    Lenovo ThinkPad T420 with UEFI Only

    Re-make your win7 installation using Rufus. Select gpt for uefi computers when making it. Make sure your Iso is 64bit. And you may have issues if the image is x86 x64 multi

    Thinkpad T430 - Mavericks 10.9.x - Yosemite 10.10

    You are right in that the bios id's are different. T430s is G1ETA1WW at 2.61 while T430 is G7ETA1WW at 2.61. But on closer inspection, you'll notice that they sometimes skip version numbers between releases. This indicates that they use the same base and merge in before a release build. For any number of reasons the T430s has fallen behind where previously they were even. Likely due to the T430 base being more popular among enterprise clients, so it gets more updates. The NVS that most of the T430s's ship with adds complexity to that system which may contribute to its falling behind. But you'll see a version skip eventually and the T430s should catch up or remain close behind. It has to, having all those versions would be a nightmare to have for each sub-variant. If ever the T430s falls too far behind, you'll see lenovo stop supporting it altogether.

    T430 and T430s use the same firmware. You should run latest if you don't have a mod.

    @juxtaposse I know nearly 1,400 posts can be daunting to read, but your answers are in there. Tluck's best answer at the top has been refined and revised over its life here in this thread. Most recently tluck's re-tooled it with user-friendliness in mind. If you read it thoroughly and are able to comprehend it, you will be successful on your T420. That said, Tluck's guide does allow for nvidia graphics to be used, however, the method is new. The full details of it are scattered within the last few pages. The information has not yet been compiled into Tluck's guide. There is a blurb in there about drop table MCFG, but I recommend you understand it before you go enabling it. T420 and T420s are not the same. Extremely similar, yes, but not the same. To answer your second question directly indirectly, there is a compatible Dell card in this thread. Taking your bottom access cover off will answer your question 2b. Officially, this thread supports the combination of the T420 and Clover boot loader and OSX. We help from time to time with T420 variants and even the T430 and even more rarely answer a question or two about Chamaeleon. But please keep in mind that the active members mostly have the base T420. Myself, I have a T430 (which my wife uses as a DD and I can hardly ever get to touch anymore). Shortly, my comments will be flagged as unhelpful, but my intent is that you may be able to answer your own question more quickly by just reading or searching the thread than re-asking a question. Honestly just trying to help. :\

    It depends on the antenna config. 1x3 should reach 450 but sometimes they cheap out and make it so that its 2 down and one up but 2x3 should reach 900 unless its 3 up and 3 down then its only 450

    Its true that wireless n is maxed at 150 per channel but a 2.4ghz card is only one band. Dual band uses 2.4 and 5 simultaneously hence the dual band. If you are using 1x2 or 1x3 you can get 300 or 450 all the way to 900 but now its unnecessary as ac can top that. So no, windows is not over reporting.

    If it keeps going back to the boot selection menu aka the f12 menu, then it's not finding bootx64.efi Your partitions on the USB could be wrong or your clover installation could be wrong/missing. Try following the guide again, carefully. If it still fails, post your partition info and verify that /efi/clover exists and has files.

    To the comments about w8 enforcing its boot loader: W8 does not do this. What you are seeing is called hybrid shutdown, the default shutdown behavior of w8. It logs out all users, effectively terminates all non system processes or anything that depends on user interaction, and then hibernates what's left of the system. This is how M$ got it to shutdown and boot so quickly. It never truly shuts down the system unless an installer or a system update explicitly calls the full shutdown. Luckily the user can also call a full shutdown, but more on that in a second. You can verify this if you try to access this partition from another is. Let's use Ubuntu for example. After you perform a 'normal' shutdown and then swap the hard drive into an enclosure and try to access it from your Linux box, it won't mount. It's a regular NTFS partition but gparted will tell you that the partition is hybernated and won't allow you to make changes to it. This is also why it won't mount. However, if you perform a 'full' shutdown, the partition is normally accessible. That was just part of hybrid shutdown. The other thing it does during a hybrid shutdown is that it sets the next_boot flag in nvram (uefi persistent memory). This forces the system to boot the hybernated partition exclusively so as to not give you an opportunity to 'accidentally' muck up your windows installation. It's a (safety) feature, if you will. It's side effect is that following any 'normal' shutdown, the system will always boot to w8. But a full shutdown won't set this variable and the system is free to boot normally. So it may appear as if windows is 'setting itself as primary' , but in truth, it does no such thing and in fact, 'primary' has no meaning in an uefi system. The only thing a uefi system does is look for the efi partition and boot whatever is inside of it, always. Failing that, it looks for a fat32 formatted partition with bootfiles. To conform to the efi spec, OS's need to install their loaders (or parts of) in the efi partition under their own folders, respecting the presence of other (foreign) boot loaders And not interfering with them. Clover is installed in its own folder within the efi partition and uefi is told to boot it by default, but you still have an opportunity to boot anything else if you so choose. Though all of this is bypassed if boot_next is set. So how to perform a full shutdown? Run: shutdown -s -t 0 That's it. Make it a link on your desktop for easy access. Though your next boot will take longer, though on an ssd the difference is unnoticeable. There is also a permanent way to disable hybrid shutdown, but I don't remember it off hand as the shortcut is quick and painless for me and I rather like hybrid shutdown when I know I won't be switching systems.

