  1. Hi guys, i have one Macbook pro 13 Retina Late 2013 and he have broke EFI (BIOS) chip, i solder him out and make original dump back up via my mini programmer, all what i need good and clean EFI dump for my mac.Info about my system: Macbook pro 13 Retina Late 2013Model: A1502EMC: 2678Motherboard model: 820-3536-APlease help me to find that file, apple.com doesn't content anything like that, i don't need BIOS update file with .dmg extension,i need .bin with dump and of course without EFI lock.If people are interesting how to do that i can make post with photo and explanation how to open, disassemble, and chip programming.
  2. Hi there, lots of useful info on here! Still I need to ask a few questions as my setup isn't quite working! I've a 2012 rMBP on El Capitan 10.11.2 and I used the automate_eGPU.sh script to quickly sort out the modification of files and installation of NVIDIA web drivers. I'm testing it with an NVIDIA GTS450 which is connected via a Sonnet Echo Pro and PE4C 3.0. SW1 is set to 2 (PERST# delay 9.8sec), SW2 to 1 (CLK no delay). It's picked up fine in OS X and I can drive an external monitor with it no problem. However, it doesn't appear to be doing any rendering - all the legwork is still being done by the internal GT650M!!! It shows each screen as being driven by the GT650M in About This Mac, and testing with games seems to corroborate this. What gives? I can't find any examples online of other people who've had this problem (at least in OS X). The GTS450 is correctly identified in System Information. A second question... I know there isn't a way to get the output on the internal LCD on Windows on this Macbook due to it having a dGPU and Apple's rubbish firmware, but is that the case in OS X? The Intel HD4000 is accessible there, does that mean I could funnel the graphics back to the internal LCD or is it just impossible on all counts?
  3. This isn't even my final form! "DotPusher III" Hardware: Mid-2014 MacBook Pro (15-inch) Core i7-4980HQ (2.8 GHz) NVIDIA GT 750m NVIDIA TITAN Xp 12GB (GP102-450) (previously 980, 980 Ti) Also tested with: EVGA GTX 1080 SC (see bottom of post) Akitio Thunder2 Corsair 550w ATX PSU "Fat .50" Ammo Can (800 rd 5.56mm) Software: Windows 10 Latest macOS version automate-eGPU.sh rEFInd Boot Manager apple_set_os EFI application Tools: Screwdrivers Channel-lock Pliers (or vise grips) Jigsaw / Dremel / Angle Grinder / Metal File / Sandpaper The Build Honestly, the build was surprisingly simple! Popped open the Akitio, used channel-lock pliers to pry the front side of the Akitio open to allow for the length of the GPU. Added gaff tape over all of the metal parts, just in case the card came into contact with the bare metal of the bent Akitio enclosure. Got the card handy, a gorgeous little reference model GeForce GTX 980. On a side note, I actually had an MSI GTX 980 GAMING 4G but ended up trading it for this reference unit, as it was one of the ugliest pieces of hardware I've ever seen, and the reference models are just beautiful. (Form over function, but isn't that the Apple way? :P) The card slotted right in, no problems here. Next up was the power supply. I used a Corsair 550w unit, but cut everything besides the two PCIe power connectors and the CPU 12v rail (to power the Akitio). Terminated all the ends with shrink wrap and gaff tape on top of that, and taped all the unused lines down to the side of the PSU. It was also during this step where I hotwired the PSU to always be "on" via the paperclip trick...except I just traced those wires back to where I was going to make my cut, and soldered them together. For the Akitio's power, I used the molex-to-barrel-adapter guide, but instead of being patient and getting a proper barrel connector with two leads, I cut the barrel connector off of the Akitio's power supply that came in the box. I like to live life in the moment, I guess...but the fruits of my labor were revealed when I stripped the wire and it turned out to be coaxial instead of side-by-side! No matter, I said to myself, as I twisted the outer fibers into a solderable piece of wire, and stripped the inner wire as well. Verified polarity via a multimeter, and soldered the Akitio barrel connector to the CPU12v line from the PSU. A bit of shrink-wrap and gaff tape later, and I had a nice little feed for the Akitio coming off of the PSU. No powered riser bs, no extra Akitio power