Mac Pro (bluetooth problems)

Hi all, I hope a genius can help...
I have a usb bluetooth dongle attached to my mac, which has been working previously for over 2yrs, only recently I am having problems, every time i switch off the mac and turn it back on the bluetooth is switched off.
the only way i can seem to turn it back on is by..
right clicking on a file > more > send "*" to bluetooth device then cancell that and a another window will pop up saying turn on bluetooth,

I'm having similar problems with a brand-new Mac Pro 8-core. Mouse cuts out (I'm using a wired keyboard thankfully) and my Jawbone headset will work wonderfully with my old MacBook Pro but will only pair (maybe) on my Mac Pro.
Called and spoke with an expert and feel I get the run around. He had me shut down and unplug everything for 30 seconds. I did it but felt he was just having me "do something" to get me off of the line.
Apple has a problem with Bluetooth on their Mac Pros and isn't dealing with it.

Can my mac pro Bluetooth talk to my new ATV using Bluetooth to send slideshows

Can my mac pro Bluetooth talk to my new ATV using Bluetooth to send slideshows, music and movies

You know you don't have to buy a replacement dvd drive from apple. For example, take a look at OWC's selection.
You don't say what year your mac pro is so I use a 2008 as an example. On that page click the little picture that shows a 2008 mac pro. That will take you to this page. And there's an example of a Lite-On drive.
In addition, on the right side of that page are links to instructional videos on how to add the drive to your machine. Click, for example, Optical, med (medium) and you will see how straight forward it is to change the optical drive.

Lacie Speakers and Mac Pro Firewire problem waking from sleep and loud feed

Lacie Speakers and Mac Pro Firewire problem waking from sleep and loud feedback. I had a powermac before this with the speakers and it worked fine. But the mac pro is having these issues. Is it the firewire port or the speakers or (and most likely) just a firmware glitch with mac pro? Anyone else see these issues?

Here is my audio settings. For some reason I wish I could remember what I did. It was actually the Apple Store tech in the Unversity Village in Seattle that gave me the idea and I swear I had to change the settings in MIDI setup. Now that Leopard is out it seems the MIDI stuff has been redone. I included screenshots of my MIDI setup as it is currently to see if you see something different on your computers. Let me know!

Mac Pro Fan Problem

Hi, I have been having some problems with a Mac Pro I have been working with. At the Start-up the Fan goes to top speed and once it logs-in the fan is still pretty loud. I've checking the Temperature of all the computer parts via a Temperature Diode, and its normal and not high. After searching the internet for hours looking for posts that were for the Mac Pro and not for the MacBook Pro (which comes up in about all the searches using the words Mac Pro Fan Problem) and I found some software all of which is not for Mac Pro's. Is there any application I can run do reduce the RPM of the Fans, Reset the Fan Speeds to only turn on when it get hot, or something along those lines.

Thats odd, seeing as Apple have it listed in the Support article:
To reset the SMC on a Mac Pro:
1) From the Apple menu, choose Shut Down (or if the computer is not responding, hold the power button until it turns off).
2) Unplug all cables from the computer, including the power cord and any display cables.
3) Wait at least fifteen seconds.
4) Plug the power cord back in, making sure the power button is not being pressed at the time. Then reconnect your keyboard and mouse to the computer.
5) Press the power button to start up your computer.
It does exactly the same thing as the SMC_RST button, simply by removing all power from the system. I would assume the reason for this would be that the SMC settings are stored in RAM, which is erased once the power is removed from the board, hence the minimum 15 secs wait which gives time for the capacitors in the power supply and system to discharge.
So yeah, it does do the trick, or has done for me in the past a few times.

Is my Mac Pro Bluetooth wiring correct?

Hi All,
I know this one's a monster on these discussions but after suffering intermittent bluetooth problems recently and only having about 3m reception I decided to see if I could match my bluetooth and airport wiring to another thread and discovered mine is very different!
wire labelled '1' is connected to the bottom airport card point
wire labelled '2' is hanging free
wire labelled '3' is connected to the top airport card point
wire unlabelled is connected to the bluetooth card
Is this correct?
(system profiler states this is a Mac Pro 3.1)

I had posted my query before doing additional research in the Apple Support Community forums.
The answer lies in the "Bluetooth and Mac Pro problem" thread as I belatedly discovered. Is it possible that even after all this time that Apple still has not acknowledged the problem and posted an explanation/apology?

