  1. Hello community! I searched everywhere, but couldn't find tables from one or both of these two macbooks, if someone here has these models, please, could you share the acpi tables with me? I really need them. Thanks
  2. PREFACE I’ve used a 2015 15” MBP as my main system since it was released. I do photo and video editing in the Adobe suite regularly and have been eyeballing the performance of the latest MBP models. I’m on the road all the time, so a laptop is basically my only option. After the whole mess with the CPU VRM hardware flaws being made apparent by the poor power management profile shipped at release with the 2018 i9 MBP I’ve been more weary of the hardware design of MacBooks. That’s before I account for losing all USB-A ports, losing the SD card slot (‽), losing reliability and tactility of the keyboard, and losing the ESC key to the touchbar; if I compare the 2018 MBP to my current 2015. Given these flaws, I have been researching the performance situation comparing the 2018 MBP to the X1 Extreme, XPS 15 9570, and the Razer Blade 15 2018. These are essentially the only options for a road warrior that needs a high quality panel and the best CPU and GPU that can be crammed into around 4lbs (1.8kg). I used to use a ThinkPad T42p and loved it when it was new. So fast forward to now and the release of the ThinkPad X1 Extreme. It’s a truly tempting machine for an artist, given that the 4K UHD version offers just about the best color gamut available on any laptop panel. I get back the USB-A ports, get one of the fastest SD slots on any laptop, and get one of the best laptop keyboards on the market. That’s before even considering power management and modularity. I’ve been dabbling in learning Machine Learning, so a system with an nVidia GPU (CUDA) is a bonus on that front as well. For me the best color reproduction on a high resolution display panel was most important. The X1 Extreme has that, so I’ve ordered one. I got it with the fastest i7, base SSD and memory, and have separately purchased two 1TB Samsung 970 Pro M.2 SSDs and 2x16GB DDR4-3200MHz memory (just in case it’s possible to overclock the memory on the X1 Extreme). I got the system for $2,100 from Lenovo USA, and the SSDs ($390 x 2) and memory ($330) from Amazon US for a total of ~$3200. These are easy to install on the X1 Extreme as the bottom cover is easily removed to reveal the M.2 and SODIMM slots. To compare, the 2018 MBP with the fastest i7, 32GB memory, and 2TB SSD is $4400. So I can save $1200 and get a faster system (on all counts) with a better panel and better connectivity by going with the X1 Extreme. The only thing I’m compromising is losing the big beautiful haptic touchpad and a bit more refined hardware aesthetic. Though, to be honest, I’ve kept a big thick dual-layer Tech21 case on my 2015 MBP. So I’ll actually be going down in volume and weight by moving to the more rugged ThinkPad. I think I can live without the touchpad. Oh, by the way, the 4K UHD panel of the X1 Extreme has touch and decent pen support! Another bonus vs. the MacBook. Though I keep a 12.9” iPad Pro around for my pen work and can’t imagine using a laptop similarly. It’s still nice to have a laptop screen actually respond when I go poke at it accidentally after switching back and forth between laptop and iPad. TOPIC So I want macOS with proper discrete GPU support on a 2018 MacBook class laptop. That’s not possible on a pure Hackintosh as things stand, but via a macOS virtual machine it looks like it could work with what looks like some relatively bleeding edge support of PCIe UEFI passthrough. People have been doing this on Linux hosts to Windows VMs with some great success recently: https://gist.github.com/Misairu-G/616f7b2756c488148b7309addc940b28 And it looks like that’s coming for macOS VMs as well: https://github.com/kholia/OSX-KVM/blob/a4fb2fd5aae871bdbc371b0cd31d4d8129d0f9ac/UEFI/README.md The X1 Extreme, XPS 15 9570, and Razer Blade 15 (2018) are essentially direct competition to the 2018 15” MBP. I would really like to see these three systems get some nicely fleshed out guides for getting maxed out compatibility and performance in macOS running in a VM for these systems. When I get my X1 Extreme I’ll start working on it for that one. I will post updates here. I hope to inspire others with the other two systems (or looking to get them) to do similarly. 