supply. Clean and simple. PCIe plugs went straight into the GPU, I gave em a little bend so they'd hug the edge of the magazine holder. I also re-routed the front LED from the Akitio's box around the back of the PCB to where the Akitio power plug is, so that that area of the magazine holder lights up blue when the card is active. At this point, I took the magazine holder and made cutouts for the GPU ports, ventilation, and PSU ventilation. Covered the rough edges with gaff tape so they wouldn't fray and get sucked into a fan (plus it looks a bit less janky). The Akitio with GPU slid perfectly into one side of the magazine holder (make your measurements first before going shopping!), but was sitting too low for my cutout to be centered on the GPU's cooler...nothing a little packing foam (from the Akitio box!) couldn't fix. The PSU slid in with...some effort. From my measurements, I knew the PSU wasn't necessarily going to fit, but it was close enough that with a bunch of gaff tape to keep the bottom and sides secure, it doesn't move anywhere and there are no signs of any danger of it falling out after a good 2 weeks with the setup. I just try to keep this side hidden, it's pretty garish. EDIT 070416 (MURICA DAY) Added green underlighting because #AMDsux #teamNVIDIA (lol). Here she is at work (literally, at my work), powering 2x 120 Hz displays & a bunch of OpenCL compute. The Experience It was time to start her up. Plugged in PSU, switched it on, plugged my 4K 60Hz monitor into the eGPU, plugged the TB cable into the Mac and hit the power button. Fired right up, booted into Windows and re-installed the NVIDIA drivers. After a reboot, the card was recognized, and I was playing Doom (2016) at ultra quality 1440p inside of 10 minutes. Not too shabby! I spent some time in MSI Afterburner, customizing a fan curve to keep it pretty quiet during moderately high gaming workloads, but ramp the fans up quickly if the temperature went north of 70º C. Boy, this thing is loud when the fans are at full tilt, but I'm glad they; the reference cooler is no slouch, and with fans cranked to max it's actually able to pull down the temperature from 80 down to 70 while furmarking! With a bit of tinkering, I settled on a final, furmark-for-8-hours-stable overclock of +225 MHz core, and 7400 MHz on the memory. Using ThrottleStop, I also undervolted the i7 in the laptop, and downclocked it to ~2.4 GHz. Windows runs a bit hotter than OS X, figured I'd help out as much as I could. I gotta say, it feels good to put down an 80th-percentile score in 3Dmark Fire Strike with a MacBook Pro. On the OS X side of things, automate-eGPU.sh took care of everything without a hitch. I did notice some weird stuttering every second (and exactly on every second), but with some tinkering I found out that the "Displays have separate spaces" option was the cause of the issue. Disabling it made OS X run perfectly smoothly afterwards. Final Cut Pro X immediately took advantage of the new GPU, and I was able to play back Sony FS5/A7s 4K footage with a few layers of colorgrading on it much smoother than with the 750m. It can almost handle playing it back at full-res, which was just astonishing to me. Analyzation of footage for stabilization just rips, along with optical flow retiming. Adobe CC was able to take advantage of the card as well, Mercury Playback Engine (CUDA) felt much smoother than on the 750m, though I haven't been using Premiere in a while so I didn't do much testing in CC. Unfortunately, After Effects is not really accelerated by the card, but oh well. To get Optimus to work with a 750m-equipped MacBook Pro, I turned to this reddit thread detailing the installation of rEFInd and using an EFI utility called apple_set_os to get the Mac to expose the Iris Pro when booted into Windows. I also customized the rEFInd interface because the default skin looked like something out of Mac OS 7.5.3 (I half expected little puzzle piece extension icons to start loading across the bottom). The reasoning for using apple_set_os instead of the built-in spoofing feature in rEFInd is because I'd like to normally run Windows without the iGPU enabled, but retain the ability to switch into "Optimus mode" when I'm mobile. My full boot/setup process for mobile gaming via Optimus, coming from normal eGPU usage with external monitor is as follows: Leave eGPU unplugged Boot into Windows Disable the 750m in