Mac Pro Late 2013 Cubase 8 Problems

Hello
I'm currently running Yosemite on the late 2013 Mac Pro.
I'm having major issues with Cubase 8.
When i select my Virus TI Channel, the whole program crashes. Sometimes it just randomly crashes.
Also, vst2 plugins are really laggy, and i can't figure out the problem, vst3 is fine. happens on 32bit and 64 bit version of cubase.
I tried reinstalling everything (including a clean OSX) but didn't help.
Back on mavericks i also had the VST2 laggy problem, but i had no problems with the virus ti at all.
I can't continue any of my projects now because it's just crashing when selecting the virus ti channel. (It does in empty projects aswel)
I tried different virus ti drivers, but that doesn't help at all. I know people that are using cubase 8 on yosemite with the virus and they have no problems, so i'm pretty sure it's not because of that.
Sometimes when i'm on skype for example, it freezes. when i quit it and try to reopen it the icon just keeps jumping in the dock. This also happened with chrome and twitter a few times, maybe the problems are connected with eachother? i don't know, just giving as much information as i can, because i really want this fixed. Cubase is showing crashlogs after it crashes but i can't figure out what it means.
Today i saw something in the crashlog about my graphicscard (2x AMD FirePro D300) could this mean something?
Anyone that could help me out here please? cause i've no idea what else to do.
Oh btw, i tried studio one aswel, the VST2 Lag problem is also happening in there.
My setup -
Mac Pro Late 2013
OSX Yosemite
12 GB Ram
Quad-Core Intel Xeon E5
2x AMD FirePro D300
Cubase 8

Greets!

I was using a hub, so I immediately removed that upon the first issues.  But the USB has still frozen after the removal of the hub. The HD is a self powered G-Tech drive.  I'll have to play around a bit more will all of your suggestions this weekend.
I woke up the computer just now to check the discussion, an am greeted with a notification from Mavericks that the "Disk Not Ejected Properly. (Eject disk before disconnecting or turning it off)"  which the disk is still connected, and the usb seems to still work fine.  In fact I was able to unplug the USB cable for the G-Tech HD, and then replug it in, everything reappeared fine.  The USB bus was not frozen (this time).
But it's this kind of flakiness that has me coming and going.  I haven't (yet) been able to identify whether the USB is the problem or the driver or a third thing I haven't figured out...

  • Mac Pro Late 2013 USB problems / freezing

    I have a quad-core CPU Mac Pro late 2013 (Model Identifier: MacPro6,1).  MacOS X 10.9.5.
    I have had all sorts of USB devices hooked up to it.  At any one time, I usually have all 4 ports filled.  I have a 3TB USB 3.0 disk that stores my large files, a USB mouse and keyboard (logitech with a usb mini dongle), a cable to charge my logitech USB cordless mouse, Lightning cable to my iPhone 5, and other things that I rotate in and out, like CF card reader, Audio Box USB audio interface from PreSonus, Sony Webcam, etc.
    About 3 months into having the Mac Pro, I noticed that my keyboard went dead in the middle of using it.  The mouse was dead too.  I blamed the RF dongle that they both share, because the Apple Magic Trackpad (bluetooth) I have still functioned.  Try as I might, I couldn't get the keyboard or mouse to work again, so I used the Magic Trackpad to restart the machine, and then my keyboard and mouse worked again.
    It wasn't until later that I realized that all the USB busses on the machine had frozen or "died" temporarily.  I realized it later because my USB hard drive complained about being "ejected improperly."
    Now I have had the USB die on the Mac Pro at least 15 times over the last month and a half.  Usually once every two days or so.
    I have tried (almost one by one) using some of the USB devices on the mac, and removing others to ascertain if it's a certain USB device that is causing this.  But the odd thing is that I never get a message from the OS like "xxx USB device is drawing too much power."
    I'm going a little nuts here because I cannot see any rhyme or reason to the USB interface lock ups.  And each time it happens, all the USB devices go dead until I restart.  Sometimes, I'm able to SSH into the machine from my iPhone and issue a "shutdown -h now" and even though I see the Mac OS X UI shutdown, it never fully halts.  I often have to hold the power button to get the machine to turn off.
    I really can't say if it's software related, hardware related or what.  I've tried to watch my workflow carefully to see if anything seems to make a pattern, but nothing yet.
    Any suggestions? Is anyone else seeing behavior like this?  Do we think it's a USB device... or is my Mac Pro flakey?
    Thanks!

