Best spec's on pre-touch bar MacBook Pro with C1

Nick Burchell
I'm needing to upgrade my 2012 MacBook Pro, but after hearing from colleagues and digi-tech's, I'm planning to steer away from the touch bar models. What specs should I be looking at for C1, specifically CPU speed and video card in the 2015, 15" model year.

Thanks!

    There are some hints on the web, a 32GB Ram'ed version MBP is on the way. (Apparently somebody did a Geekbench test)

    I have a late 2013 MBP Retina 15" with 16 GB RAM and NVIDIA GeForce GT 750 M/2048 MB (getting old !!) and it works fine with C1 v11.1.1 and a 20,000 pics catalog.
    I won't switch at all to a butterfly keyboard !!

    The current '2015' model only sells with intel integrated graphics, which in all honesty is better, as it's much less likely to burn up.

    Yes, steer clear of the failing butterfly switch keyboard. (I think Apple removed key repeat from MacOS to hide this)

    Ah, this is where I'm trying to find out about the best configuration. There are still some 2015 MBP's available with both the AMD Radeon R9 M370X and the Intel Iris 5200 video cards. I believe the "new" 2015's Apple and B+H are selling just have the Intel Iris. Have there been issues with dual card MBP's overheating or having slow down issues? C1 recommends "Dual (matching) Graphics card from NVIDIA or AMD with 4GB+ RAM per card"

    Thanks

    I recently worked on a job using a Mid 2015 15" MBP, 2.5GHz i7, 16gb ram, AMD Radeon R9 M370x 2gb & Intel Iris Pro 1536mb graphics cards. We had 2 Eizo monitors connected but it could only run one of them plus it's own retina screen so we ended up running the 2 Eizo's with the laptop closed. Other than that it did great during a full day of high frame rate 1DX mkII work.

    Speedy previews, no slow downs, crashes, or hang ups running CO11. It was happy, I was happy. This was all tethered capture, I didn't do any retouching or processing out of the images on this machine so can't comment on that.

    Since conception.

    To mention a few for Intel MacBook Pros:
    There were the faulty Nvidia chips that were too sensitive to heat/cool cycles (~2007, issue varied between a few months to a couple years to show up. It was mistakenly associated with the myth of the package lead-free BGA cracking, when in fact it was a bonding issue between the chip and the substrate).

    From 2008-2013 you still had some chips burn up, but the most common issue is the under-rated capacitors (C7771/C9560) that Apple used in the GPU power rail; which will eventually destabilise power or fully short-circuit.

    From 2012-2015 (Retina) the GPU power driver IC (U8900) was improperly soldered, almost on purpose you'd say, and Apple '"repairs"' it by wedging a piece of rubber to force the chip to make contact with the board, instead of properly reflowing it with quality solder.

    Also, Apple has recently sent out a firmware upgrade so that the machines that haven't died yet, don't turn the fan on until they are burning.

    2016 and onwards are already showing some serious faults like the USB-C power negotiator that goes bad on the 12" MacBook, the failing keys on all butterfly keyboards, and I'm sure there will be more design flaws coming up.

    Yeah, that's not practical for most laptops. I find that C1 runs remarkably well on my old Intel HD 4000. Try asking your local APR or Apple store to let you run some tests.

    Yes, that's an arbitrary lane limitation of the Intel graphics. (The dedicated GPU still has to output through the intel circuitry, hence the limitation.)

    I have my MBP Retina 15" since more than 4 years now. There are two GPU in it (the Intel Iris chipset and the NVIDIA GeForce GT 750M 2 gb) and I haven't had any burn up until now. I hope I won't have one before long....

    The buck converter solder issue is exacerbated by frequent (normal) flexing of the machine. If yours is handled particularly carefully it might not even show up. The GPU's in those are actually ok, but again, the fan matter ensures their life expectancy has already peaked.

    What would it take for a macbook to run 3 monitors (its own plus 2 external)?

    The HDMI output in these machines is one to two DisplayPort buses wired together in a hybrid mode (TMDS signal conversion done in the chip, but still uses the DP lanes to deliver, which impacts native DP significantly). So if you use HDMI + 2x DisplayPort (retina screen + extra monitor) it will have trouble maintaining signal integrity or flat out refuse to accept that 3rd screen.

    Theoretically, if you have two monitors of the same resolution (same pixel clock and bit-depth), both on DisplayPort, (and cross your fingers) it should work.

    An eGPU would be the way to go otherwise (if you get it to work on Mac in the first place).

    I'm going by understanding of the architecture, and not much by experience with macs (haven't had one in a while), so take what I'm saying with a pinch of salt.
