@Herve. That explanation made more sense. So I dropped in your Kext. I saw you already patched with PCI ids. Rebooted, and it stuck on boot. Found with -v the problem is I had left the SD Card in the slot. Not a real issue. More importantly I saw Voodoo kext getting loaded. I did see "Fail..." and "Dump..." lines on console. So tried again with SD card removed. Still don't see in System info under Card Reader or PCI sections, but decided to give it a shot. It "worked". Card was mounted on desktop and I was able to open and view the folder. However I have two problems 1) I put laptop to sleep leaving SD card in. When I resumed, I got back to desktop but laptop really sluggish. Mouse moves but I can't do anything. Also noticed Wifi and Bluetooth stop working and grayed out in task bar. USB ports also stopped working. 2) Power cycled laptop. Wanted to check if Voodoo kext causing sleep issues, because I know from prior failed experiences with card, it did break my sleep. This time never bothered to insert sd card. Simply put laptop to sleep. Then resumed. Blank display! This is interesting because seems it card in slot it wakes up, but not the other devices. But with card out, it does not find anything to wake up and thinks why bother turning display on? Needless to say, I had to power cycle the laptop. After I removed the kext, my resume-from-sleep works as before and USB ports also continue to work after resume along with wifi/bluetooth. Phew! So this is pretty much identical to anywhere I have gotten with any of my laptops as far as experimentation with SD card goes. Maybe like bronxtech said, my laptop/bios/etc maybe just too old. I will repeat the experiment with the DSDT edit as well as kext, and then only with just the DSDT. Meanwhile, if anything jumps out if you can advise...

@Bronxtech. Funny you are concluding it is CRD0. Maybe I misread the IOReg. It showed CRD0 at DDDD = 0832 while Windows is showing the SD Host Controller at 0822. Anyways, it is what it is. Regarding the BIOS - what I have is latest from Dell. @Herve. I will try your Voodoo kext. I'm assuming the way I patched it was okay (unless you also patched it), I will look. Not sure if I need both DSDT edit and Voodoo kext, so I will try all combinations and report results.

So I found (new) VoodooSDHC kext from here (even though some lamented it gives panic on 10.11.6 while allegedly working on 10.11.4) http://www.insanelymac.com/forum/topic/312536-voodoosdhc-sd-card-reader-for-el-capitan/ Patched it with my pci VVVV and DDDD. Did not work at all (while also no kernel panic, which is good) Attaching my kext, just in case I'm doing something stupid. VoodooSDHC.kext.zip

Herve, Bronxtech, JakeLo, Thought best to move SD Card conversation to this thread for I1720. So first, I have 2 hard drives in this laptop. The other is running Windows. So I know my SD Card VVVV = 1180 and DDDD = 0822. However, I cannot tell the make. Seems like a generic brand. I downloaded lspci I could find but it will not install - simply quits without doing/saying anything. I can see the card in my IOReg (attached). First when I looked at IOReg I thought it was CRD0, because CRD seemed like "card" and its DDD was 832 and I misread it as 0822. However I do indeed see 1180,0822 in my IOReg as PCI device. Problem is I cannot locate the SD Card in my DSDT (latest attached). Thinking maybe I can add the card info from IOReg registry and perhaps it will recognize it. I'm out of my element here. Regarding VoodooSDHC, I have tried two different versions. Neither worked. Not sure if any of the above is required along with VoodooSDHC or VoodooSDHC by itself will do the trick. If anyone can tell me which VoodooSDHC to try, I can give it a shot. Thanks much I1720.ioreg.zip DSDT.dsl.zip

@Herve. Got the latest Rehabman Battery and installed. DONE! Thank you so much. The install went quite fast once it got going. Every time I learn something new. Everything works great, and maybe I'm imagining it, but 10.11 seems to work noticeable faster than 10.10 on this machine. I will now continue my ritual of getting SD Card to work before giving up. I've never succeeded with SD Card but maybe this time I will get lucky. Best.

Sorry I thought I needed to see EHC1, EHC2 as well as the device names, e.g. PRT1, PRT2, etc...before it would work. So my USB Injector kext with EH01/02 was correct. All I did was search replace in DSDT ECH1-->EH01 and EHC2-->EH02, and now all USB ports work! Now my incorrect Battery Percentage in HWMonitor. How do I proceed?

