• No sound optical input on Mac Pro

  I'm working on some problems with my optical sound system, and I have a recorder DAT Sony outlet in my Mac Pro, Late 2010 5.1 Sierra running. I bring the signal of the DAT, via an optical cable in the Mac - I get a visual cue on the sound preferences - but not his actual computer, any output, I try: internal spkrs, Line out, Digital out, bar his monitor, or Bluetooth headset. That is what it is? I trashed preferences sound and zap the PRAM. No change.

  Hmm... It is of course odd. If you hold down the option key and click on the speaker at the top of the screen icon, you should see a list of all the available audio inputs and outputs, you can also find it under system preferences > sound

  other this, try to pull the Audio high noon and see what she has set, sometimes, strangely enough, IT Gets the value to something weird like 96 khz or line output, or some of these.  except that, depending on the application you are using, you may need to edit the record source and to ensure that play through is committed. your device should appear if all goes well. I think it must be configured as 44 kHz or 48 khz

  Sorry I can't be more helpful

• Mac Pro Sound cutting in and out

  I just got a new Mac Pro (OSX 10.11.6) (3.7 Ghz Quad Core, 16 GB of Ram, Dual AMD D500 GFX, 500 GB Solid State Drive)

  When video editing in Premiere Pro and sometimes listen to music in Google Chrome, the noise stops.  And it seems to be a bit random and sometimes simply minimize windows and change windows sound coming back.  I've dealt with it for a week now and can't really nailing a model, but it seems that if I switch to a different app and use it for a while and go back to Premiere Pro the sound sometimes works again.  This seems to happen in Google Chrome while listening to pandora when I adjust the volume of the sound will just completely disappear for a time seemingly random.

  Also, I'm quite surprised by the slowness of the system seems to be.  Maybe my expectations were off line, but for a 4 000 dollar computer I expect quite easily handle HD videos.  I'm from a Canon C100 video editing and it's quite ordinary 1080 HD video and preview is set to 1/4 resolution, and the system is really slow.  It seems to fall 70% of executives in the Preview Panel and any action I take have as a half second delay on this.  Is this normal?  I have a personal computer at home that I built to about 1 k and do that kind of thing, no problem.

  I appreciate of course any help you guys can provide.  I need to get this stuff flattened and so I can get some work!

  See if a Safe Mode speeds up your Mac a little. Remove the system caches that could make a difference.

  Follow these steps to start in safe mode.

  1. Start or restart your Mac.
  2. As soon as you hear the startup tone, hold down the SHIFT key.
  3. Release the SHIFT key when you see the logo Apple appears on the screen.

  After the Apple logo appears, this may take longer than usual to reach the login screen or your office. This is because your Mac performs a check of directory of your drive to boot in safe mode.

  To leave safe mode, restart your computer without pressing any keys during startup.

• Installation 10.11.6 El Capitan with 10.6.8 Snow Leopard on old Mac Pro 4.2 multiboot?

  Looking for savvy here advice...  I have an old Mac Pro 4.2 (cheese grater) that runs Snow Leopard 10.6.8.  It is a wonderful workhorse machine, who served me tirelessly for many years.  It is obviously older and slower, but works very well.  I love 10.6.8.  If Apple ever updated the Mac Pro line (I know, probably not... sigh...), I'll buy one and replace this machine.  Until then, I keep doing this work.

  This machine is a beast, has been upgraded with internal hard drives 1 TB three (he also got a couple internal HDs inherited from 750 and 500 MB used for storage).  I have also several external 1-4 to, hip, FW800 drives too.  A host of storage, of course, and should be a lot of options to start on several systems.

  I am generally satisfied with 10.6.8 on this machine, although there are obvious limits to that.  I would get one or two operating systems newer on it, pick-and-choose between them according to the needs, but I absolutely want to/need to preserve the ability to initiate and run 10.6.8 systematically as my operating system on the day the day, at least for now.  Maybe I'll warm to one of the others on this machine eventually, but 10.6.8 must remain usable, install a newer OS on other readers may not nerve there.

