Summary: I upgraded my 6 year old Macbook Pro 13" from 3DMark 11 gaming performance P721 to P9412 and play recent games with highest settings.
I recently was looking for a new notebook with Thunderbolt 3 to replace my late 2012 Macbook Pro 13 inch. I wanted to play some games but didn't want to buy a desktop PC. So it has to be a notebook with Thunderbolt 3 so I could attach an eGPU to the USB-C port.
During my research I found egpu.io where I could read about external GPUs that are available on the market. I also learned about Thunderbolt 3 to Thunderbolt 2/1 adapter. There were other Macbook Pro owners who succeeded to get eGPU to run with an adapter.
I decided to try and upgrade an old Macbook Pro Retina 13-inch late 2012 because it was still fast enough for me.
I read many success stories and started collecting information about what which steps to do. All include multiple steps and have different aproaches and need some experimenting.
My starting point is: I have a Macbook Pro with only Windows 10 installed . I have no MacOS X partition left because I deleted them all.
- Late 2012 13" Retina Macbook Pro i7 2.9 GHz, (Turbo Boost 3.6 GHz)
- 8 GB 1600 MHz DDR3L
- 256 GB SSD
- Intel HD Graphics 4000
- 2x Thunderbolt 1 (up to 10 Gbit/s)
- Gigabyte Aorus Gaming Box
- NVIDIA GTX 1080
- Thunderbolt 2 cable
- Thunderbolt 3 to Thunderbolt 2 adapter
Installation stepsDownload Software

BackupBackup my Windows installation and create a recovery stick.
SIPDisable SIP (System Integrity Protection) - I have no running Mac OS X installed but can start MacOS X Internet Recovery Mode.
- Start Internet Recovery Mode, press CMD + ALT + R after power on
- Connect to the internet with WiFi
- Open a terminal and execute
- Execute the command
Install EFISpoof the system to not disable the iGPU when an external GPU was detected. This is the most confusing part. I did manage to get my Macbook Pro to not boot several times because of trial-and-error approach.
I did install rEFInd following the instructions at http://www.rodsbooks.com/refind/installing.html#windows it didn't work exactly. Here are my modifed steps:
- Extract the zip file
- In refind folder, remove aa64 and ia32 folders and efi files. The are not used.
- Copy apple_set_os.efi to the refind folder
- Rename refind.conf-sample to refind.conf
- Open the command prompt windows as administrator
mountvol S: /S
- Copy contents of
xcopy /E refind S:\EFI\Boot
- Change to drive
- Rename .efi files.
rename bootx64.efi windows64.efiand
rename apple_set_os.efi bootx64.efi
Working Using the external GPU with internal and external screen. Playing games with highest settings. The results using the external screen is better.
Not working USB Hub on the Aorus Gaming Box The 2 small fans are not running.
