Mac Pro keeps logging out since El Capitan

Salut Eric,

Voudrais-tu dire que je me suis fait escroquer? 😁

J'imagine que c'est tout à fait possible, après, sait-on jamais, peut-être que le gars est sincère et qu'il fera son possible, je ne doute d'ailleurs pas qu'il l'ait déjà fait.

Je préfère quand même ça à l'attente sans fin de la résolution de ce même problème qui, sous mavericks, m'occasionnait des kernel panic bien plus problématiques et pour lesquelles je n'ai jamais eu d'aide. La résolution fut de passer à Yosemite... mais perso, Yosemite, j'en veux plus trop.

Donc bon, j'attends le coup de fil du 2 novembre, et puis on verra bien. Quelque part ça me paraît louche qu'ils nous pondent une màj pour un problème isolé comme celui-ci, mais on peut toujours rêver!. Et puis bon, quand tu lâches près de 6000 boules pour ce genre de matos, il reste appréciable que quelqu'un soit à l'écoute, en tous les cas, eux, ils ne lâchent pas l'affaire, du moins pour l'instant, je ne sais plus combien de fois ils m'ont appelé.

Merci pour ton mot, ça me permet de relativiser sur la résolution du problème et la qualité du service mais aussi de conserver une part de scepticisme, ça ne fait jamais trop de mal, moins qu'un optimisme exacerbé et illusoire. 😉

For non-french speakers, I won't translate everything but let's say that hope an good will are the only things we have. Oh, and last detail, I didn't make the Nvidia update as it seems useless.

Hello,

Non, non je ne veux pas du tout dire que tu t'es fait escroquer ! 😁

Simplement que le processus d'assistance et ce que nous font faire des gars d'Apple en Irlande reposent en réalité sur la bonne volonté de leurs "collègues" ingénieurs basés au États-Unis… Ici en France on peut tomber sur un interlocuteur Apple au téléphone qui est d'une volonté sans failles, d'une gentillesse et d'une patience à toute épreuve, en plus d'être compétent ; mais si ces collègues aux EU à qui il doit tout remonter ne se bougent pas, dans la mesure où le cas du client "n'est pas dans le manuel"… et bien ça ne va pas bouger.

Et avec les MacPro pré-2013, on est justement dans ce genre de situation. Donc je crains que malgré toute la bonne volonté de ton interlocuteur, il ne dispose pas des billes pour faire avancer le schmilblick.

Mais en aucun cas je ne pense que ton gars est un escroc ou quoi que ce soit dans le genre ! 😎

Salut,

Je comprends bien, c'est vraiment dommage d'exercer autant de bonne volonté et de se faire rembarrer selon le bon vouloir d'un ingénieur, c'est une "philosophie" un peu contradictoire... et vu qu'un des gars du thread s'est fait dire de downgrader sous yosemite aux US, il y a de fortes chances qu'il m'arrive la même chose. Merci pour l'info en tout cas, ça m'apprendra à changer de système de manière intempestive! Tout ça parce que je voulais que mes Idevices soient à jour avec mon ordi! 😠 Satané système! 👿

Allez, bon dimanche !🙂

I do not believe we've been scammed, but we are the victims of corporate disattention. The company has new products it wants to sell for the investors. Keeping the installed base happy is only a part-time goal. The solution does not lie in any of us users sending bug reports generated with terminal programs. Apple certainly knows it has a problem with EC. It may or may not care to solve it. The new Mac Pros are more limited machines than the older towers, so there is a substantial installed base that cannot move to EC without losing productivity. Apple has one of the highest market values on the blue marble, worth hundreds of billions of dollars. For $700 x 2 dollars, its software engineers can buy two identical used Mac Pro 3.1 and onwards with GT120 video cards from some schmuck on eBay. Those engineers can then put EC on one machine and test it simultaneously with Yose on the other machine. They will get the same results we are getting. They would discover as we already have that it is not a user configuration issue. It is an EC operating issue in how EC handles multiple video cards with multiple monitors. Apparently, there is a data collision at the video interface that causes EC to shut down one card and maybe that tells the machine there is another problem that then causes sleep or re-boot. Apple engineers have the software and hardware maps, we do not. A good hacker could figure the solution to this problem, at least diagnose it, but takes way too much time for us mere mortals. It is up to the corporate gods.

The issue boils down to coding, compiling, and a logic mistake. Apple engineers have the advantage in being able to compare EC code to Yose code line-by-line on the machine, so I would think they can find the issue without too much difficulty. But, they are probably a long way from Wozniak. And the gods know that $1,400 is a lot of money for a multi-billion-dollar, multinational corporation to invest in keeping its consumer base functional on older hardware with its flagship operating system. A bean counter is already complaining. http://gizmodo.com/how-steve-wozniak-wrote-basic-for-the-original-apple-fr-15705 73636

Apparently, the only way to be able to use EC with no log outs is to disable « displays have separate Spaces » in Mission Control in the System Preferences, and to upgrade Nvidia drivers: http://www.nvidia.com/download/driverResults.aspx/92203/en-us

And the best way to be able to keep our old machines and avoid to buy a new one if this is the reason why Apple doesn’t fixes the problem would be to upgrade with a newer graphic card: http://www.macvidcards.com

It seems that our older machines which are upgradable, more easily then the new model, can be much more powerful than these new MP from after 2013. So here is a company that sells new PC flashed cards, which are compatible with our machines. Any way this will be cheaper than buying a black R2D2 clone.

