scoobaspeaz Posted March 4, 2016 Share Posted March 4, 2016 Scoobaspeaz, maybe installing a virtual Os X with VirtualBox? I didnt think OS X would virtualize in VirtualBox. If so how do you get the ISO cause apple requires getting it from the Mac App store and be running OS X already? If its possible to virtualize it, and I can get an ISO, i would try that.

nhoc_maruko9x Posted March 4, 2016 Share Posted March 4, 2016 I'm running El Capitan, my T420s recognizes USB 3.0 port only if I plug the usb before the laptop booted up. Also if the usb is still plugged in, laptop can't be shutdown. Any idea how to fix that? I remember there's no problem with Yosemite. 1 Link to comment Share on other sites More sharing options...
parcox Posted March 4, 2016 Share Posted March 4, 2016 @parcox - i recently went through this same procedure. so when you change your screen to 1600x900 it is very important that your change the cable with new inverter too. the inverter is specific to the screen size. Yes, I'm aware of that. In fact I already bought the inverter but the screen is not yet. parcox, to update to a 1600x900 it´s unbelievable in usability. I had first a 1.366 x 768 one, and when a I moved to a 1600x900 i really got impressed. That's good information for me, some people said that 1600x900 on 14 inch is not really good for text reading such as web browsing etc. Would you confirm that, or maybe you could attach some screenshot of your screen while browsing or using word processor application.

tluck Posted March 4, 2016 Share Posted March 4, 2016 @parcox - glad you knew about that. thats a detail that could get overlooked! good news is you can always use a lower res 1368x768 1600x900 @nhoc_maruko9x - its my understanding that the USB3 on the T420s is not Intel or Fresno Logic based chipset - so i don't know of a good solution on El Capitan. @scoobaspeaz - using a real mac or hack to download and create the USB is the easiest way for sure. do you know anyone with a mac? Otherwise, the virtual machine route may be the best way. About 4 years ago i created a snow leopard VM from a $29 DVD i bought from the apple store! now the OS is free but harder to get. 1 Link to comment Share on other sites More sharing options...

But it all depends on your vision. Like my company provided 14" Dell is FullHD and I'm not comfortable with that resolution. Link to comment Share on other sites More sharing options...

gpspl Posted March 4, 2016 Share Posted March 4, 2016 How to fix blinking led after wake (led flashes like t420 is still sleeping). It's DSDT fix but where? Link to comment Share on other sites More sharing options...
tluck Posted March 4, 2016 Share Posted March 4, 2016 @gpspl - is this on a T420? are you using the DSDT from the zip? if so there is logic in the _WAK Device to set the LED depending on sleep mode. Link to comment Share on other sites More sharing options...

vusun123 Posted March 6, 2016 Share Posted March 6, 2016 @tluck thank you working on my fhd t420s is perfect but USB 3.0 There's a method to make it work on 10.11 on the "dark side of the hackintosh community", google it and hopefully it will fix your problem 1 Link to comment Share on other sites More sharing options...
tluck Posted March 6, 2016 Share Posted March 6, 2016 @oxygen427 and T420s owners. thinking about the USB3 issue some more, I recall reading that some have replaced/rolled back the El Capitan USB kexts with Yosemite kexts. perhaps that is the method that could get all the USB ports working for you and others. 1 Link to comment Share on other sites More sharing options...
Zeridialous Posted March 6, 2016 Share Posted March 6, 2016 I took a quick look through the thread but I didnt see anything, is it possible to get Clover to display at the native 1366x768 resolution? Im trying to get the boot screen to display and transition as smoothly as possible, however right now it's displayed stretched and then switches to the correct resolution but I lose the Apple logo when that happens. Any ideas? thanks Link to comment Share on other sites More sharing options...
Zeridialous Posted March 6, 2016 Share Posted March 6, 2016 For those of you who find the T420's speakers to be quiet and muddy sounding I wanted to share this -- there's an app called Boom 2 that lets you boost the volume and apply a system wide equalizer, Ive been messing around with the settings and with the settings in the below screenshot it seems to have definitely helped. EDIT: Helps if I attach the screenshot... *facepalm* Link to comment Share on other sites More sharing options...

Any ideas? thanks not that i know of. there are only a view resolution options for the BIOS (or Clover) to use - they seem to be 4:3 or 16:10 ratios. so i chose the resolution closest match with least distortion given the 16:9 ratio - 900x600 0:593 0:026 SetScreenResolution: 960x600 - setting Mode 1 0:699 0:105 Video mode change to mode #1: Success 0:699 0:000 Console modes reported: 7, available modes: 0:699 0:000 Mode 1: 80x25 0:699 0:000 Mode 3: 96x25 0:699 0:000 Mode 4: 120x31 (current mode) 0:699 0:000 Mode 5: 128x40 0:699 0:000 Mode 6: 80x25 0:699 0:000 Mode 7: 100x31 5:351 0:000 CurrentMode: Width=960 Height=600 Mode X Y ratio: 1 640 480 4:3 3 768 480 16:10 4 960 600 16:10 5 1024 768 4:3 6 640 480 4:3 7 800 600 4:3 check this site for a clover patch to fix the 2nd stage boot logo glitch. https://github.com/RehabMan/OS-X-Clover-Laptop-Config/blob/master/config_HD3000_1366x768.plist <dict> <key>Comment</key> <string>Boot graphics glitch, 10.10.x/10.11.x (credit lisai9093, cecekpawon)</string> <key>Disabled</key> <true/> <key>Find</key> <data>AQAAdRc=</data> <key>Name</key> <string>IOGraphicsFamily</string> <key>Replace</key> <data>AQAA6xc=</data> </dict> 1 Link to comment Share on other sites More sharing options...

tluck Posted March 6, 2016 Share Posted March 6, 2016 no should not be needed. you can define the buffers set by the using this id or by the model. with the MBP8,1 model we typically use i am pretty sure, we are using the 1st frame buffer set.

I was careful in boosting the audio and lowered the bass with the equalizer to minimize any amount of distortion, so far so good. Link to comment Share on other sites More sharing options...
tluck Posted March 8, 2016 Share Posted March 8, 2016 has any tested out the 10.11.4 beta versions ? it has been a complete disaster for me - getting tons of graphics artifacts and the dreaded "possible hang in main graphics engine - which freezes up the screen way too often.

Nop. I remained in Yosemite. Even in my Mac Pro. "Upgrading" to El Capitan has no sense to me. tluck, waiting for my X220 , i have this guide. http://x220.mcdonnelltech.com/os-x-yosemite-installation/ but implies using [url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url], Theres also one for El Capitan, seems mo up to date, that i don´t want to install…. http://x220.mcdonnelltech.com Do you have any idea if could simplify the method for install Yosemite, more similar to yours in T420? Thanks a lot in advance. Link to comment Share on other sites More sharing options...
tluck Posted March 8, 2016 Share Posted March 8, 2016 trifero - i don't understand your question - this guide applies to Yosemite or El Capitan installation with Clover on the T420 (or X220). Link to comment Share on other sites More sharing options...
trifero Posted March 8, 2016 Share Posted March 8, 2016 Ok, sorry. Forget it. Thanks anyway. Link to comment Share on other sites More sharing options...
tluck Posted March 9, 2016 Share Posted March 9, 2016 well it seems that mcdonnelltech leveraged the same files from this guide - DSDT and kext pack - so its pretty much the same thing as here. if you already have a disk with OSX - you could just clone it to the drive on your X220 - then all you do is add the ESP and custom kexts.
