What cable do I need to run a slide show with music on a projector at a meeting? I have a Mac Book Pro.

Hi jackwyatt,
Thanks for visiting Apple Support Communities.
If you would like to connect your MacBook Pro to a projector to output the display and sound, the cables and adapters you need will vary depending on the specific model MacBook Pro that you have.
I recommend this page for getting a good idea of which adapters you might need:
About Apple video adapters and cables
Additionally, the tips in this article can also apply to using a projector as a display:

All the best,
Jeremy

I have a mac book pro with Boot Camp that also runs windows. I upgraded to Lion and somehow it crashes the mac side peridoically. I am told I need to "clean" it and reinstall lion using the recovery drive. will that delete the windows partition too??

I have a mac book pro with Boot Camp that also runs windows. I upgraded to Lion and now the mac side crashes/freezes periodically, especially iphoto. I am told by the genius' that I probably need to "clean" it and reinstall lion using the "recovery drive" which resets everything back to default and reinstalls the lion operating system. My question is will this also delete the "windows" partition drive and all that data too. If so that will be a huge pain in the ___ to back up and reinstall boot camp and windows. I want to shoot the lion.

There is no system like Acronis for the Mac platform. You can try using the buiilt in Disk Utility to create an Image of the complete Mac drive but I have found that this does not work very well as on tryiing to restore it gives errors sometimes.
You can use SuperDuper or Carbon Copy Cloner to create a bootable Clone of your system partition. But that is only for the System partition and not the complete drive.
If you use Boot Camp to install Windows on your Mac neither of those two programs will clone the Windows side.
Neither will Disk utility as Mac's can not create or write to a NTFS partition. So some other program is need for that.

I'm trying to share to Media Browser a 20 minute still slide show with music and text. I have tried several times to save at 1080 HD, but just before it's finished, a message box pops up saying "File already open with write permission." What's this mean?

I'm trying to finalize/share to Media Browser a 20 minute still slide show with music and text. I'd like to finalize it 1080 hd and have tried several times, but just before it's finished, a message box pops up saying it can't be done because "File already open with with write permission." What does this mean? All files are closed; this iMovie project is the only thing open. Does it mean one of the song files from iTunes? And should I just settle for saving it as a "large" file, which is what I'm trying right now?
Thanks,
Jamie

System Software Version : OS X 10.9.5 (13F34)
Kernal Version: Darwin 13.4.0
Boot Volume: Macintosh HD
Boot Mode: Normal
Secure Virtual Memory: Enabled
Regarding the Macintosh Hard Drive:
Available space 208G.66GB , Capacity 499.25GB
Intel 7 Series Chipset, Link speed 6 Gigabit
Apple HDD Toshiba MK5065GSXF, Revision GV201B
Using Kodak ESP Printer 5200 Series AiO
Memory slots Bank0/DIMMO 2GB DDR3 1600MHZ and BANK 1/ DIMMO 2GB DDR3 1600MHz
The problem I am experiencing is a slowness of response between changing from various applications. What steps could I take to clean up the boot speeds, the applications speeds and general performance of the computer? I would like to restore the speeds of that when it was new.
Thank you for any suggestions you may have.

I have a problem with iphoto (have a mac book pro): the icon in the dock appears with a question mark, and the application is gone!!! Can someone tell what's going on? Yesterday I had the same problem with itunes: I downloaded the last version (it's free), but I cannot do the same with iphoto, and more important: I need to know what is happening!!! Please help me!

Applications should not disappear all by themselves.
If they are then that coud indicate serious problems with your hard drive.
Backup everything up as quickly as possible.
Using Disk Utility verify your system disk.

You may have installed the "DownLite" trojan, perhaps under a different name. Remove it as follows.
Malware is constantly changing to get around the defenses against it. The instructions in this comment are valid as of now, as far as I know. They won't necessarily be valid in the future. Anyone finding this comment a few days or more after it was posted should look for more recent discussions or start a new one.
Back up all data.
Triple-click anywhere in the line below on this page to select it:
/Library/LaunchAgents/com.vsearch.agent.plist
Right-click or control-click the line and select
          Services ▹ Reveal in Finder (or just Reveal)
from the contextual menu.* A folder should open with an item named "VSearch" selected. Drag the selected item to the Trash. You may be prompted for your administrator login password.
Repeat with each of these lines:
/Library/LaunchDaemons/com.vsearch.daemon.plist
/Library/LaunchDaemons/com.vsearch.helper.plist
/Library/LaunchDaemons/Jack.plist
Restart the computer and empty the Trash. Then delete the following items in the same way:
/Library/Application Support/VSearch
/Library/PrivilegedHelperTools/Jack
/System/Library/Frameworks/VSearch.framework
Some of these items may be absent, in which case you'll get a message that the file can't be found. Skip that item and go on to the next one.
From the Safari menu bar, select
          Safari ▹ Preferences... ▹ Extensions
Uninstall any extensions you don't know you need, including any that have the word "Spigot" or "Conduit" in the description. If in doubt, uninstall all extensions. Do the equivalent for the Firefox and Chrome browsers, if you use either of those.
This trojan is distributed on illegal websites that traffic in pirated movies. If you, or anyone else who uses the computer, visit such sites and follow prompts to install software, you can expect much worse to happen in the future.
You may be wondering why you didn't get a warning from Gatekeeper about installing software from an unknown developer, as you should have. The reason is that the DownLite developer has a codesigning certificate issued by Apple, which causes Gatekeeper to give the installer a pass. Apple could revoke the certificate, but as of this writing, has not done so, even though it's aware of the problem. This failure of oversight is inexcusable and has compromised both Gatekeeper and the Developer ID program. You can't rely on Gatekeeper alone to protect you from harmful software.
*If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combination command-C. In the Finder, select
          Go ▹ Go to Folder...
from the menu bar and paste into the box that opens by pressing command-V. You won't see what you pasted because a line break is included. Press return.

