2012 Mac Pro - balancing cores

Hi,
I've been reading up on balancing the core usage in Logic 9 (I have X but won't switch until it's a little more glitch-free) but am running into problems where plugins on busses (or Auxes) drive one core into the red rather than spreading across all 12/24 cores.
After reading what Apple stated on their page about balancing multi-threaded cores, I still don't seem to have solved the problem! I've done as they've advised (moving 6-8 plugins from 1 Bus or Aux across 2 or 3 daisy chaining them together) but it still just assigns one core to those buses/auxes.
Am I missing something really obvious here? It's gotten to the stage now where just two UAD plugins are bringing a 2012 Mac Pro (Dual 2.6Ghz 6-core, 24GB RAM, 512GB Mac SSD, 3TB Audio) to it's knees, either on 1 aux, or as shown, across two. There's one other channel (a parallel drum bus) which has around 5 Native plugins on which are being loaded onto the 3rd core (with the 4th core blowing over those two UAD plugins)
How are people generally sharing the plugin load across cores, as it's getting to the point now of me wondering whether a new 2013 Mac Pro is going to solve the issue, which I'd be gutted about as this Mac is normally such a work horse!

Hi Eriksimon, thanks for your reply!
I have my Threads set to Automatic, however I had it set to 16 and it made no difference. Sadly LPX is way too buggy and glitch-tastic for me to move over (one example of the repeat regions feature which has *always* worked since version 5 now slowly copies regions out of time... ) even though it's inviting to think that it'll use all the power I have!
I wasn't aware of the refresh thing upon reopening sessions, but I was working on something today I'd DC'd three weeks ago and again, it fell over, each time at the same place. It's so frustrating!
Buffer size is 1024 samples, PBR is set to Large
Thanks again!

Slow Performance On Mac Pro 12-Core

Hello Everyone,
I just recently purchased a 2012 Mac pro 12-Core and i have been getting unbelievabley slow performance with it. I am using Premiere Pro CS6 and it seems that the footage can sometimes get a bit laggy at times and not play back smoothly, sometimes rendering can take a bit of time as well. However here are the specs of my system:
Mac Pro 12-Core 2.4GHz (2.67GHz Turbo Boost)
40GB of Ram
ATI 5770 Graphics Card
1TB scratch disk (with a user on the drive that i can boot into)
OCZ 120GB Vertex 3 SSD OS/APPS drive
First question i would like to get answered once and for all.. Did i make a bad decision by purchasing a computer with such a slow clock speed (2.4GHz)?? I figured since The new editing software is switching to 64bit it shouldn't depend on clock speed anymore? (i just want to be sure that i purchased a more than capable machine) However i will be buying a Samsung 840 Pro Series 256GB SSD Drive for Scratch within the month. (I dont have the budget to buy a Raid controller yet to utilize 6GB/s transfer speeds, so 1 Fast SSD drive will have to do for now)
I should mention the current SSD drive im on right now only has 13GB remaining, would that affect performance? Also, my 1Tb media drive is filled up with CRAP from my previous computer (Migration transferred EVERYTHING to that drive, only 120GB remains) would that drive with the media im working with affect performance too? Also just as a test, i took some footage from my GoPro Hero 3 camera and put it on my SSD to see if that would eliminate the lag, but still lag was present in Premiere.. (the footage was in a crappy .M4P format, so that may have affected it, but I dont know)
Any suggestions are greatly appreciated!
-Thanks in Advance!

