Guide: If you're encountering issues reaching the installer page for macOS Catalina despite successful installations of previous macOS versions like High Sierra or Mojave, follow these troubleshooting steps to address the problem: 1. Verify USB Installer Integrity: Ensure that your macOS Catalina installer USB drive is created correctly using a genuine macOS Catalina image and tools like createinstallmedia or gibMacOS. Double-check that the USB drive is formatted appropriately (Mac OS Extended (Journaled) or APFS) and has the necessary EFI partition for booting. 2. USB Port and Drive Compatibility: Test different USB ports on your computer to rule out any compatibility issues with specific ports. Try using a different USB drive if possible, as some drives may not be compatible with macOS booting requirements. 3. Boot Flags and Bootloader Configuration: Review the boot flags you've added, such as npci=0x3000, and experiment with alternative flags or combinations to see if they r...

Facing installation issues during a Hackintosh setup, especially for beginners, can be quite challenging. The error message "macOS could not be installed on your computer" during the Catalina installation indicates a problem that could be related to several factors, such as your EFI configuration, hardware compatibility, or the installation media itself. Let's go through some steps to troubleshoot this: Guide Step by Step: Verify Your EFI Folder : Ensure that your EFI folder is correctly set up for your specific hardware. Since you're using OpenCore 9.6 Debug version, make sure all the kexts, drivers, and ACPI patches are compatible with Catalina and your hardware. Pay special attention to the config.plist file. Validate it using OpenCore's configuration checker to ensure there are no syntax errors or misconfigurations. Create a Fresh Installer : Sometimes, the issue can be with the installation media. Create a new Catalina bootable installer using a reliable guid...

I tried updating to Catalina without tidying up the EFI folder, and assuming I had the most-recent-back-then version of Clover, but I have the 2.4 the still-Mojave-named boot from Clover launches the Apple logo, and the load animation goes all the way and gives me hope, but then moves on to a black screen. Same happens when launching recovery installs from Clover. I didn't keep my bootable USB key, so for now I'm stuck with black screens and not being able to run a terminal or post-intall...

Hi, I dont know what is wrong but safari and firefox not working on my z490 with Catalina. I use iMac20.1. I have this issu only on Catalina. Author: msh SOLUTIONS: It's not uncommon to encounter software quirks and compatibility issues with Hackintosh setups, especially when mixing hardware and macOS versions that Apple doesn't officially support together. Here are a few steps you can take to troubleshoot Safari and Firefox not working on your Hackintosh: Ethernet and Network: macOS relies heavily on an active internet connection for many functionalities, including Safari. Ensure your Ethernet (or Wi-Fi, if that's what you use) kext is correctly set up. Check if the internet is working correctly in other apps. Check your system's System Preferences -> Network settings to ensure everything looks okay. Update Kexts and Clover/OpenCore: Make sure all your kexts are updated, especially Lilu.kext and any network-related kexts. If you're using Clover, consider ...
