Get an older Clover version... It changed folder structure around version 5000

Your EFI is probably using the old folder structure and most likely will work with Clover 4976

My laptop is connected to a monitor most of the time and I don’t let it sleep most days. So, losing BT after sleep isn’t an issue for me, but I spent some time researching and trying different stuff. Here’s shortly what I am sure:

The BT chip must get its firmware injected when powered on. It loses the firmware when powered down during sleep. Clover does it fine with the injector kext. I tried putting the kexts in every ext location and sometimes one kext in Clover and other two in SLE or LE or Apple/Internal/Extensions , but nothing worked. BT only works after boot when injector kext is in Clover. 
 

I won’t spend more time on this because I use BT under 5 times per month. 

I installed fresh Catalina 10.15.2 (19C57) on my E7240 with DW1550 (PCIe connector). It's the same chip as your DW1560 (NGFF/m.2 connector).

Bluetooth works fine for me with the suggested kexts, but it can't get online after sleep.

As far as I understand, the driver/firmware has to be injected every time when the chip is power on.

It seems Clover does it OK, but after waking up - nothing does it again.

I will use my system for few more days and complete the setup, so I can clone the SSD. Then, I will play more with this.

What is your experience till now ?

Here is a list of all my kexts and their versions. They are all in Clover. I have none in /Library/Extensions.

I am afraid that I can't do this in the next 2 weeks.  I actually bricked my MacOS by trying to solve this and I decided to go back to my Mojave backup. I was surprised to see that my APFS is corrupted in the Mojave SSD image backup, but the system is usable. I consider going with a clean Catalina install in the first week of 2020. I will certainly update this thread with my results.

I am unable to get BT working on 10.15.2 . I have E7240 with DW1550, which is essentially the same chip as DW1560.

I have the feeling that it's something USB power related as BT device is detected, but unable to connect to anything.

I have E7240 (DW1550 for wifi and BT) running Catalina 10.15.1 (19B88) with Clover r.5093 and I don't have any issues.

I have attached my bootpack. Please make sure to shuffle the serial number in the config.plist with Clover Configurator.

I hope it helps you and anyone else who is trying to install Catalina on E7240 laptops.

E7240+DW1550.zip

Unfortunately, it does not help.  I also found that I have some problem with APFS.

My preferences pane issues might be related to the filesystem issue. Most likely, I will do a clean install in the near future.

Hello Guys,

I have updated my E7240 to 10.14.3 (18D109) and it went fine, however I can't click the icon Security & Privacy in System Preferences and the Software update icon is also missing.

I have attached screenshots. Does anyone has the same issue ? What could possibly be wrong ?

It turned out that DW5570 can't be used in High Sierra, because there's no easy way to turn the card in online status.

It stays by default in low power mode, and the windows driver activates it.  Linux guys had the same issue as the one I have in High Sierra, but they made a solution: https://sigquit.wordpress.com/2015/02/09/dell-branded-sierra-wireless-3g4g-modem-not-online/

Basically, I could not google successfully and find a way to send qmi command to the modem with FCC authentication, which will turn it on.

I have decided to order Ericsson F5521GW which is known to work fine on High Sierra.  I hope that I will never have to use 4G internet, but I must absolutely have this type of alternative link, which costs 5 euro to activate a pre-paid SIM, which will be active for 1 year and has unlimited data transfer at 128Kbps. Yeah, I know it's slow but for some stuff - you don't need speed, just active connectivity

@viking1304 - Thanks for the advice.  My E7240 is showing the DW5570 as recognized WWAN after switching to 14 and using your kext.

Unfortunately, I do not have a SIM card with that particular size, which I can put inside to test if Internet works fine now.

No issues after update on my E6220 , it has 8GB RAM , so video memory is 512MB and no glitches and no problems with Safari and CPU

I do not know what is the issue with the issue mnx's installer.

Follow up on the thread if Sierra is possible....Today I updated via App store to 10.12.2 - all good except for sound.

I just used the old kext used during installation and rebuilt kernel cache and sound is working now. I do not see any other issues.

Yes, I recommend to follow the Herve's Enoch guide. It's definitely much better than mine. I made mine, because for some unknown reason many people want to use Clover and they send me private messages.

I am not an expert, but I have a perfectly working system without any issues.

I use Clover, because the first guide which I tried was about Clover and I don't really want to try to change the bootloader.

I can only guess that you have an awkward partition table or you did something wrong with Clover install options. Never seen this exact same error before.If something wrong with BIOS options or BIOS version - you may have issues with Herve's guide as well.

Thanks for the suggestions. I will test and try it. I hope that even if I break something, I have enough experience to recover the OS.

I'd update the guide short afterwards once I have personal success setting it that way.

