The bootable Mac OS X Snow Leopard Install DVD-ROM is important if your Mac ever refuses to boot like normal. If you don’t have a bootable DVD-ROM — preferably a Mac OS X Snow Leopard Install DVD-ROM — call Apple or your Apple dealer to arrange for a replacement.
What is the best mac cleaner free. To boot your Mac from a DVD-ROM installation disc, follow these steps:
- Insert the Mac OS X Install DVD into the DVD drive.If your Mac uses a tray to hold the DVD, make sure that it retracts and that the disc is in.If you have a tray-loading DVD-ROM drive and it’s closed, you can get it to open by restarting (or starting up) your Mac while pressing the mouse button. Continue pressing until the drive tray pops out; then release.
- Shut down or restart your Mac.If you shut it down, wait a few seconds and then start it up the usual way.
- Press and hold down the C key immediately, and keep it pressed until your Mac either boots from the DVD or doesn’t.If it does boot from the DVD-ROM, you see a Welcome screen.If it doesn’t boot, you see a prohibitory sign, spinning-wheel-of-death, or kernel panic alert. . . anything but the first screen of the Mac OS X Installer, the login window, or the Finder. Any of those is your cue to try Step 4.
- If your Mac doesn’t boot after Step 3, hold down the Option key while booting to display the built-in Startup Manager.Use the built-in Startup Manager when you boot from a DVD.It displays icons for any bootable discs that it sees and allows you to select one (including the installation DVD).
- Yosemite 10.10.2 dmg. Click the DVD-ROM icon to select it, and then press Return or Enter to boot from it.This technique is quite useful if your usual boot disk is damaged or having an identity crisis during startup.
If you can’t boot from DVD then either you just installed something new that’s aggravating your Mac, or your Mac needs to go in for repairs (usually to an Apple dealer).
To get your Mac up and running again, you can try any of the following:
- Call the tech-support hotline: Before you drag it down to the shop, try calling 1-800-SOS-APPL, the Apple Tech Support hotline. The service representatives there may be able to suggest something else that you can try. If your Mac is still under warranty, it’s even free.
- Ask a local user group for help: Another thing you might consider is contacting your local Macintosh user group. You can find a group of Mac users near you by visiting Apple’s User Group Web pages.
- Try Dr. Mac Consulting: You can check out consulting services or call 408-627-7577. A team of expert troubleshooters does nothing but provide technical help and training to Mac users, via telephone, e-mail, and/or Internet-enabled remote-control software.
- Check whether you have RAM issues: If you have problems immediately after installing random-access memory (RAM) — or any new hardware, for that matter — double-check that the RAM chips are properly seated in their sockets. (Warning: Don’t forget to shut down your Mac first.) With the power off and your Mac unplugged, remove and reinsert the RAM chips to make sure they’re seated properly. If you still have problems, remove the RAM chips temporarily and see whether the problem still exists.Follow the installation instructions that came with the RAM chips — or the ones in the booklet that came with your Mac. But even if they don’t say to get rid of the static spark, you should (by using an antistatic strap available from most RAM sellers or by touching an appropriate surface, such as the power-supply case inside your Mac) before you handle RAM chips.

Why be careful? If you are considering trying this, your drive already doesn't work. What could you possibly do - make it blow up? Sure, maybe you could break it worse, but non-functional is non-functional, so what difference does it make if you do? :-)
You answer your own question: if someone isn't careful while using this cleaning method, they could break something in the optical drive and REALLY make the drive useless. If they're careful, they can sometimes make the drive work again instead of making it unfixable at all (at least not fixable in a practical sense).
Good hint for the savvy owners of out-of-warranty equipment. (That should be plumb, not plum.)
Holy Cow! My drive had not played DVDs for some time now. Compressed air didn't help. Just now it spit out a DVD, did one swipe with an eyeglass cloth, reinserted AND I'M WATCHING A MOVIE!
It is obviously a risky thing to do, but it was worth a try before buying a replacement drive at $100 for a very old laptop (2006 MBP).
Thanks!

I had found this hint elsewhere (can't remember where) quite some time ago and it has served me well. Sadly, my SuperDriver eventually stopped reading disks altogether so I replaced it. But this hint definately made the drive usable for a few years after I first noticed the problem.
The DVD cleaner discs work well with dusty drives too. I have a Macbook pro that was in same situation. I put in the DVD cleaner and it started working again. The DVD cleaner disc actually has little bristles right on the discs surface that brush the lens as it searches the disc. But in a pinch I can see how this might work.
Thank you for the idea. I actually managed to clean my 1.5 year broken SuperDrive in early 2009 MacBookPro with glasses cleaning cloth and a business card ;)
Nice to know, but I prefer to open up the drive and clean it this way. Of course it’s a little bit more work, because you have to open your Mac, but you can directly clean the lens this way without fear of destroying the drive. Here’s a good example: http://muzso.hu/2008/08/17/how-to-clean-the-lens-of-a-slot-loading-optical-drive-a-macbook-pros-superdrive
Internal Mac Dvd Drive
I did this.. I cleaned the lens using alcohol. Unfortunately it didn't helped at all. DVD's are still working but not CD's.. Those superdrives are really a piece of junk. Mine stopped working after one year.
Cd Dvd Drive Cleaner
I did this and everything worked fine afterwards. Before the cleaning it would neither read nor burn CDs and DVDs.

Worked first time. Many thanks.
Holy crap it worked. My mini would burn CDs under Lion and Mountain Lion, but then not recognize them. This trick is brilliant.