  • Mac Pro (Late 2013), Photoshop CC stamp tools and Yosemite Problems

    Lately when I'm using the the stamp tool in Photoshop CC after a few clicks I hear a short "click click" out of the Mac Pro Late 2013 when then goes on to freeze
    my keyboard and basically makes it useless. I then have to save the photo by clicking in the menu bar, restart the computer which clears the problem. I'm using a Wacom Intuos Pro and thought it could the problem but I tried it also with a normal usb mouth clicking on an image and get the same results. What is this "click click" noise because as soon as I hear that I know that the Mac Pro is going to freeze.........anyone else having any Photoshop problems?

    I've not tried exporting with Premiere but with After Effects on my identical Mac Pro also using istat menus, I rarely if ever see the 2nd GPU spin up. I'm exporting right now for example and:
    makes me wonder if this is infact an issue with Istat menus or if the 2nd gpu really isnt being utilized.

  • Strange Mac Pro (late 2013) Wake Up Problem

    I used chrome browser on my Mac Pro last night and watched some YouTube videos. I stopped the video and put the computer in sleep mode without closing the chrome browser. Today, I tried to wake up the computer and something strange happened.
    The Mac Pro appeared to be on because the YouTube video started to play. However, the sound only came out of its internal speaker and the two monitors were not awake. I could not login at all and had to do a hard shut down by pressing the power button for a few seconds.
    Has anyone had the similar problem also? I contacted Apple Care and they asked me to do the usual SMC and PRAM resets, as well as booting into safe mode and then in normal mode.
    This is the replacement Mac Pro already. The first one had boot problems when two monitors were connected. I took it to an Apple Store and a specialist examined it. He then talked to his team lead and both of them suggested I should return the Mac Pro ASAP. I saw some other user on this Forum had the same problem as well.

    I just wanted to weigh in with my personal experience with Apple over the past 30-odd years. We are a small business and cannot afford a lot of tech support. However, like most businesses these days, you cannot survive for long without technology. We have had PCs and Macs over the years and have become 99.9% Mac run. I do not have issues with reliability with our Macs, which have performed in most cases flawlessly over the course of the last 10 years (prior experience was more problematic - in days prior to OS X and Intel). I have had many many PC issues even with a smaller subset of units. But I do not feel that my experience one way or the other is not demonstrative of either platform on a broad scale. My experience, like yours, is anecdotal at best. I am not doubting your experience with your Macs. I am doubtful that everyone experiences this. 
    So over all, my experience with our current crop  of 30 Macs from laptops to xserves is that they are extremely reliable, with very few, if any, crashes. Which is not to say we don't experience problems from time to time: hard drives fail, power supplies give out, RAM fails, and a myriad of other user-sourced issues all have happened. But the overall experience is that I can get 6-7 years of heavy use from our Macs, and 3-4 from our PCs. Each have their issues. But all technologies fail ultimately. I expect that. I find it equally hard to believe you did not have any issues with 12 years of PCs. But once again, my own experience is anecdotal and not conclusive. Which is why I try to refrain from painting either platform with a broad brush. I am grateful we have choices and that each of us can find what works for us.
    I hope your experience improves and wish you luck in solving your current issues. BTW, I have found Apple Tech Support to be extremely helpful when we do have problems and I avail myself of their expertise freely. I am fortunate to live close to a thriving Apple Store with some really dedicated staff. One last thought, we just purchased a new Mac Pro (late 2013) model as well. It is a dream machine for us: powerful, fast, quiet and easy to configure. We are very happy with it!

  • My Mac Pro late 2013 hangs at 18 minutes left on update to Yosemite.

    I Attempted to update my Mac Pro late 2013 to Yosemite after it was released today through the Apple Store. Unfortunatly after several hours and many auto restarts it hung at 18 minutes to go.
    THe Mac is backed up on an Airport 4, but is there any other way and how do I get to the backup?
    Thanks for any help.

