Dear Chaps,

I would be most grateful if you could advise me as to whether my much-loved 2.93 Ghz Quad-Core early 2009 Mac Pro is about to shuffle off it's mortal electrical coil. In recent weeks strange things have been happening. Firstly amusing screen glitches - from the occasional flurry of horizontal lines to the pleasantly surreal melting of a patch of text (all in random places I hasten to add). I was hoping that this might be the death throes of my aged Apple fitted ATI Radeon HD 4870 512MB graphics card (ie something I could easily replace) but then other things started to occur.

Firstly open screens would freeze and prove unable to close and this wasn't necessarily because too much was open - this again could be random. However once this occurred even 'force quit' would prove useless and things could only be remedied by the pressing and holding of the start button to shut down the entire Mac. Occasionally this freeze would be accompanied by the speeding up of the fans into hovercraft mode. This cannot be good!

To begin with this might happen once a day but now it happens a few times throughout a day's use. However once it happens you might find yourself restarting into a few hours of undisturbed usage. More unnerving is the rarer recent occurrence (in the past week) of the Mac deciding to restart itself...sometimes successfully, sometimes into a white screen or more entertainingly into a futile cycle of useless restarts. The last time a collapse happened I forced a relaunch and got a report to Apple dialogue box featuring a ***Panic Report*** which I have a copy of should anyone know how to decipher it.

Now I'm not against buying a new 27" iMac, although it must be said that my wife and my bank manager might be. I also note with sorrow that I would lose all the joy of opening up and cleaning the thing myself and being able to add hard drives and PCI cards etc to my hearts content. And therein lies another problem. Back in 2014 I bought a 960GB Mercury Accelsior E2 card which helped my old 2009 Mac Pro no end. It was not cheap. But I now see that this will not slot into any of the new iMacs and I assume that this will be much the same for the 12GB of RAM I eventually added? So will it be worth me buying a new iMac and - for example - a Sonnet expansion chassis to avoid losing the PCI card? I assume yes?

So that's it chaps. Is it dying or simply pining for a new graphics card? Are other troubles always going to be looming on the horizon and therefore do I risk throwing away money by not moving on? Thanks! Nick

There are usually clues in the panic log if it is a hardware problem. The GPU would be most likely guess given the screen glitches you mentioned - if the AMD drivers crash completely then the machine will lock up and panic, the fans speeding up is typical as when the driver crashes the computer will always assume the worst.

If you do go the iMac route you will probably be best of selling on the upgrades as parts to be honest and getting more iMac suitable replacements for your needs.
 
Thanks Matt. Any clearer?

If you post the first part of the log before it starts listing all your hardware and installed software that should be enough usually.

I'm assuming you haven't recently added any new hardware or updated drivers for any? Also to eliminate software you are best removing your disks are booting from another drive with a fresh basic operating system. At least then if the symptoms persist you know it is hardware.
 
I've duly trimmed down the panic report as suggested! No new hardware or indeed updated drivers. Perhaps I could add to my question?

I take your point about selling the RAM but the cost of buying - lets say - the Sonnet Echo Express is £349 here in the UK whereas the price of adding 1TB of flash storage to an ordered 27" iMac is £480. As the external expansion chassis would still have room for another PCI card in the future, wouldn't this be a better bet for future proofing?

That panic log unfortunately doesn't appear to mention the AMD drivers as launchd is part of OS X and the process that spawns everything else.

I would therefore certainly try and use another disk with a fresh OS X install as a first test (with you normal hard disks and SSD/flash all removed to eliminate them and save any further logs.

With regards the flash storage it all really depends what software you are running, of course in an ideal world flash would be dirt cheap and we would all just store everything on it. However as long as the things that need fast disk access are stored there you can actually easily afford to keep other files elsewhere.

The price to upgrade the internal flash storage on an iMac is crazy really and in reality even 1TB could get out grown quite during ownership. If it was me I would compromise a little on the very fast flash internally to keep funds for other options.

Although it's not easy to do the internal flash can technically be replaced and upgrade later as these become more affordable. You can then get more affordable external SSD drives and or mechanical disks as needed. These improve with each generation so you might be surprised how close to your drive these could be.

Speaking personally I'd be reluctant to look too much at Thunderbolt based solutions at the moment unless your specific needs require it and try and stick to USB 3, especially options where you can remove the drives and or use adaptors later as needed. Simply because although it has been fitted on Macs for a few generations now it hasn't really become totally mainstream yet so there is a large premium for what could unfortunately end up being another dead end like FireWire if the PC market don't take to it.