Sorry Herve, trying to follow. You are saying I should also extract SSDT? And once I do that I will see names of USB devices? And then I should use those names in my Injector kext? t If so, would like to know best way of extracting SSDT. I had used DSDT Editor running it from my Windows Disk for the DSDT. Also can you comment on ACPIBatteryManager.kext? Will fixing it solve my 139% issue with HWMonitor, or am I on the wrong track?

Guys, I could really use help with two issues. - Unable to get all USB ports working. I actually noticed there are 5 USB ports, and only 3 work. I followed instructions for creating USB injector. The problem is I don't see EHC1, EHC2 device names in my DSDT (attached above). So renaming to EH01, EH02 and then linking into my Injector Kext does not work. I could of course try eliminating port count from original Apple Kext, but wanted to rule out any obvious mistakes I was making. - As expected, I got the latest HWMonitor. Seems to work for all sensors except Battery which says 139%. I tried multiple FakeSMCs, so I don't think that's the issue. Could it be I need different ACPIBatteryManager.kext?

Herve, Bronxtech. I made good progress. First, I used FakeSMC, Apple PS2 Controller and Nub, NullCPUPower kexts. VoodooPS2Controller made mouse sluggish. Second, I recalled without DSDT I had never got this laptop to boot. So I used my Yosemite DSDT. Working: Ethernet - AppleBCM440XEthernet.kext which I used with Yosemite. Have it at en0 Wifi - OOTB Bluetooth - OOTB (or maybe had a DSDT patch, can't be sure) Sleep - DSDT patches done for Yosemite must be continuing to work Semi Working: USB 2/4. Side Top and Bottom Rear work. I had USB_Injector.kext prepared on Yosemite. I recall trying to get this working. Problem is I could never locate the USB devices in my DSDT to rename EHC1/2 to EH01/02. For now I will live with 2 USB ports working. Would sure like to know what's going on though. Brightness - FN + Arrows do the trick. No Brightness Slider but can live with it. NOT Working: Battery. Try to check "Show Status in Bar" in Preferences. Will not stick. Must be because using NULLCPM kext. Can I try ACPIBatteryManager.kext and replace NULLCPM.kext? Since I used FakeSMC from D630 pack, I would use ACPIBatteryManager from there I would guess. HWMonitor and VoodooHDA I will wait until I have above sorted out. Appreciate any help. Extra folder attached. Extra_I1720.zip

Sorry Herve, having bit of an issue. I'm building USB on laptop already with El Capitan. Never did this before and Disk Utility is different. For the life of me cannot figure out how to restore the BaseSystem contents on formatted USB stick. I went to file menu-->Restore. Now what do I select? I don't see BaseSystem.dmg anywhere even though I "opened" it. So I went to Finder, and from there dragged and dropped BaseSystem.dmg in the "Restore" box. I hope that's correct. Will work through things.

@bronxtech - yes I tried with full path. Actually if I'm not mistaken I recall reading post for El Capitan I should not put full path, but I did try. @herve - The Boot Graphics option. It came with default plist when I burnt Enoch USB. I used it for all my Enoch El Capitan installs - M2400, E6500, E6510. Not sure it is significant. And I tried your VoodPS2Controller, but it made no difference. I tried with -v -f -x. Also with / without DSDT, no difference. PS - Before I did this I also came across one of your "Vanilla" kernels post and tried that too. So I'm going to rebuild my USB stick. Will try to locate latest enoch. I think 2839 is latest. Just need to know if I should use vanilla kernels from Herve or not. I'm going to start with these instructions https://osxlatitude.com/index.php?/topic/8645-dell-latitude-d630-with-core2duo-and-nvidia-quadro-nvs-135m-el-capitan/

It makes no difference bronxtech. I already tried Null kext. I feel so lame. The 1720 was indeed very hard to get to work with Y, now history seems to be repeating itself. Any other ideas? Playing with boot flags now...

@adnan. Sorry just saw this. Not sure if you are still continuing your effort. If you have same machine as I do, just google for how to burn El Capitan USB, then take my files and it should just install.