  • Premiere Pro CC crashing on brand new Mac Pro (late 2013)

    Such a big disappointment, yesterday our brand new Mac Pro (Late 2013) with OS X version 10.10.2 was installed and Premiere Pro CC is constantly crashing. One of the problems is that when I open a brand new project and before I add any content to a new sequence I just want to position the video track higher so I can see more audio tracks, the program crashed. I did it several times (new projects, new sequences) every time the same crashing program.
    Deinstalled Premiere Pro and reinstalled it again, but no luck.
    Tomorrow I created a whole new account with administrator rights on the Mac, the issue as described above was gone but at some point in time the program crashed again, and when I reopen the project, with two sequences open (one with footage and one empty) and I want to close the empty one, Premiere is crashing again. So I can't continue my work on this project and need to start over again....
    This is the error report that I'm getting....
    I hope somebody can help me on this because it's very frustrating...
    Thanks in advance

  • Why isn't Photoshop fully optimized for the Mac Pro (Late 2013), and when will this happen?

    On the new Mac Pro (late 2013):
    Currently, Photoshop CC 2014 seems to lag behind iMacs and Macbook Pros (even older ones) for some tasks.
    I assume that this issue is related to either multi-core processing but seems more likely to be a problem with the ATI GPUs not being optimized as the Nvidia GPUs are.
    Why is this the case, and when will this be addressed?
    Any feedback from Adobe official would be appreciated.
    Thanks

    That's what it suggests to you, in the limited scope of your vision and knowledge, and without your having provided detailed specs about your hardware.
    Due to the current unavailability of clairvoyants and mind-readers in the forum, we respectfully request you supply sensible, complete details.
    We don't even know what your specific issues are, and for all we know you may be running the pathetic, buggy Yosemite OS—which Apple is giving away for free.
    In this case, you have been enormously fortunate in that you received a reply from none other than Gµrµ Chris Cox, a top Adobe engineer who has been writing Photoshop code since the last millennium.

  • Cannot connect from Mac Pro late 2013 to Macbook Pro

    Cannot connect from Mac Pro late 2013 to Macbook Pro . I have tried via ethernet and wifi. I can connect from the MBP to the Mac Pro but not vice versa. I have tried to connect to other MBP's on the same network with no luck. I try and connect as a registered user, as I usually do, with no luck. When I enter the Username and then Password the box vibrates as if the details are incorrect, they are not however.
    Thanks in advance
    Jeff

    It is 'just not working' again.
    To answer you question. Other sharing services work. I can connect as a guest. I can share screens. I cannot air drop.
    I cannot connect either way now i.e. from Mac Pro to MBP and vice versa.
    I cannot connect to my wife MBP either. My wife cannot connect to my Mac Pro.
    It neither works with wifi or ethernet cable.
    I can connect to my Time Capsule directly and Time Machine backups are working.
    The passwords are 100% correct.
    The Mac Pro is a late 2013. Does anyone else have a similar problem? I have never suffered this one before. Seriously effecting my workflow
    Thanks

  • Mac Pro (Late 2013) random improper shotdowns

    My Mac Pro (Late 2013) running OS 10.10.3 has been experiencing intermittent shut downs and memory showing as less than installed. At times it shows me the full 64 GB installed, at time less, 2 slots empty, sometimes one.
    Model Name: Mac Pro
    Processor Name: 12-Core Intel Xeon E5
    Processor Speed: 2.7 GHz
    Memory: 64 GB
    My Bluetooth has been also problematic lately. Continued disconnection of both my wireless mouse and keyboard.
    I have gone through diagnostics and found no issues. I did also reset System Management Controller.
    Please help!
    A million thanks in advance!
    Adolph

    I might have seen that one before here.
    Is it always the same location that is not showing?
    If so try interchanging that stick with another one.
    If it follows the stick that indicates a problem with that stick.
    If it remains with the slot that means a hardware problem with the Mac. I would look at the slot with good lighting and magnifying device to look for abnormalities,
    If a hardware problem with the Mac then make an appointment at the Genius Bar of an Apple store.

  • Intermittent HDMI signal on my Mac Pro late 2013

    Brand new Mac Pro. Used for short periods of time for a week with no problems. After these few days, during a little bit longer session of work, I got display problems. Intermittent output signal by HDMI cable with image disappearing from monitor and coming back for some times. Problem occurred both in 720P and 1080i mode. The problem appeared and disappeared for several times. During one of this occasions also some bad green pixel remained stuck on the display.
    Left the Mac on for all the night, this morning I do not notice any problem. Does anyone knows which kind of problem I got??
    It seems to be a graphic card problem isn't it??
    Thanks for help to everyone.
    System: Mac Pro late 2013 - 6-core - 32 Gb ram - 512 Gb HD - FirePro D500 3 GB - Mavericks 10.9.5

    Nothing connected to Thunderbolt ports.
    Do I need to to reset SMC and PRAM anyway??
    The Mac is connected to the Tv/monitor through my Bose LifeStyle.
    Bose LS is setted to 1080i resolution and upscales the signal of the mac when in 720p.
    Already tried at 1080i on 1080i and changed HDMI plug but problem shortly occurred.
    Same device used in tha same way for years with Mini Mac without problems.
    Is it possible there is some conflict between output of the Mac PRO HDMI and Bose LS??

