Even though OS X is a pleasure to work with, we have all had a program or process freeze up. It won’t quit by using “Force quit”. What do you do now? Fortunately, this can be solved quite easily. To kill program Mac OS X terminal on Leopard / Snow leopard / Lion do the following commands:

Apple OS X 64-bit Application [email protected] KillDisk for Mac is an easy-to use & compact freeware utility that allows to sanitize attached media storage with the 24 international data sanitizing standards. It permanently erases all data on Hard Disks, Solid State Drives, Memory Cards & USB drives, SCSI storage & RAID disk arrays. You can access the Force Quit dialog box by pressing ⌘ + ⌥ + esc, or using the Apple Menu (top left corner of the screen) and choosing Force Quit. Select the problem app, and click the Force Quit button. You can also kill an app using the command line (/Applications/Utilities/Terminal). Xkill typically wouldn't delete files - it only terminates a process.You may have ran xkill on your file manager window, which would have terminated the file manager (you can always start it again, this is temporary) but it would not have deleted any files. Just to clarify, a file manager is a program that lets you view your files, often graphically (as opposed to doing it in the terminal. TenFourFox is a distribution of Mozilla’s Firefox browser compatible with Mac OS X 10.4 and 10.5 and optimized for the G3, G4 and G5 processor families. Downloading it and running it is quick and easy, no more complicated than installing Firefox on a modern Mac OS computer. Everything seems to work, although speed is quite often an issue.

Kill the program

This will give you the number of the processes found (if any). Now just close them with this command

So, for example to kill my activity monitor program

Now the offending program will shut down immediately, no matter what it was doing. This is, however, a last resort. You will lose any unsaved changes.

What happens behind the scenes when you kill the program is a bit different from regular operations. Normally, the operating system asks the program nicely to go away. With the above kill command, it simply shuts it down immediately without asking or telling it anything. There you go. Gone.

Has this post got you interested? Would you like to learn how to do more interesting stuff in OS X’s terminal , than just kill a program. Then read these 10 commands. Even more interested? The OS X terminal is built on top of bash, and you can read more about it in this tutorial.

I’ve been asked to keep some stuff for a friend who’s moving into a new house,including an old Apple iMac G5 that is destined to end up in the bin.

Produced from 2004 to 2006, the iMac G5 is the final iMac to use a PowerPC processor. The PowerPC architecture has since become niche in the desktop market, although it still retains significant popularity in the embedded and high-performance markets.

Due to Apple’s transition to Intel processors in 2006, the most recent release of Mac OS that maintains compatiblity with the iMac G5 is 2007’s Mac OS X 10.5 Leopard. Indeed, this is what my friend’s machine is running.

Although fundamentally outdated, I can’t help but feel a little uneasy aboutdiscarding a perfectly working and relatively modern computer. The iMac G5’sLCD panel, for example, is excellent and vastly superior to many of today’s low-budget screens, at least to my eyes. Moreover, as clearly shown by what MorphOS can achieve on even older Mac Mini G4 models (including playing 720pHTML5 video!), the hardware of the iMac G5 is definitely capable of supporting basic daily usage.

However, I’ve had little luck in my attempts to breathe new life into this machine. The main reason is the lack of a modern browser to explore the web oftoday, which is vastly more complex and computationally expensive than that of 2005. My initial goal was to get the iMac to stream HTML5 video, which I find to be a good general indicator of a machine’s compatibility with modern times. So far I’ve tried what follows, without success.

TenFourFox is a distribution ofMozilla’s Firefox browser compatible with Mac OS X 10.4 and 10.5 and optimizedfor the G3, G4 and G5 processor families.

Downloading it and running it is quick and easy, no more complicated than installing Firefox on a modern Mac OS computer. Everything seems to work, although speed is quite often an issue. YouTube video, even at 360p, is stuttery to the point of being unwatchable.



Lubuntu is a lightweight Linux distribution based on the more famous Ubuntu. It is one of a dwindling number of Linux distributions that still releases images and maintains packages for the PowerPC architecture.

Booting Lubuntu from the live .ISO image was simply a matter of dding the image onto a USB stick, launching the Open Firmware bootloader (by pressing CMD+OPT+o+f during the iMac’s boot sequence) and entering command boot usb1/[email protected]:2,yaboot.

Once booted, Lubuntu appears reasonably fast. However, navigating to YouTube using Firefox resulted in the browser crashing irreparably, having to be terminated using xkill or any other variant of kill -SIGKILL.


MorphOS is a proprietary operative system forthe Amiga and other PowerPC-based personal computers. MorphOS 2.4 added support for Apple’s Mac Mini G4 in 2009 while MorphOS 3.2 added support for Apple’s PowerMac G5 in 2013. MorphOS’ OWB browser, although last updated in 2014 and seemingly discontinued, is based on the ubiquitous WebKit rendering engine and seems to support many of the features of today’s web.

Unfortunately, I could not get MorphOS to boot. I tried booting into it usingboth a CD and a USB stick as per the official guides but none of these worked. The former resulted in a black screen that left me wondering whether I had stumbled into a boot issue or merely a graphical one. The latter resulted in the boot error unrecognised Client Program format, for which I was unable to find a solution.


I am sure that each of these three alternatives could do with spending more time tweaking and tuning the small details. I am satisfied with the amount of hours I have put on this weekend project, however, and I do not plan on putting more on it. I am a little saddened that the pace and direction of technological change make reviving such a recent machine (in human scale) so counter economical. I wonder where we are heading. How many perfectly functional machines are we throwing away? How much needless waste are we producing?
