Just tried it on my D630 nVidia. All Ok, no need to move the app window to see frames rendering. My DSDT came from OSXL D630 ML bootpack. D630_nVidia_ML_dsdt.aml.zip You should be able to replace your DSDT file and reboot, without needing to re-install.

Ok, well you'll need: - a D620 with Broadcom wireless card (Intel not supported). Built-in Ethernet should work though. - Nawcom's ModCD burnt on a CD or DVD (Google is your friend) - Snow Leopard genuine retail image on a DVD or USB key (cheaply purchased from Apple) - a spare USB key (8Go minimum) or USB HDD to build your Vanilla (i.e. native Mac-like) installation media The following process provides a 2-phased approach: 1) a temporary installation with legacy kernel that will allow the creation of a myHack Vanilla EDP-based installation media 2) a final full-blown installation using this Vanilla installation media using the OS X Latitude EDP-based process - Boot from ModCD CD/DVD. Once you get to the fancy black installation screen, insert your Snow Leopard retail media and press F5. Once your SL media appears, select it and press ENTER. - Things will load, lots of text lines will be displayed and you should get to a graphical language selection screen. Your're starting... - Choose whatever language you fancy and you'll get to the Snow Leopard installation screen. - Re-partition & re-format the D620 HDD (GUID partition/OS X Journalised format - call it "Mac OS X" for example) through the Disk Utility available from top menu bar. Exit Disk Utility once completed. - Select newly formatted HDD ("Mac OS X" disk) and proceed with SL installation (I think you can install with ModCD default parameters, it'll be a temp installation anyway). - Once installation has finished, remove your SL retail media and reboot off your ModCD CD/DVD again. - At the fancy black screen, select your newly installed SL partition ("Mac OS X" disk/partition). This will boot your fresh SL installation which you'll be prompted to finalise (language, account name, etc.). - You should get to the SL desktop, having booted into a legacy-kernel Hackintosh. Not everything will be working at this stage. Don't worry, this is to be expected. - Connect to the Net (through Wifi or Ethernet), download myHack and install it. - From there on, you can follow the procedure detailed in the EDP section of this site, i.e. create the myHack Vanilla-kernel installation media with model-specific Bootpack. I would recommend that you copy the image of your SL retail media to the desktop prior to launching the myHack process so that you only have your final USB installation media to plug in (that way, you're less likely to make confusion between USB keys for instance). Good luck! Follow this post for an example of one of my early installations. It's a similar method: https://osxlatitude.com/index.php?/topic/147-dell-latitude-d430-thread/page__st__120 Things have evolved since (new EDP versions have been released), but the overall early/temporary installation process remains the same. Best way to learn is by trial and errors. PS: I've no D Series laptop with biometric reader, so that's one point I cannot comment on. Everything else will/should work, except screen sleep on nVidia D620s (known issue).

iboot (chameleon, stolen and rebranded)? What's that??? OSXLatitude advocates the EDP method: http://www.osxlatitude.com/edp It does require access to an existing Mac or Hackintosh to create the installation media... If you do not have such access, you can use iboot (chameleon, stolen and rebranded) or Nawcom's BootCD method (I recommend the latter) to start with and obtain an operational Hackintosh base that, albeit uncomplete/not fine-tuned, will allow you to create the EDP-based USB installation media. You would then completely re-install Mac OS X to obtain your fully operational D620 Hackintosh. On a D620: SL -> Ok Lion -> Ok (with Core 2 Duo CPU only) Mountain Lion -> NOk (no graphics support at the moment), so don't bother.

Lookup for SpeedStep and you'll find the explanation for seeing a 2.0GHz operating frequency on your 3.0GHz capable CPU. Tjmax (max. Tjunction) is a totally different thing. It is the max. T° tolerated by your CPU before it'll auto-shutdown. For CPU T° monitoring tool/app to work properly (i.e. report/display correct readings), you need to specify the Tjmax value of your CPU in the plist file of IntelCPUMonitor kext. Tjmax differs from one CPU family/model to another, so look up for your specific CPU details on Intel's web site. For Desktop CPUs, Intel seems to provide Tcase info, which differs from Tjunction... A good article on the matter here: http://www.techreaction.net/2009/10/14/guide-to-understanding-intel-temperatures/

Hi. Re: speed, don't you know about Intel SpeedStep technology?

Here's my experience with Sleep: 1) D630, GMA graphics, BIOS A17: no BIOS password required, BIOS USB-wake can be enabled without impact 2) D630, nVidia graphics, BIOS A17: no BIOS password required, BIOS USB-wake can be enabled without impact 3) D620, nVidia graphics, BIOS A10: no password required, BIOS USB-wake must be disabled or Sleep will not be operational (immediate wake upon going to sleep).

Tss, tss, tss, who hasn't done his homework? EDP provides a fix for that. Install SoundFlowerBed, set it up and those little gremlins shall be gone.

There's one or two reported T9x00-based D630s in the Benchmarks page. 800MHz FSB Penryn C2D CPUs are supported on the D630, whatever the graphics GPU.

VLC reads and plays DVDs. Use that for your DVD-based movies.

