Mac OS X Leopard 10.5 coming Friday, May 11, 2007?

Apple StoreWe don’t know the final release date of the final version of Mac OS X Tiger, but “the likelihood is quite high [that it was March 13, 2007] given Apple’s Mac OS X release history as charted here and no prior Mac OS X update has had a version number higher than 10.x.9. It’s easy to observe that the last update to a current Mac OS X version has been released prior to the release of a new version. Also [we] observe that the gap between the last revision of a current and new operating system has shrunk for the past three Mac OS X releases. If Leopard were to follow the same number of days between Panther and Tiger then Leopard would be released on March 27, 14 days after Tiger 10.4.9. I don’t have any confidence in such an early release date,” Switch To A Mac writes.

STAM analyzes much history and evidence and concludes the best guess release date for The OS That Will Replace Mac OS X Tiger as the World’s Most Advanced Operating System” will be on Friday, May 11, 2007.

Evidence, rationale and much more here.

  1. Sheer stupidity. The LAST day Apple would make announcement would be a Friday. Anyone in PR knows that Fridays are when news releases go to die – you post news on Fridays when you don’t want the world to notice.

    I predict that Apple will release 10.5 when it’s damn good and ready. I’d rather wait for it to be right that rushed like that abortion pushed out by another company I refuse to mention.

    You railbirds are like a bunch of kids crowded around the oven impatiently waiting for the cookies to finish baking. Yeah, I know. I can smell the cookies too. But as any good mom would tell you, be patient. Good things take time.

  2. Without checking the record … hasn’t Apple been prone to releasing new hardware (with current OS installed) just BEFORE a new OS launch? It would fit well with their pattern of getting early adopters to pay as often as possible.

    If so, I would expect new hardware first, and then Leopard after the dust settles.

  3. Oh, oh, my crystal ball tells me… $%*@ the crystal ball. I find all those divinations funny. People saying that according to the trend, mathematical equations etc. Leopard will be released on something, something. We don’t even have spring yet. Leopard will be released sometime between March 20 and June 21 and maybe later if something goes wrong.
    I know how anxious people you are, I am myself waiting for Leopard to switch but cool down.

  4. All this speculation reminds me of the Simpsons episode where there are all these mysterious ads for GABBO and homer is staring at GABBO IS COMING in the newspaper and holding at different angles to try and figure out what it is. Lisa comments that she doesn’t think he has enough to go on.
