My mac pro has no sound, all is on. isthere a mute i don't know about?

my mac pro has no sound. don'yt know what i did. is there a mute i don't know about? was wking fine.

F10 is usually the function key on MacBook Pro's. You might have accidentally touched it. Hit it again, and the sound will return.
Also, I hope you're not actually using OSX 10.5.1. You should get all the security and performance updates to protect your Mac.

Airplay via Mac Pro has no sound.

Picture good but no sound when using airplay via mac pro.

If the sound comes out of the Macbook Pro instead of the Airplay receiver:
Hold the Alt key, select the sound icon in the top menu bar (next to the wifi icon), and select the Airplay Receiver (Apple TV or other)
If there is no sound at all, check the sound of the Apple TV (or other) without using airplay.

My mac pro has no sound, only extern connection can to reproduction sound

somebody knows what's problem? what can i to do?

Do ear phones work? If so look in the audio output port. If there is a red light, the internal switch is stuck.
Insert the earphone jack several times.
Blow real hard into the port.
Take a tooth pick and jiggle it inside the port.
If no success, bring it to an Apple store.

MacBook Pro has no sound at all. Called Apple and they said to reinstall OS X.

I have recently discovered that my MacBook Pro has no sound except for the startup chime. I called Apple and they told me to reinstall OS X because something went wrong in the OS. Is there any other way to fix this?

That's a really overly simplistic answer to your problem. Re-installing OS X doesn't always fix every problem. Yes, it might in your case, but it might not. Are you still under warranty? Either way, I'd take it into your local Apple Store and show them the problem and let them fix it. If the system has to be installed anew, so be it. But rule out other problems first.
Before you do anything, make sure that you have a back-up of your data, applications, etc. If you don't already have a back-up scheme, get an external hard drive and use Time Machine to back up your computer. Then take it into the Apple Store.
Good luck,

Mac Pro has slowed to a crawl - Please Help Me!

Hello,
For some time now my Wireless or Wired Internet connection using my Mac Pro has slowed to almost nothing. For example, This page took 5 mins to load and now Internet use has become unusable.
I feel its my Mac Pro because all other Apple Computer run very fast wirelessly. I have (2) New iMac's (1) Apple TV and (1) Apple iPhone. All stream and surf the Internet blazingly fast.
My Mac Pro is constantly being redirected to other sites (mostly **** related) and a huge amount of Pop ups (even though pop ads are disabled in Safari). All Internet browsers perform the same on my Mac Pro or ANYTHING Internet related including WoW, Software updates or even iTunes Music Down loads.
I really feel that in some way (which is shocking) I am infected with "something" that is making my computer crawl on the Internet. Redirection of websites is just now very aggravating.
I am looking at the (2) Original Disks that came inside the Mac Pro Box. I'm seriously considering wiping my system clean and starting from scratch.
I currently hold NOTHING on my Factory 320GB HD other than programs.
I have installed (2) 1TB drives and created a RAID slice thus creating a single HD icon on my desktop that reads 1.8TB. Thats is where all my Music, Photos, and Movies reside.
My question is....
When I wipe my system will that RAID be broken? Will I lose everything on those 2 drives or will using the restore CD's leave all that information in tact?
Please let me know before I proceed.
Thank you for your time.
John

Your RAID won't be touched. But back it up today if you haven't yet!
I use Firefox for security with noscript and some other filters, but I also hardened the router firewall to manually block services, ports and add rules - both incoming and outgoing.
You might want to look at LittleSnitch or NetBarrier and do some logging.
I've seen/heard where older routers and modems were fine, but not with Mac Pro or with Intel Macs in general and needed to be replaced or firmware updated. Problems with the latest updates for Airport have been seen by some, and worth checking into - on forums, news sites or hit google.
And of course check what processes are getting loaded and run; manually delete caches, history, metadata, even the bookmarks cache.
~/Library/Caches/Metadata
There are issues with fake Flash updates; normal sites (like CNN) suffering from SQL-injection. Best to run with javascript off for now.
Might want to look into ClamXav and other malware protection. But I would switch and see how Firefox and Opera behave. And turn off java, script, and plug-ins while you consider your options and try to find out why.

My mac pro has died, how can I see my emails on my macbook

My Mac Pro has died. I intend to get it repaired, obviously, but I need to see my emails from the many years of emails archived on its undamaged hard drive. I have removed the hard drive and connected it to my macbook using a USB carrier. I can find myself under the users, but the library file where the mail folder is kept remains hidden, so I can't copy it across.
What can I do to get my emails useable again immediately?
I posted this before but on a Macbook discussion and got no useful reply.
It surely is possible to do this isn't it?

