Hello Folks, I was about to write this guide a weeks earlier but due to some busy days that time I couldn't write it. Sorry for late, there may be already many guide over internet on upgrading hackintosh but we (noobsplanet), explains short and fast guides as much as we can. so In short this guide explains on how to upgrade macOS Mojave to Catalina 10.15 easily which was released in October. If you're planning to install it from scratch then follow easy guide by @ALiveVam (Linked below in this article) The following are the steps you need to perform to upgrade to Catalina. This guide may not work on the system due to different hardware and config. so, additional steps may be required. I am using dell Inspiron 5559 to test and assuming to work this step perfectly who're using Intel HD 520 GPU. So, following are the 10 steps to follow:-

  1. Download the Catalina from Appstore.
  2. Download the following attached files and AptioMemoryFix. (linked below)
  3. Unzip the downloaded file (double click) and it should have an extension with SSDT-EC.aml and AptioMemoryFix.efi
  4. Mount the EFI partition. (sudo mount EFI from Terminal)
  5. Update Kexts such as Whatevergreen.kext, Lilu.kext and AppleALC.kext (You can download latest kexts from our resources.)
  6. Copy and paste SSDT-EC.aml to /EFI/Clover/ACPI/patched/ and ApptioMemoryFix.efi to /EFI/Clover/driver64UEFI folder.
  7. Once Catalina is downloaded from Appstore, goto Applications -> Double click on Install Catalina -> Follow onScreen Instructions.
  8. Mac will reboot now and in clover boot screen you'll see a new entry called "Install macOS Catalina ...."
  9. Select macOS Catalina and wait for completion.
  10. Once you're at the desktop restart the machine.
Common Problems You May Face During Installation:
If you get kernel Panic with a circle with slash logo on booting then make sure you check above step 6. This may happen when you missing SSDT-EC.aml or ApptioMemoryFix.efi.
-> If you get "The macOS Installation couldn't be completed" message then hover your mouse to the top left corner and perform the click. This will show the hidden menubar -> Apple Icon -> Select Startup Disk -> Select your installed mac drive -> Restart. Follow Step 8 and 9 from the above instructions.
-> Sound not working? -> Update AppleALC.kext (mentioned on step 5)
-> Once Installation is complete your touchpad or keyboard might now work, just reboot and it should work again.

If you're planning to fresh install or planning to install Catalina to new machine then follow the following guide.

If this guide doesn't work for you then please let me know. If you have any problems kindly ask your problem with a brief explanation in the Laptop/Desktop forum.