I have a mac book pro osx 10.7.5. Do I need to get anti-virus security software

I have a mac book pro osx 10.7.5. i do not have a virus checker. Do I need to get anti-virus security software that will protect against the new virus? And what would you recommend.
Thanks

There will always be a "new virus". Is this the recent threat you are concerned about?
http://www.bbc.com/news/technology-27681236
It only affects Windows PCs, which is usually the case.
have a mac book pro osx 10.7.5. i do not have a virus checker.
Those two statements contradict each other. OS X 10.7.5 already includes everything it needs to protect itself from viruses and malware. Keep it that way with software updates from Apple. Installing third party "anti-virus" software cannot possibly protect you from all threats, whether they exist today, or may occur at any time in the future. Such products are far more likely to cause random instability, crashes, loss of data, time, money, or all the above, while providing nothing other than a misplaced sense of complacency - a threat all to itself.
The sky is perpetually falling for so-called "news" outlets. It has been so for many people since the beginning of time, and it will remain so for all eternity. Don't confuse fearmongering with becoming informed.
A much better question is "how should I protect my Mac":
Never install any product that claims to "speed up", "clean up", "optimize", or "accelerate" your Mac. Without exception, they will do the opposite.
Never install pirated or "cracked" software, software obtained from dubious websites, or other questionable sources. Illegally obtained software is almost certain to contain malware.
Don’t supply your password in response to a popup window requesting it, unless you know what it is and the reason your credentials are required.
Don’t open email attachments from email addresses that you do not recognize, or click links contained in an email:
Most of these are scams that direct you to fraudulent sites that attempt to convince you to disclose personal information.
Such "phishing" attempts are the 21st century equivalent of a social exploit that has existed since the dawn of civilization. Don’t fall for it.
Apple will never ask you to reveal personal information in an email. If you receive an unexpected email from Apple saying your account will be closed unless you take immediate action, just ignore it. If your iTunes or App Store account becomes disabled for valid reasons, you will know when you try to buy something or log in to this support site, and are unable to.
Don’t install browser extensions unless you understand their purpose. Go to the Safari menu > Preferences > Extensions. If you see any extensions that you do not recognize or understand, simply click the Uninstall button and they will be gone.
Don’t install Java unless you are certain that you need it:
Java, a non-Apple product, is a potential vector for malware. If you are required to use Java, be mindful of that possibility.
Java can be disabled in System Preferences.
Despite its name JavaScript is unrelated to Java. No malware can infect your Mac through JavaScript. It’s OK to leave it enabled.
Block browser popups: Safari menu > Preferences > Security > and check "Block popup windows":
Popup windows are useful and required for some websites, but popups have devolved to become a common means to deliver targeted advertising that you probably do not want.
Popups themselves cannot infect your Mac, but many contain resource-hungry code that will slow down Internet browsing.
If you ever see a popup indicating it detected registry errors, that your Mac is infected with some ick, or that you won some prize, it is 100% fraudulent. Ignore it.
Ignore hyperventilating popular media outlets that thrive by promoting fear and discord with entertainment products arrogantly presented as "news". Learn what real threats actually exist and how to arm yourself against them:
The most serious threat to your data security is phishing. To date, most of these attempts have been pathetic and are easily recognized, but that is likely to change in the future as criminals become more clever.
OS X viruses do not exist, but intentionally malicious or poorly written code, created by either nefarious or inept individuals, is nothing new.
Never install something without first knowing what it is, what it does, how it works, and how to get rid of it when you don’t want it any more.
If you elect to use "anti-virus" software, familiarize yourself with its limitations and potential to cause adverse effects, and apply the principle immediately preceding this one.
Most such utilities will only slow down and destabilize your Mac while they look for viruses that do not exist, conveying no benefit whatsoever - other than to make you "feel good" about security, when you should actually be exercising sound judgment, derived from accurate knowledge, based on verifiable facts.
Do install updates from Apple as they become available. No one knows more about Macs and how to protect them than the company that builds them.
Summary: Use common sense and caution when you use your Mac, just like you would in any social context. There is no product, utility, or magic talisman that can protect you from all the evils of mankind.

The Apple Support Communities are an international user to user technical support forum. As a man from Mexico, Spanish is my native tongue. I do not speak English very well, however, I do write in English with the aid of the Mac OS X spelling and grammar checks. I also live in a culture perhaps very very different from your own.

Erase and Install
1. Boot from your Snow Leopard Installer Disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed.
4. Quit DU after formatting completes and return to the installer. Install Snow Leopard.
5. After restart into Snow Leopard download and install Mac OS X 10.6.8 Update Combo v1.1.