Hopefully Thunderbolt 3 may change this but it is another case of great versus good enough in a technology situation (e.g USB 2 versus FireWire 400, VHS versus Betamax - if you are old enough to remember that...)

Old enough? I remember having only two channels on our black and white television and being collected from school to see 'Yellow Submarine' at the cinema!

To add further confusion, should everything go pear-shaped (and I do by the way have online and external back-ups) is it going to be easier to transfer my old data into a shiny new iMac running El Capitan, if I've already shifted into the latest operating system with this old Mac Pro? I've been cautious up to this point as I believe some people have suffered (ahem) 'problems'....
 
Ha OK! It's not always easy to guess age on forums :)

From the build number it looks like you are on 10.10.5 Yosemite and compared to that El Capitan is like a more polished version so there aren't many pitfall to be honest - you should be able to migrate from your latest backups easily enough. You can easily check into your main applications and see if any patches were released, personally I had far, far less than with earlier OS X version upgrades.

Most of the biggest issues will have been solved anyway with the couple of point releases already done. The biggest change is SIP which is only likely in issue if you have old hardware drivers for devices that are no longer being supplied with driver updates.
 
Not necessarily. Migration Assistant usually takes care of moving stuff between OS X versions pretty well. We moved an older 20" iMac that was on 10.8 ML to a new 27" 5K iMac on 10.11 El Cap and everything copied over with no trouble. Even some older Pro apps, though they needed to be reactivated, they did not need to be reinstalled.

One last thing to check if it isn't the GPU it could also be something as simple as bad RAM. I've had bad RAM in various PCs and Macs cause crazy graphical defects and rebooting. I'd give AHT a run if you haven't already. AHT will also test the GPU and the logic board as best as it can.

Thanks for the additional advice. I'm more than happy to admit that I've just had to look AHT up! Stand by for the pulling of leads and running of the test. Pray for me...
 
Set up screen sharing with another Mac and then yank the 4870 and reboot.

If it crashes while running that way it is GPU.

Did you ever clean out the fan on 4870? They are not maintenance free and will eventually get full of debris. If I posted pic of some of the cards we get used you would lose your lunch. Recently had a pair show up full of cat hair and smoking residue. Yucky

[doublepost=1452377411][/doublepost]I do clean it out pretty regularly but it might have been three months or so since the last bash so perhaps I ought to check; particularly as garden recycling is carried past it's home. For some reason I can't get the AHT to run. In spite of holding down 'D' when starting it just opens up as normal...although for some reason the brightness control also appeared on screen! As I am wallowing somewhat I did find a old copy of Tech Tool Pro. Sadly too old to run on this machine BUT I can buy the upgrade at a discounted $39.99. I don't mind shelling out for this if it's going to help. Would it do the job?

By the way Matt, as far as future iMac technical upgrades are concerned, anything trickier than the current easy pop out and replace system afforded by my old Mac Pro is a definite no-no!

Ah yes, Apple Hardware Test will require your original OS X install DVD. It's usually on disc 2, at least it is on my 2007 iMac and '08 MacBook. Holding D only works on newer machines or ones with the factory HDD and OS X install. Once you format it it's gone. Kind of dumb IMO but that's how it is. Newer ones can use the recovery partition or even download AHT over the internet. Or Apple Diagnostics as it's called as of mid 2013.

If you have your original DVDs I'd give it a shot. It'll test RAM, GPU, logic board, CPU, and everything in-between.

As far as dirty video cards... Here's an Nvidia 8400 in our CNC PC. The whole PC tower was just sitting out in the open by the machine, and this is what happened over the course of a few years. Best part, it still works 100%. The only reason it survived is because the fan is on the bottom rather than the top. Ha! The CPU fan wasn't as bad as I thought it would be though. The only reason I got called out there was because the cheap rear case fan was rattling. o_O I've had my share of animal hair and smoke tar from my years in PC service and retail before going full time IT. Fun days, lots of crazy nasty stuff out there.

Good lord, it's created it's own mini desert and oasis! Thankfully mine has never reached such impressive Saharan levels.

Thanks for the advice. I'll try and find the original disks but in the meantime any opinions on using that latest Tech Tool Pro as a diagnostic tool for my problems?
[doublepost=1452379947][/doublepost]Just nipped off to look for the original disks - not holding out much hope thus far - and the blasted thing did the automatic restart business. Another, slightly different panic perhaps..