So I as waiting to see if Sierra would work on my laptop. Realized hardware is too old. However it should not be too old for El Capitan. I had it working nicely with Yosemite thanks to this forum. Now I'm trying with El Capitan and drawing a blank. I should be able to perform initial install without DSDT like I did with Yosemite with just FakeSMC and ApplePS2Controller. However I get kernel panic. My files are attached. I've renamed DSDT I used with Yosemite. Does not matter if I use it or not. The error I get is Couldn't alloc class "AppleACPIPlatformExpert", then panic on "Unable to find driver for this platform: <blah> <blah> <blah> iokit/Kernel/IOPlatformExpert.cpp:1665. If someone can please help me get started. 1720_files.zip

@Bronxtech - Actually I do, but that was left over from bootoaf instead of bootoos. It is not looking there. I got rid of it so I don't get confused again. Now after spending day on this I just took 2 hours and reinstalled everything. I see 10.11.6 officially released so I needed to do QE/CI again with new Graphics kext. Just took back up of kexts, went through the process. Everything spic and span. This is the 2nd or 3rd time with Clover I have had such random failures. Never with Chameleon. Would like to know sometime why the heck this happens. Moral of the story - if you have good backups just reinstall - not worth fretting.

Sorry guys, like I said in my 6550b thread, I couldn't get it working with UEFI, so I'm using legacy mode. I just don't get why it is failing for no reason. I'll keep at it, and if there are any suggestions...

@bronxtech - can you please clarify what you mean by set EFI path from bios config. Meanwhile, I did the following - deleted EFI partition contents completely. Then reinstalled Clover. Then copied my config.plist and my DSDT file in their appropriate locations. Then rebooted without USB stick. NOW, if found my config.plist and loaded my DSDT. However, my problem is gets stuck on random lines in verbose mode. Looks like I'm looking at a reinstall, which would suck most intensely. If anyone can suggest something?

@Jake Lo Does not seem to be my issue. When I run diskutil list I get the following /dev/disk0 (internal, physical) /dev/disk1 (external, physical) - this of course is my USB stick I now have to use before I ask it to boot the hard disk partition. Like I said, I was mighty proud of myself with this laptop. Not sure what's going on

I had a perfectly running HP Probook 6550b with 10.11.5. I went on vacation. I came back. I swear I changed nothing. All of a sudden I find my laptop will not boot. I went to "Options" on clover menu. I find that there is no selection for config. It should have said "config", i.e. conflg.plist. boot args also empty. That figures since it did not read config.plist. I swear I didn't change anything (while I know no one is going to believe me). So I stuck in my USB stick and asked it to boot from the Hard Disk partition. After it booted I took a look at my EFI partition. Nothing out of the ordinary there. I proceeded to get latest version of Clover, installed EFI partition again (of course I took a backup). It copied all new files. I rebooted. This time I see "config" selected. However, Boot Args are only showing "kext-dev-mode=1 and rootless=0". It is not picking up my boot args from config.plist. I also went and looked at my DSDT. it is not picking the .aml file I'm pointing to but one with default name DSDT.aml I'm thinking something is going wrong with mounting my EFI partition. Why I don't know. Like I said, I really, really didn't change anything at all. So at this time I can only boot off my USB and selecting hard disk partition. Can anyone help please?

All right folks. Am quite happy with my handiwork. Brightness/Backlight/Controls work. SLEEP works! Laptop will go to standby on lid close. On lid open it does not, but I can hit power button and back comes the display. Marvelous. On top of that USB works before and after sleep/wake. Nice especially if i need usb for wifi So Right now all I need is reference to wifi card that works with this laptop. I already purchased a BCM card that was not Dell branded (like DW 1520) but that also did not work. The laptop will not even go to BIOS and tells me I have incompatible device. So if someone can please refer me to a BCM or ATH wifi card. PS - One hitch. Instant wake from sleep was from HDEF and ECH2, which I think is my WebCam/Mic and SD Card. The latter I don't care about, but losing Camera makes me sad. On resume from sleep, Camera and Mic don't work until I reboot. Not a biggie since how many times does one keep using both. However if anyone can help with that would appreciate it. Attaching my files if someone can offer assistance. config_dsdt.zip IORegDump.zip

