upgrade from osx 10.9.5 to 10.11.4

Attempting to upgrade from 10.9.5 to El Capitan 10.11.4 the system tells me it needs 10.11 - not mentioning which release, and in addition I am not able to find any location that allows uploading an interim version.

Copyinfg the installation app from my MBook, whihc I upgrades months ago, results in an error message (probaby defective or altered copy of this app....)


What can I do?

iMac, OS X Mavericks (10.9.5)

You need to download the full installer from the App Store. this will download the latest version which is 10.11.4.

Once it is downloaded and before you install it make a copy of Install Mac OS X El Capitan.app which you can find

in your Applications folder, drag and drop this app to another part of the mac or onto a usb stick or similar. This comes in handy in the future

in case you need to reinstall the OS, saves having to do it over the net.


Click the download button when you get to this screen on the App Store.

I wonder when it happens the first time that the answer to a question arrives before I have sent the question!

You guys are supersonic, thanks!

So,

Eau Rouge is right, I downloaded the full 10.11.4 dmg and after unpacking etc. I got this message that 10.11 is needed to update to 10.11.4 - which I thought means some previous releases like 10.11.1, .2 or .3 ... So I stopped it. This cannot be just a warning message telling me what I am about to do anyway, I mean we don't talk about Windows...

Well then: Should I ignore the hint (I'm not sure whether the system would continue the install anyway, but I can try)


@Grant: I know about the limitations with other programs, I had this on my MacBook, too, and there were workarounds using old flash plugins that did the job for Adobe apps. And all the rest works smoothly. (Except mail which takes forever to load my mails - but this can be due to the amount of emails or the slow data rate.) The reason why I want to update the iMac is that the calendar agent app crashes every couple of secs, and this drives me nuts. Switching it off is no solution if you use external cals, so I thought to solve the problem with a full new installation.


Waiting for your reply - many thanks in advance from Germany

the delta update; updates 10.11.3 to 10.11.4

the combo update updates any version 10.11.(version.1.2.or .3) to 10.11.4

when a new update is released many people are will advise using the combo

as it resets some system files for the OS.

whenever the App Store update section recommends an OS update

it is sometimes best to go to the Apple Support Downloads pages

and download the Combo update. It normally downloads quicker.

This seems to be the point: My current version is 10.9.5, so I assume that I need to update first to a 10.10.x and then to an early 10.11.version.1.2.or .3. But I don't find any download source for these.

No, you need to download 10.11 from the App Store, just as Eau Rouge has explained. This will give you 10.11.4 directly – no further updates needed after that. (You don't need, and can't even download 10.10!)

upgrade from osx 10.9.5 to 10.11.4
