Can't do it anymore

[thefredelement]

How does the ideal solution for your case looks like, in your opinion?

Well there are a few thing rattling in my brain now but mainly it would go like this:

I tell them there's a problem, I send logs/data, we troubleshoot, they acknowledge they got them, find a problem, inform me of it and say the problem will be fixed in a MacOS update in the near future. For something like a wake display issue, I'm ok with that. It's annoying but I'm a software developer so I get it.

If the Mac had a more serious malfunction and suddenly I wasn't able to do my job, I'd expect something like an advanced replacement, real on site service or same day service at a nearby location. These last thoughts are scaring the crap out of me. I'm dependent on this company for my income, their responses can shut me down.

I have a 2013 Mac Pro hooked up to an LG 31MU97-B. I have D300 cards in mine and am running El Cap because I never upgrade the OS before it gets to .2 (Apple can't bug test their software properly these days). I don't have any problems with wake from sleep and I even see the boot screen. I'm disappointed to hear your problems with Sierra (and also your support issues).

Will be interested to hear how you get on with the USB boot this evening!

The only other thing I'd throw in to the mix, is that LG recommend using the mini-DP cable that comes with the monitor in the box and not any third party options (including Apple cables). If you still have the original cable, if you haven't tried it already (which I suspect you have) give that a whirl. If you still have problems then I'm with you - it's most likely a bug in Sierra and the whole "video card is broken" thing is probably a waste of time.

 

[bcave098]

When I brought up my concerns regarding my data using the company he arranged his only suggestion was to use to wipe the drive. I just can't believe that is the solution they recommend. It's like a rabbit hole of time. He then said I should call around to not only apple stores but to other local authorized repair shops to find one who can just swap the cards. If this is the top of the food chain of apple's support we're all screwed if we have problems.

What else did you want Apple to tell you. It's your data, if you're that concerned, erase the SSD.

It's not just this issue now, what if this Mac is fried and my work just stopped dead in it's tracks? I need a company that has my back.

If your work is considered mission critical then you should always have a contingency plan.

 

[evoluzione]

He is not the top of the support chain, that's complete *****... There is ALWAYS someone more qualified (unless they really have screwed it up way more than when I was there). Even someone in a different department might help, like Carpe Facto, where their sole job is to get to root cause and work with engineers on emergng issues and fixes etc.

I think you really need to spend $100 and join their Joint Venture program. Check it out here:
http://www.apple.com/retail/business/jointventure/terms.html
Of course their site is in need of updates, as always, but basically, you get priority service, and priority repairs. As well as a loaner machine if warranted (not gonna be a Mac Pro though I don't think, but maybe).

Hope that helps with your sanity and concerns about being unable to work etc!

I know you might not consider this as a longer term option, but I was in a similar position. I do software development and was using the 2013 nMP. It got to the point where I couldn't justify the cost of the machine with the issues I was having. I was having issues with one of the GPUs causing random crashes and all sorts of issues, but I need 100% uptime and couldn't take a hit with sending the machine off for weeks. If only I could just swap out the GPU I could keep on moving along.

Therefore, I finally made the switch to a hackintosh. I had been debating it for awhile now and finally found a good build I wanted using the new Broadwell-E. It has M.2, plenty of ram, plenty of internal expansion and Nvidia GPU(I do GPU programming). Most of all the machine is rock solid. I have locked the version at 10.11.6.

If you do software development putting together a solid hackintosh is trivial and once it's setup and as long as you don't do any software updates the machine will be 100% reliable. If a part goes bad you can easily swap it out and keep on working.

I *think* the latest Xcode can work on 10.11, if it works I'll transition the internal SSD and just get on with life at the moment.. I complain about wasting time and am now spending time complaining about wasting time.. :/.

I do have the box and all original cables still. I'm curious that they rec. that though it's a display with thunderbolt.

You're 100% right, I guess I was under the impression that Apple was my contingency plan. I think it's all compounded by my thinking the replacement cards won't do anything except having wasted my time. I need to ensure I can keep working - that's on me.

This isn't a bad idea. I can just have a hack PC here and keep it updated to the latest required tool chains that covers my work. Everything is on git and/or iCloud. The alternative of a pure windows and/or linux install would require some virtual machines for a large chunk of my day. I'm not sure how much I love the idea of that. Or switch to C# and try not to throw up in my mouth everyday , I kid.. kind of.

If I'm still open to giving Apple money the next time I would buy a qualifying device I'm going to go for it. I wish I knew about it earlier.

Your contingency plan for your mission critical work is to rely on consumer support? No wonder it doesn't match your expectations.

Ha! When you put it like that I feel like an idiot. I guess I just thought in my mind, I'd have a problem, bring it to the store, they fix it and I come home and get back to work. I have other Macs I can use to get me through but anything more than a few days and it's annoying. Sometimes I work from my Mac Book at night and it's nice to get away from the desk but man Xcode can really make that thing a slug (it's a 2015 i7 model too). If I have to do any work in Sketch I usually hold off unless I really need to get it done and I'm out and about, that's probably more on Sketch's end, either way the Pro can handle lots of windows from each much better. I haven't toyed with the idea of an iMac in about a year - I wonder if I made the right call going with the Mac Pro.

