Downgrade to Mavericks

Yes.

Install OSX Restrictions

You cannot get Mavericks or Yosemite from the App Store now. You cannot install an older version of OS X on a machine that shipped with a newer release of OS X. The hardware device support for the new machine is not in the older release of OS X.

El Capitan is a substantial improvement over Maverick in every regard. Apple is about change, not dormancy.

I dont care about the looks but functionality. The worst part is new OS X El Cap or Yos has worse font rendering, small and thin fonts and harder to read on even macbook pro retina and imac Retina. I ended up buying macbook pro retina 2014 and installed Mavericks on it. I am also selling my iMac retina. Stg is really wrong, gave many feedbacks to Apple, some adjustment I see from Apple but still not like Mavericks or previous font rendering. Color scheme and font rendering is real issue for the productivity and eyesight.

Apple has never allowed installing an older OS version than what the machine came with.

And, Yosemite was introduced last year (one year old), so Mavericks was introduced in 2013 which makes it 2 years ago.

Earlier this year I purchased a late 2012 iMac from the Apple refurb store purposely - it came with Mountain Lion and I've been running Mavericks on it because that it the last OS version that allows me to run my movie apps. I am running the latest (El Capitan) on my MBP (which also came with ML); I have bootable clones made before upgrading, so I could easily revert if I wanted to. So, if you want to run an older OS, consider checking the refurb section at the Apple store - the inventory changes rapidly; a 2013 machine might come with Mavericks. I managed mine by starting a store chat and telling them I only want it if it has ML or Mavericks installed. That worked!

If you would like to run mavericks on an internal drive on a mac book pro please make sure you buy one from late 2013 at the latest. Used is your best option ebay apple refurb craigslist :/ Search for creating bootable mavericks installers... I know mac world has a few articles on how to's. Go with the usb option, and then create one for every os x apple comes out with if your ecosystem is mac-centric. That way your always good. Very few people know that with a few tricks you can creat a bootable external drive... Meaning buy a high quality external hard drive install mavericks os x on it plug it in to a usb thunderbolt port on your 2014-15 MBP and then via the (startup drive) in (preferences) you can actually boot and run Mavericks on a new macbook pro.... There are internet intructables on youtube and reputable websites... Many people need new computers for peripheral connectivity for their jobs and still need to run software that is only operational on mavericks. Make sure your hard drive is quality if you plan on going this route. In the solid state categories the samsung evo 850 or the owc ssd's will work great!

Im all for progress, but more and more the smart creative company and its users / employees seem to be turning in to cultists following the dogma passed down from above. That being said its the shareholders fault they have to move so rapidly to turn a quartly profit. They still make great products that last a long time taken care of the right way... but their developers need to slow down and not get rid of great features that help power users and home computer users alike for the sake of simplicity, empower us, don't dumb us down, we get enough of that from everywhere else... Shouldnt come from apple as well! 😉

hope the info helps!
