mackyreddy Posted June 29, 2013 Author Share Posted June 29, 2013 @ MBdip if you have working OS X or either OS X in Virtual Box, From your working OS X, open diskutility restore the pre installed OS X 10.8.4 to the USB drive and then install latest chameleon Bootloader on to the USB and you are ready to go. @ ananth Well the same applies to you as well just restore the image and make sure you have installed chameleon bootloader on to the USB drive.

Illuyer Posted June 29, 2013 Share Posted June 29, 2013 Well, I an having a bit of a problem. I had 10.7.2 installed perfectly fine, but after a few days of use, kept on getting a blank screen after boot up, so decided to go with a fresh install of 10.8.2 instead. Also decided to do it on my SSD (after partitioning it, of course alongside my Win 7).Set up the install USB on a virtual box, and successfully went through the install process. The problem I am having is though, that MacDrive won't see the drive, no matter what I've tried. I've tried to reinstall about 3 times with the same outcome, and even tried to do it on my HDD instead of SSD to no avail. Any help would be greatly appreciated. Cheers. Anyone?

mackyreddy Posted June 30, 2013 Author Share Posted June 30, 2013 Download 2.2svn-r2252-i386.zip from this link http://www.osx86.net/view/3856-chameleon-2.2svn-r2252.html After download extract it 1. Now open the folder i386 and copy boot1h to your Bootable USB drive. 2. Now boot from USB and go to utilities and open Terminal 3. type " diskutil list " to identify your disk and partition where you installed ML ( for example disk0s2 ) 4. type " diskutil unmount disk0s2 " 5. type " cd / " 6. type " dd if=boot1h of=/dev/disk0s2 bs=4096 " 7. reboot In step 6 put your disk and partition and also don't include " " i have just used them to highlight what to type in terminal.

Guest ananth Posted July 1, 2013 Share Posted July 1, 2013 @Mackyreddy i have been able to install iAtkos Ml2 l but at first boot i am getting an error. I have uploaded the screenshot of the error. Also i haven't modded my A19 bios should i install a modded bios and is it safe??? Also what bios setting must i enable for successful installation of mac os?? Thanks in advance :-) Link to comment Share on other sites More sharing options...
mackyreddy Posted July 1, 2013 Author Share Posted July 1, 2013 Are you using A.19 custom bios created by Timewalker and captain Sarkar or stock bios from Dell ? If you are using Stock bios from dell ( that's what i can interpret from your pic) then you need to use nullcpupowermanagemet.kext in order to boot. But i will recommend & suggest you to install or upgrade to A.19 Custom bios, otherwise you are been forced to use either nullcpupowermanagemet.kext ( problems assisted with this kext is there is no proper cpu management and cpu tends to remain hot, no sleep and many other problems i cant remember) or Patched Appleintelcpupowermanagemt.kext ( which is no longer maintained as most of them have been migrated to A.19 Custom bios). Hope you got my point. Update Aah haven't read your question completely, well as i said i would recommend to update to A.19 custom bios but make sure you plugin power adapter and it should be safe to update as we all have updated long back and i dont see any problems after update, just make sure you take precaution while updating like disable UAC on Windows and run the update with administrative privileges. Also make sure you have an optimus laptop as the update is meant for optimus laptop not for 3D. Link to comment Share on other sites More sharing options...
Guest ananth Posted July 1, 2013 Share Posted July 1, 2013 I was able to fix that issue by using nullpowermanagement kext....i will upgrade to the modded bios soon..... After using the nullpowermanagement kext the first boot seems to get stuck...i used -v -x. It is getting stuck at a point. i was able to take a screenshot Link to comment Share on other sites More sharing options...
webcivilian Posted July 1, 2013 Share Posted July 1, 2013 @anath - If you are not going to install the custom A19 bois then you will have to use NULLCPU kext as the MSR are locked and you are using only 1 core out the 4 logical and 8 with Hyper threading. The only way to get full CPU is either through the custom A19 bios or AppleIntelCPUPowerManagement kext modified for your setup. I recommend the custom bios as you can revert to the original bois any time. It is even included with the custom bios zip file. Link to comment Share on other sites More sharing options...

Zulakis Posted July 3, 2013 Share Posted July 3, 2013 Hi mackyreddy, I recently upgraded to 10.8.4. Sadly, the audio kexts in your 10.8 kext package don't work for me. Can you verify this? Does anyone have working L702X audio kexts for 10.8.4? Link to comment Share on other sites More sharing options...
webcivilian Posted July 3, 2013 Share Posted July 3, 2013 @ Zulakis - I made the audio kexts and they work just fine. Is there any error you get during boot. I would download the kext pack again as it was updated and use Kext Wizard to install the kexts. (AppleHDA and IOAudioFamily). Make sure you repair the permission and rebuild the kext cache. Also, I guess you need to use my DSDT (NVIDIA DSDT Off by webcivilian) from the Kext pack. Link to comment Share on other sites More sharing options...

webcivilian Posted July 3, 2013 Share Posted July 3, 2013 Can you try these kexts from http://www.insanelymac.com/forum/files/file/24-applehda-for-alc665/ Make sure you delete any VoodooHDA kexts from S/L/E. It could be the reason for the audio to not work. Attach your DSDT, AppleHDA and system logs from the current config. And you are using the kext and dsdt from this kext pack: XPS 17 10.8.x Kexts Pack V2.zip? Link to comment Share on other sites More sharing options...
Zulakis Posted July 3, 2013 Share Posted July 3, 2013 Yes, I used the Kexts Pack you linked. I just tried out VoodooHDA 2.8.4 and it worked out of the box. (Didn't have it installed before). Thanks for your help though :-) Link to comment Share on other sites More sharing options...

mackyreddy Posted July 5, 2013 Author Share Posted July 5, 2013 Hey Webcivilian, If you are free, please update A.19 Stock DSDT with the paches and tweaks which you applied for Nvidia Off DSDT. So that we can have consistent DSDT's. As folks like zulakis are having problems when they are changing DSDT's as AppleHDA Kexts have 88 layout id. For example stock A.19 DSDT uses ALC 665 layout id i guess and you seem to have changed it to 88 and many other tweaks which i don't know what you applied. I am currently busy dissecting Stock A.19 DSDT from scratch to find the memory consumption differences problem but still i am planning to update the kexts pack as there are quite few changes new updated kexts from Rehabman, Nvidia Off DSDT with Dual Link Patch, Common and consistent Extra Folder regardless of any DSDT, i mean new & consistent org.chameleon.boot.plist which will be common for both DSDT's, Also planning to add Pre installed Micro OS X 10.7.5 image ( Arguably the best & Optimized OS X version better than Mountain Lion 10.8.4 & Snow Leopard 10.6.8) and hopefully consistent Stock A.19 DSDT with same tweaks, patches and HDEF layout id from your side. So quite a few new updates are gonna come in the next kexts pack . regards Stock A.19 DSDT.dsl.zip Link to comment Share on other sites More sharing options...
webcivilian Posted July 5, 2013 Share Posted July 5, 2013 OK applied all my patches so it should work the same as NVIDIA off DSDT for the kext pack. I have updated the NVIDIA off DSDT with Dual link patch. But still requires device properties.

mackyreddy Posted July 5, 2013 Author Share Posted July 5, 2013 thanks for patching stock A.19 DSDT, dont worry about Nvidia off DSDT, i already patched it successfully. I will update the kexts pack ASAP. Update: Attached New Kext pack to the first post. Link to comment Share on other sites More sharing options...
