My Mac Book Pro does not recognize the presence of a DVD or CD

Ever since I upgraded my MacBook Pro, it does not recognize a DVD or CD of any type when I put it in. I have a store bought DVD, the Social Network, which worked fine before upgrading to OSX operating system. Music CD's were okay then, too. Now, neither is even recognized by the player. Thought maybe it needed to be reloaded, but na't figure out how to do that. This is very frustrating, and makes me start to second guess my decision to switch to an Apple product. I've only hd this computer about 18 months, did the upgrade last September (?) and have had difficulties ever since. HELP me please!!!

Use Apple Hardware Test
Open the Help Viewer’s Action pop-up menu (looks like a gear) and choose Print to print these instructions.
Disconnect all external devices except the keyboard, mouse, display, and speakers. If you have an Ethernet cable or external DVD drive, disconnect them.
Restart your computer, holding down the D key while the computer restarts.After your computer restarts, you should see the Apple Hardware Test chooser screen. If you don’t, Apple Hardware Test may not be available on your computer. You may be able to start Apple Hardware Test from the Internet. Reconnect your computer to the network, and then restart your computer while holding down both the Option and D keys.

My mac book pro will not recognize

My mac book pro will not recognize my hp printer after years of knowing it's connected. USB port works fine with other connections. I have reinstaled it. What do I do?

Hi ...
Go to the HP site and download the drivers (software) that is specific to your HP printer model > http://www8.hp.com/us/en/support-drivers.html
That way you will have the latest software available for your printer.
Then open System Preferences > Print & Scan - Print.
Select the printer on the left then click - (minus)
Now click + and follow the instructions. You may need to turn the printer off then back on before your Mac recogizes the new drivers.
You may also need to click the lock icon in the Print window in order to make changes. You may be prompted for your admin password.

Why did I get a free numbers app on my mac book air but not on my imac?

I got a free download of numbers on my mac book air but not on my imac. Why is this?

Hi Pamela,
If it was free on your Air it should be free on your iMac too. Perhaps you should doublecheck that:
Your iMac is running Mavericks (the version of Numbers available for download from the App Store requires Mavericks)
Your iMac is signed into the same App Store ID (usually, but not always, the same as the Apple ID you use to connect to iCloud) as your Air.

My mac book pro does not start but has error message with a question mark on screen. took it in and was told probably the hard drive as could not reconize it so bought new one but still not connecting.what do i do

My mac book pro does not connect but shows an error message with a question mark on the screen.I took it to a retailer that said it was not reconizing the hard drive.He said i needed a new hard drive but it may be something else as well but he was sure a new hard drive would fix it.So putting faith in someone who deals with them i purchased a new hard drive to find it was still not working although he said the computer did know reconize the hard drive and i may have to send it away to get it checked .After already paying 120 pounds for a new hard drive and they wanting another 80.00 pounds to diagnose it i am a little sceptical.
That's why i am interested on anyone's help.

Welcome to the Apple Support Communities
I think that your Mac detects your hard disk, but the problem is that your new hard disk doesn't contain any operating system, so your Mac doesn't find any bootable partition and you see a question mark.
If your Mac came with DVDs, insert the Mac OS X Install DVD and hold the C key while your Mac is starting. Then, just install Mac OS X. If the hard disk isn't prepared to install Mac OS X, you will have to erase it using "Mac OS Extended (Journaled)". See > http://pondini.org/OSX/DU1.html

My new mac book air will not show old emails. how can i fix this problem

my new mac book air will not show old emails. how can i fix this problem

The answer depends on a number of factors, such as the following:
If you have more than one email account, does this problem affect one, some, or all of your accounts?
Where did you last see this mail -- in your Inbox(es)? in some other folder(s) outside your Inbox(es)? somewhere else?
How old is the missing email -- yesterday? just before you got the new computer? over a week? over a month? over a year?
How are you reading email -- with the builtin Mail application? with some other mail-reading application? with a web browser?
How do you access your email on the server -- IMAP? POP? Exchange? web browser? other?
What version of OS X is on your new computer -- Mavericks (10.9.x)? Mountain Lion (10.8.x)?
Did you migrate your data and applications from your old computer when you set up your new computer?
For example, if the missing mail is the mail that was in your Inbox before you got the new computer, you are reading it with the builtin Mail via POP, and you failed to migrate data, then the mail was left behind on the old computer. The same would be true if the mail was in "On My Mac" mailboxes and you failed to migrate data.

My Mac Book pro does not recognise the wi-fi net. How to fix it?

My Mac Book Pro does not recognise properly the Wi-Fi net at home. I've tried many ways in "preferences", but it realy does not work. When connected in the Ethernet port, it works perfectly.
Don't have any problems with other computers at home.

I don't know what you mean by "doing new concessions on DHCP"!!??? Have you tried using a static IP address to see if it works that way? Have you restricted the range of DHCP addresses available at your router? If you have maybe the other computers have used up the available range. Suggest you try a static IP address first, then we'll take it from there.
