Happily ploughing through my email inbox this morning, trying to get on top of things, when suddenly, the Mac Pro "kernel panicked". To the uninitiated, or to those who still think Macs don't crash, this is the equivalent of the Windows "Blue Screen of Death" on a Mac, albeit handled much more elegantly by a slowly rising curtain of darkness with a multilingual message displayed centre screen.
Anyhow, it means the whole Mac has crashed and you need to power down and power back up.
Since getting a Mac 5 or 6 years ago, this has happened six or seven times on various machines and usually a reboot fixes things.
Except this time...
The Mac Pro would not boot.
Not "pining for the fjords" or simply "stunned", it was a true "Norwegian Blue".
No chimes, just a laboured sound of a fan spinning up and down again in a cycle.
Oh dear!
Baring in mind this was my main production machine, an icy chill ran down my spine when I realised the severity of the problem.
Luckily, this only lasted for a second or two as I had a contingency plan.
Back when the Nehalem Mac Pros came out (you know, the ludicrously expensive ones), my local Apple store contacted me to see if I'd be interested in one of the pre-Nehalem Mac Pros at a knock down price. To cut a long story short, I said yes! The main idea was that I could use two Mac Pros as a distributed encoding system but to be honest, due to the flakyness of Compressor, this never really worked out. The second reason was to have a backup machine, you know, just in case I ever had a problem with my main production machine.
Like today!
So within 5 minutes of the problem, I had both Mac Pros disconnected and next to one another.
A single flick of the lock both side panels were off.
Pulled 4 drives out of each machine and swapped them over - no tools required
Removed the Expansion Card holder in each machine (4 screws)
Moved my CompressHD card and MX02 card from the production machine to the Spare and replaced the gard holder.
Panels back on and reconnect.
Within 15 minutes I had the spare Mac pRo back up and running with the identical configuration as before and I'm back in business.
The "spare" Mac Pro was being used by my wife so in order to keep her working, I took the boot drive from the spare Mac Pro and inserted it into the Voyager Quad Interface and connected it to my old 17" MacBook Pro via Firewire. Chose the external drive as the boot drive and she's working away exactly the same as before.
All that is left is for me to battle through the snow to take this Mac Pro back to the Apple store for repair. Wish that Apple did a home repair service - I'd pay for that.
So my folly of buying a second Mac Pro has now been completely justified and it's a huge relief to know I can carry on regardless.
As an aside, the ease at which you can transport drives between machines and how OSX can boot machines with external drives without the slightest hiccup is one of the most impressive features of using Macs, especially when comparing the nightmare of trying to boot a mixture of Windows machines. It just makes it so easy to support and should be one of the reasons why businesses and corporates should take Macs more seriously.
The Mac Pro is now safely back from the repair shop. It seems they needed to replace the logic board.