Device Manager (I usually leave it enabled when booting Windows normally) Run the switch-GPU script to set the iGPU as primary Shut down Windows Plug in eGPU and start the computer Select apple_set_os (I've renamed this to "iGPU Enabler", the far right icon in rEFInd) Boot Windows If all goes well, I'm in Windows with the GTX 980 as the Optimus "high-performance NVIDIA processor". Game performance takes a bit of a hit, but not anything significant...I can still play most titles at 1080p ultra quality, and they look great on the MacBook Pro's retina IPS display. Lingering Issues Thankfully, all of the lingering issues I have only involve the boot process. Sometimes the entire system refuses to POST (sits at a black screen without ever chiming), and I have to hold the power button for a few seconds and try again. When it does POST though, the next hurdle is whether the driver (in OS X or Windows) will initialize properly. Sometimes it doesn't want to play nice, and I'll get a BSOD on booting Windows with DRIVER_IRQL_LESS_OR_NOT_EQUAL, but a restart or two will do the trick. FIX FOR BSOD ON BOOT: I figured it out, a trip to Device Manager and I noticed there was a "show hidden items" menu option. Clicking that revealed that I had two GTX 980 devices that weren't connected for some reason, and the driver was fighting itself upon initialization during boot. Rebooted into Safe Mode and ran DDU to clean out the NVIDIA driver, reinstalled it in normal mode with the eGPU connected, and all is well. One GT 750m, and one GTX 980 in Device Manager when viewing hidden devices. If you're having driver issues like I did, you might want to check this. (NEW) FIX FOR macOS NOT BOOTING: Run Goalque's script in "-a mode". This alters something regarding the thunderbolt chipset on every shutdown, so when rebooting back into macOS, the eGPU will initialize properly every time. For OS X, I just get a black screen with my monitor showing no signal input. Again, a restart or two fixes this. (Honestly, I've had the NVIDIA Web Driver do this with the internal 750m, so it's just a normal driver-crashing-on-init issue, not specific to the eGPU.) But once the system is booted, it is rock solid, and I've never had anything crash or fail (besides overclock-induced crashing in Windows, but that's my own fault). It all seems to be based on luck of the draw, as I'll have some days where it'll work flawlessly and I'll be bouncing between the two OS's with no problem, other days I'll get 8 failed starts in a row. If anyone has any idea how to help mitigate these failed starts, I'm all ears. The only other issue I can think of is lack of display brightness control when running in Optimus mode (anyone got any clues?), but it just means I have to set the brightness from within OS X first before going through the boot process. Final Thoughts It was totally worth it. I'm in love with this setup, it truly feels like the best of both worlds. The i7-4980HQ in the MBP is no slouch of a CPU, the only thing my setup was missing was some graphics horsepower, and the GTX 980 more than comfortably steps up to the plate. My work experience has had amazing fluidity, and gaming has gone from sub-720p resolutions on the latest titles to gorgeous looking, maxed quality 1080p and higher. Less demanding titles (CSGO, Borderlands Pre-Sequel) even run at 4K 60fps, which is a sight to behold. The Oculus Rift that I got my hands on runs perfectly smooth, with no VR-sickness to speak of. And all this, in a "portable" setup. I now have 3 levels of portability (with associated levels of performance): full desktop mode, Optimus (so I don't have to lug a monitor around to LAN parties or remote editing / rendering of CGI), and of course the laptop by itself (which, with its Core i7, is still no slouch, at least when it comes to CPU compute power). It's also extended the longevity of my machine a lot, since I was looking at the 2015 and purported 2016 models for their GPU upgrades...but not anymore! The only thing I'm looking at is the moment NVIDIA releases Pascal drivers for OS X...and my poor wallet might have to take the brunt of a GTX 1080. The Future I'm still on the hunt for a better case, but all of the computer cases I've found are...well, computer cases, and far larger than this magazine file setup. So I'm looking at...different solutions. An old army surplus ammo box looks like my next case, and