触摸板的问题解决了,可以正常使用

本项目不支持z990系列,请关注以下下路标

z990系列的同学请关注 https://github.com/capricornlee/LG-Gram13-Z990

想尝试OpenCore的同学请关注(测试了一下目前bug比clover多点,还需要优化)

进一步提升体验配置(强烈推荐)

解锁CFG Lock 开启Mac原生电源管理,DVMT开启64M,彻底根除偶尔卡死、频繁花屏的bug,降低整机功耗。
方法:使用RU.efi修改BIOS配置
完整教程可以参考,http://bbs.pcbeta.com/viewthread-1840558-1-1.html
提取BIOS不需要看,只需要看后半部分即可。
解锁CFG lock,找到 cpuSetup add:0x3c val: 1->0
解锁DVMT  ,找到 saSetup add:0xDF, val: 1->2
解锁后,请删除framebuffer-fbmem、framebuffer-stolenmem 两项显卡注入属性

关于WiFi的解决办法:

1、使用USB网卡

使用免驱USB网卡(自行淘宝),打开内建网卡功能

2、通过M.2接口转接一张网卡

lg gram 有两个m.2槽位,可以通过m.2 Mkey转接卡,转接一张BCM94360cs2,可在某宝购买 (ps.拆机失去保修,谨慎操作)
硬盘位M.2不带USB接口,故无法使用蓝牙,需要自己进行焊接到主板,或者通过以下方法占用一个USB口。

3、自带type-c网卡需要安装驱动

请自行下载 https://github.com/ShiningXu/LG-Gram-macOS/blob/master/RTUNICv1.0.19.dmg

目前完成

  • 显卡正常,内屏显示正常,亮度调节正常;
  • CPU调频、电源管理正常;
  • 外接HDMI正常,可以同时使用内屏;
  • 声卡MIC正常,可使用音量调节+-快键、使用AppleALC 注入id:21;
  • 休眠睡眠唤醒正常,可使用FN+F4进行睡眠,键盘灯两档亮度正常;
  • Siri、iCloud、iMessage使用正常;
  • 电源正常,可显示电量
  • 键盘、摄像头等...都正常
  • I2C触摸板:勉强使用,存在单指卡死的BUG等,待驱动修复;

未解决问题

  • Intel网卡、SD读卡器、指纹,全球无解;
  • 遗留小问题
    • 无法使用FN 调节亮度(需要定制dsdt懒得弄了,可自定义系统快捷键解决)%

13z980 触控板驱动无效

进系统后在系统设置里可以调节触控板设置,但是触控板本身没有响应,移动,手势和点击全都没有反应。请问是需要自己额外patch DSDT之类的操作吗?

trackpad not working

machine: z980 14inch,
tried voodooI2C.kext but nothing works,
Downloaded image from official app store

Panic when coming back from Sleep

Hi! First of all, thanks a lot for this EFI. Thanks to you I got my first hackintosh running on my 15z980-g.bh72p1 (sold in Brazil).

Since my model isn't exactly the same as yours, I had o redo the USBMap, because the Bluetooth adapter wasn't being detected, and one of the usb ports didn't work.

But since I did it, I've been getting random panics when coming back to sleep. Sometimes it comes back just fine even after 12+ hours, sometimes it doesn't. This wasn't happening with your SSDTs.

This was the last report:

panic(cpu 0 caller 0xffffff800949169c): Sleep transition timed out after 180 seconds while calling power state change callbacks. Suspected bundle: com.apple.iokit.IOUSBHostFamily. Thread 0x19b5a. Failure code:: 0x00000004 00000014
(full log)

UsbMap:

SS03 is the usb port that was disabled using your SSDT-UIAC and SSDT-USBX.

Did you face anything similar to this while mapping yours?

现在OC也还可以

目前我用你的友链的OC,BIOS隐藏中把DVMT MSR啥的设置了下,自己小改了下,用intel wifi和蓝牙,可以使用,跑1天wifi还可以,比较稳定,蓝牙一样,有什么沟通群么,一块搞搞,目前有个问题是大小写锁定键的通知

Slight screen flicker in dark contents

I have a slight screen flicker that mostly happens in darker content, I have full acceleration working tho. Did someone have this problem and know how to fix it?

13z980 觸控板無效

try this one

問題描述: 觸控板可識別,但毫無反應

13z980 94360cs2+自带蓝牙体验汇报,有一点小问题

大佬好,
将情况分享如下:
使用您的efi,
触摸板工作的很好,二指可以流畅使用,lanchpad中拖动图标再也不困难了,也没有三指的bug了,
加上内建USB HS05端口和蓝牙驱动
https://github.com/zxystd/IntelBluetoothFirmware
即可识别到蓝牙

截屏2020-05-02 12 27 11

但是有几率丢失,我感觉比较莫名其妙,不知道如何解决
我是先装的系统,蓝牙也驱动了,5月1号装上94360cs2(不接蓝牙,暂时没看懂怎么动手的)后,我才发现蓝牙会丢失
经我尝试,拔下94360cs2,搭上上述蓝牙驱动和内建,可以识别到蓝牙并驱动
当接上94360cs2后,有几率丢失(我并没有做大量尝试)
最后,此蓝牙可以正常接耳机等设备,但是不能连接如下图wifi列表中“个人热点”里的手机热点,连不上
关闭蓝牙后,热点出现中正常的wifi清单里,这时候可以连上正常使用

另外,装上94360cs2后,当左侧usb插入usb3.0 u盘时,wifi会断开且尝试重新连接,但反反复复连不上,拔下usb3.0 u盘恢复正常,装右侧usb插入同样的u盘,无此问题,我试了两个u盘都是这样(同型号不同容量,不同时期买的)

iMessage无法联网认证问题

用了你的文件成功黑果,thx。
iMessage总是认证失败,这个怎么解决,需要注入白果三码吗?(用的iPhone的ID,163邮箱的)

电池充电限制到80%不起作用

当我在BIOS中将电池充电限制设置为80%时,macOS仍将其充电为100%。关于如何解决的任何想法?(When I set the battery charge limit to 80% in the bios, macOS charges it to 100% anyways. Any idea on how to solve it?)

CPU temperature issue

I am having my CPU at 3ghz with 60s to 70s when idle
I tried upgrading kext, also I got help from discord community but that too doesn’t solve the issue

hdmi外接电视音频无法输出到电视

目前其他功能几乎完美,就是使用hdmi外接电视机或者带内置音箱的显示器时,无法将音频输出切换到到电视机音响或者显示器内置音响,音频还是从笔记本扬声器输出。请问有没有解决方案呀?

13z980键盘按键映射不准确

键盘左上方ESC下面TAB上面的的那个波浪线和点的按键,无法按照原来输出,正常按下去打出来的字符是§,按住shift后打出来的字符是±,这个请问怎么解决呢?