Wrong, clock speed is everything.
I should mention the current SSD drive im on right now only has 13GB remaining, would that affect performance?
No, not really.
Also, my 1Tb media drive is filled up with CRAP from my previous computer (Migration transferred EVERYTHING to that drive, only 120GB remains) would that drive with the media im working with affect performance too?
When fill rates go up, performance goes down. With almost 90% fill rate, the disk performs only at around 50% of a new disk.
Two disks is absolute bare minimum, and your cores will constantly be waiting for the disks to read or write data, sitting idle most of the time.
Also just as a test, i took some footage from my GoPro Hero 3 camera and put it on my SSD to see if that would eliminate the lag, but still lag was present in Premiere..
GoPro material requires a very fast computer, which yours is not with the low clock speed, outdated E5620 CPU's, only two disks, and a non-CUDA capable video card.
Take a look at the PPBM5 Benchmark and look at the system at rank # 854, which is a MacPro, very similar to your system, dual E5620, AMD video card, less memory but uses three disks.
So, your system would be around the same rank as the one above, among the slowest 25% of all systems and something like 10 - 15 times slower than a fast system. You tax your system to the extreme with the GoPro Hero3 material, and the consequence is the slow performance you see.
Sorry, not much you can do, other than get a new system. If you sell it now, it may get you a price, good enough to get a much faster Windows system and maybe even keep the change. Simply said, you bought a MacPro for € 3.5 K, sell it for € 3 K, buy a PC for € 2.5 K that is around 5-6 times faster and your loss is recovered.
However i will be buying a Samsung 840 Pro Series 256GB SSD Drive for Scratch within the month
What a pity the MacPro does not have SATA 6G ports, only SATA 3G, because then that SSD will run at almost half speed.

Thunderbolt update V1.2 is not supported on my system: Mac Pro 12 Cores (mid 2012) with Mac OSX 10.8.3

I'm trying to connect an external 8 Tera thunderbolt hard drive to my Mac Pro 12 Cores (mid 2012) with Mac OSX 10.8.3, and it is not recognizad, so I tried to make the thunderbolt upgrade V1.2, and a windows appears and says: "this software is not supported on my system"
Please tell me waht to do.
thanks a lot.

Erratic wakeup from sleep after 10.9.2 - 2012 Mac Pro

I completed the most recent OS X upgrade yesterday on my 2012 Mac Pro and now "wake from sleep" seems to work erratically (much more often not waking up and requiring a reboot). Occasionally a quick push of the front panel power button will produce results. Nothing else has been changed on the computer so I can only believe that this upgrade has been the cause.
Anyone else having this problem? Suggestions or things to reset/check?

FCS 2 -- Mac Pro 4-core or 8-core?

Been reading both the FCP forum and the MacPro forum and still not unsure which way to go.
I'm an avid Avid user (sorry about that) for many years and now making the switch to FCS2. My confusion lies in which configuration to get to best maximize FCS2-- Mac Pro 4-core with maximum RAM or Mac Pro 8-core with 6 or 8 GB RAM? The machine will be used 90% for FCS 2 so that's the main decision-making factor here.
Been reading articles about bottlenecks that make having 8-cores benign, but I find them hard to believe. Either way, the cost is about the same (the $$ saved buying the 4-core would be spent on more RAM).
Thanks for your time and advice.

With FCS the trick to maximising your performance is balance. Getting the balance right between processor performance, GPU performance, RAM and drive performance can often be a tricky thing. Unless you consider your system as a whole, any improvement in one area will often have little value.
At the price of the 8-core upgrade (more than 50% of a whole new one!) I would think you'd get far better value by going with a 3GHz 4-core system and maxing out everything else.

UPGRADING AND MIXING MEMORY ON MY MAC PRO QUAD CORE DUAL 2.8 (Xeon)?

Hello,
I have a Mac Pro Quad Core Dual 2.8GHz (Xeons) with 4GB of memory (2 x 1GB Apple modules + 2 x 1GB other brand - Shown as "Manufacturer 0x855D") and now I want to fill the other 4 memory slots by adding an additional 16GB (4 x 4GB modules) for a total of 20GB of RAM.
My 2 questions are:
1.- In which order/pattern should I install these new 4 X 4GB modules along with my original Apple 2 x 1GB modules and the "Manufacturer 0x855D" 2 x 1GB modules the best way (for better performance)? - I have heard stories that if I do it improperly, I could slow down my Mac Pro...
This is how I have them configured right now:
Raiser A / DIMM 1 = 1GB (Manufaturer "0x830B") - I assume this is the Apple memory, right?
Raiser A / DIMM 2 = 1GB (Manufaturer "0x830B")
Raiser A / DIMM 3 = Empty
Raiser A / DIMM 4 = Empty
Raiser B / DIMM 1 = 1GB (Manufacturer "0x855D") - How can I find which manufacturer is this?
Raiser B / DIMM 2 = 1GB (Manufacturer "0x855D")
Raiser B / DIMM 3 = Empty
Raiser B / DIMM 4 = Empty
2.- What brand would be most compatible to work with my Apple 2GB (2 x 1GB) factory memory? Kingston? Crucial? Mushkin? iRam? Corsair? OWC? (Does OWC sell their own brand? or which one do they carry?-its not specified on their web)
Thank you so much in advance for all your help!