Windows 8.1 Pro on Mac pro resolution problem

I have created a partition for windows 8.1 pro on my 13' retina display mac pro via boot camp, everything is fine except the resolution, when i open the browser, i could see pixels, the words aren't very sharp, but this isn't my biggest problem, when i open the Solidworks software i'm working on, the icons are too small, or the texts are too big for their boxes. what is happening here? anyone knows what is all about, or how to fix this? changing the resolution of the display didn't solve the problem.

This is how the words look like in the browser page, you could see pixels. The maximum resolution for this machine is 2560*1600

Mac Pro boot problem-Get "I have no name!" error message after possible KP

I think I'm having a kernel panic... and trying to keep from doing so myself
3GHz Mac Pro/4GB RAM, 250GB boot drive and three 400GB drives as a RAID for video captures.
I'm still in the process of getting the machine set up with software.
Demo machine from an Apple Authorized VAR that has been running in his office for several weeks. Had installed Final Cut Studio Monday, allowed Software Update to update the Apple software, including the OS.
Edited quite happily with FCP on a multiclip project... and did other things over the last several days.
Had no problems until a couple of hours ago after adding a number of fonts... which may turn out to be part of the problem... or not.
Rebooted the machine, and after what seemed like a VERRRRRRY long time of gray screen with spinning gear icon, the screen goes black with a cursor in the upper left corner.
About :30 later, text appears: "3Ghz-MacPro:/ I have no name!#" followed maybe ten seconds later by "SIOCPROTOATTACH_IN6: en0 error17" and "SIOCPROTOATTACH_IN6: en1 error17"
Screen clears back to cursor... then "3Ghz-MacPro:/ I have no name!#" reappears... and eventually the cycle starts again.
I would infer that en0 and en1 are the two ethernet ports.
I've popped the install disc in, booted to it (which took a while to do) and used Disk Utility to verify the disk. No problems found. Repaired it anyway.
Verified permissions, which found a couple of issues in the library with some files not essential to booting. Repaired those. Rebooted.
Same cycle as above with "no name."
Ran Apple Hardware test (the quick one) and it found no hardware problems.
Am waiting to see whether the AppleCare TechTool Deluxe will boot. Spinning gear continues as I write this (7-8 minutes??)... now wondering whether it's 10.4.x for Intel Macs as it spins.
After waiting a while... decided to go back to the install disk and see whether I can install 10.4.7 to a handy FireWire drive and boot from that...
then remove (or turn off with FontBook) all the fonts I just installed and see whether it'll boot from the internal.
More later. Am watching e-mail on another machine so feel free to offer suggestions.
Thanks
Ted.
3GHz Mac Pro-1GHz eMac-G3 400MHz Lombard Mac OS X (10.4.8)

I installed 10.4.7 onto the RAID so I could see whether it would boot OK, and to swap font folders out so that only the OS installed ones (from the RAID install) were present on the boot's original install.
Booted from the RAID just fine... and was able to do the font folder swap in the main font and user font folders.
Trying to then boot from the boot disk didn't make a difference. Same kernel panic with the text as described before.
Did an "archive and install" onto the boot disk and it came up fine on the fresh OS.
Updated QT and then the OS to 10.4.8 using Software Update (which I understand from the Apple info site is the "delta" version. Combo is also available, and it updates any 10.4.x version to 10.4.8)
Moved over some items in various library folders from the previous system to make the ProApps happy (only Motion's not working) and will get a project out the door today.
Will ultimately wipe the drive and go from scratch on the OS and Apps again.
Looking forward to half a day of intimacy with my Mac Pro and software disks this weekend.
Thanks.
Would still like to know what happened under the hood to cause the problem in the first place... so I can avoid doing anything I might have done to cause the problem... or to avoid other snafus.
Ted

Mac Pro Boot Problems. Kona 3?

