Upgrading Mac Pro 2010 With New Graphic Card and SSD Drives

New expensive cheese grater

My beloved desktop Mac – a Mac Pro 5,1 – started exhibiting signs of an impending graphic card failure. After a few hours of use, patterns of visual artifacts made of little squares would fill the screen, the mouse curser would be replaced with text, and then the computer would become unresponsive. I could still use the various shared hard drives via other Macs on my Local Area Network, but eventually I would have to do a forced reboot1.

Mac Pro graphics card failure (probably)

A hard reboot like that is not ideal for many reasons, including potentially corrupting databases like my Lightroom catalog or my DEVONThink database or other issues. Luckily, I don’t think that happened, but it certainly was a risk. Eventually the graphic card probably wouldn’t recover after a failure, so I purchased a new2 card with a GPU.

The Mac Pro 5,1 aka The Cheese Grater, is a beloved Mac because it was engineered to be opened up and upgraded. The whole side panel pops off smoothly, the internal components are accessible, and some slide out if you need them to. I miss that era, to be honest, when computers were designed to be tinkered with. The current version of Apple locks away most components from casual tinkerers like myself, which is probably why I didn’t invest more money and upgrade the entire machine to a newer, in warranty, model, but instead just repaired the soon to be broken part.

I attribute this to Steve Jobs being involved in the design of the original Mac Pro, who knows, maybe even Jony Ive gave useful ideas? Whatever, the Mac Pro 5,1 is a delightfully engineered computer.

Opening Mac Pro Step 1

While I was in the mode, I decided to also replace one of the four internal “spinning” hard drives with a newer SSD style drive. My plan is to use it as the boot drive, once I’ve used Shirt Pocket’s SuperDuper! to copy all of the files from my current boot drive. This is taking forever and a day because I’m a digital packrat, and foolishly started copying before culling out some fluff that I don’t need on either drive. Oh well…

Again, the new part installed in minutes because the Mac Pro 5,1 was engineered to make installing and/or replacing hard drives easy – there are drive bays which just pop out when you toggle a physical switch, then just 4 little screws to put in the new SSD, push it back into the drive bay, and Bob’s Your Uncle

The plan is also to upgrade the Mac’s OS to Catalina3, maybe, or even just Mojave4 from High Sierra5, the currently installed OS sometime later this week. I have another SSD to install, this will hold my digital photography files and work files, replacing a “spinning” hard drive that currently is the repository for those.

Mac Pro opened

Final thought, my dual monitor setup isn’t going to work right away as I have to buy yet another dongle, a somewhat rare MiniDisplay Female to HDMI Male connector. I ordered one, reluctantly, knowing I’ll probably find a dongle somewhere in my messy office a day later. ¯\_(ツ)_/¯

Update 2/21/22

This turned out to be a more complicated project than anticipated because I didn’t follow the correct steps in order. I had to start over. Projects like this really makes one appreciate all the helpful information available on the internet. I was not a trailblazer in figuring this complicated process out, I’d bet most of the information was 5 or 10 years old, but still useful for me!

Here is what I did yesterday:

  1. Take out the Metal-supporting new graphics card, and install the old OEM card.
    1. The old card was a weird design for a factory installed card. It has an elongated plastic ring to the side which makes it too long, almost, to fit into the designated space. I really had to struggle to get it to fit, and as far as I can tell, there is no purpose for this design, at least for a Mac Pro 5,1. Maybe for some other computer? But weird because the card itself is short, only the sled holding the card was super long.
    2. the new card takes more power, luckily, there is an extra source of power just for this reason. Thanks Apple!
  2. Put a new HD (spinning) in sled, format, and do a fresh install of High Sierra from this Apple page. I don’t know if I really needed to do this, but I had a spare hard drive, and an empty slot to install it, so why not.
  3. Turn off SIP – this is where I got stuck earlier because the new graphics card doesn’t include a boot screen
    1. Reboot, holding ⌘-R6 to boot into Recovery Mode. This takes a moment, but eventually worked
    2. Load Terminal under the Utilities Menu
    3. Type: csrutil disable
    4. Reboot
  4. Install openCore following the simple steps7
  5. Remove old card, put new graphics card back in
  6. Update to OS Mojave via this Apple page on the new SSD drive
    1. Required updating firmware
    2. Load Install Mojave app
    3. Shut down
    4. Hold the power button for 2-3 minutes until the power light started to flash, and then a loud beep meant the firmware was updating
    5. I walked away, when I came back, I was at the High Sierra login screen
    6. Loaded the Install Mojave app again, and initiated the upgrade, easy peasy!

