeared. It has been outstanding alongside the rest of my UniFi setup, and perfectly supports Time Machine backups. The UniFi Identity macOS app means my family's computers always stay authenticated/connected and my wife & kids don't have to do anything to make Time Machine just work.

If you're a power user who loves the Apple aesthetic and you already have a UniFi setup at home, you'll feel right at home switching from Time Capsule to a UNAS.

Does the mac still lack a SMB/CIFS browser?

I was shocked years ago that the mac, famous for its early network peer discovery and zeroconf and all, couldn't present a list of SMB servers and shares despite that kind of function being around forever on every other platform in existence.