Is it allowed to upload TrackpadPrefpane from El Capitan to help people who also have issue with it ? Or it's better to provide an external download link ?

UPDATE: I have tried the improvements suggested by Herve and I almost screwed a perfectly working system. Maybe I am a lucky idiot, who is not experience in hackintoshing, but I managed to get a perfectly working system and I will not risk changing the settings again.

It turned out that I uploaded messed up config.plist ,so I fixed that and uploaded again

UPDATE 2

Appstore update to 10.12.2 - all good except for AppleHDA, which was replaced by the update. I just used the old kext used during installation and rebuild kernel cache and sound is working now. I do not see any other issues.

Hello,
 
I'd like to contribute to the forum and I have decided to write a detailed guide how I installed macOS Sierra 10.12.1 on my E6220 with Core-i7 2620m, HD3000, 8GB RAM, 128GB SSD. I have received few personal messages for help, although there’s a perfect Enoch guide by Herve:
https://osxlatitude.com/index.php?/topic/7914-dell-latitude-e6220-with-i5-2520m-hd3000-and-1366x768-lcd-mavericksyosemiteel-capitansierra/
and excellent generic El Capitan guide by Jake Lo:
https://osxlatitude.com/index.php?/topic/8506-dell-latitude-inspiron-precision-el-capitan-clover-guide/
 
I will follow Jake’s guide, but I will add more stuff and this guide will be useful for all Sandy bridge E6x20
 
Many thanks to all OS X latitude forum members, who helped me when I was very new to OS X.
 
Let’s start. You need:
1. E6220
2. 8GB USB or bigger
3.  Access to real mac to create install USB or if you have Windows/Linux you can use a virtual machine using virtualbox or vmmare
 
You should update your BIOS to A13 and set it to the following settings :
https://osxlatitude.com/index.php?/topic/8281-e6220-bios-settings/
 
Download macOS Sierra from Apple store.
 
Prepare USB using the following instructions:
 
1: Prepare Bootable USB Drive
This step extracts the OS X Installer contents, then installs Clover bootloader to the USB stick.
 
1. Insert the USB drive on a running OS X system
2. Open /Applications/Utilities/Disk Utility
3. Highlight the USB drive in left column
4. Click on the Partition tab
5. Click Current and choose 1 Partition
6. Click Options...
7. Choose GUID Partition Table
8. Under Name: type USB (You can rename it later)
9. Under Format: choose Mac OS Extended (Journaled)
10. Click Apply then Partition
11. Go to Applications, right click on “Install macOS Sierraâ€/Show Package Contents/Contents/ SharedSupport
12. Mount InstallESD.dmg
13. Launch ShowHiddenFiles and select “Show Special Files†( app attached at the end of guide)
14. Mount BaseSystem.dmg (hidden) from “OS X Install ESDâ€
15. Use Disk Utility to restore “OS X Base System†to USB (see image below)
      
16. After restore is complete, USB is now renamed to “OS X Base Systemâ€. Go ahead and rename it to “Install macOS Sierraâ€
17. Go to “Install macOS Sierraâ€/System/Installation and delete the alias “Packagesâ€.
18. Copy “Packages†from root of “OS X Install ESD†to “Install macOS Sierraâ€/System/Installation
19. Copy BaseSystem.dmg and BaseSystem.chunklist (hidden files) from “OS X Install ESD†to root of â€œInstall macOS Sierraâ€
20. Launch ShowHiddenFiles and select “Hide Special Filesâ€
21. Download Clover EFI boot loader
22. Open Clover package installer
23. Hit Continue, Continue, Change Install Location...
25. Choose “Install macOS Sierraâ€
26. Hit Continue, then hit Customize. Select these items:
 
• Install Clover in the ESP
• Bootloader/Install boot0af in MBR
• CloverEFI/CloverEFI 64-bits SATA
 
You can also select a Clover theme.
 
27. Click Install
28. After installation of Clover, the hidden EFI Partition will appear on the Desktop
 
Now you will need to browse the EFI partition and put the necessary files in the correct locations:
 
DSDT.aml and ssdt.aml should be copied to EFI partition and folders CLOVER->ACPI->patched
 
Important note: if you have different CPU and you use my ssdt.aml - you will get kernel panic. If you have i5-2520M which seems to be the most common - you can get ssdt.aml from the files provided in Herve’s guide - https://osxlatitude.com/index.php?/topic/7914-dell-latitude-e6220-with-i5-2520m-hd3000-and-1366x768-lcd-mavericksyosemiteel-capitansierra/
 
If you have another CPU - then don’t use ssdt.aml and find NullCPUPowerManagement.kext, which should be added along with the other kexts. As of this writing, I do not know which is the latest such kext working OK with Sierra. If someone is ready to provide it - I can add it to the post. You can use a shell script ssdtPRGen.sh to generate ssdt.aml for your CPU after the install. The script is provided in the Tools zip to this post. You might want to google for a newer version.
 
