10.6: Another way to lock your screen System 10.6
Snow Leopard only hintSecurity is a requirement at my workplace, and I noticed all my Windows using colleagues quickly lock their screens with a key combination before getting up to leave their desks. When they return, they need their username and password to resume their working session. There are multiple ways to lock your screen on the Mac, but this one takes the cake for me, as it mimics the same easy get-up-and-go process Windows users enjoy.

The first step to this hint is to configure your Mac to require a password to wake from sleep of screensaver. You can enable this setting in System Preferences in the Security control panel. Once there, choose the General options tab and check the box to 'Require password x minutes after sleep or screen saver begins.' Set the variable time to immediately require a password.

At this point, you may want to take some time to review and adjust your Screen Saver settings, and your Energy Saver settings, as this security option will also be triggered when just your display goes to sleep normally.

Quit System Preferences and you're ready for the final piece of this hint.

Next time you get up from your Mac to run to a meeting or the bathroom or whatever, fire off this keyboard combination:

Control+Shift+Eject

This is actually a shortcut to sleep your computer display, but now has the side effect of locking your screen and requiring a password to resume your session.

[crarko adds: I tested this, and it works as described. It's basically a variation of this previous hint, but has the advantage of using a default keyboard sequence. There's a number of ways that have been offered to do the screen locking, and this hint is another alternative.]

10.6: A New Service to Shorten URLs System 10.6
Snow Leopard only hintI submitted a hint a while ago, regarding a way to create short URLs using Perl, AppleScript and Automator, which also required that one download a package of software.

Since that hint was published, the URL service (qgf.in) went down because the owner left it to the wolves. So here's a new Service that completely eliminates the need for Perl and the download. This service uses bit.ly, but you can choose another website (make sure you get the API format [usually http://short.url/api?url=http://website.com/]) as well.

10.6: Fix sleep problems with SleepWatcher System 10.6
Snow Leopard only hintI built a customized Mac and was very happy with it, until I realized that it wouldn't automatically go to sleep regardless of my Energy Saver settings in System Preferences.

I did some research online and noticed that many people with real Macs were having similar issues (in my case it's because of the DVD drive), and then I found this site with a link to SleepWatcher; a very good utility!

Unfortunately, all the hints mentioned here either did not work for me, were incomplete, needed some other utility to work, or had an outdated method for launching.

So I've detailed the steps below to make it work system wide (and no it won't go to sleep if you're watching a movie) and hope it'll help those of you who have an insomniac Mac for whatever reason.

10.6: Zoom and pan images in column view System 10.6
Snow Leopard only hintWhen using Column View in the Finder, holding the Option key while clicking the preview of an image will zoom the image. Holding Shift-Option while clicking zooms out the image.

Click and drag in a zoomed image pans the image. I discovered this by accident when holding the option key while dragging the preview image during a copy. I mistimed the keypress and mouse click and instead zoomed the image.

[crarko adds: I tested this, and it works as described. This appears to be Snow Leopard only.]

10.6: Free native read of HFS+ disks in Windows System 10.6
Snow Leopard only hintHere is a solid, free solution to reading HFS+ formatted discs in Windows OS using only the Snow Leopard install disc. The nice thing is that the Windows install doesn't have to be 'real' Boot Camp.

Inside Windows:
  • Load up the Snow Leopard disk.
  • Ignore Autoplay.
  • Navigate to Boot Camp » Drivers » Apple » Bootcamp.msi.
    (Note: please choose Bootcamp64.msi if you're running 64 bit Windows).
  • Follow the installer instructions.
  • Restart.
  • Using Start » Run » msconfig, disable 'Boot Camp' from running at start up.
  • Restart again.
You should now see your HFS+ partitions of external or internal drives. Tested on a Windows 7 laptop (non Boot Camp).

[crarko adds: I haven't tested this one.]

10.6: Update renders Mac with PGP disk encryption unbootable System 10.6
Snow Leopard only hint10.6.4 users running PGP Whole Disk Encryption may render their systems unbootable after they update to 10.6.5.

PGP recommends folks to decrypt their drives first, update to 10.6.5 and then re-encrypt. If you have already upgraded and have an unbootable system, burn/use a copy of their Recovery CD to fix. I can verify that using the Recovery CD works.

Procedure:
  • Boot the system using the PGP Recovery CD.
  • When prompted, authenticate with your passphrase. DO NOT press D to decrypt. Press any key (e.g. spacebar) to boot into Mac OS X normally.
  • Once logged into Mac OS X, PGP Desktop will automatically fix the boot issue and you should no longer need the recovery CD.
  • Download the script 'PGPwdeEFIUpdate.sh' to your desktop
  • Open terminal and navigate to your desktop directory by typing cd ~/Desktop and pressing Enter.
  • Type in the command chmod 755 PGPwdeEFIUpdate.sh and press Enter.
  • Type in the command sudo ./PGPwdeEFIUpdate.sh and press Enter.
PGP has a tech article about it, and that is the source of this procedure. You can download both the ISO for the recovery CD and the referenced script from links provided there.

[crarko adds: I haven't tested this one.]

10.6: Re-Enable GrowlMail in Mail 4.4 System 10.6
Snow Leopard only hintIt seems like, with every new version of 10.6.x, GrowlMail gets disabled by Mail.app. Sure enough, this has happened again with 10.6.5 and Mail 4.4.

Rather than wait until someone posts a patch to get it working again, I figured I'd find out what needs to be done, and how to do it.

Thanks to Paul Kehrer's previous posts, which have been summarized in this previous hint, it is possible to fix this using a slightly different process. This method should continue to work for future revisions as well, at least with Snow Leopard.

10.6: A PDF Compression Service System 10.6
Snow Leopard only hintThis is a followup to this thread about using a Third party Java tool for PDF compression. I didn't get successful font rendering for the compressed PDF file using the included command options for tool.pdf.Compress, so I left the '-noembed' option out, but you can use your own command options as also described in a comment to that earlier hint by changing them in step 23 of the Workflow. This Workflow is long but it demonstrates a technique I sometimes use for building and executing shell commands.

10.6: Run old screen savers on Snow Leopard System 10.6
Snow Leopard only hintWith Snow Leopard the ScreenSaverEngine application is a 32/64-bit binary, and if your system supports it will run in 64-bit mode. This means that any screen savers without 64-bit code will not run, and this is primarily old unsupported screen savers.

To get screen savers with only 32-bit code in them to run ScreenSaverEngine must be forced to run in 32-bit mode only.

10.6: Unlock screens using any admin password System 10.6
Snow Leopard only hintMac OS X 10.6 tightened security and now one administrator user cannot unlock the screensaver of another admin user. However, many IT professionals need to be able to grant their users admin access to their Macs while still being able to effectively administer the machine in their absence.

Visiting a users machine to resolve a help desk ticket is frustrating if that users screen is locked and the user has left for the day, is out to lunch, in a meeting, etc.

To enable an admin to unlock another admins screensaver you simply edit a file on the machine, edit the file: /etc/pam.d/screensaver, changing

account required pam_group.so no_warn group=admin,wheel fail_safe
to
account sufficient pam_group.so no_warn group=admin,wheel fail_safe

You'll need to use a text editor capable of modifying and saving system files; e.g. any CLI editor used with sudo, or a GUI editor like TextWrangler if done in advance. It is not necessary to log out or restart. In fact if you visit a machine that is locked in this way and have SSH access to it you can modify this file and then unlock the screensaver using your admin account.
