  1. Firstly, yes, MacRumors did have this announcement first.

    Secondly, I have updated (smoothly) and I still don’t see any MobileMe service logos or anything, so I guess there might be one last update before the set release date…? I only mention this because it seemed to be widely reported this 10.5.4 update would activate the hidden code for MobileMe. Oh well.

  2. Any shutdown hangs like were reported with 10.5.3? I haven’t even installed 10.5.3 because of said hangs and because of Firefox incompatibilities. I guess I’ll wait a few days again and see what happens.

    MW: I’ll wait to see how “others” do with this update.

  3. Has anyone else had any issues with the EFI Firmware update 1.3??

    it was release on April 8th, and i’ve had issues with it (or System Updater) ever since. It constantly says that I need to install the update even though i’ve done so 3 times.

  4. Yay! Fixes Safari’s issue with loading some secure sites. I can finally access my bank’s site again. I was insistently blaming this on my bank for 2 weeks. ” width=”19″ height=”19″ alt=”grin” style=”border:0;” />

  5. God do Adobe charge crazy prices for CS 3. Over here in the UK we have to pay double what you folks in the US do. I say have to, instead of updating to the Master suite like I originally planned, I just got Illustrator and picked up the Apple equivalent when it comes to video production. Good times.

  6. “The Apple pie is always a trim size, just large enough to carry everything you need, but small enough to fit inside the tiniest of ovens. “

    Except when it’s a Leopard Pie. Then it’s so bloated and full of rotten leopard meat that it takes a whole year to bake a replacement pie.

  7. The “snappy” thing came from back when OS X 10.0 came out and was pretty slow and Apple released the update 10.1… It was a huge improvement in overall speed and it was often referred to as “snappy” Then whenever a new update came out like 10.1.1, 10.1.2 and so on it seemed some updates would be a step forward and some were a step backwards. It became commonplace to ask on forums if the newest update fixed any sluggish issues and if it made it “snappier”!

    So there you have it the history of “snappy” in reference to OS X!