  On a year-and-a-half ago, I took a race to install 10.10.3 Yosemite on one of the internal disks.  This doesn't quite work.  I moved, sniffed Yosemite everywhere, don't really like it a lot and went to restart and him switch back to 10.6.8 for a bit.  Initially, it was impossible (from less than I expected, would be the same old process, I have always used, via system preferences > startup disk).  You can read the details of this experience here and more here if you are interested.  This latest attempt to get Yosemite on this machine was a very negative experience.  Yosemite is still there on an internal HD, but I tried not to boot on it since then.

  Now I take another look at this.  What is the engine now, is that I want to update my iPad Mini 3 iOS 10.  But that (update of an iDevice iOS 10) requires iTunes 12.5.1.  And iTunes 12.5.1 requires Mac OS X 10.9.5 or newer - it won't work with 10.6.8.  I'm looking for my options.

  Right now, I have three large internal HDs: HD #1, 2 # HD and HD #3, each 1 TB.

  HD #1 has 10.10.3 Yosemite on this.  I started from this time and have not resumed since.

  HD #2 has 10.6.8 Snow Leopard top.  This is my main operating system and startup of daily drive.

  HD #3 is nothing special about it.

  Although HD #1's Yosemite about that, I have only started from this disc once and hesitate to go back, at least until I can get a way easy and reliable to restart off HD #2.

  I understand that I can also get 10.11.6 El Capitan.  I thought that installing on HD #3.  That sounds like a reasonable to add option, but again, I want to make sure it won't cause problems to switch back to start off HD #2 in Snow Leopard (such as installation of Yosemite on HD #1).

  What is the best way for me to go about safely - preserve the option to start easily in 10.6.8 on HD #2?

  Thanks for the help!

  If you start or restart now Option (Alt) key and calls the Startup Manager, you should be given the choice at the start of any boot disk OS X on any of the readers.

• Mac Pro equipped with graphics cards

  (1) Apple certified repair done remarkable work or replacement of these cards, seemed as it did thousands due to schools, universities, colleges had all the problems that I did.

  (2) now did the-d option to initialize the data sent to Apple and have assigned Senior Adviser.

  (3) most recent problem is error codes and system dead slow on my second Mac Pro 6 hearts. Now, does not see my Amd hardware, which is extremely strange to say the least.

  (4) 2 weeks no words or calls returned Senior Advisor, still more serious delays to write make some income with new Mac Pro.

  (5) what did not work is not, the example is iMovie stutters sound.

  (6) final Cut Pro sound of of synk

  (7) k video from my new iPad Pro 4 who made 4 K video sent to dump not recognized on Mac Pro system after that reminder of graphics cards has been made.

  so waiting for words from Apple on the d option played 4 times.

  < published by host >

  Nope... but... all I can do is give you my experience. I got a G5 liquid that had major failure 3 times (was under AppleCare) and has been replaced with a Mac pro. I guess you have tried the usual, killer stuff pram resetting the PMU, trying to reinstall and update the operating system and various applications to this topic and all that, and... nothing. Apple does not read or respond to these forums, cmdrDenis, this place is strictly a user forum, and that's all. Save all your receipts, paperwork, document as much as you can and when you talk to Apple or an adviser, be polite, but pragmatic.  Screaming, yelling, Ranting and raving you will get very far.  If you go to apple.com/feedback and leave a comment there, someone can get back to you. Call the main line from Apple can be useful too, but about what, when and how

  I can't say. Apple * may *, in its sole discretion, replace a machine that has had too many major repairs, or repair, but it's Apple to do.  Maybe if you call your local Apple place, explain the situation calmly and kindly and ask to speak to another senior consultant or Manager, perhaps they can help you.

• Mac Pro RAM, Audio, Bluetooth mouse problems

  I recently bought an Apple factory refurbished Mac Pro (end 2013) and replaced the three-chip RAM of 4 GB with 16 GB of Crucial two chips. Everything was great for the first two weeks. Then I started having a strange audio problem. Audio would become suddenly agitated. I disconnected and reconnected the speaker output and it would start working again. Finally, unplug the unit and plug the unit has stopped working (audio would eventually just stop working completely... zero sound with or without the speaker plugged in...) and I had to restart the computer.

