It’s time for the 2020 PPC Challenge!

The PPC Challenge has been around for a while. I don’t know who started it or where but I’ve been participating for at least 5 years. The goal is simple; For one week, use a PPC Mac for as much as your daily computing as possible. Last year I used a 17″ 800MHz G4 iMac and I got a remarkable amount of my daily computing done on it. Updating and maintaining my websites with Photoshop 6 and Dreamweaver MX, AppleWorks…

Power Mac G4 MDD Power Supply capacitor list (Samsung 360W)

Power Mac G4 MDD Power Supply capacitor list (Samsung 360W)

This project is a work in progress but I thought I’d share what I have so far. I finally set out to map the capacitors in an MDD PSU so that we can see about recapping it. Currently on my desk is a Samsung PSCF401601B(C) Rev: A & Rev: B 360W power supply. This came from a FW800 MDD and is a revised model, Apple shipped the first MDD’s with a 400W power supply that ran hot and was super…

Logic board repair, two years later

Logic board repair, two years later

Two years ago I wrote a bit about my beginning in the board repair industry. You can read all about that here. It’s not a thrilling read by any means but I know it has helped a few people out over the years, so I figured it’s time for an update. I am proud to say that I have repaired hundreds of boards and thus have saved people a LOT of money. Repairs that would have costed people up to…

Making a recovery and diagnostics drive

Making a recovery and diagnostics drive

One day, your Mac will stop working or experience some kind of issue. This may happen suddenly without warning and when it does, you want a recovery and diagnostics drive handy. This drive has to be external and must match the interface your Mac(s) offer. For example a FireWire (FW) drive is not going to do you any good for a MacBook Air. A PPC will not allow you to boot from an external USB drive (even on the G5…

Do I need malware protection?

Do I need malware protection?

This question pops up every other week in the various facebook groups and forums I’m in. And I cringe every time I see it pop up. Why? because the comments are abundant and are typically full of misinformation. I can write a 10 page article about this but I will try to keep it brief. Here are a few of my issues with common comments: 1. Product recommendations “I use ClamXav”, “Avast has never let me down!” “McAffee is the…

Tools I use – Prime95

Tools I use – Prime95

If you want to give a Mac a good stress test to see if the core components are up to snuff, Prime95 is (one of) the ways to go. It includes something called the “Torture Test” and it is as brutal as it sounds. Core 2 Duo or Xeon, Prime95 will put it to work like nothing else. It’s not just the CPU that’s tested, it’s the L1/L2/L3 caches, north bridge, RAM and all that connects those components together. Letting…

Tools I use – CoconutBattery & Watts

Tools I use – CoconutBattery & Watts

This is the first in a series called “Tools I use”. The idea is to cover a different tool every week or whenever time allows or the mood strikes. Some of these tools you may know, others you may not. I do not use affiliate links and do not get kick backs from any of the developers I mention in this series so you can be sure that any mention and recommendation I make is based on good first hand…

F.lux VS Night Shift

F.lux VS Night Shift

If you are not familiar with these terms, here’s a little history. History F.lux is an application that I’ve been using for as long as I can remember. I want to say 2005/2006 maybe when I started using it, an early iteration of it or an app that did something similar. The earliest reference I can find is from 2009 but I am confident I was using this (or something like it) long before that. Basically it filters out blue…

Mac Pro Pixlas Mod, is it really needed?

Mac Pro Pixlas Mod, is it really needed?

A few things have bothered me about the reasons for recommending the Pixlas Mod. 1. The mini 6-pin connector can only provide up to 75W of power. 2. The traces in the Mac Pro’s logic board are too thin to have more power demanded than 75W. I needed definitive proof (at least definitive for me) of these two claims so I decided to really dive into this. I’ve gathered all the relevant information and put the puzzle pieces together, along…

The iSchmutz is back!

The iSchmutz is back!

Years ago in 2013 I wrote about this awesome little Mac Pro dust filter called the iSchmutz. Unfortunately a few months after that Trans Intl. stopped selling them and I have been sending them emails for years asking if they have old stock, when it would be back in stock etc. The last reply I got was early 2018 saying they’d be in stock soon but as I had heard that a few times before, I was not holding my…
