Mavericks on Retina iMac

I know, it is probably not supported since they only support the most recent OS version upon release.

However, did anyone actually try to install it?

There should be no driver in Mavericks to handle the RiMac's hardware.

It won't work, simply because Mavericks doesn't have the necessary drivers to support the R9 GPUs.

Are we sure of that?

Very. I tried booting off an external Mavericks disk myself on my riMac. It just won't boot.

How do drivers under OSX work? Can you just take the Yosemite drivers for the AMD chips and integrate them into Mavericks?

I'm interested in this too. My institution has told me that they are planning on running Mavericks on my new iMac when it arrives. Hmmm.

If it's stability you're worried about futzing with drivers to get an older OS X working will make it unstable.

I'm interested to see if this is doable as well. Since I never purchased the Yosemite version of OS X Server I may want to run Mavericks from time to time. Luckily I do have a Mac mini running Mavericks, so this hasn't crippled me.

Does it make sense to run Mavericks as a VM on Yosemite with Parallels ?

I run Mavericks in Parallels and it sucks, especially the graphics. It'll show in Retina, but all the animations are full of lag (it even shows 256 MB VRAM though I gave it 1024). Wake from sleep does not work, it will randomly go to the login screen from time to time, the problems go on and on. Checked the VM settings, nothing seems to resolve these problems.

Here's proof that it actually does work in Parallels. Sort of.

Good luck to your institution getting that working. Mavericks won't boot on the retina iMac. They might need to rethink that.

I'll let you know what comes of it.

There is no hardware graphic acceleration in parallel OSX, that's why the graphic sucks. ATM, it's impossible to get that due to the restriction from Apple, not Parallel's fault.

September 7, 2015 Update

Latest build of Mavericks - OS X 10.9.5 (13F1112) seems incompatible with iMac 15,1 (Retina 27-inch Late 2014)

I was unable to boot from an Mavericks Install Drive built using a fresh download from App Store.
