You should be Ok with Jake's usual Clover guide. Failing that, you may turn to my E6220 Enoch guide and follow the same process. You may use the E6320 DSDT instead of the E6220's. Make sure you've configured your BIOS according to the recommended settings. You can refer to this thread.

All details of AppleHDA patch available here for instance. Remember to copy the IDT 2HD93 dummy kext to /L/E, repair permissions and rebuild your cache.

Fan control may be in an annexe SSDT. Dump all your native ACPI tables to check this. Do you have native CPU SpeedStepping on this T7500? What graphics card do you use? You could start by posting your specs and zipped EFI/Clover folder if using Clover or zipped Extra folder if using Enoch... May be it's a simple matter of incorrect or untuned settings.

A few things to correct in your Config.plist: in ACPI section, remove P States & C States generation, that's for C2D, C2Q and 1st gen "i" Core (like Arrandale) CPUs. in Kernel & Kext Patches, remove KernelPm patch, that's for Haswell and later platforms; AsusAICPUPM is all you need for your SandyBridge platform (keep AppleRTC patch). In Kernel & Kext patches, what are all those AppleGraphicsDevice Policy patches? In Kernel & Kext patches, do you really need the USBXHCI patch? Do you intend to add USB hubs that would increase your USB ports beyond 15? In Kernel & Kext Patches, simply add the required 3 x AppleHDA patches: replace 8419D411 by 00000000 (2 x instances if you manually patch the kext) replace 8A19D411 by 00000000 (2 x instances if you manually patch the kext ) replace 8B19D411 by E7761D11 (2 x instances if you manually patch the kext) Then add the dummy kext for IDT92HD90 to /Library/Extensions, repair permissions and rebuild your cache. That'll give you full audio. sudo chmod -Rf 755 /L*/E* sudo chown -Rf 0:0 /L*/E* sudo touch -f /L*/E* sudo kextcache -Boot -U / For native CPU SpeedStep, you need to generate your CPU-specific power management SSDT though Pike R Alpha's well-known generator script.

Re: audio, you'll have that working if you follow the same process as for any Latitude E6x20 laptops. They have same IDT 92HD90 codec. But since you've not bothered to provide any details of your installation, we can't guess whether you'll need patched AppleHDA kext for Enoch or on-the-fly patches for Clover. Anyway, if you search the forum, you'll find what you need. Same for GPU, we don't know whether you use integrated HD3000 or discrete nVidia Quadro 4000M with Optimus disabled.

Fans not being detected at OS level is not necessarily an issue; BIOS is perfectly able to control fans according to CPU T° and other elements. This being said, are you using a recent FakeSMC and all its sensors PlugIns?

Not a known issue on the E6220. Can you give some examples?

Please refer to the FAQ section.

Bottom line is: can you connect to your wireless network now with my posted patched DSDT?

If LAN is en0, then you should be able to access AppStore. What message do you get?

Re: AppStore, check that your LAN card has registered as interface en0. In Terminal, type ifconfig to verify this. If it's not en0, delete all network cards from your Network PrefPane and all plist files from /Library/Preferences/SystemConfiguration. Reboot and check your Network PrefPane. If no interfaces are there, manually add the Ethernet. In Terminal, your LAN card should now be registered as en0.

Keep a backup of your previous DSDT somewhere and replace it with the following revised patched version (rename it to DSDT.aml or call it as DSDT_DW1502.aml in the boot loader). DSDT_DW1502.aml.zip Your IOReg shows your DW1502 card with id 168c,2b under device PXSX attached to device RP04@1C,3: In DSDT, we therefore look for that device RP04 at address 0x001C0003 (=1C,3): We find the device PXSX attached to it: Then we apply the published patch.1) we rename device PXSX to ARPT (common Apple wireless device name) and inject the _DSM method that declares compatibility with supported Atheros AR9380 chip 168c,30 (only the "compatible" statement is mandatory, rest is just cosmetic): 2) At compilation, an error message reports that there is a reference to an unknown device PXSX under HPME. We therefore rename this old reference to RP04.PXSX to ARPT: That's it, table now recompiles without error! Your DW1502 should now always work under any version of OS X that natively supports Atheros AR9380 chip.

Yup, Ivy Bridge i3 CPUs don't have Turbo boost at all and the i3-3110M runs @2.4GHz and that's it. So you can't disable something not available... To be honest, I never use that Turbo-disabler-on-battery kext. My laptops run at full performance capacity all the time.

Please post your DSDT + saved IORegistryExplorer output. Both zipped.

Maybe because it was compiled with another tool such as DSDTEditor or the file is corrupt.

BIOS upper limit for OS X should be around same version as for the E6230, i.e. A11. It could be A12 of course but I don't think you can go much higher... Do a Search on the forum on "E6330 BIOS" and see what you find... Failing that, best way to know is to try until your graphics go bad, then reverse to oldest possible version like A02 and upgrade again to the highest safe version. I'd bet money on A11.

No, you're missing the point totally. You won't be able to boot your installed system unless you copy the /Extra folder and the necessary kexts to your freshly made OS X installation. Reboot your USB installer, go to the main installer screen and run Terminal from Tools menu. Then copy the Extra folder from your USB key to your freshly made OS X volume/partition. diskutil list -> to identify the name of your freshly made OS X volume/partition cp -Rf /Extra /Volumes/<name of identified OS X partition> ` I can only advise you to read my Chameleon/Enoch-based Yosemite/ElCapitan/Sierra guides posted here to familiarise yourself with the actual installation process. Until you fully understand it, you will probably not succeed. This being said, you must have managed to copy something to be able to boot OS X. Maybe you're actually using distros... But if you've not copied the Extra folder, you're missing the DSDT so you'll have to manually set DualLink through Chameleon boot option EnableDualLink=Yes. You may add Injectntel-ig=00000100 but that's probably not necessary with HD3000. If in doubt, type "?" at Chameleon prompt and you'll see some help on the boot flags and options.

Cards based on AR9285 Atheros chip require either a patch of the Atheros40 kext or a simpler DSDT patch as published in the wireless card inventory thread. It's a simple matter of identifying your wireless device in IOReg through tools like IORegistryExplorer, then apply the patch to that device in DSDT. You can more or less copy/paste the published patch but all you need is the "compatible" statement.

Erm... did you copy/install the /Extra folder of your USB installer to your HDD partition? Seems to me that you did not...

If you did read the thread, you must have noticed you need a patch...

No need to activate "Drop SSDT" in the o.c.B.plist; it's not necessary. Same for "Enable DualLink", it's already set in the DSDT (see IGPU section). This being said, can't see why you'd still have graphics issues. But I do wonder how you boot your Yosemite USB installer, namely which Chameleon version are you using and how do you load kexts from /E/E, especially FakeSMC? Please note that the pack is a little outdated and that you should no longer require the patched AppleSDXC kext since a little DSDT patch suffice for the SD card reader. What's the LAN card on a E5420 by the way?

Are they both on the same BIOS A11? Which i3 CPU are we talking about here? Please post a zipped copy of your EFI/Clover folder.

The custom EDID you've injected does not match the 128bytes value extracted. That's a 1st problem. To begin with, leave that blank and just tick the "Inject EDID" box. If you still don't get the screen working, you may then add the correct 128bytes EDID.