  • Eye strain on Mac Pro late 2013

    Hi guys,
    I Have a problem with my Mac Pro late 2013. After few hours of work my eyes start to hurt really badly, my head hurts also. I am working on Dell U2713HM, few days ago I changed it for a pair of u2312 Dell monitors and I feel the eye strain again. When I try to work on my Asus laptop using the same monitor I don't have a problem. I tryed all the advices on the web for eye strain regarding monitor configuration but it has no effect. Also i can see the image on the monitor isn't rendering properly for example when I open an image there is always some square parts randomly missing.
    Do I have a graphic card problem, monitor problem or something else.
    Any experiences anybod, please help.

    I agree I tried a little Google and came up with this site maybe something to look at https://discussion.evernote.com/topic/47161-mac-evernote-clip-rectangle-control- command-c-not-working/page-2 and there seems more have problems thoug not with Mac Pro MBP Retina: Poor image quality from hdmi output

  • My Mac Pro (Late 2013) with an Apple SSD as the only storage will not restart

    I have a Mac Pro (Late 2013) with an APPLE SSD SM0256F as the only storage.  When I restart all I get is the spinning bars. I have to manually hold the power button down to force shutdown. I have let it try to restart for as long as 30 minutes. It will start just fine from a shutdown.  I am running Yosemite 10.10.2 (14C1510). I have used Disk Utility with no errors. The only time I need to restart is after a system upgrade. I have tried, as others have suggested, selecting the drive from the Startup Drive preferences with no difference. Any help is much appreciated!

  • ATI catalyst drivers not working properly in Mac Pro late 2013

    Hi, I have a 6-core Mac Pro late 2013 with two D500 ATI graphics cards and installed Windows 8.1 Pro through bootcamp. I have installed the bootcamp drivers while in windows installation, however there is a problem opening the Fire Pro drivers (catalyst drivers). I get a message that says something like "there is no option to change so the software will not run". I also tried to download the ATI drivers directly from their site, but still get the same problem.
    This poses a problem for me since I need windows for a specific lighting design software that I work with -Dialux-, and it uses Open GL, which doesn't seem to work in my configuration. Does anyone have any similar problem or solution?
    Please help. Thanks.

    Does the reader show up under USB in System Report?
    If the reader is working properly both the reader and an inserted card will show up.

  • Mac Pro (Late 2013) OSX abnormally slow

    Hi,
    I'm not sure why but my OSX is running much slower then before, weird thing is I don't even install many softwares in it. Below is the description of the issues I'm facing.
    Beach ball frenzy, lots of things ended up with beach balls from switching back and forth between apps (safari and cad). Within app itself, safari freezes occasionally and then whatever I click during that time period (like opening a new tab, links in the page) will suddenly open and this goes on with other apps as well, even finder takes a few seconds to show the content.
    Start up time : 14.2 sec
    Waiting for shut down menu to appear : 15 secs
    Click shut down: forever (monitor goes to sleep after 10 minutes of inactivity, but computer is not turned off)
    Previously, whenever software update requires restart, os will just hang and give a grey screen error, this will cause my computer to be in a boot loop where turning off will show the same error as well. Only way I find out is to open in safe boot, apply update and all goes to normal but it seems the problem is not solved cause now my OS just doesn't work properly. 
    Oddly enough, I got no problem installing Yosemite.
    I don't think it's hardware problem cause right now my windows 8 partition is running much faster then OSX. Oh the irony

  • Mac Pro (late 2013) Philips 288p 4K Monitor Issues

    I have just bought a philips 4k monitor 288p for my Mac pro and I have quite a few issues, does anyone know of a firmware upgrade to the graphics card that will solve these ?
    Issues-
    Crashes on boot up when connect to monitor
    Using monitor is slow i.e. mouse seems to jump a bit, text takes longer to type etc.
    When in 'about this mac' it shows the monitor is running at 7350 x 4500 which is mental
    I have connected via Display port to mini display port and mini display port to dual link Dvi adaptor, both have the same issues.