I hope all of us will keep in mind all the issues we had with Apple – and I am not only talking about this last one but about the large number of issues that are happening with OS X products since this f*****g iPhone came out and that Apple puts all its attention on that product at the expense of Mac OS X products – and choose another brand that we can rely on.

The worm is in the apple

Lauter352,

I echo the frustrations with Apple's support for older Mac Pros, but just relation to you post:

I have a 2010 Mac pro 6 core that has a SINGLE NVIDIA 680 (aka upgraded, https://www.evga.com/articles/00730/) video card and even with those settings you mention in Mission Control and the latest NVIDIA drivers my machine still randomly reset 90% of the time within half an hour of usage.

I've not read every post, but it seems most people are using dual video cards. I'm using a single card (dual monitors) and still getting the random reboots of the machine making it unusable. I've reinstalled Yosemite and it's been rock solid since.

Firstly, before I post a comment on jonathanwlang's observations, can I point out that I can't "like" his comment on Safari, on my MacPro, it is not a link. I'm logged in, I'm an Apple developer, and the "like" is not active.

Anyway, I'm starting to think that there are "political" elements to the problems with Nvidia cards, as Apple always seems to have had a closer association with ATI, hence its inclusion in the new MacPros, with the notable absence of Nvidia, not to mention Nvidia having to provide its own Mac drivers, while ATI support remains built-in.

Trouble is in the 3d field, which is one of my specialities, Nvidia has some very strong abilities, not the least is it's CUDA API, and the resultant software which support it... "Metal" seems to be a designed as a bit of a "Cuda killer", which is all well and good, but "worker bees" like artists like me live in the here and now.

And I believe that we need competition in the vendor marketplace for us to achieve the fastest evolution of tools, so if Apple is trying kill Cuda, not cool Apple!

Yes I installed the NVS 510 card has 4 Mini DisplayPort 1.2, Using:

Philips FTV 48" TV mini dp to hdmi cable

Acer H236HL Apple MiniDP to DVI Adapter X 2

VGA DisplaySamsung 24" Apple MiniDP to VGA Adapter, but orders 2nd mini dp to hdmi cable.

Had same issue My mac:

Mac Pro 4.1 2 x 2.93 GHz Quad-Core Intel Xeon

32 GB 1066 MHz DDR3 ECC

2 x Nvidia GeForce GT 120 video cards

4 Displays

switched to:

1 x Nvidia GeForce GT 120 video card

1 x Apple ATI Radeon HD5770

Still would crash to login

Installed: did not due anything else no change on the separate spaces or anywhere.

Non Apple NVIDIA NVS 510 2048 MB

Fix that worked for know no more logos, reboots or errors of any kind: No boot screen

Guys, you can actually all relax - this is not dual-monitor only, or so it seems.

I have the same problem with a Macbook Air 13 (2012), no extra monitors.

Getting logged out every few hours after upgrade. 😟

Here is the problem:

Since upgrading to OSX El Capitan the screen constantly goes black and returns to the login window as soon as I attempt clicking on something with the mouse.

Here is my setup:

Mac Pro: (Early 2009)

Processor: 2 x 2.26 GHz Quad-Core Intel Xeon

Memory: 20 GB 1066 MHz DDR3 ECC

Graphics: ATI Radeon HD 4870 512 MB graphics / NVIDIA GeForce GT 120 512 MB graphics

Drives: 4 Western Digital 2TB

Displays: 2 Apple LED Cinema Displays 24-inch (1920 x 1200)

Yes, that is the problem being discussed in the discussion.

I suspect you have one monitor on each card.

Yes, each monitor is connected to a different card. My main monitor is on the ATI and the 2nd is on the Nvidia

Just adding my setup and experience into this. I have a 2009 Mac Pro with 2 NVidia GeForce GT120 video cards and 3 Dell 24 inch monitors. I experienced the EXACT same issue that many have in this thread. That being that when I have all 3 displays connected I get logged off anytime I run Outlook 2016, Word, Windows Remote Desktop, or Firefox for any duration (could be for a very short period as well with any of the aforementioned apps)

I followed the lead by turning off the individual spaces for the displays, no change.

I updated OSX to 10.11.1, no change.

I updated my NVidia driver to the latest one that works with 10.11.1 (That version is 346.03.03f01), no change

I unplugged the last display from the bottom video card, leaving the two plugged into the top video card. I did not remove the second card at all only the display. FIXED

Obviously this isn't a fix, so I am planning on experimenting with various configurations to see if there is a sweet spot that is stable for the time being. I am thinking outside the box, perhaps purchasing an additional mini DP to DVI adapter to see if it provides any better results. I will report back with any results.

I encountered the same issue. Mac Pro, 2 Nvidia GeForce 120s, 3 monitors, 4 hard drives.

I was on the phone with Apple Support and referenced this thread and got it on the books speaking to a engineer one-level up from the call centre guy. They provided me with a direct line contact to send feedback, however I mentioned this thread was still the best place.

During the call, I made note of the recent update from Nvidia. I installed it, restarted and proceeded to try and trigger the bug. After starting 20+ apps, it's still running.

It "feels" solved, but if anyone has a way to force the restart, at this point I want to make it happen to test if it's still an issue.