How can I hook up 3 screens to a Mac Pro 8 core 2010 model?

How can I hook up 3 screens to a Mac Pro 8 core. One is a 23' Apple Cinema Display, the second is a 20" Apple cinema display and the 3rd is a 32' Sony Bravia HDTV (connected to mini port with mini/HDMI connector) Do I need to buy another video card? I have heard about 4 different scenarios about this, and they all sound a bit complicated. I thought that you could automatically connect 3 displays with the card that comes with the MacPro. It has a DVI port and 2 mini ports, so it appears that would be for 3 displays. But this is where it gets strange. Any thoughts?

Which video card? 5x70? If you read about the various scenarios thern for 5x70's you need two active adapters for thee monitors (TV considered a monitor). And you should have seen references to these apple docs:
Mac Pro (Mid 2010), Mac Pro (Early 2009): Issues with three displays and multiple DVI, HDMI connections
Mac Pro (Early 2009), Mac Pro (Mid 2010): Supported display configurations
It's not really complicated. Search out the appropriate adapters and hook 'em up. For the 23" and 20", if they are DVI, you need single link adapters. For the TV, if you end up using the DVI port for it (because possibly you can't find the appropate adapter cmbination) then you need to handle the audio separately since DVI doesn't carry audio.

Welcome to Apple Discussions!
Do you keep your data backed up?
If not, you should always do so*:
http://www.macmaps.com/backup.html
You never know when a hard drive or a directory might go bad. Having a bootable clone is a must.
That link also shows you some tools you can use to recover data.
If you aren't backed up, try buying those tools first, before attempting to repair the directory.
Directory issues can be fixed with these tools*:

Error message on my Mac Pro Quad Core Dual

Hello..I'm hoping someone out there can help or advise me.
I turned on my mac this morning to find it's normal loading screen of grey with the darker grey logo in centre..all normal at this stage. This was followed by a wipe from top to bottom making the background grey a little darker and in the centre the apple logo was replaced by what appeared to be a semi transparent power button symbol with the words. "You need to restart your computer. Hold down the Power button for several seconds or press the restart button"
I have tried this several times to no avail I have also zapped the P RAM again nothing. Can anyone out there help. I have a Mac Pro Quad Core Dual which is only a few months old and is up to date with its system software.
I could be so grateful of any assistance.
Warm regards
Sophia

Make an appointment. But in the meantime...
So from cold boot, you can't do the Command Option P R through 2-3 full reboot cycles (don't let up)?
Unplug everything and let it sit overnight without power cord or anything. That is the only way to rest the SMC system management controller on the 2008 model, the older model still had a reset button.
Also learned that the 2008 Macs can all boot AHT if the original OEM installer was used to install the system and the drive has not be completely reformatted and retail OS X used, just holding down "D" on startup. But you have to
Also, pull all your hard drives. Rule out that, which I have seen a hard drive cause panic on startup, which required disabling journaling and other repairs from Disk Utility and deleting caches, then repair, and finally do Safe Boot (shift key down on startup).
The only way to test RAM is with TechTool Deluxe or Pro; with Memtest or Rember; and to test some devices is to try using a differnent one, keyboard and mouse included if you have any.
Last hope: open case, look inside, take the two RAM Riser cards and pull out, check the DIMMs are fully seated.
If you have 3rd party memory, remove that (would need to before taking in probably).
Might want to put RAM back to way it shipped with 2 x 1GB and one DIMM on each Riser in slot one. Maybe that will wake this sleeping giant. Changing RAM config use to be one way to clear nvram in the distant past in the time of Arthur.
PS: it is "odd" to find a BTO 3.2GHz system, and only 2GB. For memory performance, Barefeats found a marked improvement with 8 DIMMs, and of course Mac Pro really needs memory to feed 8 cores and pro apps (2GB would be okay for web and email type use only).

Windows – but Which? (What to install on Mac Pro Quad Core?)