Right away after my first few moments in Mojave, 9 apps from the Apple App store wanted to update, plus several other apps not purchased from the Apple App store also. Yayyyy…

I may stay in Mojave for a while, looking at the Wikipedia chart of what Apple apps are included, I want to keep using iTunes instead of updating to Music. I’ve used both apps for a while now, and I still think iTunes is the better, more stable app. There is a hack to enable iTunes to be run on a newer MacOS, but I’ll wait a while for that.

Spending hours on a project like this is not wasted time, if the end result is successful. One feels a sense of satisfaction when the job is finished.

High Sierra

Apple Logos

For reasons, I did not upgrade my Mac to the current OS, High Sierra until this weekend. The new file system1 and its growing pains were the cause of my initial hesitation, but then inertia and procrastination took over. Oh, and that my laptop died after upgrading from the public beta of High Sierra to the Golden Master. Possibly a coincidence, maybe not.

Anyway, over the weekend, I cloned my entire boot disk2 using the essential Mac tool, SuperDuper!, and upgraded. If I wasn’t a digital horder, the clone would have been faster, but I am, so it was not. 

Once I had a complete, bootable copy of my main disk, I installed High Sierra. 

Quoting my request for help at a few Mac sites:

Afterwords, I could not load my Sound Preference panel nor get any sound to display.

Activity Monitor reported:
com.apple.preference.sound.remoteservice (Not Responding)

FWIW, I have a speaker connected to the optical digital port, plus I have an Apple LED Cinema display connected. Both worked fine before this morning.

Where do I begin to troubleshoot this?

I tried a Safe Boot, but same behavior, also logged in as another Admin user, same result. I also deleted com.apple.systempreferences.plist

By process of elimination, and by carefully examining Console logs, I found clues with audio .kext files3. I dug into both ~/Library and Library, removed all .kext and other related files for third party audio apps, including Rogue Amoeba’s Instant On.

Later, I found that Rogue Amoeba had blogged:

 

A small number of our users on High Sierra have experienced a loss of audio on their Macs, with no audio being heard from the computer. This problem can be caused by a conflict between High Sierra and an outdated version of our Instant On audio component (specifically, Instant On version 8.4.3). When Instant On 8.4.3 is installed on High Sierra, MacOS’s audio backend (CoreAudio) can crash, resulting in lost audio.

 

The conflict described only occurs when the outdated Instant On 8.4.3 runs on High Sierra. Well before High Sierra was released, we updated Instant On to fix the incompatibility. Instant On 8.4.4 (and up) has no conflicts on High Sierra, and users who are up-to-date will experience no problems on the new OS. While very few people will be affected by this issue, any number greater than zero is undesirable.

 

 

(click here to continue reading Rogue Amoeba – Under the Microscope » Blog Archive » Fixing an Important High Sierra Incompatibility.)

I then updated Audio Hijack to the latest version, and this fixed everything. Everything!

Yayyyyyy…

Keyboard Stops Working – Snow Leopard, Lion

Nike Control

I’ve encountered an annoying bug for a while now, dating from Snow Leopard (Mac OS X 10.6) at the least1 where my keyboard stops functioning. The mouse still works, the computer still does whatever it doing, but no key input registers with my Mac. The fix is simple enough, mouse into Activity Monitor, select Dock, quit it, and then the keyboard will work again. I haven’t figured out how to stop it from happening, but at least I can fix it without rebooting – which happened the first few times this happened.

I know that Screen Sharing and Spaces are both involved – the bug doesn’t appear unless I use these tools, in some combination, or in conjunction with some other process. Unplugging the keyboard from the USB port has no effect, plugging a new keyboard in has no effect, not using Screen Sharing and Spaces is not an option, so I live with having to quit Dock once or twice a day…

Don’t Steal Mac OS X Extension

As a means of procrastination, I followed these instructions to print out my desktop’s complete configuration, per these instructions:

Basically, it’s a printout of all the information that’s stored in System Profiler. Here’s how to do it. From the Apple Menu, select About this Mac. A new window appears. Click More Info to launch System Profiler. From there, select print and watch as your Mac prepares the System Profiler info for printing.

You’ll notice that it’s taking a long, long time. That’s because there’s a huge amount of information being compiled. Aside from the basics that we addressed last time, it’s grabbing every error log entry, vitals on every app you’ve got installed, network information and a whole heck of a lot more. When I ran this report the resulting document was 2.7MB and 500 pages!

(click to continue reading Mac 101: Comprehensive Mac system information.)