I really am curious about what they use inside Apple when they work on their own apps/OSes, etc. I wonder what their workflow for problems is as well, do they just call IT and someone comes up with a new Mac?

I can't picture someone working on some app and clicking onto their storyboard file and then watching the beachball for 30 seconds as the thing loads, maybe that's the way it is but I really hope not.

ahh crap yeah, sorry, forgot about the qualifying device crap :/

when I/you/we can't rely on Apple to support their products/customers, it's time to move to alternatives...which these days are very very competitive... I doubt I'll ever go back to Apple, M$ are killing them in design and more. Who even knows how long they will support their Pro/ProSumer base? FCPX appears to be their only concern, and then I'm not so sure how long that'll be around.

in fairness, that IS why a lot of people buy into Apple, as they believe the reliability is better, and that the service options are better - and they certainly USED to be, most definitely not now however.

I *think* the latest Xcode can work on 10.11, if it works I'll transition the internal SSD and just get on with life at the moment.. I complain about wasting time and am now spending time complaining about wasting time.. :/.

I'm a developer too and can confirm that Xcode 8.1 (8B62) runs fine on El Cap. I develop for iOS so don't know how it would cope if you were targeting macOS 10.12, however as the SDKs are there...

 

[ActionableMango]

I've taken my Mac Pro in for service and didn't need to provide any drives at all, so I popped them all out. I would be really shocked if an Apple repair shop didn't have bootable blade/USB/Thunderbolt drives for testing clean images and different operating systems. Eliminating a customer's weird software/settings/drivers/corruption by using a clean image is a basic step for troubleshooting before you start replacing expensive hardware.

Granted, I did ask them ahead of time if that would be okay and they said yes. In fact the first thing they asked when I showed up was if I had any critical data on the computer that hadn't been backed up elsewhere. When I told them there were no drives at all, they were happy to not have the responsibility for my data.

Awesome! That's most of my current workload so going back is an option. This makes me think just to do it and get back to normal already.

I asked the person I spoke with today if I could just take it out and he said something like it's not a user serviceable part so it needs to be there. I didn't get to call any stores yet, hopefully soon or this evening, maybe they will be more able/ willing to work with me.

The person also suggested I find an authorized repair center from apple.com, as they may be more willing to work with me and swap the cards while I wait, the first one came up had this on Yelp, from the owner in reply to a negative review:

This persons is complaining because his logic board became defective as a result of auto updates from Apple OS, which apparently is not compatible with his Mac model.

https://www.yelp.com/biz/american-computer-wantagh-2 (reply on the bottom of the long bad review).

I think if I go this route I'll stick with an Apple Store...

They would be using mbps....don't worry about MPs....because they cease to exist at Cupertino.

The fact that you have to send your machine in for repair, a pro machine you are dependent on is one of the MANY reasons I decided to switch to PC. I understand your problem and its frustrating. Imagine if you don't live in the US. I live in a country were apple has no apple stores and if I need to send in for repair, I have to deliver it to a local store, they ship it to who knows where and I have no clue if the repair will take a few days, weeks or months. I delivered my iMac because of image retention and had to live without the machine for 3-4 weeks. Luckily I was in a transition to buy a new machine, so I lived with the problem and sent it in when I got my new machine and sold it when it was repaired. But, for me this is one of the main reasons I think the apple logic of everything soldered is a bad solution for professional machines. Now, if anything goes bust on my machine I can simply just replace it myself.

But I must say, if Xcode and Sketch is 2 of your primary tools, you are kinda stuck. There is nothing on windows yet like sketch. CC Experience Design will be out just around the corner, but I suspect it wont be as good as sketch. And you don't have Xcode.

 

[JamesPDX]

Not to mention that some of the customers they have to deal with are insatiable and the level one people can't make any exceptions

Over the last 20 years, Apple set up the high expectations of customers for build quality and service. And all at a premium.

In-home service is not "in-home" if someone is taking your machine out the door. It means on-site.

Those Mac Pros should be of at least the same build and component quality of the 2009-2012's.

The good news? You just saved me $3000 on an out-of-date Mac Pro for my studio. Best of luck, and I'm sorry that you're having to deal with this.

Seriously, if he can't use his machine and there's not another at home, then a clipboard and a pencil are the only things that will help until that nMP is back in service. The OP should receive a full brand new replacement for the grief.

 

[AidenShaw]

Not that it's the same case, but I like that my Dell Precision Workstation that I bought for my self at home has four year next business day in home service.

Which I've never needed to use.

This IS the absolute reason the nMP is a POS.. Especially for small shops (like me).

My 2012 (bought new in 2014) cMP is stil covered by Apple Care.

The original boot drive is sitting in one of four bays - I never use it.
The original memory chips and video card are in a box in the closet.