it has a handle at the top, which I can't live without after having this magazine file for a couple weeks. I'd love to pick up a modular SFX PSU so that the PSU actually fits into the magazine holder without any modification necessary, and if it's modular, it'll help keep the cables clean and tidy, with no drive and fan power cables to cut. Hope you guys enjoyed the adventure, and that some of the solutions to the little quirks I found help out someone! Happy eGPU-ing! --- EDIT 070416 (MURICA DAY) Just for kicks, slapped a buddy's GTX 1080 into the chassis to test with Windows. It required a driver reinstall as the system didn't detect the 1080, even after rebooting...it seems that the NVIDIA driver enumerates the cards in your system at install time and will only install the drivers it needs to, not all of them (different from the way OS X does it). The driver install worked fine without having to run DDU and cleanly install. YMMV though. The added compute power of the GTX 1080 was more than welcome to help mitigate the performance hit you take when using Optimus. Crysis 3 ran at the laptop's native resolution (2880x1800) at around 45-60fps with all settings cranked. Beautiful. I was really looking forward to testing out Rise of the Tomb Raider on it, but ironically there's a bug with Pascal cards and NVIDIA VXAO, so I couldn't get a fair comparison. Wish I could keep it, but the lack of Pascal drivers for OS X keeps me on the 980. For now. EDIT 071816 Acquired a "Fat .50" (actually an 800x 5.56mm) ammo box and made the primary cuts using a pneumatic angle grinder + cutoff wheel. Test fitted the Akitio and PSU. Currently need to drill the PSU & AKT mounting holes, but also trying to figure out what thread pitch the Akitio's mount holes are (anyone got a clue?). Specifically, the ones that the Akitio's own case's captive thumbscrews screw into. EDIT 072016 Finally finished the ammo can case after much measuring, cutting, and drilling. As the barrel plug was going to be flush against the side of the case, and I didn't want to have to loopback the cable like I did in the magazine file, I ended up soldering the CPU12v rail to the back of the Akitio's PCB. Pre-tinned the wires and plopped them onto the PCB, then secured it with gaffer's. Verified the correct solder points thanks to /u/Dippyskoodlez, who found the info from these very forums. Singed the PCB a bit, but oh well, close enough. EDIT 050517 NVIDIA released Pascal drivers for macOS. Upgraded eGPU to a TITAN Xp. Benchmarks available upon request. Yes, it's completely a ridiculous setup now—I was only able to upgrade due to external circumstances. Diminishing returns starts to creep in (even for the much-more-fairly priced 1080 Ti) due to the TB2 bottleneck.
  4. Goodmorning everyone, I am happy owner of the object in title for 3 months. After a while I purchased a Thunderbolt 2 disk Lacie d2, 3TB. Right from the start it is ALWAYS been a pain to make it work. Often the hard drive is blinking, and the Mac does not see it, or even it doesn't turn on. After frequent rebooting, prayers and other tricks it maybe works, otherwise I have to use it via usb3. Tried to reset anything .. smc, nvram, the Mac itself (initialized) .. but nothing to do. Maybe you do not have the problem for a couple of times, then there falling back. I also tried changing the connection sequence (the Lacie instructions say to first connect the tb, then power the unit) I also went to the Genius Bar, but the outcome was always the same; after n trials, it all seems ok, then bang. I'm afraid it is a PC problem .. probably it's the same problem that randomly freeze my mac into boot for many seconds, then it wakes up like nothing (Tried to leave it work, often it takes a minute to start!) HW specs are Intel Core i5 (I5-4278U), 8 Gb RAM 1600 MHz DDR3L, Intel Iris 5100 Help == EDIT === 25-10-2016 Another visit to the genius bar .. this time I was told that it could be to change the logic board, because the TB2 circuit could be damaged. The fact that it works after reset nvram / smc may suggest an incorrect current distribution. Some idea? I want to clarify once again that when they work, I have NEVER had a problem .. disconnections or similar .. Basically I was told that the repair would be more than half of the Mac, so you might as well keep it and use the USB. The hardware diagnostic told that everything ok, though.
