Many users around the net have been realizing after installing the OS X Yosemite beta the partitions on their hard drive were converted to Logical Volumes. I’m not entirely sure why Apple chose to do this, but it makes resizing and deleting partitions on the fly 10x harder! I haven’t found a good solution as of this writing, but make sure you are aware of this!
Apple introduced “Core Storage” with the release of OS X 10.7 Lion. All Fusion drives use Core Storage. A Fusion drive is pretty much just an SSD and traditional spinning hard drive combined into one logical drive. Normally these drives would show up separately, but with the help of Core Storage, they can be turned into one logical volume. It’s possible to create your own Fusion Drive with a separate SSD and HDD by using Core Storage. There are a few tutorials around the web that can help with this. I’ve created 3 of my own “Fusion Drives” using these guides.
Some people have ran into a problem with creating a bootable USB installer for the Yosemite Beta. The script located in the Installer app called “createinstallmedia” does not work quite yet on Yosemite like it did in Mavericks. I kept getting an error that told me my volume wasn’t a valid mount point.
After doing some research, I came across a post on MacRumors.com that had a workaround. Just run the following commands in Terminal and you’ll be good to go!
This little guy came into work the other day. This machine is probably one of the coolest that Apple has ever made! Brand new they costed $7500!! And even today, this collector’s item is selling for anywhere between the $1000-$2000+ ballpark. It’s amazing that something so old can still keep it’s value. Here’s an excerpt from the description over at everymac.com:
The unique Apple 20th Anniversary Macintosh, based on an internal design similar to the Gazelle architecture, features a 250 MHz PowerPC 603e processor, 32 MB of RAM, a 2.0 GB hard drive, a vertically oriented 4X CD-ROM drive, an ATI 3D RAGE II graphics processor with 2 MB of SGRAM, S-video input, TV/FM Radio capability, and a custom Bose speaker system all packed in a custom, one-of-a-kind case.
The 20th Anniversary Mac shipped with a unique keyboard with an integrated trackpad and Italian leather palm rest as well as a large external Bose subwoofer.
I won’t lie, when I first saw this machine I geeked out pretty bad. This is the first one that I had ever seen in person! A couple coworkers and I decided to test out the Bose speakers. After all, Bose is one of the best right? We downloaded iTunes 2.0.4 from macintoshgarden.org and popped in a CD and played some tunes! I was quite impressed with the sound quality coming from the 17 year old speakers!
This particular machine had been maxed out all the way with the processor upgraded to a 500MHz G3 and RAM maxed out at 128MB! All in all, this machine is cool enough to make anyone’s head turn.
I received the new processors and put them in about a week ago. They work great! Temps are a lot more normal. There is still a slight difference in temps between the two processors but that is expected.
I’m positive the temps will go down with time. I read this article from someone who upgraded to the exact same processors as me. He states that his temps went down after a couple months. Apparently thermal paste needs to be “broken in”. It makes sense but I’d never heard of it before.
Also, I upgraded the firmware from the 2006 (MacPro1,1) to the 2007 (MacPro2,1) using a utility found on netkas.org. This allows the “About This Mac” box to show “2x 2.66 GHz Quad-Core Intel Xeon” instead of showing “2x 2.66GHz Unknown” for the processor specs. **EDIT:** You can download the utility from here.
I took the liberty to encode a Blu-Ray movie to H.264. It worked fantastic! Temps were in the 80°C. It was a lot better than the last time I tried with the old processors! (Last time temps shot up to 100°C and the fans were going at full blast. It sounded like a jet taking off!!). I was very pleased with the encoding speed. On my previous Quad-Core Hackintosh, 1080p would encode at about 6 fps. This was encoding at about 24 fps!! That is amazing in comparison to my Quad-Core i7 Retina MacBook Pro that gets about 27 to 28 fps!
All in all, this 2006 (now converted to 2007) Mac Pro was well worth it in terms of performance and price.
So it turns out, the processors I bought weren’t correctly matched. One would consistently run about 10 C hotter than the other one. Luckily, the guy I bought them from on eBay was able to exchange them for me. (Don’t worry, I gave him good feedback!).
I should be able to put the new processors in this weekend sometime. Stay tuned for an update!
Recently, I had an original Mac Pro fall into my hands. It’s the Quad-Core 3Ghz model. It’s not a bad machine for being free! The interesting thing is that this old Mac Pro geekbenched higher than my Hackintosh that I made a few years ago. So I figured it was time to scrap the hackintosh and go with the real Mac!
The only caveat is that the original Mac Pro doesn’t “officially” support OS X Mavericks. However, with the help of some people over on forums of MacRumors.com I was able to get it installed. I needed to upgrade the graphics card though since Mavericks doesn’t support the GeForce 7300GT that came with the original Mac Pro. Luckily I had an old PC GeForce 8800GTS that works just fine in the Mac Pro (as long as you’re running Lion or higher!).
One problem with this free Mac Pro was that it was missing the memory card cage and rear fan. I purchased one of those off eBay for $20. For the mean time I had to hold the memory riser cards up by using so electrical tape (see picture below). I wanted to get some extra performance out of this Mac Pro to put it in a closer category with my 2.6Ghz i7 Retina MacBook Pro so, naturally, upgrading the processors seemed like a great idea! Apple released an 8-core version of the original Mac Pro and dubbed it the MacPro2,1 (as opposed to the MacPro1,1). This official 8-core version used two 3Ghz Quad-Core Intel Xeon X5365’s.
Looking on eBay, the only X5365’s were close to $200! Most were being advertised as an upgrade kit for the original Mac Pro. I decided to look at some similar processors and settled on the Xeon X5355. This processor is literally the exact same as the X5365 but runs at the lower clock speed of 2.66Ghz. I found a matched pair on eBay for $60! So I purchased them, along with some Arctic Silver 5 thermal paste and 16GB of DDR2 RAM for $25 at the local computer shop. The upgrade process went smoothly!!
Here’s the upgrade process in pictures:
The new geekbench score blew the old one out of the water! All in all, even though this Mac Pro is close 8 years old now, it still is a very fast machine!! I’m excited to try and rip some of my blu-ray movies for the Apple TV!
UPDATE: CPU1 is running about 15 – 20 C higher than CPU2… I might need to reapply thermal paste to one of the processors. It could also be that I didn’t tighten down the heatsink enough. I will fix it and let y’all know the results!
