Always boot in verbose mode System
Holding down Cmd-V at startup will put MacOS X in "verbose" mode, displaying the Unix system message buffer instead of the Aqua splash screen and progress bar. For those who'd rather always boot in verbose mode (and don't want to hold down Cmd-V every time), the darwinfo.org FAQ explains how to set your Open Firmware parameters to support this.

Note that rebooting into MacOS 9 will reset these parameters, so this tip works only for as long as you stay pure. ;-)

Use Disk Utility to erase CD-RW discs System
I wondered for a long time how to erase a CD-RW with OS X. In fact, this is very simple (though I don't really like this method): it is done with Disk Utility (in Applications/Utilities).

I don't like it, because with this program, you can also erase any disk! I would have liked to create an Applescript to do it, but Disk Utility isn't scriptable...

[Editor's note: Although basic, this is one of the major changes with OS X. You no longer can erase a disk from the Finder - you must use Disk Utility. Keep this in mind when you look for "Erase..." in the Finder only to discover it's not there!]

Bypass the 30 sec delay with option-startup System
OK, so for some systems, it's possible to choose the startup partition holding the OPTION key at startup. Great! But, what is really annoying is the 30 second delay the Mac asks for each time I do a startup with OPTION key.

The other day, I started doing that, but at the same time I had my mouse button down, because I wanted to eject a CD I forgot to eject before shutting down. The CD ejected, and ... the usual partition dialog appeared without any delay!

So I verified again and again ... and it works! Pressing the mouse button while you press the OPTION key at startup brings the partition boot dialog instantaneously, with no delays!

Anyone else tried this? My machine is a 2000 iMac DVSE 500 slot-loading with OSX10.1 OS9.2.1 and 384mb of RAM...

Save 'unsavable' QuickTime movies System
MacFixIt's OS X Page published a tip today for saving "unsavable" QuickTime movies. QuickTime content producers have the option of indicating that a certain clip should not be savable, which disables the "Save" option normally available within QuickTime Pro. MacFixIt details the steps necessary to save a movie from IE using only GUI tools. Give it a read if you'd like a GUI method for saving QT clips.

On the other hand, you can also use the Terminal to accomplish the same result in fewer steps (although it can be argued whether it's easier or harder than the GUI method!). If you'd like to know how, read the rest of this article. NOTE: You'll need the Developer Tools installed for this to work.

Securely run remote AppleScripts System
normally with ssh you can run (on the command line) 'ssh machine command' to run a command on a remote machine. so put a compiled applescript called 'testscript' in your home directory and try and run it from a remote (or even the local) machine:
ssh yourmac testscript
and it will run that applescript. however, while that applescript shows up in the dock, it seems to have no access to running processes.

the trick is on the remote machine to run:
ssh yourmac 'open testscript'
the command above will instruct the running finder process to launch the applescript. see also the macosxhint Run an AppleScript from the command line and running applescripts via ssh? at macfixitforums.

for an example of a useful remote applescript (launch eudora and get new mail only when new mail exists), read the rest of the article.

Remove the 'Get Mac OS X Software' menu item System
A Co-worker noticed that the idea of having a link to buy MacOS X software right there in the Apple menu was very "Microsoftish", so he tracked down where it was located and I figured out how to get rid of the menu item altogether. (I know there are other links out there to customize (in a way) the Apple menu. This simply tells how to get rid of that menu item in X 10.1.)

Warning: If you're not comfy in the Terminal and/or vi, this might not be for you. An unsuccessful attempt at this has the nasty side-effect of not allowing you to run the Finder... (yes, you'd have to ssh/telnet into the machine to fix it if you mess this up somehow.)

[Editor's caution: I have not tried this myself, and it's quite possible that a mix-up in the editing will render your Finder unusable. Please proceed with caution if you're going to attempt this modification! Read the rest of the article for the how-to.]

Choose the screenshot image format System
You can set the type of image created by typing the following in Terminal:
defaults write NSGlobalDomain AppleScreenShotFormat [imageFormat]
where [imageFormat] can be JPEG, TIFF, PNG, or PICT (TIFF is the default). It's likely you'll have to logout/login to get the changes to take effect.

enjoy.

Print to many unsupported network printers System
If you have an unsupported, networked, non-PostScript printer, the instructions and files in this package MAY give you the ability to use it under OS X 10.1. The package walks you through some background on the Mac OS X printing system, the Darwin printing system, and installing GhostScript to get your non-PostScript printers working on your network. With a little bit of your own investigating, this package will potentially allow you to support your SERIAL printers, and possibly unsupported USB printers!

The hints and tips here will have potential applicability to any myriad of printing problems under OS X 10.1.

Potential fix for missing ATI Rage Pro drivers System
At present, Mac OS X does not accelerate the video on ATI Rage Pro chipsets. However, it appears the 10.1 CD contains at least a preliminary solution to the problem. On the MacFixIt Tips and Hints board, the RagePro Fix thread contains "Sysadmin's" hack for enabling ATI Rage Pro support. Basically, the hack involves taking some drivers that are on the 10.1 update CD and placing them on your boot partition.

If you have a Rage Pro machine (I don't, otherwise I'd try this for sure!) and would like to try this out, respond here with a comment as to the success or failure of the experiment. Obviously, you should have a good backup going in, because I would guess that Apple did NOT enable these drivers for a reason! However, the fact that they are even there is good news for Rage Pro owners -- it appears support is coming, at some point.

Permanent mouse speed-up System
Although I've previously published an article on Turbocharging Your Mouse", the method described in that article had problems - it didn't stick after a screensaver or USB hub switch, for example.

Carsten Klapp has addressed the problem in a much lower-level manner, by creating the AppleUSBMouse Turbo Edition kernel extension. Carsten modified the Darwin source code to greatly speed up the mouse tracking. His page details how he did this, and provides enough information for you to hack the file yourself, if you're so inclined and have the Dev Tools installed. The nice thing about the low-level solution is that it changes the actual default "slow" speed ... so even though I still have the problem of the mouse speed getting reset when I use my switchbox, it actually gets reset to a HIGHER speed than where I left it!

I'll probably tweak the driver a bit for my own tastes; the method of increasing the speed (by lowering the resolution) seems to make the mouse a bit jumpy. Still, this is a GREAT improvement over the stock settings. For fun, set your mouse speed slider all the way to the right and jump from screen edge to screen edge by just thinking about it!

This is a kernel extension, and theretically could do Bad Things to your computer. However, it doesn't replace any Apple parts, it merely sits on top of them. Also, I've been running it for a few days with no ill effects (other than a reset of my 'uptime' after the first install - you have to restart to get the new extension to load over the default one). If you do have a problem, simply delete the installed extension and reboot (instructions are on Carsten's page).

The beauty of open-source -- if you don't like something and you've got the skills, you can change it!