Once you've activated speech recognition and speech commands, you should have the round speech-commands button on screen. It shows the key you need to press to use speech-commands. If you don't press that key, you're only talking to your computer like Scotty talked the Apple mouse! On my laptop , it's the ESC key (I think it's the default settings). Just tried it on my D630 GMA 10.7.4 , but it seems it only supports English (just as well I don't have a French accent!): I said "Empty the trash" whilst holding the ESC key and, woof, trash emptied! There's a folder with a list of speakable items, sorted by application.

You can install ANV-Slice kext via EDP. It'll be in the list of offered kexts if you opt for your own settings instead of pre-defined ones in menu 1. But it won't provide you with 2-finger scrolling. Instead, it's all single-finger operations: move the mouse with a "light" finger on the trackpad and roll a "heavy" finger for scrolling.

Hi, you could always check if 'Wake on LAN' is not enabled in the BIOS...

Plain French works well!

Tried the -x option as well?

To get keyboard mappings + Command/Control Ok, use the following packages: DoubleCommand: -> download and install. You'll then find it on your System Pref pane. Open it and select: Command key acts as Command Key Option key acts as Command key PC style Home and End keys -> then click on Activate and save for User & System (the latter will prompt you for your password) [*]Ukele: -> only open the package (do not install anything) and browse to the Logitech directory. Then look for the 2 keyboard definition files that suit your keyboard country and copy them to the /Library/Keyboard Layouts folder. You can then select that particular keyboard in System Pref. Pane - Language & Text -> Input methods tab. For the TrackPad, try the ANV-Slice version in the EDP kexts (using own-defined settings). To replace the Wireless card, it's just like Seb said: remove the narrow plastic cover in front of the keyboard (it lifts from the right with a small flat screwdriver or knife) and remove the 3 keyboard screws. You can then lift the keyboard by slightly sliding it forward (there are small nipples at the bottom to hold it in situ) and twisting it a little on the left and right side. You'll then see the mini PCI-E wireless card. disconnect the black and white wires and using that flat screwdriver again, unplug the card. Replace it, refit everything the way it was and you should be in business straight away with Wireless capability at the next reboot.

No Mountain Lion for Intel GMA models. Those GPU are not supported, so no acceleration and bad performance.

No need to turn too many things off in the BIOS settings. Are you running the latest BIOS by the way? Things you should enable: - Multicore support - SpeedStep - HDD AHCI mode Things you can keep enabled: - USB wake - Wireless - BlueTooth Things you should disable: - Dynamic Acceleration - LAN Wake You could also try -x boot flag to run in safe mode.

Mmm... Feb 2011: http://www.osx86.net/networking-wireless/9155-dell-d620-10-6-3-all-working-but-update-10-6-6-airport-missing.html

The supported CPU models are the same whatever the D630 model: Merom (Socket P) Core2Duo with 800MHz FSB. I think Penryn are supported too (there are reported Benchmarks here for T9300-based D630). Look at the Intel web site for those CPUs in the T7000/T9000 family (T8000 should be supported too but have a reduced cache size) and go on the scrounge for whichever you fancy. You'll see there isn't that large a choice beyond a T7500...

Hi, You seem to follow the correct procedure. EDP is menu driven, so very little text to type, just numbers or "yes/no". Do you see the password prompt when you launch EDP? Or are you saying that your keyboard is non-functional at all? In that case, try an external USB one. But I guess that you must have had the keyboard working at the early stage, at least to complete installation process and create login account... For update to 10.7.4, it's very simple: you run the Combo update and, upon completion, do not reboot but re-run EDP to re-install your kexts. Then you can reboot into 10.7.4.

I can't remember which default trackpad kext is used with the pre-defined settings. But you can always change that manually. When you opt for your own settings, info is provided about each kext and some are listed as Beta release or with known bugs. In general the VoodooPS2 works really well.

That sounds like a side effect of Dynamic Acceleration being enabled in the BIOS. Your CPU has that IDA feature as far as I know and, if it's enabled in the BIOS, disable it. IDA-enabled D630s or D830s do display lower than expected frequencies. If your "About this Mac" info displays a lower than expected frequency, check what the Simulated SpeedStep tool provides in its list. On a T9800, you would expect steps of 266MHz: 2.93Ghz, 2.66GHz, 2.39GHz, 2.13GHz, 1.86GHz, etc. to whatever lowest FID (FSB multiplier) your CPU supports.

Re: Wifi cards, I think it works straight away with DW1390 and DW1490 models. DW1395 requires specific Broadcom kexts or modified IOFamily/80211 kext (can't remember its exact name, but there's a thread about it here, somewhere).

Undervolting the CPU will neither damage the CPU, nor lower performances, on the contrary. It simply aims to reduce power consumption and heat for any given performance. It is therefore a conservative/preventive modification that should, at best, maintain CPU life and extend battery usage (it discharges less rapidly due to reduced CPU consumption). It should be without effect on the GPU since it does not alter its voltage or frequency. CPU sitting close/next to GPU, one could argue that it would reduce the surrounding heat and therefore improve GPU temp, but you'd have to see... Space remains quite tight within a laptop casing.

If you don't use the -v flag, wait a few minutes after the Chameleon startup screen and see if the laptop boots with a pale/dull flat grey Apple logo. Once booted, check the selected options in your Chameleon boot plist (found in /Extra - open it with Chameleon Wizard app). If USBBusFix is checked, uncheck it and reboot.