First, apologies in advance if this seems like repetition of a recent topic, but I read through the recent "Vista vs XP" thread and it didn't quite answer my questions.
Basically, I'm planning on buying a Mac Pro "Quad Core" 2.8 and installing Boot Camp and a Windows OS startup. This puts me into the notoriously tricky area of picking the right version of Windows for my needs, something I haven't really had to deal with in regards to OS X.
Basically, I'm not looking for something with too many bells and whistles or to much bloatware built into the OS. Also, I'll probably be using some older software/shareware, so backwards compatibility is an issue. On the other hand, I'd like something that works with the Quad Core architecture at its greatest efficiency.
This means I'm wondering about a couple of features that I may or may not need, and it would be of great help if you folks could point me in the right direction regarding these:
x64 – Since the Xeon processors in the Mac Pro are 64-bit processors, am I better off with "x64"-compatible versions of Windows (either Windows Vista or x64 versions of XP)? Will this cause problems starting up older programs that may not have been written for x64?
*Dual Processor Support* – the Quad Core, of course, is a dual processor – will I get better performance from a version of Windows that list "Dual Processor Support" among its features (basically, the "pro", "business", or "ultimate" versions of XP and Vista)?
If I need those features, I'm probably looking at getting either the x64 version of Windows XP Pro or the Business or Ultimate versions of Vista. However, I'm leaning against Vista based on backwards-compatibility and bloatware issues. That leaves XP Pro x64, but I might go for a more basic version of XP if I find out the x64 or DPS features aren't actually something I need. (The other "extras" in XP Pro don't sound like anything I need.)
Also, I'm likely to install Parallel Desktop at some point and don't want a version of Windows that would have compatibility problems there, either.
Anyway, any answers you folks can provide for me in this regard would be very helpful.
Thanks in advance,
Peter

Truth is, I am disappointed in VMware Fusions slow walk toward full support for 64-bit and SP1 but 2.0 beta is getting there. Never used Parallels but best to check their own support forums. They also updated the 1.x version recently.

You don't need anything first, except I would start with a new hard drive for Vista, don't even do anything with it and pull OS X drive, boot Vista DVD and go from there, just as you would normally. Much easier. After it is installed is when you need Apple BootCamp from your Leopard OEM DVD, install, and then Apple Software Update will take care of 2.1. And install your graphic drivers yourself.
The problem(s) come with trying to use BootCamp Assist and setting up partitioning, and it only makes it harder - not easier - on Mac Pro (you aren't and don't want to use your OS X boot drive).
Windows on Mac forum @ MacRumors
http://forums.macrumors.com/forumdisplay.php?f=86
And their Mac Pro area http://forums.macrumors.com which has a lot of Vista talk from Mac Pro owners.
The only real issues are which graphics card to get today or in next weeks, what drives you are going with and other upgrades like memory (8 x 1GB is actually a good base ideal figure so all DIMM slots are taken up).

- until the WD "Black" series (I guess Blackbird name or SR71 are already taken) along with 3rd generation of their RE series drives. WD has been popular, reliable, with Mac Pro for last two years. Can't say the same of every vendor. Samsung F1 is also a real winner.

Time Machine should be enough to make a backup of your files. Also, it should back up all folders, so open System Preferences > Time Machine > Options, and make sure that there are no folders included in the excluded items list.

Mac Pro 8 core with boot drive cloned from MacBook Pro

I bought a Mac Pro 8 core and in order to avoid having to reinstall all my stuff, I cloned my OSx (tiger 10.49) partition from my MacBook Pro running vista (installed via bootcamp) to my new MacPro's startup disk. The disk works fine except that the MacPro will not boot to osx unless I use the option key and choose the OSX partition. If i just turn the machine on it doesen't find anything. I think it is looking for windows. What do you think?????
Also, if i restart from the os x partition on my mac pro it stops just before the lound bong sound and seems to be looking for the dvd drive. Any ideas??