    Getting discrete graphics to work has been a sticking point for us for some time. Part of the reason is that the HD3000 works well enough alone.Take a stroll through the 430 thread. There was a user there once that had limited success. See if your needs can rekindle our drive.http://www.insanelymac.com/forum/topic/293762-thinkpad-t430-mavericks-109x/?view=getnewpost

    You are limited to only 2 of the available 4 buffers. You may use any combination of them but you may never exceed 2 active displays. It's a documented limitation of the chipset. (Sorry, can't remember the source). You can get around this by using a usb display adapter, but your mileage will vary. I used some really crappy startech adapters and the display attached to it was always jittery. Couldn't watch videos let alone play games. Also, most usb display adapters don't actually have any kind of processor in them. They steal cpu cycles and that's about it.

    @adrenalation Catch up with some of the latest pages in the thread, like the last 4-6. Tluck made changes to his pack so that we'd only need to use the one config.

    Ah ha, Quite persuasive. I concur. However, the OP for the 420 thread is hard to contact. He has not been active for quite some time. As 430 questions pop up, I will direct them here. Currently there is at least one user that needs to enable discrete graphics and has thus far been unsuccessful. Perhaps you could jump in temporarily over to the 420 thread for some advice? I have a 2349GCU so no discrete graphics I'm afraid.

    @simon Since you're using a separate disk for W7, you are better off reinstalling 7 and formatting its disk as mbr. Clover will see it just fine so long as clover is installed on OSX's disk and that disk is set to boot first. W7 gains no benefit to being installed on gpt nor booting in efi mode. (besides greater complexity[headache]) Please visit a few pages ago, where we discussed this in greater detail. EDIT: Ah, Tluck beat me to it. He's right that it is a simple process, however, since you do not have a specific need for w7 to boot in efi mode nor on a gpt formatted disk, then I believe it is indeed easier to proceed as mbr. (but only because it's on a separate disk)

    To alleviate some confusion, most of your post install issues have been discussed over here in the 420 thread: http://www.insanelymac.com/forum/topic/285678-lenovo-thinkpad-t420-with-uefi-only/page-25?do=findComment&comment=1952283 This link also drops you right on tluck's 420 guide which is a good jumping off point for those of you still having trouble installing. The thread was meant to be renamed to include the 430 but I never provided the OP with my files. It seems that Uoc Nguyen and eliatuno have a good packs. Please feel free to head over there and continue the discussion. I'd hate to see fellow 430 owners struggle and redo research when there's a parallel thread. Thanks for your work so far.

    @Tetonne You don't need to erase disk0s2. You now need to run your 8.1 install usb again and run repair mode. You will need to use bcdedit to restore the windows 8 bootloader and bcd info. Verify that windows 8 boots. (OSX will be inaccessible temporarily). Then boot from your OSX install USB and reinstall clover to the ESP. Then Clover will become your bootloader for both operating systems. This is precisely why i recommend installing OSX first, as it's easier (IMO) to install windows without having to mess with it. Windows relies on the ESP, its boot files are placed there during installation. OSX doesn't actually use ESP at all. It's only there to meet the spec.

    @honeywell I was assuming that you would be using GPT. To support tluck, there's no real good reason to use MBR. Windows 7 will boot on a GPT disk provided you use a bootloader like Clover or swap in the Windows 8 loader. In your particular situation, you should install Mac first to ensure that your disk is already formatted. Windows 7 will try to format the disk to MBR by default if no operating system is detected. If the disk is already partitioned when Windows 7 setup runs, it will try to use it as is. If you absolutely can't do it this way, you can try to install windows 7 first, but the process is much more involved. You would have to install W7 and then convert your disk to GPT (which is possible, I did this before using a script I found, I'll find it if you're interested.), then install W8 loader or Clover, then install mac. Or option D give up on W7 and install it in a vm. PS when you use rufus, make sure you select gpt partition scheme for uefi systems that way you can make sure that the system boots in uefi mode and not legacy. W7 setup will detect this. You didn't post any details of your setup when you got the error, so I'm trying to cover all the bases.

    @all To simplify making uefi bootable dvd's, use Rufus. http://rufus.akeo.ie/ The windows 7 dvd is not natively uefi bootable (rather, most images of it are not). Rufus can take any windows 7 install iso and turn it into a uefi bootable usb or dvd. It does much more, but this functionality is all you need for this example. The rest of the process is still the same, but I remember a time when I spent many hours trying to uefi boot my windows 7 disk. also your 420's run 8.1 blazingly, please consider the upgrade. Everyone whines about 8, but 8.1.1 has reintroduced most of the features that will satisfy windows 7 users. you even get title bars on your full screen tile apps now. You can kill them without having to resort to task manager.