In Finder select Go, then hold the option key.
You will now see Library. Select it and navigate to Mail.
emails are in V2 Folder
See eric's suggestion to "check ’Show Library Folder’"

To keep it seperate from the Mail already on this Mac, I would set up another user account (->System Preferences->Users & Accounts), and then log into the new account. Quit Mail, Delete ~/Library/Mail in the new account and copy Mail from the other Mac.
Delete these files to force a re-index:
Open Mail

Memory Leak in Mac Pro. My Mac Pro has 16 GB memory

The memory (as shown in the Activity Monitor) goes from a high of approximately 11 GB free memory to a low of approximately 50 MB. The leaked memory seems to be going to "Inactive". When the memory is on the low end, the Mac Pro is very slow, sometimes freezing for several seconds. Does anyone know what the problem could be?

An update to my original discussion message. Now the Mac Pro has some extreme lag times when accessing programs, deleting files, copying files, etc. This occurs even when the free memory as shown in the Activity Monitor is high (over 8 GB). If anyone has an idea of how to correct this problem, please let me know.

We recently had a few brief power failures. Since then, my Mac Pro has been very slow on start up. Any suggestions?

Like the man says:
Run Disk Utility > Repair ... (not just repair permissions) while booted from another drive. If you have a stronger utility like Disk Warrior, that would be even better.
If you find that the ONLY way you can do this is by booting from the DVD, The Hatter recommends you establish an emergency drive or partition on a drive other than the Boot drive and use that in the future. It makes emergency Repair, backup, and cloning much easier.

Thanks for any help!

try runniing Apple hardware test
reseat risers and dimms
test wtih half memory
do not use your normal system for now - it is probably corrupt and can lead to more issues
try a clean system w/o any 3rd party anything, divers, cables, devices
rather common for fb-dimms to fail and go bad, luck, other than apple, they carry lifetime warranties

Mac Pro has slow boot time

help! i actually have the same issue after disk recovery with mavericks, i changed my system drive to ssd. everything else works perfectly, but the boot time is more than a minute.
as soon as i press the power button, the sound goes, and a black screen will stay for about 10 seconds, then the white screen appears and lasts for about 45 seconds and as soon as the apple logo comes, it takes about 10-15 seconds only. I tried everything from resetting NVRAM and SMC, indicating the ssd as the startup disk, (i thought that would solve the problem for sure) and the like. everything works perfectly except for the boot time which is much slower than my original 7200 rpm drive.
i really do not want to do a full reinstall of my software because initializing would probably take a day or two, and i have lots of deadlines. is there something else i can try?
i'm using a mac pro 4,1 (early 2009) and using mavericks 10.9.2. 16 gb ram
<Subject Edited by Host>

Are you speaking of a Mac Pro or a MacBook Pro? A 4,1 MacBook Pro can handle up to 6GB of RAM. I don't know about a Mac Pro - the is the MacBook Pro forum. If you need information about Mac Pros, see -> https://discussions.apple.com/community/desktop_computers/mac_pro.
Good luck,

Early 2008 mac pro has an infrared sensor?

early 2008 mac pro has an infrared sensor?

okay-what, am I a salesperson now? dunno why you can't google it yourself, or get me a job doing this (just kidding--sorta)
anyways, you could try either twistedmelon or a bluetooth presentation remote (targus or Kensington,maybe logitech.
I think i've done enough here....just fyi, bluetooth on a mac pro desktop isn't great....
getting a dongle for that might be helpful.....

It's not your wording that's at issue. It's the incorrect information you provided. Go back and read my reply.
I'm sorry but I can't help your mis-wording. I can only make sense from what you have written. Your location is the UK so I must assume English is your first language without other information to go by.
If you wrote the same thing a hundred times in one day, then you'd use copy and paste, too. So don't insult those of us who do.

My late 2013 Mac Pro has a dust problem, any help?

My late 2013 six core Mac Pro has a lot of dust within it and it is bugging me. Is there a way i can clean it or sort it out?
Any response with be well received!
Thanks in advance

I have two cats that shed very fine black fur. After a couple of weeks of use, I noticed a build up on the intake slots of my Mac Pro (late 2013).
1. cut a piece of 1/4" hardboard / mdf / plywood into 7" circle.
2. get some very fine mesh, 'no-see-um' screening. Cut a piece into a 12" circle.
3. lay the screening on the table, lay the mdf in the middle of the screening, set the Mac Pro in the middle of the mdf.
4. stretch a narrow rubber band around the Mac Pro, just below the connector cut out
5. working around the Mac Pro, pull a portion of the rubber band away from the Mac Pro, tuck in the screening, until the whole outside edge of the screening is under the rubber band
6. the slightly larger diameter of the mdf circle keeps the screening away from the Mac Pro intake slots
Every couple of months / weeks vacuum the screen.

My mac pro has no sound, all is on. isthere a mute i don't know about?