I solved my problem. Install boot0ss instead of boot0af when installing on the Hard Disk. For some reason, with this install, Windows Partition has to stay primary. I recall with my T510, I had same issue, but all I had to do was go into Windows and make the MacOS partition primary and it had worked. However, this time around I was unable to set Mac OS partition as primary from Windows. Anyways...Phew! Beats having to redo everything with UEFI (which I never got to work in first place). Update on remaining items 1) While I got the correct broadcom chip on my wifi card, I don't think DW 1520 works with HP. I need to buy different card. Appreciate insight into whether I should specifically check it works with HP machines, or something else. Don't want to keep shelling out cash for stuff that does not work. 2) I've looked high and low for DSDT patches for this laptop. Can't find a single post anywhere. I need to fix Sleep obviously. If anyone can point me to correct patches to use. 3) Camera not recognized by Image Capture. System Information does show it. Photobooth shows it. Thinking once again DSDT issue? 4) SD Card (would be a nice bonus for once) which I'm thinking is DSDT. Remaining things like brightness control, etc. I'll fiddle around with, but right now only the above are important for usability of laptop. Thanks in advance for any pointers.

Sigh. Okay. I will try installing with UEFI, I guess there's no option. Hopefully I don't even encounter the same problem again, but if I do, at least I can try what you said. One question. Should I update to the latest BIOS available? I'm at BIOS Revision 68CDF Ver. F.04. BIOS Date 10/27/2010. I have no idea what that means.

Bronxteck, I have the same exact issue. First, my problem was that my USB got corrupted. Basically I started receiving I/O failure errors. So I created new USB and installed 10.11.3. I already have Windows installed on second partition. I have since upgraded to 10.11.5 and fixed QE/CI and sound with VoodooHDA. DVD error went away too. I am thinking DW 1520 won't work and I need new Wifi. Right now need to be able to boot from Hard Disk without USB before I do anything else. Like you said, even after I installed Clover to the first Hard Disk partition, BIOS will boot to Windows. I'm trying to understand what you said about copying/renaming boot files but I don't see any Microsoft folder. If you don't mind can you please post your folder structure? I think I'll need to do something similar to what you did. Else I have to use UEFI, which means Windows install is botched and I could never install with UEFI anyways so I had disabled in first place. Awaiting your reply on folder structure. Not sure where I find /EFI/boot/Microsoft folder. I don't see it. Am I supposed to create it? And where do I find bootmgfw.efi?

Guys, I dunno why, but I'm having some trouble booting into OS after installing Clover on the Hard Drive. Like I said, I installed 10.11.3 then upgraded to 10.11.5 no sweat. Before I fixed all my peripherals I thought I would first install Clover to HD so I don't have to deal with USB stick. I copied my conflg.plist and kexts to EFI on Hard Disk. I remove the USB stick and thought I would boot to straight to HD now. Hangs without any feedback. I'm about to start over, but I'm worried I'm going to hit the same roadblock. Is there something I'm forgetting after installing Clover on the Hard Disk? Some option?

So I started with my second laptop with Intel HD Graphics (after Lenovo T510 fiasco of sorts). I used bare minimum kexts and managed to install 10.11.3. Then before I tried fixing anything else like QE/CI, I went ahead and installed 10.11.5 (1000e kext for Ethernet helped here) I tried using UEFI with Clover. After 2 weeks I gave up. Just using BIOS. I tried patching DSDT, but it was complete disaster. Googling told me DSDT was not really needed for initial installation. So my install is NOT using any DSDT at this time. These are outstanding issues, I'm listing how I plan to solve. Appreciate any help if I'm proceeding incorrectly. 1) QE/CI - I did this before once, so I'm not expecting trouble. Resolution is 1360x768 so one of the SingleLink kexts should work. 2) Trackpad does not work. Using USB mouse. Will try with VoodooPS2 kext (hopefully it will not break keyboard). Incidently, laptop will not boot with USB mouse plugged in - gives garbled screen, but I can boot then connect USB mouse and it works. Would like to know reason 3) Wifi Card - I have a DW 1520. I think it should not be whitelisted out. Would appreciate confirmation. 4) Sleep - Simply blanks screen, never goes to sleep. Thinking for *this* I might need DSDT patch. 5) Need to identify correct battery manager kext. Tried a few, but resulted in unbootable laptop. I feel good about figuring this out eventually, but if someone encountered problem with this particular laptop. Will update signature shortly with specs of laptop. Thanks for reading.