15” MACBOOK CLASS LAPTOP COMPARISON I chose the X1 Extreme largely because of the excellent 4K UHD HDR panel (100% of 2D AdobeRGB and 85.5% of 3D AdobeRGB, basically unparalleled), good mix of thermal performance and noise management, and overall ruggedness and connectivity. If I were a gamer I would go with the Razer 15, but the fast low-gamut 1080p panel just doesn’t work for my purposes. If I were most concerned with aesthetics or battery life (97Wh battery for it vs 80Wh for X1E) I would go with the XPS 15. I am aware that the second 2018 refresh of the MBP is coming ~Nov 14, with the new AMD Radeon Pro Vega 16 and Vega 20 GPUs, and it looks like the latter might offer up to a 60% performance boost over the Radeon 560X. Maybe it has even given Apple enough time to update the CPU VRM along the way. This could make the performance picture more comparable for the 1050 Ti based X1E and XPS 15. I believe the 1070 Ti based Razer 15 will still win out though. Still, if you compare the fan and heat pipe solution put into the X1E vs the MBP the MBP just looks wimpy in comparison. MBP has smaller fans, less venting, and only one (smaller, thinner) heatpipe. It’s also more difficult to access if you want to put a better thermal paste or liquid metal on it. Put simply, the thermal hardware on the MBP is basically the same design for the last 3 years and it can’t keep up with the hex-core processors. So even with the Volta 20 GPU making the MBP competitive again on the graphics end, the MBP will still be falling short on the CPU performance plane. This is before we even look at tuning options. Getting into tuning, it’s possible to improve thermal performance of all the laptops in this class by around 15-20% by using either a best in class thermal paste like Thermal Grizzly Kryonaut or (if you’re willing to deal with all the caveats that come with using a conductive fluid that permeates other metals) a liquid metal interface like Thermal Grizzly Conductonaut. The liquid metal gives you the best possible conducting interface, and the paste is more forgiving and easier to apply. Further, it is often possible to stably undervolt the Coffee Lake i7/i9 available in this class of systems to further improve performance, thermals, and power consumption (generally another 10+%). Apple has deliberately made it impossible to undervolt the CPU on the MBP! This has been true since the first Skylake CPUs a few years ago. You used to be able to use a program called Volta to undervolt your CPU on macOS. This is a huge peeve for me and, combined with the general power and thermal underdevelopment, is one of the main reasons I want to get a competitor’s hardware. As a primer, the default voltage of modern CPUs is typically set conservatively high for the sake of production efficiency. With the current generation Coffee Lake CPUs it is commonly possible to set the CPU voltage about 100 to 150mv lower safely. This allows the CPU to run cooler and consume less power. For laptops which are thermally limited (basically everything in this new 6-core 14nm era), this also translates into better performance. It’s a tweak that actually improves reliability of your CPU. So it’s just stupid that Apple has deliberately made this impossible. Shame on them, someone else take my money. Wrapping up, my biggest quibbles with the X1E (before actually getting it) are that the 4K panel’s responsiveness is about the slowest I’ve seen on a modern panel, and it’s just really not suitable for gaming. There’s also what I consider an annoyingly high level of backlight corner bleed that I’m sure will be distracting during blackboxed video viewing. Hopefully these two issues will be fixed in next year’s iteration. FOOTNOTES MacBook i9 Thermal / VRM (below-baseline throttling/thrashing) Issue: https://www.macrumors.com/2018/07/24/throttling-i9-macbook-pro-power-delivery-chip/ https://www.kitguru.net/lifestyle/mobile/apple/matthew-wilson/macbook-pro-2018-throttling-fix/ This was mitigated with software that works around the poor hardware design, but the system would still ultimately perform better if the CPU VRM were redesigned. Non Mac systems with the similar CPUs don’t have this issue and get better sustained performance.

