"Clones pretty much almost killed Apple last time. Why would they go down that same road again?"
At the time Apple was solely dependent on their computer business. Now their main income is from phones and tablets, music sales and App Store transactions.
Licensing OSX could make some money, but at the cost of their own hardware business. Many OSX inclined users would just flock for the cheaper Hackintosh PCs in the end - most people can live very well with a slighly heavier/thicker laptop without Thunderbolt - and with extra USB & A/V ports.
And if the Mac business dried out then Apple would pour even less resources to OSX, and one day they'd just silently end support for it. Like they never announced end of support for Quicktime or Safari on Windows, they just withered away when Apple unplugged them.
