Permanently Disabling 2011 MacBook Pro 15" Dedicated GPU - Custom gMux Firmware Flashing Overview
 
11:12
All info and resources needed for flashing yourself can be found here: https://computeco.de/Demux In this video, I go over the process of disabling the defective AMD Radeon HD 6xxx series video card in a 2011 15" Apple MacBook Pro, using a custom gMux IC firmware that I've developed. This modification is, of course, 100% permanent, and does not rely on any NVRAM variables being set. This also drastically decreases the amount of time and skill previously needed to perform the other, hardware-based gMux IC bypass modifications.

How to Install macOS Sierra on an Unsupported Mac
 
12:02
In this video, I go over the steps needed to install macOS Sierra on an unsupported Mac. The whole process is based around the macOS Sierra Patch Tool for Unsupported Macs, which is a program I wrote to allow all users to easily perform the necessary modifications. The download, instructions, and all necessary resources are available on my website here: http://dosdude1.com/sierrapatch.html The macOS Sierra Installer can be downloaded from here: https://drive.google.com/open?id=0BwMVdS23k_J-bXZfaE9zSGpJN2c Issues that are still being worked out: -Unsupported WiFi modules in some systems. Macs that use the Broadcom BCM4321 WiFi module will not have functional WiFi when running Sierra. A fix for this is to open up your machine and install a compatible WiFi card. Machines affected include some MacPro3,1, MacBook5,2, MacBookPro4,1, iMac8,1, Macmini3,1, and MacBookAir2,1 systems. Please note that not all these machines will have an unsupported card, this is just a list of machines known to have shipped with that card in some configurations. -Trackpad (MacBook5,2 affected only). The trackpad in the MacBook5,2 isn't fully supported in Sierra. While it works and is fully usable, Sierra detects it as just a standard mouse, preventing you from changing some trackpad-oriented settings. -Audio issue (iMac8,1 affected only). On some iMac8,1 systems, the audio volume doesn't seem to change even when the system indicates that it is. The audio is still usable, however it will remain at maximum volume all the time.

Repairing a Mid-2010 15" MacBook Pro that Kernel Panics when Using the Dedicated GPU
 
15:37
In this video, I go over a very common issue with the Mid-2010 15" and 17" MacBook Pros with the nVidia GeForce GT 330M dedicated video card. Essentially, what happens to these systems is a capacitor on the GPU framebuffer power rail fails, and starts to pull the rail low. When this happens, it will cause the machine to kernel panic when switching to or running off the dedicated video card, and in some cases can simply cause no image to appear on the LCD at all. In this video, I go over the process of replacing this faulty, undersized capacitor with one of the same specifications that is much larger, preventing this issue from ever happening again in the future.

Late-2009 Mac Mini Socketed CPU Upgrade
 
20:24
In this video, I go over the process of replacing the original BGA Core 2 Duo CPU in a Late-2009 Apple Mac Mini with a CPU socket, and upgrading the machine to a 3.06 GHz Core 2 Duo T9900. My only concern when starting this project was that the original CPU heatsink may not fit on properly, but to my surprise, it ended up fitting on just fine without having to modify it at all. With a CPU socket now installed, this machine is now the first fully upgradeable Late-2009 Mac Mini! This mod and upgrade was done to one of Greg Hrutkay's machines.

macOS 10.14 Mojave Beta Running on Unsupported Macs
 
12:21
In this video, I demonstrate macOS 10.14 (Mojave) Public Beta running on various unsupported Macs. As of now, Mojave works almost perfectly on most recently dropped machines, but does have a few minor issues. The main issue at this point is the lack of graphics acceleration on machines with pre-Metal AMD/ATI video cards, but hopefully a solution will be found in the future. Pre-Metal Intel HD Graphics and nVidia GPUs work pretty much perfectly, though. If you'd like to give it a try for testing on your machine, you can download and run my Mojave Patcher tool found here: http://dosdude1.com/mojave Please note that it is recommended that you run Mojave on these machine for testing only, and not as your main OS. Do not expect everything to work perfectly at this time.

Replacing a Defective GPU on an Early-2008 15" Apple MacBook Pro
 
22:09
In this video, I go over the process of replacing a defective nVidia GeForce 8600M GT video chipset on an Early-2008 15" Apple MacBook Pro pre-Unibody. This failure is VERY common with these machines, and is due to a manufacturing defect with the original variants of the 8600M GT chipset (G84-602-A2). In 2010, nVidia released a revised version of the chip (G84-603-A2), which doesn't have this issue, and is insanely reliable. Apple began putting these new chips in machines brought in for service in 2010 and later. Replacing a defective G84 GPU chip with a revised version will make the machine 100% immune to future GPU failures.