  3. I’m new here, in need of desperate help... so so i have a MacBook 2010 13in. I installed an ssd a few months ago which is my main OS. My MacBook contains the original hard drive as extra storage space. recently i upgraded to Sierra 10.4 i believe it is from 10.3 and my original hard drive became unreadable.. so i followed the instructions on this link now my computer won’t startup and only shows the circle with the slash. I’ve tried disk utility to see if the disk needed to be repaired after tinkering with the library and extensions folders through the terminal but i really don’t know what I’m doing nor have much money to take it to a repair shop. I’m pretty good at following instructions(i thought) so just tell me what to do =\ and for some reason it won’t let me post i the original thread
  4. Hi, I've been dealing with this issue for a while now. In January I talked to Apple and kinda fixed it, but sometimes the issue comes back. I recently had to switch to a new router cause mine stopped working and now my MBP seems to be dropping signal, takes a long time to load and when it seems to catch the signal the website that I am trying to load, loads instantly, so I know it's not an internet issue, more of my computer connecting and receiving/dealing with information from the router. All this happens without losing connection to my router, the wifi icon on my MBP never gets greyed out, and according to iStat Menus, Airport is receiving/sending data. My other devices are not presenting this problem, they connect to the internet and I am able to load websites and such. Here's what I've already tried: *Reset router to factory settings / Changed SSID name and password / Channel set to AUTO * Done side by side connection speed tests of my MBP and the Windows laptop. Windows speed: 2.50MB/s - Macbook Pro: 1.75 MB/s *Changed my network settings accordingly with suggested settings I've found in this article. Any suggestions on this topic will be greatly appreaciated. I am a freelance designer and work from home so having reliable connection to the internet is a must for me.

    Hacking a Real Mac

    Completely new to this site and all the tools here. Had no idea you could even customize hardware like this. I love what you all are doing and look forward to learning more about hardware and the OS X underbelly. Seems that someone or something has used these tools to patch the hell out of my Macbook Pro laptop though, and it's taken me months to figure out that it's not malware or a rootkit but just apps and patches that all point either here or Tony86 or whatever his name is. I've even been through 5 AppleCare senior tech support people who couldn't figure it out... most of them dismissed the ordeal as paranoia since everything actually works so seamlessly which is a huge compliment to this whole project. I won't go into specific details here, but I'm hoping for any pointers since I'm sure I'm not the first one to have dealt with this. I was surprised there wasn't a sticky or any recent posts about this kind of thing, though, unless I missed it. From what I can tell, though, I've got Clover and/or Chameleon, and a whole bunch of kext and firmware patches, and I'm running Yosemite on a MacBook Pro 10,2 2013 Retina 13". If I just download and run something like MacPois0n will that allow me to see what's been done and fix it all? I just want to make it all go away! Thanks and I appreciate any helpful advice!

    15" Macbook Pro

    Hey guys, I am selling my 15" macbook pro. It has some small dents on the bottom of the casing, but none on top. Asking $1000 OBO. Feel free to make an offer on it. Core i7 2.66ghz 8gig ram 256gig SSD drive 15" screen hi-res 1680x1050 Bluetooth, iSight, Wireless Mountain Lion Microsoft Office 2011 Paypal and shipping included in price.
