Your GPU is based on the nVidia 7300 chip which was dropped by Apple when ML was introduced (along several other GPUs too). However, you could always try the MLPF hack to run ML in 32bit mode and have graphics support through Lion kexts. Have a look at the guides published in EDP->Supported Models with Guides->Dell. It works for the D620n so it should be the same for the D820n since they are very close. Bear in mind that not everything will work as there are some secondary limitations or bugs such as connections to Windows systems or iMessage. For Mavericks, it's a total no-go in the present circumstances: no graphics support at all so, although Mavericks can be installed, it's just unusable.

The patched Atheros kext suffice. It can be placed in /E/E, followed by myFix (quick) to keep /S/L/E completely Vanilla. AirPortAtheros40.kext.zip For those who wonder about the patch, it simply consists of adding the card PCI Vendor id/Product id 0x168c/0x002b to the list of ids defined in the plist file inside the kext: <key>IONameMatch</key> <array> <string>pci168c,30</string> <string>pci168c,2a</string> <string>pci168c,2b</string> <string>pci106b,0086</string> <string>pci168c,1c</string> <string>pci168c,23</string> <string>pci168c,24</string> </array> As simple as that.

Which BIOS version do you have? My M4300 currently runs BIOS A11, I haven't updated it yet to A17, which I think is the latest. However, my DSDT is just the table from the bootpack that I have slightly amended so that graphics card reporting looks right in "About this Mac", without the multiple ",,," (small error of string length in the DSDT source code). My M4300 boots ok to Mav desktop with my modded DSDT. You didn't keep your old DSDT in a renamed form like old-DSDT.aml that you could recall manually from the Chameleon bootloader with option DSDT=/Extra/, did you? I, too, have experienced that DSDT compilation error and I believe it happens only under Mavericks. I think it's related to the way the text file is saved under Mavericks as the compilator reports some text format issue.

I'm pretty sure your latest /Extra would do just fine to give us an idea of what's required.

Guys, please post your issues in Help&Support section. This is not the place for these matters.

Ha! You can't run Mavericks on a GMA X3100-based system. Sorry, that graphics chip was dropped by Apple since Mountain Lion: ML + Mav kernels are 64bit only there are no GMA X3100 64bit kexts Apple adopted OpenGL4.x since ML and that is not supported by X3100 hardware. At best, you might manage to install ML with MLPostFactor, which is a hack to run ML in 32bit kernel mode (there are a few bugs and limitations but it runs Ok generally speaking). Have a look at macrumors.com forum for that or at our EDP->Supported Models with Guides->Dell. Failing that, you best Vanilla version will be Lion 10.7.5.

Start with the Generic one and build from there; but I'm pretty sure Rosmaniac could share his /Extra with you.

Delete unwanted kexts from /E/E or moved them to /Extra/RemovedExtensions (useful to reuse if ever required), then run myFix (quick). Regarding the files I mentioned earlier today: copy attached FakeSMC kext to /E/E FakeSMC.kext.zip copy attached DSDT + plists to /Extra DSDT.aml.zip org.chameleon.Boot.plist.zip smbios.plist.zip copy attached HWMonitor to Applications folder HWMonitor.zip run myFix (quick) and reboot. run HWMonitor and observe.

That's an issue with your headset, nothing specific to Mac OS X. Some are awkward to put back in BT pairing mode if they were already paired to a computer right before.

What are the specs of that laptop, especially the graphics card/chip?

Special kernels like Nawcom's legacy kernels do that.

Big "?" for your Quadro FX 4600 graphics card, but the rest should be Ok. Hopefully, these Xeon dual core will be better supported than some quad core that gave trouble to some users. Make sure to use one of the the latest Chameleon boot loaders. I've seen strange CPU things with r2266, but r2263 was Ok.

Enable/activate/tick/set "Generate P-Sates" and "Generate C-States".

I'll send you my M4300 kext+SMBIOS plist tonight. I guess you might have done something wrong. When you do these things, you have to make sure to remove the following kexts from /Extra/Extensions: FakeSMC v4.0 (obviously replaced by Kozlek's more recent version) CPUMonitor NullCPUPowerManagement VoodooTSCSync (keep only on systems with Intel 945GM chipset) You can also get rid of: IOATAFamily SleepEnabler Then, make sure to enable P-States & C-States in your Chameleon boot plist.

You can get a copy here: https://osxlatitude.com/index.php?/topic/2032-dell-vostro-200/ You would need to update keys and smc-compatibility with values specified above with PlistEditorPro that you can download off the web. Failing that, I'll update my M4300 files tomorrow. But you can just download Kozlek's latest version for the M4300, since it fully support 64bit kernel mode; it'll work as long as you edit the FakeSMC plist as explained in the article.

Please post the specs.

If you read our article, you'll see that our tests showed better graphics performance with MBP5,1 profile. The kexts are available from the article, look at the bottom if I remember right. If not, you can just download Kozlek's latest version, it'll be fine on the M4300. Just do the SMC + key modifications like in the article.

Atheros AR9285 works OOB. Nothing to do to activate it other than making sure it's enabled in BIOS and/or switched on.

What kexts do you have in /Extra/Extensions? Are you using a myHack USB installer?

Use Chameleon Wizard. -> PM

Make sure to check the Chameleon boot plist before you reboot and remove the i386 parameter if it ever came back...

A USB mouse should definitely work. Try to boot the USB installer with the ML bootpack.

Tried with GraphicsEnabler=No?

Just try the various PS2 kext package available in EDP; can't remember which one works Ok with Lion, but I'm pretty sure Apple PS2 kexts or myHack default kexts are Ok. ANV Slice certainly works too.

My mistake, T8300 indeed!