Mac OS 9 box

The resulting file was 830 pages, 4.2 MB large. Every application, every system extension, every font, every network configuration, every peripheral attached, etc. An extension called “Don’t Steal Mac OS X” amused me: wonder how it is ever triggered? I’ve never noticed it before1

32 Bit Photoshop


“Adobe Photoshop CS5 Upgrade [Mac]” (Adobe)

Photoshop CS5 runs natively in 64 bit, which means it is much faster finishing a lot of tasks, at least in my limited tests. However, some of my plugins no longer work. I clicked the “Open in 32-bit mode” toggle, and relaunched Photoshop, and AlienSkin’s Exposure 2.0 and my Epson Expression V500 scanner both appeared as options.


In order to see this checkbox, find Photoshop CS5 in your Applications folder, select the icon, click “Command I” (File/Get Info), and click the “Open in 32-bit mode” toggle button.

Slightly cumbersome to quit and relaunch Photoshop every time I want to scan something, but it will have to do for now. AlienSkin is updating their plugin, and it should be ready in a month or so, as they explain.

Photoshop CS5 Compatibility

Now that the Photoshop CS5 excitement is at a fever pitch everyone wants to know whether our products are compatible with it. The short answer is yes, the current versions of all our products work with Photoshop CS5. However, you need to run CS5 in 32-bit mode for all of our Mac products and some Windows products. Also, the floating panels we have released with some of our recent products will probably not work in CS5. Below is the plan for making all of our products fully compatible with the 64-bit version of CS5.

Exposure 3 and Bokeh 2 are almost done and will be 64-bit on both platforms. Exposure 3 will ship in June

But given that most everyday users have no idea which of their apps are Intel-native and which are PowerPC, this seems unnecessarily harsh.

  • CBS Falsely Portrays Stanford as Democratic Scandal – But as Public Citizen, Huffington Post, ABC News and Talking Points Memo all reported, Stanford and his Stanford Financial Group PAC contributed to politicians and political action committees of both parties (including $448,000 in soft money contributions from 2000 to 2001 alone) to advance his agenda of banking and money-laundering deregulation. Many others journeyed on Stanford's junkets to Antigua and elsewhere, prompting TPM to brand his company "a travel agent for Congress." (TPM has a slide show of one of those of Stanford getaways.)

Those stories have been told. I want to write about our friendship. The public image was that we were in a state of permanent feud, but nothing we felt had anything to do with image. We both knew the buttons to push on the other one, and we both made little effort to hide our feelings, warm or cold. In 1977 we were on a talk show with Buddy Rogers, once Mary Pickford's husband, and he said, "You guys have a sibling rivalry, but you both think you're the older brother."

  • Daily Kos: Chocolate Covered Cotton – billmon – The fatal innovation…was the rise of so-called collateralized obligations, in which the payment streams from supposedly uniform pools of assets (say, for example, 30-year fixed prime mortgages issued in the first six months of 2006 to California borrowers) could be sliced and diced into different securities (known as tranches) each with different payment characteristics.

    This began as a tool for managing (or speculating on) changes in interest rates, which are a particular problem for mortgage lenders, since homeowners usually have the right to repay (i.e. refinance) their loan when rates fall, forcing lenders to put the money back out on the street at the new, lower rates. This means mortgage-backed securities can go down in value when rates fall as well as when they rise. By shielding some tranches from prepayments (in other words, by directing them to other tranches) the favored tranches are made less volatile and thus can be sold at a higher price and a lower yield.

Snow Leopard

On Site Support

Interesting, if true. Leopard hasn’t been out that long. We still have 3 PowerPC computers on line (plus a Yikes G4 PowerPC in use, pending a transfer of the Now Contact and Up-to-Date server and main database, if the vaporware, Nighthawk ever gets released.) Performance gains on the Intel Macs would be welcomed however.

The next version of Mac OS X is code-named “Snow Leopard,” and will indeed be Intel-only, we have learned. This info is hot on the heels of TUAW’s original scoop about Mac OS X 10.6 being readied for shipment as soon as Macworld 2009 and being Intel-only.

People familiar with the situation have confirmed to us that TUAW’s details are true—Snow Leopard is currently on track to come out during next January’s Macworld, and it will not contain major OS changes. Instead, the release is heavily focused on performance and nailing down speed and stability. With Apple’s current (and future) focus on smaller, thinner, and more mobile devices, this move makes perfect sense. Things like the MacBook Air, iPhone, iPod touch, and other mysterious devices that have yet to be announced need better performance for better battery life, and that’s definitely something Apple wants to excel at in the years to come.
