OSX Sierra crash recovery

Well, that was unpleasant.

Without any warning, my Mac Pro began failing to redraw web pages. Presuming that Safari had become unstable, I commanded a reboot.

The reboot process got to 1/2 progress bar, then the machine shut down. Repeated several attempts, same results. Not just Safari then.

Time to recover. First I slapped a new HD in there, then used CMD-R (hold while powering up, keep holding until you get a dialog) to initiate recovery using the First Aid application from the original drive. The drive checked out okay as far as file integrity, but apparently (hopefully) the OS had developed some damaged boot settings. So. Time to recover to a new drive. I have a time machine backup on a different drive, but as it looked like the original drive was okay according to the tests the disk utility made on it, I decided to try to recover right from there. So off I went, installing OS X 10.12.6 on the new HD.

The dialog initially told me that 5 minutes were remaining. That stayed up for an hour without any visible changes in the progress bar. So I opened the log window (it’s in the Window menu of the first aid window) and saw that the progress value was at about .02%; 1% is complete (trust me, it’s not 100 as you would expect. .5% is halfway done.) It was changing, but very slowly. So I knew I had quite a wait ahead of me.

Twelve hours later, the install finally put up the OS X setup dialog. The progress bar dutifully moved from 5 minutes to 4, 3, 2, 1 and zero (Over 12 hours!?!?) as the percentage indicated in the install log window climbed towards 1%. I mean, come on. Really? I know Apple’s been lagging behind on software quality, but… really? This was over a 30 Mb DSL connection, btw. I can (maybe) understand the trickle rate of the download (Apple’s so poor they can’t afford a good connection, as all know) but the 5 minute indication… that’s just pitiful, shows a serious lack of QC.

Anyway… the recovery went well enough, if glacially, that the machine can be rebooted now, and it looks like most things are intact (not everything… recent file lists are clear, for instance) so I guess my griping can’t legitimately rise above some discontented mumbling.

It was a very unpleasant experience, though. If you have to reinstall Sierra, be aware that you can expect the dialog to bald-faced lie about the install time, and I suggest you open the log from the Window menu so you can see what actual progress is being made.

Some OS X DHCP Esoterica

Because I develop Software Defined Radio (SDR) software, I have occasion to connect, and disconnect, various network devices to my wired network in order to test them all day long. Most of the SDRs are designed to configure using DHCP, or can be convinced to do so. That saves some fooling around, and is a good thing. However, my network is extensive, devices are always being moved around, WiFi devices arriving and leaving, and so once the SDRs are assigned an IP, I have to go hunt them down. It was annoying that they’re always showing up somewhere different.

However, my Mac Pro had an unused second ethernet port sitting. right. there. Hmmm. So…

Why I Target OS X 10.6.8

OS X has come a long way since OS X 10.6.8; among the pluses: better multiple monitor handling, considerably improved memory management (part of which was fixing the leaks in the color management pipeline that OS X 10.6.8 exhibits) repairs to the bugs in 10.6.8′s CUPS printing system, and so on.

So why, then, target OS X 10.6.8?

Predicting where IOS and OS X will go

Every time I read one of the sycophantic articles predicting OS X is going to become like IOS, I have to laugh. That’s not going to happen, at least, not in the long term. So in the spirit of the new year, when every fool (I’m speaking most definitely of myself here) proceeds to stuff foot deep into mouth, I offer the following IOS, OS X, iPad and iPod predictions:

Python, TkInter, OSX (OS X) and making it all behave

I use Python a lot. Python 2.5.1 to be specific. And inside Python is TkInter, which, with a little work, will give you a handy way to put a GUI together. But there are problems. To say that TkInter is poorly supported and poorly documented under OSX is to understate the case rather dramatically. So you’re left to Google for answers, and mostly, they aren’t to be found — or if they are, they aren’t obvious or easily found. So I’m going to provide some answers here that have taken me quite some time to collect, and hopefully keyword and title them so that a Google search will actually get you to the solution you need sooner rather than as much later as it did me!

Using the Mac as a Guitar Workstation

I will start with a disclaimer: I am not in any way associated with the companies I’m going to mention here, other than being a paying customer for them.

Over my years as a professional musician, I’ve invested a phenomenal amount of money in musical gear. Amps, pedals, guitars, effects systems, you name it, I’ve probably bought it, beat it up, and traded it off in my search for “that sound.”

After about 40 years of playing, I’ve arrived at the combination of analog and digital gear that presently outfits my studio, and a few choice instruments. I was pretty happy with this too, except it isn’t very portable, and the setup is complex enough that there are times when I spend more time twiddling knobs than I do actually playing or recording.

Well, I’ve found something rather extraordinary. So much so I thought it was worth telling the world. As it turns out, there’s an easy, sensible, cool way to go that costs very little and gives you the world. Here’s the scoop.
