Apple continues to put out new macOS releases. We can't run builders for all of them forever.

I propose we announce in the Go 1.10 release notes that Go 1.10 will be the last release to officially support macOS 10.8 (Mountain Lion).

macOS 10.8 was last updated Oct 3, 2013, over 4 years ago.

(macOS 10.9 was last updated Mar 21, 2016, 19 months ago, which is somewhat more recent)

Apple doesn't publish official End-of-Life dates for macOS versions, but I read that their security policy is that they issue security updates for the past 3 releases.

Given that they're on 10.13 now, that means 10.13, 10.12, and 10.11 are supported by them.

Our policy of additionally supporting 10.10 and 10.9 in Go 1.11 would be even more.

Looks like we could plausibly drop support in Go 1.11 for both Mountain Lion (as previously agreed) and also Mavericks. By the time Go 1.11 comes out in August 2018, Mavericks will have gone two years since its last security update.

version released updated security update
OS X 10.8 Mountain Lion Jul 2012 Oct 2013 (10.8.5) Aug 2015 (2015-006)
OS X 10.9 Mavericks Oct 2013 Sep 2014 (10.9.5) Jul 2016 (2016-004)
OS X 10.10 Yosemite Oct 2014 Aug 2015 (10.10.5) Jul 2017 (2017-003)
OS X 10.11 El Capitan Sep 2015 Jul 2016 (10.11.6) Dec 2017 (2017-005)
macOS 10.12 Sierra Sep 2016 Jul 2017 (10.12.6) Dec 2017 (2017-002)
macOS 10.13 High Sierra Sep 2017 Dec 2017 (10.13.2)

Filed #23122 for the actual removal work (whatever that is). Looks like we'll be caught up once Go 1.11 is out and then once caught up we should probably plan to deprecate one Mac OS version each year, alternating between preannounce and remove.

Go 1.12 preannounces dropping Yosemite
Go 1.13 drops Yosemite
Go 1.14 preannounces dropping El Capitan
Go 1.15 drops El Capitan
Go 1.16 preannounces dropping High Sierra
etc.

Let's make this issue the open-forever tracking bug for this sequence. Moving to Go 1.11; once Go 1.12 milestone is created, can move to Go 1.12.

@rsc rsc modified the milestones: Go1.10, Go1.11 Dec 13, 2017

One bit of information ignored by the above table is which Mac hardware is dropped by each OS versions. Some macOS versions are "tocks" that drop hardware support, others are "ticks" that don't drop hardware support. I think this should be analyzed when taking decisions.

Also this page reports the usage share between different macOS versions:
http://gs.statcounter.com/macos-version-market-share/desktop/worldwide

Mavericks is about 5% of all Macs, while Mountain Lion is non existing.

The statcounter.com page makes no sense to me. I don't believe their numbers at all.