  Then one day I noticed that only 16 GB of RAM showed up (I run own memory, so he's in my toolbar). I opened the machine and moved the two chips on the other side and when I rebooted, I got 32GB again.

  Then I noticed that when the audio problem came once again (he seems to be after the computer has been for a few hours or more) my Apple bluetooth mouse would disconnect and reconnect intermittently... ONLY when the audio starts to get restless again.

  I zapped the PRAM several times and now I get the 32 GB of RAM only after disconnecting the chips and MOVING them to another location, but not all the time. The audio port will begin to spoil, I reboot and I'm back to 16 GB.

  So, is it bad RAM? I removed a single chip and the audio problem still happens.

  Anyone have this problem? Apple Care suggested I bring it in the Apple Store, but I thought that I ask here before go this road, just in case there is a known issue.

  Thank you!!

  Rick...

  To establish if it is a RAM problem, remove 16Bb sticks and replace the original 4 GB sticks.

• Freezing / sluggish: Logic Pro 9. Mac Pro; Yosemite

  As the title suggests, I am experiencing sluggish controls and performance in reading with Logic Pro.  My specs are:

  Mac Pro (round) mid-2010; 2.8 GHz Quad Core (Intel); 12 GB OF RAM

  10.10.5 Yosemite

  Logic Pro 9.1.8

  Everything is apparently fine with the performance, however, I randomly and almost inevitably experience the app 'snap '.

  Never quite completely, it freezes, will get rather unresponsive in functions such as when I'm in the reading, he will just continue to play while any activated button will be delayed for a few seconds until the number of seconds before he answers.  This does not happen with the launch at the beginning of a session and a cool app, but wire time, it will be unless I have close / restart the application.

  I recently created a new installation of Yosemite on his own internal drive - using a stock of Apple HD (Western Digital, Black Label, 1 TB, 7200 RPM)

  The only thing installed on the OS drive is Logic Pro and a few plug-ins.  I watch performance monitors, nothing appears close to overload (this is both logic and Universal Audio monitors CPU usage).  My sessions are not complicated: consist on average of about 4-5 stereo Audio tracks / track Instrument 1-2 / 2-4 Bus titles.  Plug-ins averaged around 2-4 per track.

  I use a writing another drive internal (2 TB) and save the files of session while recording / mixing.  My plan was to spend the end sessions at the coast by car after completing their but I suspect that it is the source of performance problems.

  My question is, I'm pretty committed to get an upgrade of RAM max (32 GB for my system).  I hope that this will add enough buffer space to avoid blockages in the performance.

  • It is, 12 GB sound like a stretch to try to run the logic without any problems?

  • Would a 32 GB upgrade be important?

  • Logic Pro (9) have known problems with hang up and becomes unresponsive / slow over a period of time with a running period session continues?

  • Any other use?

  • Is it I better off working on and recording of current session to the local operating system drive rather than another drive?

  In fact... I think you will find that much of this is related to graphics performance. Are you running one of the EQS of channel mode Analyzer, medium or hi res? This will certainly lead to delays, even if they are not displayed. Logic 9 graphics routines is quite old and showing their age with newer operating systems. Using a dual monitor system (display)?

• Mac Pro 2009 will not start, no edge

  On Thursday, June 16, I sat to use my Mac Pro early 2009. I noticed that my Mac would not wake up by mouse click or the SPACEBAR on the keyboard. The led on my Mac, so I immediately thought that it was a problem with the graphics card.

  I force shut down the Mac by holding the power button. I waited 10 seconds and turned on my Mac back, everything was fine and I worked on my Mac for 3 hours.

  Last night 18 June I sat watching television when I heard the ringtone on my Mac Pro, I realized was a reboot. I went to the wire and connected and everything seemed fine. However later in the evening, I noticed a flashing LED on one of my two monitors. Once the Mac was on (fans spinning) but no signal to the monitor.