I'm having booting problems with a Mac Pro. It's got a kona 3 card in one of the PCI slots, and we've been tinkering with it to try to get the audio to work right. However, I've been having huge problems whenever I try to restart the computer. After hitting the power button, or telling it to restart the screen goes to black and sometimes I hear a chime. However, the computer does not boot any further. Then, after holding the power button down and restarting the computer, I can sometimes get the computer to boot normally.
I suspect the Kona card is causing some of the problems. I have multiple hard drives on the system, and I have the ability to boot onto two separate drives in 10.5.8. Both drives are having the same problems.
it's a 2x2.8ghz quad-core Intel Xeon with 10gb of ram. The Kona card is in slot 2. Slot 3 has also been tried, but similar problems remained.

removed kona card. uninstalled aja programs. restart problems still persisting.

Mac Pro Boot Problems After 10.6.2 Update

After installing the latest version of snow leopard I am now having boot problems on my mac pro.
Symptoms;
-Screen resolution is incorrect at apple splash screen.
-Takes a lot longer than usual to boot.
-Once booted the blue tooth magic mouse isn't imediately reckonised, takes a while to find that.
-Once the mouse is finally reckonised it can move around but can't click on anything or bring up the dock. Tried a wired mouse, had the same problem.
-The keyboard is also not appearing to do anything, none of the shortcuts or quick keys work..
Had exactly the same problem after 3 restarts but on the 4th after leaving it for a good 20-30minutes it setled down and everything was working okay. However this is a recurring problem as I had the same thing yesterday...
I have a my 10.5.8 system backed up on an external so I am running from that at the moment. Don't want to go back to snowy til these problems are solved.
Any help will be greatly appreciated!
Martin

Try Safe Mode (It will take more time to startup in Safe Mode because it runs a directory check.)

MAC PRO USB Problem - Traced to bad Apple Keyboard Extension Cable

I found a fix to a problem synching to my itunes Library on my early 2008 MAC PRO. The Apple supplied USB extension cable for the keyboard was defective.
The symptoms were hangs in itunes and finder synching to iPods and transferring data to USB hard drives. The iPods and hard drives never lost power and no errors/log entries were made. The transfers simply stalled and would not continue. itunes and finder would hang until the drive or ipod was removed. These devices were installed directly to USB ports on the MAC PRO. No other USB devices were connected except for the aluminum keyboard and mighty mouse; the mouse was connected to the keyboard. The keyboard was connected using the USB extension cable that shipped with the MAC PRO.
Hardware diagnostics were all clear. The keyboard and mouse never had any connection problems. Only itunes syncs and hard drive copies would fail; these would occur at random times. I had an open ticket with Apple to have the logic board replaced as it was diagnosed to be a hardware/USB problem.
Removal or replacement of the extension cable on the keyboard (which was connected to a different USB port and NOT in the USB chain with the ipod and hard drives) permanently fixed the problem. I cancelled the Apple HW replacement.
I have noted several posts with others having problems with USB ports and devices. I wonder if Apple has an unknown problem with bad keyboard extension cables.

I think you may be onto something there. I'm just a few weeks into my second Mac Pro and again it's having the same USB problems which led Apple to give me a replacement machine previously. I went through several weeks of considerable testing with Apple Engineers prior to that - an Apple Care application to collect data from my machine, Apple Developer USB prober and two clean installs. The latest machine initially showed no sign of the problem then it started again - 2 iPods "can not be read or written to" part way through sync, Aperture quitting importing from USB SD card reader, USB drives dismounting etc. So I pulled out the Aluminium keyboard and, lo and behold, the iPods managed to get all the way through synching without errors. I really like the alu keyboard so it's a huge shame that it might be the cause of all my problems so far - and the Mac Pro is otherwise a beautiful computer.
But is this really a hardware problem of the internal USB cards and power management or supply?

