Time Machine will no longer support Time Capsule formatted with AFP Apple Filing Protocol

AirPort Extreme Base Station or Time Capsule

These solutions are no longer recommended, because they use Apple Filing Protocol (AFP), which won't be supported in a future version of macOS.

Will macOS future versions allow me to format my Time Capsule disk on my WiFi network using one of the new file formats or protocols the new versions will support? If not, why not? Isn't a disk just a disk and can Apple simply not tell me my old disk format is no longer supported and then display the new formatting options and allow me to select one so my old disk device will be formatted with the new protocol? And then Apple could simply allow me to backup my MacBook just like I have always backed it up, using Time Machine, which I love and my Time Capsule WiFi router and backup system that are all rolled into one, simple and elegant and easy for customers like me to use like Apple is supposed to be. Am I missing something here?

No


If not, why not?


Apple decision to no longer support Time Machine backups over a "network" with future Mac operating systems.


Isn't a disk just a disk and can Apple simply not tell me my old disk format is no longer supported and then display the new formatting options and allow me to select one so my old disk device will be formatted with the new protocol?


No. The Time Capsule disk and any disks attached to an AirPort Extreme can only be formatted in Mac OS Extended (Journaled).....aka HFS+ for Time Machine backups. The same would be true if you were backing up to a Network Attached Storage device (NAS).


And then Apple could simply allow me to backup my MacBook just like I have always backed it up, using Time Machine, which I love and my Time Capsule WiFi router and backup system that are all rolled into one, simple and elegant and easy for customers like me to use like Apple is supposed to be.

We just explained why backups to a Time Capsule using future operating systems will not be supported.


When Apple makes things "official", the only way that you will be able to back up your Mac(s) using Time Machine will require that the backup disk be attached directly to your Mac. When you back up this way, the disk will be formatted in APFS, which is the same format that your Mac's internal drive is using.


The Time Capsule disk cannot be formatted in APFS. Even it could.....(it can't).....backups would not be supported over a network.

Before investing in a NAS, would a LAN-to-USB device exist for which, if connected to a router/switch, the USB would support SMB v3, so a backup HDD would work with Time Machine?


If yes, this would solve, at least temporarily, my Time Machine wireless backup situation - i.e. Mac -> Wi-Fi AP -> Router/Switch -> LAN-to-USB -> HDD - after I decommission the Time Capsule.

Re no more backup to Time Capsule over network; this is disappointing because it worked well. We move on. I have an ASUS AX6600 XT8 mesh Router system. Can you please tell me how to connect an external hard drive to that and then back up my MBP automatically to that hard Drive. Thanks Bill.


That ASUS ZenWiFi AX (XT8) AX6600 Tri-band Mesh WiFi 6 System does not list Time Machine server capabilities in the tech specs:

Unfortunately for this reply, ASC is eating links again, and has basically clobbered this reply. You will want to do some searches of the Asus website for Time Machine support info, for Wi-Fi and Asustor. I’ve attempted to re-generate the text.



There have been reports of issues, as well:


For alternative Wi-Fi mesh router hardware suggestions, see previous replies.


If you wish to preserve that Wi-Fi mesh router, you’ll likely be installing a NAS box. See previous replies.


You’ll be able to continue to operate with Time Capsule until you upgrade to macOS 26.

Thanks MrHoffman! I stand corrected.

You are too kind. That was not a typo, but a blind spot.


I missed the distinction between SMB 3.0 and Samba, and your additional linked information was very helpful for me (and other Readers) to see the distinction.


Using your example, I pulled up the Wikipedia article on AFP.


WOW, what remarkable word-salad including AppleTalk, Apple File Protocol. Apple File System and acronyms and similar terms. No wonder there is some confusion.

Replacing Time Capsule and Synology backup devices. Your helpful comments solicited.

My 20 + year old Synology DS212 NAS drive died this week and my old AFP Time Capsule is headed to the junkyard soon we learned recently. This thread seems to have conflicting info on whether backup devices can be on a home network or have to be attached to a Mac?

I will soon be replacing my 2019 (Intel) iMac and would like to use its drive for one on site backup source over our Ethernet home network. Any reason why this cannot be accomplished? Or are those older iMac drives formatted in one of the Time Machine forbidden formats like the Time Capsule? I would ideally like to replace the Synology drive with something a little less complicated to manage and have that be my second on site backup device running over the home network or attached directly to the Mac.

Appreciate any input, education and suggestions!

I had personal experience with a Synology NAS and it's not one I intend to repeat. Not going to happen.


As for a Time Capsule replacement, no comparable product exists nor is one likely to be forthcoming. A Raspberry Pi NAS will be the TM solution for me. They're ridiculously cheap. Cheap enough to dedicate a separate one for every Mac — not that it's necessary, but it is simple, and (so far) it has been 100% reliable, as reliable as the TCs have been for nearly two decades now.


As for routers, they will probably be either Ubiquiti or Eero mesh systems unless something better comes along... also not likely to be forthcoming.

Thanks.


Just checked and I have 15-inch, 2018, Mac Book Pro. Pretty sure that there is no upgrade path to Tahoe or Mac OS 26 so hopefully I am immune from this change for now.


Disappointing that Apple have dropped support for:


  1. Airport Extreme and Time Capsule. What Mac user does not need to back up solution?
  2. AFP and SMBv1. No legacy support on newer OS post >15.x.x (Sequoia) <16


Also confusing that Apple have switched to yearly release names.



Dec 31, 2025 3:10 PM in response to MrHoffman

Ransomware has been targeting longstanding vulnerabilities in SMBv1 to encrypt the served storage, and to then ransom the data. Or malware just clobbers the data.


Please can you clarify? Does Time Capsule use AFP, SMBv1 or both?


Personally I do not use any encryption on the backup as this likely slows down the process considerably. If working on a private network, how concerned should I be about this data being compromised?


Additionally, what sensible provisions can be made to protect backed up data from any potential ransonware attack?

Dec 31, 2025 3:34 PM in response to 2dareis2do

This is your data, your equipment, your budget, and your decision.


1: Time Capsule supports both AFP and SMBv1.


2: I’m glad your home network is always secure, and your local apps and your local users and your IoT devices aren’t doing sketchy things .


3: Encryption is not just about securing data from access by the inquisitive and by adversaries, but also about the mundane effort of maintaining data security past equipment failure and past equipment retirement.


AI slop doubles the effort in answering too, as it involves not only answering the question and also reviewing the AI slop. AI is not a reliable reference source, though it is a wonderful source of statistically-generated words that might look good. Actual technical correctness is not a consideration. On the subject of AI slop here, AFPS is not involved here with Time Capsule and with Time Machine server. At all.
