all: end support for macOS 10.15 in Go 1.23 #64207

dmitshur · 2023-11-16T16:02:21Z

Go added support for macOS 14 that was publicly released this September. After internal discussion, we believe the summer of 2024 will be a good time to drop support for macOS 10.15. The last security update it received was in July 2022.

On behalf of @golang/release, I propose we announce the end of support in the Go 1.22 release notes, and disable the builder for Go 1.23.

CC @golang/darwin.

rsc · 2023-12-06T18:41:17Z

Usually we link to our macOS history in these issues. Is #23011 (comment) the most recent statement of our history? Is there a better policy link?

Regardless, since Apple stopped issuing updates in July 2022, and dropping in Go 1.23 would mean we stop issuing security patches (for Go 1.22) at the release of Go 1.24 in Feb 2025, that seems entirely reasonable. If anything we seem late.

dmitshur · 2023-12-06T19:52:15Z

We had been following that pattern of adding a new macOS version and dropping the oldest one every 2 Go major releases (i.e., once a year) for a long while. After Go 1.17, there was a longer period where we supported older macOS versions, but Go 1.21 caught up by dropping two at once (proposal #57125).

If this proposal is accepted, then:

Go 1.22 (security patches until Feb 2025) is the last release with macOS 10.15 support
Go 1.23 (scheduled for Aug 2024 release) drops macOS 10.15, requires macOS 11

And if we continue dropping oldest macOS once-every-two-major-Go-releases after that, the pattern would be:

Go 1.24 (security patches until Feb 2026) last to support macOS 11
Go 1.25 requires macOS 12
Go 1.26 (security patches until Feb 2027) last to support macOS 12
Go 1.27 requires macOS 13
Go 1.28 (security patches until Feb 2028) last to support macOS 13
Go 1.29 requires macOS 14
...

lpar · 2023-12-08T15:00:34Z

It would be good to have a page somewhere indicating minimum OS versions currently required for the Go toolchain, and minimum OS versions supported by the Go runtime. (Apologies if there is one, but I haven't been able to find it.)

dmitshur · 2023-12-08T15:21:30Z

@lpar Minimum OS version information is there but can be made easier to find—see #41212 for that.

randall77 · 2023-12-08T15:34:20Z

https://github.com/golang/go/wiki/MinimumRequirements lists the minimum OS versions we require.

lpar · 2023-12-08T16:29:30Z

Thanks. Do the minimum version requirements apply to the runtime for built binaries?

randall77 · 2023-12-08T16:33:43Z

@lpar I'm not sure what you are asking. They apply to everything in the built binary, runtime included.

lpar · 2023-12-08T19:35:07Z

Thanks, that was what I was asking, whether ending support for macOS 10.15 meant that binaries compiled by the Go toolchain would no longer be supported on 10.15.

(Binaries built with Go 1.21.x still seem to work on some unsupported macOS versions, but of course that doesn't mean it's supported that they do.)

rsc · 2023-12-09T18:15:24Z

Based on the discussion above, this proposal seems like a likely accept.

Following our usual pattern, more or less:

Apple stopped issuing security updates for macOS 10.15 in July 2022.
Go 1.22 (security patches until Feb 2025) is the last release with macOS 10.15 support
Go 1.23 (scheduled for Aug 2024 release) drops macOS 10.15, requires macOS 11

richardwilkes · 2023-12-09T18:50:48Z

Shouldn't Go only drop support for older OS's if both:

they aren't supported by the vendor any longer (which seems to be the current stance)
changes in the Go toolchain are actually required to continue supporting them

Naively, it appears that the second case isn't true for this (or many of the previous drops). Other than keeping some builders alive, is there any real downside to allowing the latest Go toolchain to continue working on these older OS releases that we already have working?

I'm asking because I like to stay with the current Go releases when developing, but this policy is going to force me to stop doing that, since a subset of my clients use OSs that are older than the officially supported versions out there.

randall77 · 2023-12-09T19:01:55Z

The problem is builders. If we support something, we need a builder for it. Running builders that aren't supported by the vendor is bad, because they are 1) connected to the internet, and 2) not receiving security patches.

richardwilkes · 2023-12-09T20:05:08Z

@randall77 it seems that security patches aren't the determining factor, as current versions of Go claim support for Linux kernels going all the way back to 2.6.32, which was EOL'd in March of 2016 (and versions of the 2.6.x line newer than that were EOL'd much earlier than that).

randall77 · 2023-12-09T20:27:04Z

See #60792 , there are ongoing discussions there about bumping the linux min version.

RHEL 6 is still supported and runs a 2.6.32 kernel. https://en.wikipedia.org/wiki/Red_Hat_Enterprise_Linux

richardwilkes · 2023-12-09T20:32:03Z

OK, fair enough. I didn't realize any Linux distributions were still supporting it (the few I checked were far beyond it).

Anyway, definitely not happy about dropping support, but can understand it.

rsc · 2023-12-13T18:41:10Z

changes in the Go toolchain are actually required to continue supporting them

You'd be surprised how much ongoing work it takes to keep all our builders running. Much of that work isn't visible as changes in the Go toolchain. Not running older, unsupported builders frees up time for higher priority work.

rsc · 2023-12-14T04:44:02Z

No change in consensus, so accepted. 🎉
This issue now tracks the work of implementing the proposal.

What's left to do for this issue (wearing my release interrupts hat) -- just something in the 1.23 release notes? Or do we need a change to the old (pre-LUCI) coordinator as well?

dmitshur · 2024-02-14T16:34:19Z

Thanks for checking in. Here's a list showing the status of the remaining work here:

disable macOS 10.15 builders on the main branch (keep it for release-branch.go1.22 and older) (CL 558197)
- Maybe it's worth doing for coordinator too, even though it's going away. (CL 564215)
add a note to Go 1.23 release notes (CL 563856)
update the minimum macOS version in the x/build/internal/releasetargets package so that the macOS installer is updated to check for Big Sur as the new minimum (CL 564217)

I've sent a release note CL just now, but the releasetargets package will be undergoing some bigger changes soon enough. I'll take care of it later on.

All this needs to be done before Go 1.23 RC 1, but fine to ping if not finished by the release freeze.

Is there a need to update this line in the linker https://cs.opensource.google/go/go/+/master:src/cmd/link/internal/ld/macho.go;l=486 ? Perhaps it is fine either way... Or we can wait until the old version causes some trouble.

dmitshur · 2024-02-14T18:14:26Z

Thanks for pointing that out. The comment there says "This must be fairly recent" and "In general this can be the most recent supported macOS version." If I understand correctly, that means it shouldn't cause problems to set that version to macOS 14, the most recent macOS version now, and that there's no hard requirement for it to not fall below the minimum macOS version that Go supports. We didn't update it for when macOS 10.13 became unsupported.

For now, I sent CL 563857 which seems like a small and safe step forward today. We can see if there's something more principled we should do for maintaining the version there later on.

Go 1.23 will require macOS 11 Big Sur or later, even on AMD64. The comment here suggests the main requirement for the OS and SDK version is to be recent enough not to break Apple signing, and recent enough not to cause other problems. For now, this CL simplifies the code by merging the ARM64 and AMD64 cases into one, given 1.23 will be the first Go release with a common minimum macOS version for both architectures so there's no need to treat them separately here.

Hmm ... it is a shame though. I'm currently forced to use my old MacBook Pro from early 2013 which does not support macOS 11, which means that I need to stay on macOS 10.15 (unless I use something like https://dortania.github.io/OpenCore-Legacy-Patcher/).

With this decision, it also means I can no longer use the latest Go if I understand this correctly (unless I can build from source?).