Permanently Disabling the Defective GPU on a 2011 15" MacBook Pro - Hardware Mod Overview
 
16:14
In this video, I go over a very involved and tedious modification I performed to permanently disable the defective dedicated AMD video card on a Late-2011 15" Apple MacBook Pro. This mod involves desoldering and removing the gMux chip (which handles the dynamic GPU switching on these systems), and hard-wire the LVDS output lines of the integrated graphics (Intel HD Graphics 3000) to the lines going to the LVDS connector. It took quite a bit of patience and quite a few bodge wires, but the end result was a fully working system! I also ended up having to flash the system to MacBookPro8,1 (2011 13") firmware, as graphics acceleration wouldn't work with the stock 8,2 firmware for some reason. The only things that don't work with this mod as of now are the brightness control, and the external display port. Other than that, though, everything works great! Wiring diagram s and more details can be found on my MacRumors thread here: https://forums.macrumors.com/threads/permanently-disable-2011-15-17-macbook-pro-dedicated-gpu-gmux-ic-bypass.2134019/

Macintosh SE on dial-up Internet
 
11:57
This is a demonstration of my Macintosh SE accessing the Internet using a dial-up modem and doing some very simple Internet tasks. The programs used to accomplish this are the MacPPP package (the extensions needed to use Internet on System 6), MacWWW (for doing very simple web browsing), and Ircle (an IRC client). You can download all of these files in .SIT format here: http://dosdude1.com/files/macstuff/classicmacos/macintoshinternet/ (Please remember these are System 6 programs... Much better programs exist for System 7, however MacPPP is System 7 compatible as well.) The modem used is a Global Village Teleport/Bronze model A861, which is designed for a Macintosh Performa, however it seems to work just fine on my Macintosh SE. It's only 2400 baud, so it's pretty slow, and makes a strange initialization sound. Link to DJComputerguy's channel: https://www.youtube.com/user/thepcamdmacintoshguy

11:45
In this video, I go over the process of downgrading an original iPhone from iOS 3.1.3 to iPhone OS 1.0. Keep in mind this doesn't work on some newer production original iPhones, but should work with most. All software shown in the video is available for download here: http://dosdude1.com/files/iphone2gdowngrade/

macOS Sierra Developer Preview 10.12 Running on an Unsupported Mac
 
08:48
This is a demonstration/proof-of-concept of macOS Sierra 10.12 running on an unsupported Mid-2009 MacBook, as well as a Late-2008 MacBook Air. It works almost perfectly fine on both machines, with the exception of WiFi on the MacBook Air (which should be an easy fix). It actually runs surprisingly well on these unsupported machines. You can find the thread at http://forums.macrumors.com/threads/macos-10-12-sierra-unsupported-macs-thread.1977128/ if you're interested.

09:25
In this video, I give you an overview of a large collection of vintage Apple Macintosh computers I recently purchased off Craigslist, all for $160. All the machines I got should be repairable (and most are already fully functional), except for a Macintosh SE/30 that had an unfortunate PRAM battery leak, which destroyed the logic board. The machines I got include: - 2 Macintosh SE/30s - A Macintosh SE with SE/30 motherboard - A Macintosh Plus - A Performa 6300CD - A Macintosh IIsi - A desktop beige PowerMac G3 - A Macintosh LC - A Macintosh LC II - A PowerMac 6100 DOS Compatible - A PowerMac 6500 - A Macintosh LC 580 all-in-one - A PowerBook 5300CS - 2 Apple CRT monitors

G4 Upgraded iBook G3 Clamshell Overview
 
12:50
In this video, I go over the process of modding and demonstrate an Apple iBook G3 Clamshell, that has been upgraded to a PowerPC G4 (7410) CPU. This modification is quite involved, and requires desoldering and replacing the original PowerPC G3 (750) CPU with a G4. With the G4 CPU installed, extra cooling is needed to allow the CPU to run at a normal temperature, since the G4 runs much hotter than the G3 originally did. With the G4 installed, the system runs quite a bit faster, and is now able to boot and run Mac OS X 10.5, Leopard. I performed this mod for Greg Hrutkay from the Hrutkay Mods YouTube channel, who I suggest you check out here: https://www.youtube.com/user/HrutkayMods

Late-2008 13" Aluminum Unibody MacBook Backlight Repair
 
13:25
In this video, I go over the repair of a Late-2008 Aluminum Unibody MacBook logic board (820-2327) that would not produce a backlight on an LCD panel. I repaired this board for a friend of mine, who you can find on Twitter here: https://twitter.com/alitek123 The solution ended up being relatively simple, as the issue turned out to simply be a bad trace somewhere in the board. I soldered on a jumper wire where the trace was supposed to connect to, and that got the backlight to function perfectly once again.

17" Apple MacBook Pro Model A1229 Repair
 
14:20
This is a repair overview of a 2007 17" MacBook Pro, model A1229. I got this machine off eBay for $35, and it was in non-working condition. It turned out to have two issues. The first and main issue was that the nVidia GeForce 8600M GT GPU had failed, which I repaired by reflowing it with a heat gun. After doing that, however, I found that the LCD backlight didn't work. This turned out to be caused by a bad inverter, as well as a blown backlight fuse on the logic board. I replaced the inverter with one I had spare, and simply jumped the fuse with a piece of wire. While not the best idea, it's been working perfectly so far. Repair of the 15" Model: https://www.youtube.com/watch?v=A6agjL18da4
