The hall of shame award goes to Apple's Terminal.app. Horrible handling of the bash key shortcuts.
the bash key shortcuts work just fine in OS X's Terminal.app. Can you give specifics, because I'm a hardcore shortcut user and I've never run into problems compared to X11 term apps regarding shortcuts in bash or any other shells for that matter.
Here's the list of supported Macs for the latest El Capitan Beta which goes back to some 2007 models: https://developer.apple.com/library/prerelease/mac/releasenotes/General/rn-osx-10.11/index.html#//apple_ref/doc/uid/TP40016209
As for osx86, I'm running the latest El Capitan Beta just fine on my Main PC (2013ish hardware) and my old Dell Latitude E6420 (2011) without issues - the selected hardware is fully supported. If you want to have OS X run fine on your PC then pay attention to using hardware within the range of what has support, either from Apple or third parties, and you'd be able to run the OS without difficulties.