    @tluck Once again sir, you are correct. OSX is capable of sending TRIM commands, but apple restricts the capability to only Apple SSD's in IOAHCIBlockStorage. Apparently, you can just replace "Apple SSD" with "INTEL SSD" or whatever the first 9 characters of your SSD's id and it works just fine. Why Apple, why?

    Lenovo ThinkPad T420 with UEFI Only

    @parcox If you did clone to SSD, bear in mind that cloning to SSD is not recommended. Clean install is the way to go. @tluck Is enabling TRIM with a kext patch still necessary? TRIM should work natively with 10.9.x At least, it should if the disk was detected correctly during install.

    @k.surachai Did you change the codec id to match your codec? I don't have an X-series, but it may use a different codec than the T series. @tluck Thanks for the attempt, but that thread is dead. Not a huge fan of necroposting. Which brings me to why I want to learn how to do it. Apparently, there aren't enough firmware modders out there.

    Anyone know of a good resource on how to perform the EFI whitelist mod. I know you guys have a 420 firmware that's already whitelisted, but I can't find one for my 430. EDIT: I believe I found one some time ago, but the version was old. I want to know how to perform it myself. Because Lenovo still updates the 430 firmware. EDIT2: And I can't rollback anyways as I have the newest firmware.

    @tluck et. al. I don't remember if this was brought up before or not, but on the 420 and the 430, we have display limitations. the HD3000 only physically supports 2 displays. Likewise, the HD4000 in my 430 only physically supports 3 displays. Something with the display bus limits physical connections on mine to also 2 devices, but it's not aproblem. It was documented somewhere that the 430 only supports 2 displays. I'll post the link if I find it. What I was wondering, is how the expansion port comes into play here. I already have 3 outputs on the unit (as do you): VGA, mini-DP, and LCD. Only any 2 of those 3 will work. Now when the unit is docked, I have an additional 3 outputs available (DP, VGA, DVI). (Or if you get the big dock, you get 5 ports: 2x DP, 2x DVI, VGA) I can verify that you may use any 2 of the total 6 ports in any combination. This includes unit ports and dock ports simultaneously. So does the expansion port have a physical pass-through for the display bus? All the display ports are physically wired to the same DVI/DP bus. The VGA is actually D-SUB. How does clover handle this? Is it contributing to the display issues some of the users are having? The only way I've ever been able to utilize 3+ monitors was to buy these lousy USB-w/e adapters from Startech. They suck, don't use them. Your GPU is not driving them. The software creates a new virtual display per each adapter you have hooked up. The more you have, the more your poor CPU gets bogged down. This causes all of the monitors connected through those adapters to have really laggy response times/stuttering. But the physically connected displays are still fine.

    I've done that to my monitor before. I have an Acer 19" LCD from like 5 years ago. It only has a vga port, but its EDID Allows it to pnp and Windows hot detects it just fine. But one day, out of the blue it stopped working. After a reboot or two, it came back on, But windows was calling it a non-pnp monitor. I said 'that's odd...' Up until then it was always detected by name and its driver loaded and everything. But that day it just showed non-pnp monitor. Then I noticed that a whole bunch of new resolutions and refresh rates opened up. And I thought, well awesome, let's see if we can't tweak these. So stupidly, instead of realizing that Windows could not correctly communicate with the monitor (so it couldn't probe for valid res+rr) I set about picking combinations that i'd never used before. Some of them made the screen go rainbow.. some of them made the rainbow kind of twinkle like tripping on acid... some cut off a portion of the image, and the auto-adjuster couldn't fix it ... the last one i tried made the screen go completely black. At no point did I see an OSD message about an invalid resolution. My Gateway 21" on the other hand let's you know when you screwed something up. So I slowly wept when the monitor didn't come back on after the 15 sec confirmation reset. The light remained amber and I though I had blown it up. But lo, when I rebooted, it came back on, and cried some more. (So pathetic to get attached to your toys. But you tend to appreciate them more when every piece of equipment you have is a hand me down or a garbage pick or an inheritance from work you do on other's computers.) So after all of that, while doing doing some cable management a few days later, I found that one of my 2 dip{censored}, butthole, {censored} cats had chewed (almost) through several cables, including, to my surprise, my vga cable. I examined it thoroughly and found that some of the wires were exposed and possibly shorting. I was amazed because the jacket on this cable was really thick. Even thicker, some of my AC cables had deep punctures in them. I almost wish they'd have been a little deeper... Anyways, I replaced the vga cable, and the monitor started working properly again. It was detected correctly in Windows and I was once again restricted to only valid res+rr. Driver loaded and everything. </endstory>