  I made another force off now the power button on Mac, but now when turn on the Mac there is no boot chime or control signal.

  I upgraded the graphics card to an AMD Radeon Sapphire HD 7950 in April 2013.

  Any advice would be much appreciated as I'm in the middle of a big project.

  Could also be a Mac Pro RAM chip inyour failure, sounds almost identical to a question I've had recently, I found the missing question when I removed the memory card.

  If one of the pair of cards, you will need to remove two cards.

  Try taking the memory OUT n test each module one at a time. Also check RAM editing maps, if none of the four lights on the two cards is turned on it idicates a defective module.

• Mac Pro randomly turns itself off (again)

  Mac Pro randomly turns off by itself

  I have never got rid of the problem. Even after having replaced my card stock (radeon 5770) display with Asus Strix GTX 980 Ti, used a Corsair CX750 only power supply to power it. Look like anything, it's over heating, im stimulate fans PCI, exhaust and intake to 2500, 2000 and 2000 RPM (respectively). his strong!

  I'm tired of dealing with this old-tech, unreliable, expensive, overrated,... flat of the weight of the aluminum foil, so please find me a real solution/fix! I could easily put together a very decent PC that 'JUST WORKS' from what ive already spent trying to fix it.

  whenever he stops, I hear a click from the PSU (similar to the clicking sound when you press the power button on the front, commissioning). Trying next turn to the after he died, sometimes the power button will not turn on right away. I had to wait at least 10-15 sec to make it work. When it works sometimes stop with click 2 to 5 seconds after pressing the power button. He sometimes dies right after the chime. It starts also through without any problem.

  A few times when sometimes I watch the LED at the front of the Board (opposite the PCI fan) when he died, I see the two top LEDS blink once I hear that click, those who are highlighted red in the picture (not a picture of my Mac real). It also sometimes flashes when I press the button boot but used to power upward after that he died. Please, what that means?

• Big screen for the new Mac Pro

  Looking to buy a new Mac Pro.  I like to work while sitting on the couch with my feet supported, but a laptop is not very good for usability, and my neck has had enough.  So, I think trying to upgrade a number of things and to combine the entertainment center with work stations, so I can do both comfortably from my couch.  Ideally I would love it if Apple made a gigantic Retina display, but as they do not have, my current theory includes a 48 "-52" class 4 K HDTV connected to a surround sound via HDMI system, which hangs in turn a blu - Ray player and a Mac Pro via HDMI.

  If someone has done something similar?  I'm assuming that, unlike the old flat screen TV model at work sometimes I mirror my iPad on, a 4 K Pixelize text.  Is this correct?  Or should I still the same problem?  As far as the projectors are a pain, which is the only really good solution here?  Any other question, I would need to know that displays the parameters or incompatibilities if I went with the 4 K HDTV?

  May be useful to take a look at http://www.macrumors.com/guide/4k-5k-displays-buyers-guide-mac/ which covers the 4 K screen with Apple hardware support pretty well.

  You will encounter one of the limits is the HDMI output on the current Mac Pro supports only 4K at 30 Hz not full 60 Hz, which we are used to on most screens. You can watch a form of Thunderbolt to the HDMI connection for display to work properly at 60 Hz.

• How do I get the normal home screen on the Mac Pro?

  I upgraded the graphics card in my 2008 Mac Pro, which has also bootcamp, but now when I want to switch it to Mac OS X I have graphics cards, boot in OS X with my OS X disk selected, restart and then it will stay, instead of being able to hold down the option key pressed during boot to get the drive selector. Is there a file I can change so that I get the Apple boot screen and the drive selector?

  Sounds like replacing the graphics card is a regular PC and not a Mac-Flash card. Only one Mac-Flash card will show a splash screen and allow the use of the Option, special recovery and other startups.

  Some mac-flashed it maps to select the PC or Mac equipped with a switch mode

  Do you have what graphics card installed?