If I ever have some sort of service issue, I will pull out all my working drives and replace original memory and video.
The original drive will be moved back to bay 1.
Off to service it goes while I work on my laptop, which is my mobile dev machine.
[doublepost=1481250142][/doublepost]Well.... I guess you could have done the same thing with the nNP SSD.. But that will be hard in future Mac hardware when all the SSD is soldered in... This IS why the Mac is failing.. We've been saying this for 2+ years now in the hope that Apple will catch a clue.. yet we've been derided by the Flavor Aid drinkers here.

 

[thefredelement]

I'm curious as to whether it worked with El Capitan when you tried it out?

I'm starting today on El Cap, so hopefully everything is good. It's still connected via Thunderbolt - this is a configuration that used to work fine so I want to make sure it still does.

They would be using mbps....don't worry about MPs....because they cease to exist at Cupertino.

Holy cow, that's kind of sad. I don't think I have projects nearly half the size of some of their apps, I wonder how they do it. I've started modularizing a lot of code into frameworks, it helps. But man Xcode chokes my MBP big time.

I keep saying my next project will start with Adobe XD. I like how it'll work with the rest of CC, I'm just very used to and fast with Sketch at the moment. I can't get around Xcode, I could keep this thing headless and remote into it or create a VM.

You have a better plan than I do/did. I did want to replace the SSD with a faster 4 channel version but now I'm unsure if I'm going to keep it or what to do moving forward, I think that's the best I can do at present time.

 

[ProjectManager101]

I've gotten a Mac Pro 2013 around a year ago. I've defended it in these forums, back then and recently when announcements happen with no updates to the product line.

My biggest argument for the Mac Pro was that it can still be supported, as a pro software developer - I need my computer to have warranty, I need it to be rapidly fixed so I can work. I've got other Macs but I need a pro machine for the varying tasks involving interface and software development that I do on a daily basis. I have 5 virtual desktops open and they are all cluttered with Sketch and Xcode windows.

My Mac Pro will sometimes not wake my thunderbolt screen after it sleeps. The only cure is a hard reset. This is new to 10.12.x.

I emailed Tim Cook with a bit of a rant, I didn't realize on a daily basis how many little Apple originated annoyances I deal with. I guess that email got forwarded to some support person who reached out to me to deal with the primary issue of my screen not always waking.

After some logging and back and forth, though concretely reproducible via software (restarting w/out logging in will always cause my screen not to wake after it sleeps), the support person I spoke with said my Mac was made in a certain date range and may have a bad video card. (Though it has 2 D700s)

They proceeded to tell me I can get an in home repair because the Mac has Apple Care on it, or I can bring it in to an Apple Store. I opted for the in home repair and was setup with some 3rd party, who later called me and told me they will pick the Mac up and take it for up to 48 hours and then bring it back. Obviously this is a minor PITA but the more I thought about how I'm not able to protect my data on the disk (can't use fire vault because no boot screens or fire vault unlock due to my MST display), the more I didn't want to do that.

I reached out to the Apple person again who told me that company was the only one available. Now, I'm located in New York, about 30 minutes outside of NYC, I find it really hard to believe that only 1 company can service that entire area and that they are the only choice.

He said they probably want to do that to ensure a static free environment, which aside from leaving the plug connected to alleviate any discharge in a properly grounded system, can be avoided by a strap. Secondly, the RAM is user replaceable and exposes the same things as swapping the video cards will.

Aside from that, I asked if he could set me up with a local store with the smallest repair queue and pre order the parts in hopes of being able to do it while I wait. He couldn't help me out with that, we left it off with that I have to call around and see what store can help me get my $4,000+ Mac w/Apple Care repaired. All of this and I'm 99% sure it's a 10.12.x glitch (that's coincidentally spoken about all over the web - including Apple's own forums).

I think I'm done, it's not that the set of 1st world problems is more than mildly annoying, it's the paying for the premium that doesn't exist. I can't give Apple my money anymore. I can switch everything to other platforms except Xcode, I don't know if I'll really go through with it, I just want it all to work right but I think Apple can go screw themselves with their crappy time wasting service.

You complain too much and is making me sick. Be a man and stop crying. It is just a computer that will be fixed.

I would imagine they have specialised systems for internal use. They could also write the code on machine A, and have it compile on a group of machines - the render farm principle applied to compilation and testing.

I have a mini that runs my tests, I'm not sure how to setup Xcode to compile across multiple machines but that could lead to some type of redundancy solution for me. I'll look into it.

Disclaimer - I've never actually tried doing it, and am unsure if it's possible within Xcode. Though you could use a bash shell with the commands watch and a command line compiler to regularly do compile tasks spread over several computers or something along those lines. The command line is always more flexible.

I might have a similar issue with my lg ultra wide monitor as per this video (towards the end)

My solution is to flick the switch at the back on / off otherwise you have to wait for the grey 'no input' screen then wait for the standby light to flash THEN press the one button to wake it.