  5. Hi guys, I'm new to this forum, Mac world and also to eGPU world! So I decided the better thing to do is to put my hands right into the mud.. I purchased an used, original Akitio, a Palit GTX970 JetStream and a cheap Micro ATX PSU (Vultech GS500M) - My pc is a mid 2014 MacBook Retina with Windows 10 and Sierra (I5 2.6 GHz, 8Gb RAM, Intel Iris 5100, 256Gb SSD). First thing first, I prepared the PSU to power all the things. The datasheet says it is a 500w, with two 12v rails, 29A total (348w). I cut all the connectors, isolated the other lines I won't use (3.3, 5v, 5vsb and -12v), shorted the power on with a negative. Then I had six 12v positives, and all the commons. I gathered 4 wires and solder them to the positive of the two PCI 6 pin cables, same I did for the negatives, except two. I used the remaining wires (2 positives and 2 negatives) to make the barrel connection for the akitio. Tested without anything plugged, it works (fan spinning) Then I build a plexiglass enclosure to contain everything, i kept the layout of the original metal case, so the position of the board is the same; next to the video card, on the opposite wall I planned to install the psu, with the air intake obvously facing the outside, and the air output in the rear. In the front I installed a 120mm fan, plugged into the fan port of the Akitio board. I partially assembled all the parts, leaving the top and the right side (opposite to the board, to be clear), and power on. Surprisingly, nothing blew up... I managed to make the card recognized by Windows, installed the drivers, AND make some gaming - benchmark test to test the setup. I made a short session of Farming Simulator 2015 and suddenly nothing wrong .. BUT .. after some minutes the PSU started to buzz. The more the card required power (by doing some "complex" tasks), the more PSU buzzed. I also tested with Unigine Valley, in ultra setup. Everything worked, I made two benchmarks, I reached 85°C on the GPU and 96° (WOW..) on the CPU.. And now.. my concerns.. - is the PSU buzzing just because is sh*tty? Or I made some terrible mistake by wiring, soldering and so? I took a look inside it and TBH.. even if I don't know electronics so deep to reverse engineering I noticed that 12v wires come ALL from the same pad on the pcb.. so I guess it's not a problem to put them together. If the power table is correct .. I should get nearly 350 w from the 12v line .. during the benchs I logged the power consumption with HWINFO, and the 970 drew about 120w on its peak .. if summed with the Akitio I get less then 200w .. far more behind the limit.. - the temperatures .. ok 85° in full load would not scare me if the GTX was inside my good old desktop gaming rig .. but here I think the game is different, is there any risk to "cook" the Akitio Board? The space between the card and the board is really low (I'm not using a riser), I'm thinking about improving the ventilation by drilling many holes in the wall very next to the board, and maybe installing a more efficient fan connected directly to the 12v. Would it be ok? - the riser .. TBH I don't really know if I need the riser or not. By now the card is plugged directly into the Akitio Board, powered by the buzzing PSU, that also power the board. Everything works even if the mentioned troubles above. Any kind of suggestion is accepted, last things to say, I'm quite able to solder and etcetera. I own also a Dell DA2, but I preferred to make an "everything integrated" solution and last but not least .. JetStream GTX970 on review peaked quite 200w itself. I need more power, I guess. Ok I'm risking to be lynched .. but just to know .. I decided to mod directly the PSU by following a guide taken on the web .. stupid or not it's not my invention I attach a pic of the connection I made, of the PSU board and the power table Here are some pics of my setup .. on idle and with low gpu load it's running fine, no buzz BUT no load .. tested again Unigine and here are the results (AGAIN the psu is buzzing). Respect to the post I modified the case by drilling holes behind the Akitio Board, drilling the psu case, and most important, I dressed the power wires of the akitio board with a silicone-fiberglass sheath to protect it from the heat produced by the gpu. Again, thanks.. any hint would be appreciated.
  6. Hello all, I recently put together my egpu configuration using the video below down to a T. Every part of my set up is in this video and I've done exactly like this guy has said to make my set up. I've gotten my egpu to work finally by plugging in the thunderbolt2 cord when both the MacBook and egpu are powered down. Then I power on my back into the selection screen to choose windows or mac. Then I turn on my egpu and hope for the best. I've found this works about 30-40% of the time so if someone has a way to increase my chances feel free to comment. I'm using a MacbookPro 13in Retina with dual core processor and Intel Iris 6100 (Late 2015 MacBookPro 13in retina). Anyways once I am booted into windows (I'm using windows to use the egpu on the internal screen because this was meant as more of a mobile device) and I've checked the device manager to make sure the gtx960 is working properly (sometimes I get "no drivers are installed for this device and I have to reboot and try again) I try and run a game. I use WoW as a test for my graphics card. I have msi afterburner installed and I play WoW off an external HDD since I have the 128gb version of the MacBook pro. When the graphics card is working and I'm playing a game for a while the game will suddenly crash and I'll get the BSOD with the error NVLDDMKM.SYS. Does anyone know how to fix this error? Other than that the fan boots up when at 60degrees Celsius like it should. I'm using windows 10 with the driver 369.90 for nvida which is the most recent so if anyone has a fix for this error it would be greatly appreciated. Thanks!
