Before you try any of these modifications, we highly recommend you to watch all videos in the playlist and make sure to understand them all, only then you can execute the modifications. By all means, you are performing all these soldering AT YOUR OWN RISK.

FAQ:

1. When is the X-GPU for the iMac and MacBook will be released to the modders?
We are trying hard finalizing the final design & installation method for the whole system that is intended to ease the modders installing on their own, and you need to understand all these RnD and projects are coming from our own pocket(mostly logicboard repairs), not crowdfunded source. So every PCB revisions are manufactured only after they are carefully designed and revised, we're not gonna produce another PCB batch just to correct a drill hole mistake! and every penny from our own pocket counts. But no worries, we are trying our best!

2. Why did we make it?
We built it for fun, the original thoughts when this project started was just because we want to have an ideal laptop that we can use for ourselves; upgradable, repairable; these models are known for its high repairability rate and its parts are cheap, so they're easy to maintain for everyday use for a repair shop like us. We also create it just to test our soldering skills and manufacturing precision.

3. Can I edit 4K after upgrading to NVMe SSD?
The short answer is NO, it requires a lot of criteria for a machine to be able to edit 4K(CPU single thread performance, GPU performance, Disk speed, etc.) Adding NVMe drive only improve the Read/Write speed of files into and out of the Mac, but not adding RAW processing power.

4. I still need this for 4K editing. So how?
If you really need it for 4K editing, you need to modify the MBP 15-inch 2012 as shown in the last clip in the video, with NVMe speed unlocked & X-GPU mod. Use the SATA SSD as your boot(MacOS), the NVMe is used for scratch disk/editing.

5. So why bother upgrading it to NVMe and all these hassles?
What we are showing here proves that these methods of extracting PCIe lanes are possible, and we can apply the same concept to all newer expensive and sophisticated Macs. Would you start this project with a 2000USD Machine? of course not. And it's really interesting to see what these old machines can still do after upgrading it with new hardwares.

6. Will this modification beats the M1 Macs?
Yes, and no. Depends on your perspective. Overall performance - in some areas yes, but overall of course not. Longevity and maintenance - nailed it!

Stay tuned for more interesting projects for your Mac! Hope you guys enjoyed this video, and thanks for watching!