Hmm, "panic(cpu 7 caller 0xffffff8002816df2): Kernel trap" makes me feel like it could be memory related because I've seen this type of error with some bad DIMMS before. Or again, the GPU. The hackintosh community can sometimes be helpful because they get these errors all the time with unsupported video cards that aren't working right, thus why it could be the GPU still.

You could probably run Memtest86 on it. That would test the RAM at least without needing a disc. There are different GUI versions of it for OS X like Remember, though they haven't been updated in years. The good old Memtest86 live CD/USB should work though.

If all else fails, the 5K iMac is a mighty nice machine :)

That being said, we use a fleet of 2009-2010 Mac Pros that I manage at work and they still do their job very well. A couple have SSDs in them and 16/32GB of RAM along with some internal RAID setups and external RAIDs running off USB 3.0 cards all used for recording multiple streams of 1080i/60 that get used for broadcast and podcast use along with running Adobe Premiere and REAPER (DAW) and Pro Tools. They have a very heavy workload during the week encoding videos and bouncing audio projects and they haven't let us down so far for 5+ years. Almost 7 on some of them soon. They'll likely be replaced next year once we get some hardware recording devices in place but they are still great machines so it's worth it to fix them if possible and if it's cost effective. If a logic board or CPU goes out though it'll probably be retired at that point.
 
+1 for a very clever title....

At the darkest of hours all encouragement is gratefully received. Much obliged.

In the meantime am still looking for the blasted start-up disks. Needless to say another mad moment has just occurred...

I would check the CPU temperature and would remove and re-apply thermal paste. Just to be sure the CPU or it's backplate isn't the problem. Also remove all RAM and leave only the original that came with to make sure there is no DIMM problem.

Also check the battery on the motherboard if it's working ok or needs replacement.

I wish you luck!

Managed to get my old Tech Tool Pro to run tests on my three ram modules and according to that, everything is okay. Which isn't, I suppose, what I wanted to hear?

I really appreciate the advice VAG and am flattered by your faith in my technical ability. But sadly it runs no further than curry paste and the ability to turn things off and on. Adding and removing ram sticks and hard drives is really as far as it goes. And of course my dear old Mac Pro does make those tasks extraordinarily easy for an idiot like myself!
 
You can easily check temperatures and fan speeds with software like iStat or Monity.

Just remember to check figures are in Centigrade or Fahrenheit before making comparisons with others!
 
Have faith and patience :)

I recommend using MacFansControl to monitor the temps and see this video here to check how easy/hard it is to apply paste or upgrade CPUs.

Cheers!
 
Hmm, lots to think about. I did just watch the above video with my dear wife looking over my shoulder. I believe the phrase she used was 'Absolutely not'. One has to bear in mind that my house barely contains screwdrivers let alone a proper workspace. In fact the Mac Pro is adjacent to piles of antique books. The damage I could wreak would be wonderful to behold...

One further note that might help the sleuths amongst you. Whereas I can suffer various shutdowns just opening webpages Outlook and Aperture, my son seems to be able to play his 'League of Legends ' online without so much as a judder or interruption! Why on earth should that be the case?

Interestingly I just went onto the Monity app webpage. Every 4 seconds or so, each time the small inset image on their page changes, my fans audibly speed up.

Gave the Mac Pro a thorough clean today. Thankfully it wasn't too bad in there but sadly the problems have cropped up at the usual intervals today. Went searching for my start-up discs to run the AHT but still can't find them. I seem to have every other disc on the planet though. Even those belonging to my G4 iMac are all present and correct! I've even been in the loft to look in my pristine Mac Pro box to seek them out but no luck. One curious new thing did just happen though. I'd had my Microsoft Outlook open to check emails many times through throughout day but when I just went to open it again it opened with the 'Welcome to Office for Mac' greetings panel! I promptly closed down the Mac, restarted, and we were back as normal with all my emails. Does this point to anything it demonstrably can't be?

That issue could be permissions or bad drive.

It really is very easy to narrow this down to software vs. hardware. (I already told you how to eliminate GPU as issue)

Create or use a different start-up disc. Could be fresh install on a spare HD or just firewire in from another Mac. If using different startup drive fixes it, no hardware issue, just software.

Does your son boot WIndows to run LOL? If so, you already have your answer.

I wish it was! He actually uses the Mac version of LOL so no hope there. My problem is finding any friends who have Macs. I am a bit of a lone voice in the wilderness here! I do however have the AHT disc from my ancient iMac but I rather thought I should refrain from using that....
