Autocad 2015 For Mac Will Not Open On Yosemite

Posted on by admin

Good question and might be answered depending on whether your 2015 is an early Macbook or later. If it's an early model and BEFORE OS X 10.11 was released, you should be able to install OS X Yosemite. For example, I purchased a refurbished early 2015 Macbook Pro Retina 13' that came with OS X El Capitan pre-installed. I booted it with a USB thumb drive with an OS X Yosemite installer, erased the drive and installed Yosemite.

I'm using MacBook Pro 5,5 (Mid 2009), and I'd like to install the AutoCAD 2012 for Mac but I couldn't do that because of the message that it said. This version of Mac OS X is not supported. AutoCAD 2012 for Mac requires OS X 10.6.4 or Later'.

So, one way to find out is to use a USB thumb drive with the OS X Yosemite installer and see if it will boot to the OS X Utilities menu and allow your to install Yosemite.


The link from D.Cohen specifically states, 'Your Mac is designed to work with compatible versions and builds of OS X. If you try to use a version or build of OS X that's not compatible with your Mac, your computer might behave unexpectedly.'. There is no reason why a user can not install an older version of OS X that is compatible with the Mac.

Check compatibility

You can upgrade to OS Yosemite on any of the following Mac models. Your Mac also needs at least 2GB of memory and 8GB of available storage space.

MacBook introduced in 2009 or later, plus MacBook (13-inch, Aluminum, Late 2008)
MacBook Air introduced in late 2008 or later
MacBook Pro introduced in mid 2007 or later

iMac introduced in mid 2007 or later
Mac Pro introduced in early 2008 or later
