    [Guide] Lenovo Ideapad S340 Laptop on Catalina

    @Patrick545 I haven't tried it lately. You might try a newer version of the BrightnessKeys.kext Found here Copy over the existing one found in your EFI folder. Update: The brightness keys (F11, F12) still work on BigSur 11.6 I updated to the lasted BrightnessKeys.kext; and (interestingly) an...

    [Guide] Lenovo Ideapad S340 Laptop on Catalina

    A complete guide is here Though, I'd recommend starting with the OpenCore Configurator app. Use it to open the config.plist file. Explore around and see what's there. The only modification is to create a Serial Number and a System UUID. I chose MacBookPro14,1 as the desired model. See attached...

    [Guide] Lenovo Ideapad S340 Laptop on Catalina

    No. Clover's config.plist is structured very differently from OpenCore's config.plist. Actually, one should be very cautious in using a config.plist from previous version of OpenCore with new/recent versions, as modifications are imposed.

    [Guide] Lenovo Ideapad S340 Laptop on Catalina

    Make a backup copy of your EFI (Clover) folder, from the EFI/ESP partition. I'd recommend copying that to a USB stick and make sure you can boot from the USB stick for backup purposes. Replace your EFI folder with the one from my previous post (Open Core). Use your own or create new Serial...

    AMD Radeon Performance Enhanced SSDT

    This guide has worked well for my RX570! Back in the Mojave days, I'd get GeekBench 5 Metal score of 43k. However, with Catalina and Big Sur, I was getting 27k. Now with the tweaks, I'm getting 44k. Nice! Though, I still have a concern... It appears the idle power consumption is still high at...

    [Guide] Lenovo Ideapad S340 Laptop on Catalina

    Hello everyone! I'm a bit late to the party, as I've been learning more about OpenCore in preparation to update my laptop (Lenovo Ideapad S340-15IWL) to Big Sur. I'm ready to share my EFI for those who may be interested. From what I can tell, everything is working: audio, video + HDMI, USB...

    Big Sur Screen Brightness Slider and F1/F2 Keys Don't Work

    FYI, with my laptop and Big Sur, the traditional renaming (_Q11 -> XQ11 and _Q12 -> XQ12) of the Function Keys (F11,F12) for brightness control did *not* work. (It did work in Catalina). Fortunately, the BrightnessKeys kext did the job.

    [Stable] Nicoras' Mac: H370M Bazooka + Vega 56 | OpenCore-based

    If anyone is curious; with OpenCore 0.6.3, this build (MSI Bazooka H370M) runs Big Sur wonderfully.

    macOS 11.0 Big Sur is Now Available on the Mac App Store

    It took the plunge....starting with switching to OpenCore on my main hack. Installing BigSur was a breeze after that.

    [Guide] Lenovo Ideapad S340 Laptop on Catalina

    Hi all. FYI mine works with HDMI. I believe in 10.15.4 there were changes in the framebuffer handling. Check your framebuffer patching, make sure your device-id is set to 0x3E9B0000 Also, be sure WhateverGreen is the latest version. More/complete framebuffer patching would be this...

    pastrychef's Asus ROG Strix Z370-G Gaming (WI-FI AC) build w/ i9-9900K + AMD Vega 56

    Greetings! Well, I've updated my main hack to Catalina (10.15.6) from Mojave (10.14.6) and all seems to be running fine. Though, my Geekbench 5 scores for AMD RX570 GPU (OpenCL and Metal) have dropped significantly; roughly 30-40% lower. Have I missed something? Booting to a temporary install of...

    pastrychef's Asus ROG Strix Z370-G Gaming (WI-FI AC) build w/ i9-9900K + AMD Vega 56

    This happened to me when updating USBInjectAll from 0.7.3 to 0.7.5 Reverting to the previous version (0.7.3) fixed it. Check the version of that kext, or maybe create a custom USB kext with Hackintool.

    Apple Previews macOS 11.0 Big Sur - Available Fall 2020

    Wow! It would apparently seem so. With macOS Big Sur supporting Intel CPUs and the (now) use of 10th generation iCore CPUs, it's promising that hackintoshing with newer/current components is a reality. Keeping with Apple's trend, support will likely continue for a few (3?) years to come. Hooray!

    Thank you! This information and some framebuffer tweaking allowed me to install 10.15.6 on my i3-8100 (iGPU) based hack.
