ACER ASPIRE E1-572G HACKINTOSH

ACER ASPIRE E1-572G HACKINTOSH

• CPU: i5-4200U Haswell-U
• iGPU: Intel HD Graphics 4400
• RAM: 1x Kingston DDR3L 4GB 1600 MHz
• Motherboard/Laptop Make and Model: Acer Aspire E1-572G
• Audio Codec: Realtek ALC282, alcid:28
• Ethernet Card: BCM57786
• Wifi/BT Card: Qualcomm Atheros AR9565, replaced with Intel Centrino Wireless-N 1030
• Touchpad and touch display devices:
• BIOS revision: InsydeH20 2.17

What's not working?

• AR9565, on Monterey and newer. Available kexts are only supported up to Big Sur with a really slow internet speed.
• Airdrop, and other Airport related features
• DRM, no Netflix on Safari!
• Brightness Keys, Fn+Left/Right

Fixes

• Wake from Sleep causes Restart:
  • SSDT-GPRW.aml, and
  • RTC-blacklist (at B2 for me)
    • Requires RTCMemoryFixup.kext.
• No Sleep if Closing the Lid:
  • HibernationFixup.kext
    • boot-arg hbfx-ahbm=3
    • Type in terminal sudo pmset -a hibernatemode 25
• Shutdown do not fully power down:
  • Update to the latest BIOS
• Ethernet not detected:
  • For Catalina and older:
    • Under Device Properties > PciRoot(0x0)/Pci(0x1C,0x0)/Pci(0x0,0x0),
    • Add device-id | B4160000 | DATA
  • For Big Sur and newer: Add ModifiedAppleBCM5701Family, this works for any Broadcom Ethernet that was already supported in older macOS versions, just add your device-id inside the kext's plist file.

Cosmetic Fixes

Under PciRoot(0x0)/Pci(0x2,0x0):

• Smooth Brightness Slider:
  • backlight-smoother-interval | 08000000 | Data
  • backlight-smoother-steps | 25000000 | Data
  • backlight-smoother-threshold | 00000000 | Data
  • enable-backlight-smoother | 01000000 | Data
• Prevent the screen backlight to fully off when Brightness is set to the lowest:
  • backlight-smoother-lowerbound | 05000000 | Data

​

Other Issues

• HDMI Audio, Not fixed, I don't have a device to retest it at the moment.
• Wake when opening Lid, requires keyboard tap to wake. Partially broken according to guide, they recommend disabling it.
• Antenna of the WiFi Card: I didn't know AR9565 only had one one! So buy the right antennas if you are replacing.
• CFG Unlock: I was not able to unlock this, I had to search “MSR Lock” instead of “CFG Lock”, here are the values I found:
  • VarStoreInfo (VarOffset/VarName): 0x1B1, VarStore: 0x1234
  • Disabled, Value : 0x0
  • Enabled, Value : 0x1 (default)
  • VarStoreId: 0x1234 Name: SystemConfig

If you want to attempt anyway, you will not find the “SystemConfig” when booting RU.efi.

^{This is a repost with an updated information with fixes, old post was somehow removed by reddit and labeled it as spam. I know Monterey is the latest supported macOS for Haswell, I am just waiting for my Airport Card to arrive, and then I'll update it to Sonoma and use OCLP. If you're going to ask, "you only have a MPCIE slot, how is it going to fit?", the laptop originally had optical drive/DVD and it was removed and was replaced by a plastic dummy, and it's hollow. I ordered a pcie extension cable and an adapter.}
