My MacBook Pro that has just been upgraded to OS X El Capitan won't run my DVDs.

What happens when you try?

Can you access the DVD via Finder?

Can you play/read CD's?

You have asked this question 3 times in 3 different threads. Stop, it's enough.

Where was the other one? I reported/fopund only one other.

Apologies, entirely misread this (and then came the editing disaster 🙂 the answer is I don't know now

But here they are:

Wouldn't a real apology consist of helping the OP with his problem? 😉

I am waiting for the answers to my questions. The OP did not provide sufficient information

My comment was addressed to the "apologizer" and not you. It is clear you are attempting a positive approach to the OP's problem! 🙂

Anything you want Mike, ask and you shall have it.