Kexts should go to EFI/CLOVER/kexts/10.12/
 
config.plist goes to EFI/CLOVER/
 
Please use Clover Configurator to generate a new serial.
Just start Clover Configurator - File - Open - select config.plist from 
EFI/CLOVER/ and open it. Then SMBIOS from the left-hand list and click the magic wand and select first laptop picture and from the menu Macbook Pro 8,2 or 8,1 if you have the i5 processor. You can choose year of manufacture and click the buttons ‘shake’ to get different serials generated. When done - click File - Save.
 
Now you can reboot computer and start the installation. You can press F12 before boot and choose USB.

If you get kernel panic - one common reason would be if you have empty DIMM A slot, and only 1 RAM stick in DIMM B.

Move the RAM to DIMM A and try again.

 
For a new installation of macOS, you MUST erase and format the destination drive according to the following steps before continuing.  
   a. From the menu bar, click Utilities -> Choose Disk Utility
   b. Highlight your target hard drive for the macOS installation in left column.
   c. Click Erase tab
   d. Under Scheme: GUID Partition Map
   e. Under Name: type Macintosh SSD (You can rename it later)
   f. Under Format: choose Mac OS Extended (Journaled)
   g. Click Erase
   h. Click on Partition Tab to add more partition if you prefer
   i. Close Disk Utility
 
Click Continue, Continue, Agree
Select Macintosh SSD, or name of your existing drive, where you want to install macOS and click Continue
Upon completion, system will restart
Press the F12 to choose boot device
Choose <Your USB Installer device>
When Clover boot screen appears, choose Macintosh SSD or name of your existing drive
 
The system will boot into the new drive, and complete the installation…
 
Launch the terminal and enter the following command
 
diskutil list
 
If you something about virtual drive like this:
     /dev/disk1 (internal, virtual):
 
Please enter the below command if you have only one disk and you are not setting up dual-booting:
 
diskutil cs revert /dev/disk1
 
Otherwise you have to find out which is the correct ending number from the data you see from “diskutil listâ€.
 
Then create a folder and mount EFI partition:
 
sudo mkdir /Volumes/efi
 
sudo mount -t msdos /dev/disk0s1 /Volumes/efi
 
Now it’s the time to run Clover installer and install on your HDD/SSD in a similar way like when preparing the USB, however please select couple of more options:
• Install Clover in the ESP
• Bootloader/Install boot0af in MBR
• CloverEFI/CloverEFI 64-bits SATA
   • Install RC scripts on target volume
• Install Clover Preference Panel 
Copy DSDT, SSDT, kexts and config.plist to the EFI partition of your HDD. You can use EFI mounter if for some reason - it is not mounted after Clover install.
 
Now let’s fix the audio:
 
Copy AppleHDA_IDT92HD90.kext to /Library/Extensions
Copy AppleHDA.kext to /System/Library/Extensions
 
Repair permission and rebuild cache. Run command from terminal
 
      sudo chmod -Rf 755 /L*/E*
      sudo chown -Rf 0:0 /L*/E*
      sudo touch -f /L*/E*
      sudo chmod -Rf 755 /S*/L*/E*
      sudo chown -Rf 0:0 /S*/L*/E*
      sudo touch -f /S*/L*/E*
      sudo kextcache -Boot -U /
 
Make sure to disable hibernation as it's a prerequisite to get sleep & wake to work Ok on a Hackintosh:
• sudo pmset hibernatemode 0
• sudo rm -f /var/vm/sleepimage
• sudo pmset hibernatefile /dev/null
 
 
Remove USB and reboot. You system should start fine, but you might notice that if you tap on the touchpad - it does not click.
Moreover, Trackpad preference panel may not load.
 
This is easily fixed by deleting:
 
/System/Library/PreferencePanes/Trackpad.prefPane
 
and replacing it with a Trackpad panel from El capitan. 

Link to download: http://www.megafileupload.com/85j1/Trackpad.prefPane.zip
 
I still had a persisting problem that whatever I set in Trackpad preferences - it’s not saved after reboot, so I used Dr. Hurt's app - Touchpad Settings.app , which I copied to the Applications folder and allowed access from System Preferences - Security & Privacy - Accessibility - Allow the apps below to control your computer and I added Touchpad settings.
 
I really hope that this will be very helpful to people new to hackintoshing and have Sandy Bridge models E6x20.
 
PS. I may have missed something and fix it later. More stuff could be added later, or improve formatting.
Feel free to criticize me and point out if I am doing something the wrong way
English is not my native language, but I think I have provided clear enough explanations.

E6220-i7 2620m.zip

Herve, you are the most helpful person I have ever met online !!!

