Is there a date or timeframe regarding the end of life support for El Capitan?
We are trying to develop strategic plans for MacOS upgrades and purchases, but desperately need some insight on new MacOS release and current MacOS lifecycle support roadmap or future plans.
As we are not Apple, we cannot give you any definitive date for when El Capitan will no longer receive security updates. We cannot even tell you for sure that the release of macOS Mojave will be when El Capitan is no longer supported. Only Apple knows.
What Eric has related was how Apple has behaved in the past.
Public Mojave knowledge is what was announced at the World Wide Developers Conference in June
<macOS - Mojave Preview - Apple>
All Apple has said about the Mojave release data is "Fall 2018". Fall officially ends 21-Dec-2018, and if Mojave is not ready for release by then, Apple will delay its release until they are happy with the software. There are most likely lots of behind the scenes reason Mojave will be released before that date, but the reality is that "Crystal Balls" are not what they used to be.
If you really need something definitive, you will need to contact Apple.
If Apple continues what it has done in the past, support for El Capitan will end with the next macOS release. There may be some security updates.
I am really searching for a date or time-frame for the next macOS release and subsequent eol for El Capitan.
Normally, it is in the end of September or October. This fall.
MacOS end of life
