Oct 09, 2015 I can’t access the free update for the El Capitan OS X on my iMac. This one has Mavericks 10.9.5 pre-installed. Every time I try to update it from the app store, I get this message: “This version of OS X 10.11 cannot be installed on this computer” I googled around for a while, but I got a few suggestions that I wasn’t too sure of. Oct 01, 2015 How to overcome OS X 10.11 El Capitan not installing. As with prior versions of OS X, the new version 10.11 “El Capitan” is available as a free purchase from the App Store, and should then download and run to allow you to upgrade your system. If all goes well, you should see the OS X installation window that instructs you to begin the upgrade process, but there may be instances where this does not appear, or does not work when you attempt the install. I'm trying to upgrade to OS X El Capitan from OS X Snow Leopard 10.6.8 but every time I try to download it from the Mac App Store it gives a message saying that 'this version of OS X 10.11 cannot be installed on this computer'. I have a MacBook Pro running OS X 10.6.8, 3 GB of RAM and around 400 GB in the HD.

Firefox version 78 is the last supported Firefox version for Mac users of OS X 10.9 Mavericks, OS X 10.10 Yosemite and OS X 10.11 El Capitan. These users will be moved to the Firefox Extended Support Release (ESR) channel by an application update. This will provide security updates until the next ESR update in July 2021, after which the affected users will no longer receive security updates.

While Apple does not have a public policy governing security updates for older OS X releases, their ongoing practice has been to support the most recent three releases. The last security update applicable to OS X 10.11 was made available in July 2018. Unsupported operating systems do not receive security updates, have known exploits and can be dangerous to use, which makes it difficult to maintain Firefox on those versions.

Up until July 2021, we will be updating affected users with critical security updates through the Firefox ESR channel to help retain the best possible security. After this, no security updates will be provided.

If you want to keep your Firefox version up to date, you will need to upgrade your operating system to macOS 10.12 or higher. Older versions that are not supported by Apple are unreliable and unsafe to use, which also makes it difficult to maintain Firefox on those versions.