Well, I've covered this extensively here:
A Basic Guide for Migrating to Intel-Macs
If you are migrating a PowerPC system (G3, G4, or G5) to an Intel-Mac be careful what you migrate. Keep in mind that some items that may get transferred will not work on Intel machines and may end up causing your computer's operating system to malfunction.
Rosetta supports "software that runs on the PowerPC G3 or G4 processor that are built for Mac OS X". This excludes the items that are not universal binaries or simply will not work in Rosetta:
Classic Environment, and subsequently any Mac OS 9 or earlier applications
Screensavers written for the PowerPC
System Preference add-ons
All Unsanity Haxies
Browser and other plug-ins
Contextual Menu Items
Applications which specifically require the PowerPC G5
Kernel extensions
Java applications with JNI (PowerPC) libraries
See also What Can Be Translated by Rosetta.
In addition to the above you could also have problems with migrated cache files and/or cache files containing code that is incompatible.
If you migrate a user folder that contains any of these items, you may find that your Intel-Mac is malfunctioning. It would be wise to take care when migrating your systems from a PowerPC platform to an Intel-Mac platform to assure that you do not migrate these incompatible items.
If you have problems with applications not working, then completely uninstall said application and reinstall it from scratch. Take great care with Java applications and Java-based Peer-to-Peer applications. Many Java apps will not work on Intel-Macs as they are currently compiled. As of this time Limewire, Cabos, and Acquisition are available as universal binaries. Do not install browser plug-ins such as Flash or Shockwave from downloaded installers unless they are universal binaries. The version of OS X installed on your Intel-Mac comes with special compatible versions of Flash and Shockwave plug-ins for use with your browser.
The same problem will exist for any hardware drivers such as mouse software unless the drivers have been compiled as universal binaries. For third-party mice the current choices are USB Overdrive or SteerMouse. Contact the developer or manufacturer of your third-party mouse software to find out when a universal binary version will be available.
Also be careful with some backup utilities and third-party disk repair utilities. Disk Warrior (does not work), TechTool Pro (pre-4.5.1 versions do not work), SuperDuper (newest release works), and Drive Genius (untested) may not work properly on Intel-Macs. The same caution may apply to the many "maintenance" utilities that have not yet been converted to universal binaries.
Before migrating or installing software on your Intel-Mac check MacFixit's Rosetta Compatibility Index.

Transferring data with Setup Assistant - Migration Assistant FAQ
Because Migration Assistant isn't the ideal way to migrate from PowerPC to Intel Macs, using Target Disk Mode or copying the critical contents to CD and DVD or an external hard drive will work better when moving from PowerPC to Intel Macs.
Basically the instructions you should follow are:
1. Backup your data first. This is vitally important in case you make a mistake or there's some other problem.
2. Connect a Firewire cable between your old Mac and your new Intel Mac.
3. Startup your old Mac in Target Disk Mode.
4. Startup your new Mac for the first time, go through the setup and registration screens, but do NOT migrate data over. Get to your desktop on the new Mac without migrating any new data over.
4. Copy the following items from your old Mac to the new Mac:
In your /Home/ folder: Documents, Movies, Music, Pictures, and Sites folders.
In your /Home/Library/ folder:
/Home/Library/Application Support/AddressBook (copy the whole folder)
/Home/Library/Application Support/iCal (copy the whole folder)
Also in /Home/Library/Application Support (copy whatever else you need including folders for any third-party applications)
/Home/Library/Keychains (copy the whole folder)
/Home/Library/Mail (copy the whole folder)
/Home/Library/Preferences/com.apple.mail.plist (* This is a very important file which contains all email account settings and general mail preferences.)
/Home/Library/Preferences/ copy any preferences needed for third-party applications
/Home /Library/iTunes (copy the whole folder)
/Home /Library/Safari (copy the whole folder)
If you want cookies:
/Home/Library/Cookies/Cookies.plist
/Home/Library/Application Support/WebFoundation/HTTPCookies.plist
For Entourage users:
Entourage is in /Home/Documents/Microsoft User Data
Also in /Home/Library/Preferences/Microsoft
Credit goes to another forum user for this information.
If you need to transfer data for other applications please ask the vendor or ask in the Discussions where specific applications store their data.
5. Once you have transferred what you need restart the new Mac and test to make sure the contents are there for each of the applications.
Written by Kappy with additional contributions from a brody.
Not knowing what you did when you migrated from your PB to the MBP, I can't really comment, but it's quite possible it didn't go as well as you think. Numerous users who migrated from PPC Macs to Intel Macs ended up with an Intel Mac that didn't work properly because Intel coded components had been replaced by PPC coded components.