I have sound working (including via HDMI) and the mic as well. 

Trackpad preference panel is blank in System Preferences, but I googled and found that it's a known issue with a solution to replace it somehow using stuff from El Capitan, but I am too tired and it's very late evening now. I will sure fix this last bit.

I have attached all the files I have used for my system - E6220 - Core i7 2620m

E6220-i7-2620m-Sierra.zip

Tested with Sierra 10.12.1 (16B2657) and Clover version is 3899.

Thanks again !

I have used the same kexts from El Capitan with latest Clover 3899. (Kexts from Jake Lo's guide - https://osxlatitude.com/index.php?/topic/8506-dell-latitude-inspiron-precision-el-capitan-clover-guide/ 

I only replaced the VoodooPS2Controller.kext from Herve's Enoch guide.

I have two things which are not working:

1. My touchpad can't be used to 'click' by touch when system loads. 

I remember the option in System Preferences -> Trackpad to enable it, however it loads blank.

Anyway, when I click on Trackpad - it fixes the issue and now I can 'left-click' if I tap..

2. Audio - I can't seem to get audio kext to work. I have tried many different things, and I am worried that I always get such warning when rebuilding kernel cache:

symlink("/System/Library/PrelinkedKernels/prelinkedkernel", "/System/Library/Caches/com.apple.kext.caches/Startup/kernelcache") failed 17 (File exists) <createPrelinkedKernel 2795>

Thanks for the clarification. I will just take  Dr Hurt's VoodooPS2Controller Release 4 from your bootpack and re-use same kexts from El Cap.

I hope for a flawless update

@torakikii - You may eventually decide to use Clover, once you get more Hackintosh experience, and most likely after few macOS updates break your system and you re-install few times.

I thought there are still ongoing issues with Sierra on E6220. I will try to update tonight or tomorrow.

I am using Clover on the fly updates, and I will provide info what happened and upload the kexts, which I am using.

I have E6220 and I am perfectly happy with El Capitan. Everything is working, no issues.

So far, I do not see a reason to go for Sierra.  I know for sure that one of the forum admins Herve is running Sierra on his E6220

Maybe he will update his series of guides sometime, but so far - I'd recommend to follow this guide for El Capitan:

https://osxlatitude.com/index.php?/topic/8506-dell-latitude-inspiron-precision-el-capitan-clover-guide/

I had troubles with VoodooPS2Controller on my E6220 with Clover, but it was fixed when I installed an older Clover version r3333

I really can't explain why but it solved the issue.

PS. It's the same kext from Herve's e6220 guide for Enoch

Great, this means that we will surely have a new Skylake Macbook Pro this year.

Have you tried if touchscreen works in OS X 10.11.4 with those E7270/E7470?

It's interesting to check if latest OS X already has some touchscreen support ?

I had the same kernel panic on my E6220.

Look at this line about CoreStorage:

"last loaded kext at 3211438929: com.apple.driver.CoreStorageFsck 517.20.1 (addr 0xffffff7fa1bab000, size 106496)"

I did nothing special, I just pressed Space when Clover shows up and selected Safe mode and try to boot.

Once it boot OK , I used "diskutil cs revert /dev/disk1" ,so there are no virtual drives.

The second time I had kernel panic after 10.11.4, which I didn't even read -  I selected to run without cache from the Clover menu and then flying messages on the LCD screen and I left it for 30 minutes. When I came back - it was at login screen.

I have no idea what is going on after the update to 10.11.4, but it seems that El Cap recovers by itself.

Hello Guys,

I managed to install El Capitan on my E6220 with i7 2620M. I had a problem for the past 3 months and I couldn't start the installer, whatever I tried.

The installer always rebooted the system after showing a line full of plus signs "+++++++++++++++++++++++++++++"

I've added so many boot flags to clover and finally got the system to show some other error message before the "+++++++++++++++++++", but it was impossible to read it, because the laptop reboots after few milliseconds.  I created a video with my phone and then examined every frame and saw that the error is: 

panic( cpu 0 caller 0xffffff808032ffb6):"zone_init:kmem_suballoc failed"

I googled the error and I found that Clover has an issue if your only 4GB RAM stick is in DIMM-B , and not in the primary DIMM-A slot.

I changed the location of the memory module and there's no problem now.

I have a question:  Should I proceed with the "MacBook Pro EFI Firmware Update 2.7" which AppleStore insists that I install ?

Thanks for the suggestion. I actually gave up. I have tried twice (this month and in November) to install El Capitan and I end up breaking my perfectly working Yosemite.

I don't seem to be able to use chameleon or enoch, they never boot, but Clover works perfect every time with Yosemite, but something is wrong with El Capitan.

You can close the topic, I will try again after few months.
