I have searched, but can't find a general guide for how long Apple will continue to support an OS with updates when the new OS comes out. This issue is now relevant since I have a mid 2009 iMac which will no longer be supported for the new OS: High Sierra.

Thanks in advance,

Usually it's three years. By the way, High Sierra has got the same requirements as Sierra.

The mid 2009 iMac isn't supported in Sierra either.

I must have a compatible (late 2009) model then since I'm running Sierra.

In any case, it's good to know that once I can no longer upgrade the Mac OS, Apple will still have updates for it for three years.

Thanks to all for the helpful replies!!!

My bet is 'three years' is not always the norm....... Just because its always been like that doesn't mean Apple can't change it. And i guess if they wanted to get people using a new OS, it wound make sense to shorter support for older OS's, to get more users to upgrade if they wanna be supported still

For the past couple of years, Apple have issued security and software (Safari) updates for two older versions only. So, right now, updates are issued for 10.10.x, 10.11.x, and 10.12.x. When High Sierra is released, I fully expect 10.10.x to drop off the update schedule. Hardware support for OS versions is another issue. Security updates are what drive my needs. When my hardware no longer supports a supported OS version, then it is time to upgrade the hardware, IMO.

So, to answer your question, I would expect Sierra (10.12.x) to be supported with security and software updates until 10.15.x (or whatever they call it then) is released, two years from now.
