I just got my new Macbook Pro recently and need some Blu-Ray software and optical drive recommendations from experienced users.
You have many choices just as Hovsep A said but in my opinion, I prefer iReal mac blu-ray player and I have been using it for a long time. You will enjoy your movies here.
In fact, I don't think any one of Mac Blu-ray Player software is mature.
You're not going to see an image quality difference between various software / hardware configurations. Just purchase the hardware with the best price and the software with the interface you enjoy.
Perhaps Having LED or LCD TV can do some difference regarding the quality of played Bluray video.
perhaps you need internet connection to grab the decryption keys
