One day I was bored and I decided to try and put OS X on my laptop and transform it from an ordinary Lenovo y50-70 into a LENOVO y50-70 HACKINTOSH (yes the caps are needed).
This will NOT be a full guide on how to put OS X on your Lenovo y50-70. These are some tips on where to start and fixes for various problems I faced when following some guides.
First, where to start. When I started I made a mistake, I followed a guide on youtube thinking that it good since it was posted about half a year ago at the time of posting this, but I was wrong, in those 6 months a lot has changed, and a lot has been made easier and this laptop is very good for Hackintosh, as mentioned here.
RehabMan’s post on tonymacx86 offers an excellent and in-depth guide on how to transform your laptop into a Hackintosh. read the post a few times so you have a good understanding of what you will be doing, backup all that you find dear and you do not wish to lose.
OSX USB Preparation
Before we even get started, there is a small problem, OS X can only be installed to USB (which is how we will be doing it) from OS X itself. The best way of tackling this is to install it on a VM. There are a few useful guides on how to do this on youtube. I recommend putting OS X El Capitan on this laptop since it works great, to do this, follow this video (it’s a guide for Yosemite) on youtube and once you get it up and running download OS X El Capitan from within the App Store, when you save it on your drive you can follow this post and use the
Option 2 (GPT, one partition) since the SSD/HDD on your Lenovo y50-70 is most likely in GPT format, but we will need to wipe everything in most cases if you want dual boot, it’s just the easiest, if you wish to try without wiping you can follow this post. Keep in mind, when adding kexts, for the internet to work after the installation we will need
RealtekRTL8111.kext which can be found in the same post, you don’t need any other internet kexts and the
GenericUSBXHCI.kext is not needed. You will, however, need the
USBXHCI_y50.kext which can be found here. Just follow the guide on installing OS X to USB and the hardest part is finished.
Now comes the part of installing and configuring dual boot. In order to do this properly our drive needs to be in GPT format and we need an EFI partition which is at least 200mb (this is important, if it’s lower then 200mb you can’t install OS X since it requires a minimum of 200mb EFI for some reason, I found this out the hard way -.-‘). I would recommend grabbing another USB and putting Windows install onto it in GPT format, Rufus is a good tool if you are on Windows and you can find guides on Google on how to do this. Once Windows is on our USB, shutdown the laptop and boot it via the recovery key left of the shutdown/startup button with your USB inserted in the right USB 2.0 slot (it can sometimes cause problems when in the USB 3.0 slot so it's always best to use the 2.0 for installing systems). Once booted via the recovery key we need to configure our bios following RehabMan’s post under the
BIOS settings part of the guide. After you have set up your bios, shutdown, and boot once again via the recovery and install Windows from USB.
NOW, THIS IS IMPORTANT: We will need to manually make the EFI partition (Windows does this automatically once you select the partition on which you wish to install Windows, but it makes a 128mb EFI, and we need a minimum of 200mb). In order to do this, we first need to format our drive to GPT. Follow these steps to convert to GPT and create the EFI partition:
- boot Windows installer USB
- at first screen press
Shift+F10to get command prompt
list disk(to you're certain on the disk you're working with, in my case confirms disk 0)
select disk 0
clean(don't blame me if you don't know what this does :-) )
create partition efi size=200
format quick fs=fat32 label="EFI"
create partition msr size=128
After this just continue your standard Windows installation via the
Custom menu. When creating partitions for Windows I would recommend 50gb for C:/, 140gb for D:/ and leave the rest unallocated (we will use this for OS X). Finish up and check if Windows boots. If it boots, good job, you have installed Windows.
Next, we need to install OS X. Insert the OS X USB we have prepared in the 2.0 USB slot and boot via the recovery key from USB. Once you boot the installer you will need to format the remaining unallocated space in Disk Utility which can be found in the menus on the top left. Once this is done install the system on your SSD/HDD. If you are not sure how to, follow this guide.
After you have installed OS X El Capitan all you have to do is configure it to suit the laptop, this has been made a LOT easier over the past few months, check out RehabMan’s post under
Post Installation. There shouldn’t be any problems here, it’s all very simple, just copy and paste the commands and you are done.
Enjoy your Lenovo y50-70 Hackintosh ^^
