How to fix the ARD toolbar buttons/functions missing from Screen Sharing under OS X 10.5.5

September 18, 2008 1 comment

I’d like to thank a couple of my readers for telling me how to remedy the problem of the ARD Screen Sharing toolbar function hack that can no longer be applied once one upgrades to OS X 10.5.5.

The solution is glaringly obvious and I’m a bit annoyed I didn’t spot it myself.

Just use Time Machine and search for the Screen Sharing application, located in /System/Library/CoreServices/Screen and return to an older version of the app!

You gotta love Apple for handing you the solution on a plate.

Alternatively, dig out your Leopard DVD and pull it off there.

You’ll apparently get bugged by an upgrade screen.

I had read that Apple were trying to cut down on “Frankenbuilds” using software from different versions of the OS, but I guess this is still OK.

I’d like to try this, but since I have a nice, fully functional ARD 3.2 installed there’s not much point for me!

Still, I may try it one day. Let me know how you get on with these tips.

Tech Tip: WordPress 2.5 comments awaiting approval don’t appear in admin panel

June 24, 2008 1 comment

If you find that comments awaiting moderation are not showing up in the admin panel of WordPress 2.5.x then you need the following fix to be applied to your WordPress database.

Use PHPMyAdmin or another too to connect to your WordPress database and issue the following SQL command:

create index comment_date_gmt on wp_comments(comment_date_gmt);

You should find that comments now display correctly in the admin panel.

OS X 10.5.3 Update breaks Time Machine backup with “cannot mount volume” error

May 30, 2008 Leave a comment

I am using Leopard Server and was happily backing up to a Leopard Client. (Yes, my server is backing up to a Firewire mounted external volume on an OS X client machine, shared over ethernet with AFP!!)

After months of trouble free operation, I upgraded both to 10.5.3 and got the “cannot mount volume” error.

I tried several times, but it would time out with an exclamation mark icon after a few minutes, each time.

  • I switched off Time Machine
  • Disabled file sharing on the client
  • Reset the Client
  • Switched AFP sharing back on
  • Manually mounted the .sparsebundle once on the server – It mounted fine.
  • I then reenabled Time Machine, ran the “backup now” option.

In my case, the above steps fixed the problem. I now have hourly backups working again.

Automatic Update of Death

May 29, 2008 Leave a comment

I get to work this morning to find all the documents I was working on and websites I’d visited to research them closed and gone.

It seems my computer had crashed during the night.

So I log in only to get a cute little error message in the corner of the screen.


I don’t care if you were trying to be helpful, Microsoft. This is MY computer!

I really hate it when a corporation thinks it’s smarter than you are and pulls your control from under your feet like an old rug!

Basically, they might as well have said this:



Windows seems to do that a lot, taking fate into its own inept hands and misinforming the poor suckers who have to make do with it. Misinforming you say? Surely not. That error message is clearly written in language suitable for the primary audience, Americans.

Well, let’s just see what we have:

Your computer was recently updated!

Ok, I have no complaints so far… A surprisingly lucid comment.

Windows recently downloaded and installed an important security 
update to help protect your computer.

That’s very kind, thank you. So far so good.

The update required an automatic restart of your computer.

I beg your pardon?

The update required an automatic restart of your computer.

Required an automatic restart? Are you absolutely sure about that? Are you quite perfectly sure that had I restarted the computer myself, it would not have installed?


In haiku then, what the message is really saying is this:

I have decided
to reset myself without
the slightest warning.

There is a fix available for XP Professional Users:

  • Run “gpedit.msc” from the Start Menu (execute file)
  • In the Group Policy editor navigate to:
  • Computer Configuration / Administrative Template / Windows Components / Windows Update
  • Double click on
  • No auto-restart for scheduled Automatic Updates installations
  • Choose “Enabled” in the settings window
  • Click OK
  • Close the Group Policy Editor
Never used it myself, but if You’re an XP Home user, apparently you’re up the long brown one with out the long wooden one.

Installing old ATI Rage Pro 128 video drivers from Tiger into Leopard on G4 Cube

May 14, 2008 4 comments

Seeing the graphics benchmark results for Leopard being so slow, I got to wondering if it was the drivers which were affecting the performance. Perhaps the old ATI was unrecognised by Leopard.

First I checked the system profile on the Apple menu, but that showed that the graphics card was correctly recognised as ATI Rage Pro 128

Just in case, I checked the /System/Library/Extensions folder. There were no ATI Rage drivers there at all!

I hopped on over to OSX86 at Insanely Mac and read their forums, remembering my Hackintosh days of dragging drivers over and found that it was a trivial task.

Since I used Archive and Install so I had my whole Previous System folder available, I mosied on over to:

/Previous Systems/<somedate>/System/Library/Extensions

and grabbed all the ATIRage kexts bundles and plugins I could find.  I spotted the ATIcellerator, too so I brought that over to/System/Library/Extensions folder, also.

ATI Rage Pro 129 .kext files from Tiger.

I had to change the permissions of the files, delete the old extensions cache and reboot.

This needs to be done as root (using sudo) so be careful, a mistyped command will be executed without complaint by your computer, potentially hosing your entire system.

In terminal, type:

sudo -s

type your password at the prompt and you are now root. You can seriously shag your system up if you’re not careful. So be careful 🙂

chown -R root:wheel /System/Library/Extensions/ATIRage*.*
rm -rf /System/Library/Extensions.mkext

After the reboot I found that my system was much, and I mean that honestly, more responsive! The slow screen updates, windows resizes, dragging, Safari page scrolling, everything was much faster.

I imediately ran X Bench to see if the results reflected the performance differences I felt and here are the results:

 Leopard with generic v tiger driver

A convincing win for Leopard with the Tiger driver installed! It is a shame that OpenGL performance is not affected, however.

Just to remind us, let’s have a look at Leopard running with Tiger’s ATI driver versus Tiger itself.

Leopard with Tiger driver v Tiger itself

This is extremely interesting. It shows us surprisingly that far from having an overhead, Quartz graphics actually show a very slight increase in performance compared to Tiger (averaged over three runs)! Of course, X bench is fickle, so take this with a pinch of salt.

Unfortuantely, the OpenGL (spinning squares) test shows us that it not receiving any benefit from the new driver. That’s too bad.

Well, I can now reverse my original post with the following shout:
