I started a Lenovo Z470 in 11 years. It has been a few years now. I was fancy about its appearance. Now I want performance to be its short board. However, in order to work, I purchased a high-performance computer. Now I am thinking about how to deal with this small Z. Some people suggest that when the waste is sold, but it has been with me for so many years, and I can’t bear it. With a diligent and family-oriented attitude, I decided to spend more money and upgrade it. After looking for some information on the Internet, I began to sort out the ideas, summarized as follows:
- Update: Replace the original part of the hardware (sound card, network card, shell, keyboard, etc.)
- Upgrade content: memory added to 8G, add solid state drive
- System replacement: blackened apple system
The most cumbersome of these is the black apple system, which has a relatively high technical content. The first two are better (as long as it costs money). With the goal, I started to buy items from Taobao. After spending about 800 or so, I finally got all the things I needed. Ok, so let’s get started!
For the replacement of objects, there is not much to introduce here, as long as the machine will be disassembled, and the machine will be checked on the Internet before disassembling. According to the tutorial, do not blindly disassemble the machine.
Adding a memory stick is also relatively simple, and it is also a model of a memory stick compatible with the model first, and the corresponding load can be purchased.
As for installing SSD (Solid State Drive), my approach is to remove the CD-ROM drive, put the original mechanical hard disk into the CD-ROM drive (need to buy the tray), and then load the SSD into the original mechanical hard disk.
After all the above is done, Xiao Z has made a comprehensive upgrade from the hardware (the graphics card and the CPU are not recommended to change, may cause the motherboard to be damaged, and its lifting effect is not obvious). Next is the focus of this article, replacing the Apple system.
- First: check the information on the Internet, check the information on the Internet, and check the information on the Internet. . . . . Do a few more important things, learn to find your own answers.
- Second: Find out if the computer of the corresponding model has a successful case of installing Black Apple. If not, then I think it is time to give up (unless it is a technical man who specializes in Black Apple, or don’t try it easily). I think luck is better. I checked the Internet and found that there are many cases of small Z installing black apples.
- Third: According to the online successful tutorial, download the required software and copy the successful route online.
- Chameleon Bootstrap
- lazy version mirror
- Hard disk assistant
- DiskGenius Pro 4.30
The preparations are all done, then you can start doing it!
Open as an administrator:
If you click Install, there is no response, you need to open the computer disk management (right click on the computer, management), assign a drive letter to the 100M hidden disk (note that the A drive letter cannot be assigned, the remaining drive letters can be assigned), after the assignment , reopen the chameleon installer and reinstall. After the installation is complete, 3 hidden files will be generated on the C drive or 100M system hidden disk.
These 3 files are the chameleon’s boot files.
Directly double-click to run, all the way to install, the specific role of Baidu.
First allocate an 8G size area, be careful not to format. (used to put the OSX installer, equivalent to the hard disk installation disk)
Then allocate an area with no upper limit, and be careful not to format it. (used to install OSX, equivalent to the Windows C drive)
The downloaded system disk (I used the lazy version, 7.5G size), write to the newly allocated 8G disk, you need to wait a few minutes. . .
Set the 2 disks (8G, no upper limit size) and the IDs just set to AF. Right click on the change parameter and change directly to AF.
That is to put in the 8G size of the root directory.
Note: If you open the Explorer and can’t see the 8G disk, you can restart your computer and see. There is really no, it is estimated that there is a problem with the disk partition, and it may be necessary to reinstall the system.
There is a config.split file under EFI, which needs to be replaced with the edid of the computer (the replacement method is Baidu). This file is the configuration file of the clover boot, which is very important.
Rename clover.iso to wowpc.iso, then replace the C drive or wowpc.iso under the hidden disk. This chameleon guide will jump directly to the clover boot.
During the installation process, the most important thing is to see if the card will be signed or black. If these two situations occur, most of the reason is the problem of the config.split configuration file. If everything is normal, then it will successfully enter the installation interface. When choosing which disk to install, you should first select the disk tool on the menu bar to find the disk that is ready to be used to store the OSX system. Select to erase it. The format is OS (log) Format), and then back to the installation interface, you will find that you can choose which disk to install.
Wait until the installation is complete, it is almost ready to use, but the wireless network card driver and the sound driver have not been done.
Install the wireless network card driver: change the wireless network card 2a to 2b, the method is finder into the 10.11 system disk system/library/extensions/, find IO82011Family.kext, right click to display the package content to find /contents/Pluglus/AirportAtheros40.kext, continue to display the package contents , find contents/Info.pilst, open it with plistEdit Pro (install it by Baidu) and find:
Code, change 2a in the third line to 2b, save and exit, then use KCPM Utility Pro.app to repair the rebuild cache.
, restart. After rebooting, the wireless network card should be able to drive successfully.
Install the sound card driver: AppleHDA.kext driver, delete system/library/extensions/AppleHDA.kext, install with KCPM Utility Pro, the path is also system/library/extensions/, rebuild the cache after the installation is complete.
Reminder: The above process is only applicable to Lenovo Z470. For other models, please check the information on the Internet……
