Guide:

If you're looking to install Big Sur on your Acer Aspire E1-570 and encounter any issues or want to optimize the system further, here's a guide to help you:

1. Pre-Installation Preparation:

• Ensure you have a macOS Big Sur installer downloaded from the App Store or obtained from a trusted source.
• Create a bootable USB installer using tools like gibMacOS or createinstallmedia.

2. BIOS Settings:

• Access your laptop's BIOS settings and configure them as follows:
  • Enable UEFI boot mode.
  • Disable Secure Boot.
  • Set SATA mode to AHCI.

3. OpenCore Configuration:

• Set up OpenCore bootloader by following the Dortania OpenCore Install Guide for Intel Ivy Bridge systems.
• Customize your config.plist according to your hardware specifications and requirements. Pay attention to ACPI, Kernel, DeviceProperties, and other relevant sections.

4. Kexts and Drivers:

• Ensure you have the necessary kexts and drivers in your EFI folder. Common kexts include Lilu, WhateverGreen, VirtualSMC, AppleALC, and appropriate Ethernet and Wi-Fi kexts for your Broadcom and Qualcomm Atheros cards.
• Use Hackintool or similar tools to generate SSDTs and customize ACPI patches for your system.

5. Post-Installation Tweaks:

• After successfully booting into macOS, install additional kexts using a tool like Hackintool or Hackintosh-specific package managers (e.g., Hackintool, OpenCore Configurator).
• Apply any necessary fixes for sleep, brightness control, microphone, and other non-working features. Refer to online forums, Hackintosh communities, and guides specific to your laptop model for troubleshooting steps.

6. Wi-Fi and Bluetooth Upgrade:

• Consider replacing the Qualcomm Atheros Wi-Fi card with a compatible Intel one for better compatibility and performance. Ensure you use a supported model to avoid compatibility issues.

• Join Hackintosh forums, Discord servers, and online communities for additional support, troubleshooting tips, and resources specific to Acer laptops and Big Sur installations.
• Share your experiences, ask questions, and contribute to the community to help others with similar setups.