Late 2013 Mac Pro graphics problem

I have a late 2013 Mac Pro with dual AMD FirePro D300's. Although this could be coincidence, it appears that after updating to 10.10.2, I find my graphics "freeze" after a random period of time (I updated late last week). I can unfreeze by rebooting, or by unplugging the HDMI cable and plugging it back in again. In the latter case, it takes about 30 seconds for the graphics to re-enable, and they are very sluggish after they do re-enable. I have run the standard Apple diagnostics to no avail. Has anyone else seen anything like this? Any suggestions? Any help would be great! Thank you in advance.

Thanks for this response. With nothing else to go on, I guess I have to assume it is some sort of bug somewhere. In looking at the console log, what I see is causing the display to be slow after I unplug the hdmi cable and plug it back in again is what appear to be UI update disables:
2/4/15 5:33:37.955 PM WindowServer[145]: disable_update_timeout: UI updates were forcibly disabled by application "Google Chrome" for over 1.00 seconds. Server has re-enabled them.
2/4/15 5:33:37.963 PM WindowServer[145]: common_reenable_update: UI updates were finally reenabled by application "Google Chrome" after 1.01 seconds (server forcibly re-enabled them after 1.00 seconds)
This does not happen prior to the GPU crash; which from the console log appears to be what hangs the system in the first place.
Note that it is not just Google Chrome that is doing this, every application I use results in the same message. Forcing the WindowServer to quit doesn't do anything (other than log me out).
I am frustrated by this. Googling these issues shows many many other people have similar problems. Being a long time and loyal Apple customer, I am very disappointed........

Mac Pro Bluetooth

hello, I am going to buy a mac pro tomorrow. I am looking to buy the wireless keyboard and mouse. Does the eight-core mac pro's have bluetooth built in or do you still need something like a usb bluetooth reader?
Thank you

Bluetooth is standard. AirPort is extra (and not user-installable).

How To Install internal Mac Pro Bluetooth?

Could anyone draw me a picture in my head of how to install this bluetooth device before I get it and put it in pretty quick? Users guide is no joy. Can';t be too hard? I'm softwared up and external now. Keyboard connectivity is not what I'd like... maybe on account of the third party external usb/bluetooth.
I've been elbow deep in my lovely old G4.

New Mac Pro USB Problems!

It seems the new Mac Pro cannot recognize certain devices. Such as my Access Virus Ti synthesizer- users cannot get the Mac to recognize the USB connection from the Virus. Please help. I'm losing my mind after 7 hours trying to figure it out and the only indication is that the USB ports on the new mac are possibly incompatible... Please tell me I can still use my $3000 instrument with my new $4500 mac pro which i just bought SPECIFICALLY to use with this VIrus Ti synthesizer!
Link to Virus Ti user forums showing other people with the same problemhttp://www.virus.info/forum/index.php/Thread/5522-MacPro-trashcan-and-TI-Anyone- got-it-working/?postID=28004&highlight=trash%2Bcan#post28004

From what you said it appears that the synthesizer is not compatible. That would be a problem for the synthesizer manufacturer to resolve.

Radeon X1900 and mac pro graphics problems

Hi all,
i've a mac pro with two xeon cpu's (2,66GHz) in it. 2GB main memory and a radeon X1900 graphics card. on this mac i use bootcamp beta 1.4, installed the newest driver for this version from the apple support side. also i have updated the graphics FW to the newest version. so all things are on up to date.
my problem is the following: if I play some very graphics intensiv games like STALKER or BIOSHOCK (yes i use my mac for works and sometimes to play), it seems that the graphics card will be to hot. I get a lot of pixel errors. horiz. lines and after a while windows xp is freezeing. so I must reboot the maschine. also VPU recovery comes up.
I've tried several settings (800x600/1024x768/until maximum). 2-3 minutes the game is running well. after that my fans spin up like a plane, get the errors on the pixel side and the game crashes or windows xp is freezing.
i don't know any solution yet. can anyone help me? have some others the same problem?
many thanks
Andy

Hi There,
I was having the exact same problem playing command and conquer 3 in Win XP. I'd play for about 5 minutes or so with the fans spinning at full speed (sounding like the mac was about to 'takeoff'), and then it would just crash.
I followed the advice here, took the graphics card out, clean the dust out and hey presto, the problem was fixed! My MacPro is about 6 months and i was surprised how much dust had got clogged up in there!
