EVH

Thanks so much for the reply and the suggestions bud! I confess I didn't get to even learn what was the role of EDP on that guide. I went back to it and noted the steps and references to EDP were deleted!!! I'm not sure if there were replacement steps nor have a clue about these steps to have been related to the bootloading, but I assume they were judging by the replies. I noticed also a mention in the edited guide of Chameleon right where the EDP steps were at. My units are all Nvdia. I am wondering if opencore could be a way to go, not that I know anything about it really, but just out of plain curiosity to see if any of you have experience with it. Once again thank you for the input and I think I'll put a video together at some point to showcase the experience of making music with these "obsolete" hardware/software solutions. I doubt it'll be this month though, my plate is full. Talk soon! We'll keep an eye on these topic for sure

Thanks for the links Hervé! Bookmarked them! These machines have plenty of life in them. Sure you can't watch youtuve 4k in them but you can play with a bunch of very capable software and a ton of hardware for audio that was in the hundreds of dollars is now only obsolete because most companies have decided not to update drivers. It's deliberate planned obsolescence, but the hardware that was available for these machines is now being sold for pennies and can be coupled with one of these older computers and you can keep making music. People paid hundreds of dollars for Mac computers not faster than these D620s and paid hundreds of dollars for audio hardware and recorded albums with them. You can today have it all for less than $200. Perfect for teaching audio to a student, you name it.

Hey there, Thanks for the replies. Obsolescence is in the eye of the beholder. You can install Logic Pro X on these obsolete D620's, hook them up to a $20 MIDI keyboard from a garage sale and all of the sudden you can play a collection of Synthesizers, drums, orchestral instruments, you name it. Not sure about the best way to skip the EDP portion of the guide as it was suggested above, I try to follow instructions to a T as my knowledge is limited. I imagine I could create a new guide if I succeed with installing ML on this laptop. I believe there's no need for these systems to further pollute landfills when there's quite years of use ahead of them for quite some applications but that's just my personal take, I respect other's points of view. Is opencore an option for a non UEFI computer? What would be the next stop in order to get these D620s going? I have several of them. Regards

Got across this guide here at OSXLatitude to install ML with MLPF and on step #11 and #12 refers to "EDP" and "EDP 5" respectively. A search for EDP on the site reached a page with an obituary for EDP and a link to github where the reader is supposed to find some remnants of EDP still available for download. I'm I missing a more recent guide to install ML on my D620? Thanks in advance for advice on how to proceed

SUCCESS CREATING THE USB INSTALLER Saw a very old thread here on the D620 and read something crucial about the three types of wifi cards that were used in assembling these laptops. The BIOS would show three types of wireless and if INTEL wireless was showing it had to be disabled in the BIOS or the installer would not work. Mine was INTEL, however my recollection is that I tried all of these things unsuccessfully until last night. Gave it yet another try with an old Macbook running 6.8.0, downloaded MyHack 3.3.1 from here and was finally able to create a Lion installer that reached the installer screen !!! MyHack hung at the end of the creation of the USB during the "caches part". It never told me the process completed successfully. It did ask to be patient at this stage so I left it for over 6 hours and nothing, so I pressed "cance" and then pressed "quit". Then I started MyHack again to install the "extra" folder and MyHack hung again at the end. This time I didn't cancel hours later but kind of left it a few minutes and interrupted the process again. I didn't think it was going to workbecause it never told me it succeeded but... IT DID! Haven't run the install to a drive yet but I believe I now have a good USB Lion install drive for D620 nvidia model with its bootpacks. I feel almost tempted to upload it somewhere to save someone the grief. This old operating system, (even Leopard and Snow Leopard) on these older machines works INCREDIBLE for Logic 9 (music creation program for those unfamiliar with it). You can hook it up to a $20 MIDI keyboard and a stereo or a decent set of speakers and you now you have an entire suite of professional sounds at your disposal and no hassle! I'm sure I could still use this systems 20 years from today on an old $20 garage sale beginner's keyboard. Amazing. Let's keep these computers away from the land field and recycle.

Thanks Herve for your detailed response. The processor I've got was this: SL9SE Intel Core 2 Duo T7400 2.16GHz 4MB 667MHz Processor CPU. I did toggle everything I could on the BIOS and I probably tried running the laptop without multicore support. Re: NullCPUPowerManagement, do we have a Kext library? I'm still sort of getting acquainted with the site. And thank you again bud. We'll definitely give all your suggestions a shot. Will look for the BIOS settings recommendations at once too (I don't know yet where they are but I sure should be able to find it)

Bios version is a10. I don't remember have seen an AHCI option under sata to my recollection but will check. You mean I should add that to the MyHack Extra folder? I did follow the instructions in the sense of having downloaded the correct pack which was the D620_NV110m_10.7.5_Pack for Lion installer. Shouldn't that pack be there? Should I resort to the old EDP installer method?

Update to my previous thread about installing SL on my D620. Since I was unable to get the Snow Leopard installer to go beyond 4 lines on verbose mode and I was able to run the Lion installer with rather more success I decided to install Lion. Only thing was I had a Core Duo so I upgraded the CPU and got the Lion pack with My hack 3 .3.1. I am however getting a FakeSMC fatal error (see pics). Bios version is a10 I have so far: Added the following flags at boot: -v but when that didn't work then -v -f and when that didn't work then -v -f -x Toggled ===> Virtualization on and off ===> Speed step ===> hard drive performance or bypass options Disabled -Wifi (is there a hardware button to achieve that also?) -Bluetooth -Printer port -Serial ports But Fake SMC has to do with the CPU right? (I'm a forever newbie at this) Lastly, I did apply the extra folder in MyHack. I'm attaching some pics. Any ideas? Thanks in advance for your input Here's a more complete kernel panic pic at the very end where it hangs.

Thank you so much for your reply. Does it make any difference to have the USB installer formatted as GUID vs. MBR? That was another thing I tried to toggle to see if had any luck. I wish it was linked next to the packs. For some reason I didn't know where to look for it. Will definitely give a try to the installer while disabling the wifi to see if it might move forward. I went to a torrent site for the SL installer and tried two of them. Found 10.6.0 retail and 10-.6..3 to no avail though

Has a Core Duo not the Core 2 Duo. So this is what's weird. I created the installer out of 10.6.0 version 10a432 using MyHack v3.1.2 and as Extra folder I used D620_NV110m_10.6.8_Pack that I found here. The computer starts, and gets stuck. First I tried myHack v3.3.1 and D620_NV110m_10.7.5_Pack with better results but then the screen gets black and I learned here that the reason behind that behavior is that this laptop has a Core Duo so Lion isn't an option. So went back to Snow Leopard to no avail with the MyHack method. I found the MyHack from the internet archives. There was a MBR option and I tried with it on and also off to no avail. Bios is A10. I am clearly missing something. Have to go to work now but will be back in about 8 hours and see if anyone might have any ideas about what could be wrong. Thanks in advance and best regards to everyone.
