Somez Posted February 8, 2017 Share Posted February 8, 2017 Very smooth on my T420 384mb HD3000 w/ Sierra atleast up until 1080p, but it gets choppy on the "superscaled" HiDPI resolutions accessible with RDM, SwitchResX etc. El Cap in general ran a bit smoother than Sierra though. Forgot to mention that I use the built-in LCD with it's native resolution (1600x900). Link to comment Share on other sites More sharing options...
jakibaki Posted February 9, 2017 Share Posted February 9, 2017 I can confirm that the new 10.12.4 beta 2 installs without problems (at least on the t420s). The backlight still doesn't want to work correctly (remove IntelBacklight.kext to get it somewhat working) Nightshift has to be repatched in the same way I mentioned before (don't just use your old patched binary, they made some changes to it so use the new one).

tluck Posted February 9, 2017 Share Posted February 9, 2017 yeah same here. i am using an app called "Brightness". the sys-pref slider doesn't work with IntelBacklight. but this app does - with IntelBackLight.kext. Link to comment Share on other sites More sharing options...
Somez Posted February 10, 2017 Share Posted February 10, 2017 So guys, do you think getting constant 0,65 GHz for the integrated GPU is normal? See attachment. Link to comment Share on other sites More sharing options...
tluck Posted February 10, 2017 Share Posted February 10, 2017 out of curiosity, i ran this tool in macOS and windows 10 - I got the same 0.65 flatline both cases. so seems normal? Link to comment Share on other sites More sharing options...

I'm thinking of filming the animations on both of our computers and post it here for comparison Link to comment Share on other sites More sharing options...
tluck Posted February 10, 2017 Share Posted February 10, 2017 i am curious also, what Finder animations are you referring to? Link to comment Share on other sites More sharing options...
Somez Posted February 10, 2017 Share Posted February 10, 2017 i am curious also, what Finder animations are you referring to? Exposé when showing all open windows and also I have the downloads folder in the dock (bottom-right corner) that pops-up. It's set to the so-called "fan" display mode.

tluck Posted February 10, 2017 Share Posted February 10, 2017 hmm. my Finder Downloads Fan (or Grid) display and Mission Control (expose) seems very similar to my T460 ... Link to comment Share on other sites More sharing options...
Fibroga Posted February 12, 2017 Share Posted February 12, 2017 Just sold my lenovo t420 and bought the 1600x900 version..i have the old usb of sierra. can i use it and after that, change the display thing?p.s. how to install modded BIOS? i have 1.49 1 Link to comment Share on other sites More sharing options...
tluck Posted February 12, 2017 Share Posted February 12, 2017 @fibroga - just change the config on the USB installer to match the display resolution. - if you have BIOS higher than 1.46, search this thread for the DMG/ISO image to create a bootable CD downgrade to 1.46. 1 Link to comment Share on other sites More sharing options...
Fibroga Posted February 12, 2017 Share Posted February 12, 2017 https://www.youtube.com/watch?v=fR208f0QKuQ Can i use this to downgrade from 1.49 to 1.46 mod? Link to comment Share on other sites More sharing options...

I did the same earlier, see this post for details. The concept is that winflash will detect if your BIOS version is higher than the one you're trying to flash and will not let you. But with that special command you can ignore that and it will flash the BIOS regardless to it's version. Good luck and let us know how it went!

gpspl Posted February 17, 2017 Share Posted February 17, 2017 As from 10.12.4 we can't control backlight with keys, we can either remove intelbacklight.kext or install brightness app, but neither of those solutions are any good , so maybe you can you look at AppleBacklightInjector.kext?

cammykool Posted February 21, 2017 Share Posted February 21, 2017 Here is the card I have in my t520-works OOB for me: https://www.amazon.com/gp/product/B009HN63QQ/ref=as_li_qf_sp_asin_il_tl?ie=UTF8&camp=1789&creative=9325&creativeASIN=B009HN63QQ&linkCode=as2&tag=mcdotechserv-20 ------------- What is the synopsis for 10.12.4? is it safe to do as of now? I saw the user above me note that backlight keys done work Link to comment Share on other sites More sharing options...
tluck Posted February 21, 2017 Share Posted February 21, 2017 i am using 10.12.4 beta 2 3 and currently IntelBacklight.kext does not communicate with the SysPrefs display slider or keyboard method. so for now: 1) remove IntelBacklight 2) keep IntelBacklight and use Brightness app. Link to comment Share on other sites More sharing options...
downlord Posted February 21, 2017 Share Posted February 21, 2017 With the last Chameleon 3994 I've got sometimes the error: Bad CMOS Checksum, at boot and some video glitches on external monitor via DP. Anyone else? All the rest is running smooth and stable. Good work. Link to comment Share on other sites More sharing options...

No smooth transition but you have full range and keyboard shortcut Link to comment Share on other sites More sharing options...
cammykool Posted February 21, 2017 Share Posted February 21, 2017 I do want to push my gratitude to you man. my T520 runs better running macOS then it ever did running Windows! has been stable as a rock on 10.12.3 and I used it back when you had the same guide for 10.11.5 but back then I was having lots of random KP issues i am using 10.12.4 beta 2 3 and currently IntelBacklight.kext does not communicate with the SysPrefs display slider or keyboard method. so for now: 1) remove IntelBacklight 2) keep IntelBacklight and use Brightness app. Link to comment Share on other sites More sharing options...
tluck Posted February 22, 2017 Share Posted February 22, 2017 @gpspl - perhaps you can share these kexts and dsdt patches @cammykool - you are welcome. glad things have stabilized for you! @downlord - cmos reset on occasion? what bios level are you ... hmm. wonder about the HW failing? what kind of video glitches on external monitor. i have switched my EDID (and display overrides) to be RGB mode only to eliminate odd colored menu items.

gpspl Posted February 22, 2017 Share Posted February 22, 2017 @ tluck - I can't simply share kext as you have to generate applebacklightinjector.kext for your lcd panel. All is in rehabman post - https://www.tonymacx86.com/threads/native-brightness-working-without-blinkscreen-using-patched-applebacklight-kext.121031/ Use v2 patcher to generate injector. Patch DSDT with "13" patch from his repo. Link to comment Share on other sites More sharing options...