  7. I have had a hackintosh rig for about 2 years now. I currently run mountain lion on my desktop but recently bought a macbook pro of similar specs in hopes of having a portable version of my desktop. I have had clones of my drives on an external where in the past I could just plug into any normal apple computer and boot from the external and basically run an exact copy of my desktop on any apple computer with no issues. That was when I was using snow leopard and I never had any issues doing it that way until the newer apple hardware became incompatible with snow leopard. Fast forward to now I attempted to do the same thing but with a clone of my mountain lion set up on this mid 2012 macbook pro which also runs mountain lion. It loads up, apple symbol comes up and then it just gets stuck. I deleted all the extra kexts that would normally not be found on normal apple hardware and still it just does not load. What could be the issue? I cant be the only person to ever attempt running a clone of their hackintosh on a normal mac. I tried putting the clone on a partition on this macbooks internal drive and deleting the extra folder and extra extensions and keep getting the same results. Im trying to avoid using migration assistant since that is a simple solution that will cause headaches with programs I use and things that I do. I need an exact copy of my current rig on this computer. So please refrain from asking me why I don't just use migration assistant. I just need to know what I need to delete in order to run a clone of my hackintosh on normal apple hardware. I apologize for typing so much I just wanted to give as much background info as possible. Could it be something related to the EFI partition on the hackintosh clone?
  8. Hello Guys, im looking for the way of upgrade my MacBook Pro 2013 Retina SSD capacity. I only have 250GB and i need at least 500GB. I know that there are posibilites to use a "normal" PCie SSD M.2 with an adapter . My Model is Apple MacBook Pro 10,2 . (13" Core i5 Early 2013) (A1425) http://www.everymac.com/systems/apple/macbook_pro/specs/macbook-pro-core-i5-2.6-13-early-2013-retina-display-specs.html My actual SSD is an APPLE SSD SD256E What adapter di you think that will fit?? Im from spain. Thanks you so much! --------EDIT--------- This seems to also "works" https://www.amazon.es/BQLZR-mSATA-MacBook-Retina-adaptador/dp/B010SRKMRK/ref=sr_1_1?s=computers&ie=UTF8&qid=1497618448&sr=1-1&keywords=A1425+ssd but this converts a MSata SSD , not a M.2 SSD. If i understand correctly, a MSata disk is based in Sata III technology, and the M.2 that i should use for my mac book , needs to be PCie based no? so, how could it works in my mac??
  9. Hi, I brought a new HDD for my Macbook Pro . and connected to the system . it started showing me a flashing folder with question mark error. Then I figured out that the HDD is not being detected. I Connected it to a windows machine and converted it to GPT format and set the partition active in the command prompt. Again I connected it to my laptop and now HDD was detected. but it says "MISSING OPERATING SYSTEM" I tried all the combination keys like Cmd+R, Cmd+Option+R etc but nothing works. I am able to get the drive option when I press option at the start and when I select it, again the same msg in the black screen "MISSING OPERATING SYSTEM" I am not able to get the Internet recovery or the Globe for internet download. Old HDD has been formatted and no files .. :-(
  10. I got hold of an old 2009 Unibody 13-inch Pro, the 2.26 model. It's in great shape but doesn't power on properly. My guess is that it's the logic board, but being as expensive of a part as that is (and me being a broke-a** college student), I wanted to confirm the root of my issue before I plunge and make sure there isn't a more... economic fix. Here's the exact symptoms... - Unit responds when pressing power button as normal. Power light comes on solid and fans whirr into action, but it never goes further than that. No image or power to the display whatsoever. - hangs for a few seconds then abruptly powers back off again, making the hard drive clunk painfully. - Unit then powers BACK ON again and repeats the first part, but hangs indefinitely and does not power off again. Fan gradually begins to spin faster and faster. - during this whole time, the hard drive makes no read/write sounds whatsoever. It does spin up though. - I inserted a CD into the drive and it took, and now every time I power on it sounds like it's being read. Probably just the drive's firmware instincts though. - Unit does not respond to any keyboard commands such as target disk mode, etc, however I CAN reset both the PRAM and the SMC. Here's a link to a video of the cycle: http://www.youtube.com/watch?v=ZENwMamfsng Any insight is much appreciated. Cheers. EDIT: forgot to mention things I've tried... - unassembled entire unit and dusted/cleaned the {censored} out of it, incl. under heat sink - reseated RAM & all cable connections - other sticks of RAM - different HDD - ext. display
