  • My poor MacPro 1,1 is still left out in the cold. Lion 4 life.
  • Security Updates for Snow Leopard & Lion Released... hit up Software Update. No specifics on what the update covers yet...
  • Seems great that they add support for microsoft 8, but the best part is the gift card change. Now we can scan our barcode and activate our gift cards.
  • This is awesome for someone like my wife who always seems to scratch the code on the back to damn hard.
  • It was really cool when I heard my Mac's fans run at full speed during the update.
  • You mean, the "roar"? :)
  • I wonder what will the next OS X be, they're running out of "big cats." Maybe they'll call the next OS X, "OS X Sea Lion." No one will notice....
  • It'll be grumpy cat ;). Or liger...
  • It would be a smooth transition to sea mammals!
  • Love my rMBP :)
  • I miss my Macbook Pro. :( One day, I shall obtain an iMac. :)
  • I just updated and everything seems to be fine.
  • The Safari update fixed the issue that MacBook Airs had with some sites showing random vertical lines in the pages. What a relief since I have been dealing with this issue since purchasing my 13" MacBook Air.
  • Typically, I have three go to websites for Apple information: Engadget, Gizmodo and iMore. But it was today that iMore showed me that Apple OS X Mountain lion had an update. Thanks guys, I would've been in the dark.
  • Uhh I can't wait to get my macbook! I just want it in my arms and ready!
  • hope it fixes the battery life issue on rmbp. it's not mentioned in the update fix list though :(
  • what apple should update is iWork. the version in store is still 09.
  • My four year old MacBook is struggling with Mountain Lion - I really wish I just left it running on Leopard.
  • The real question is how long will we get support on 10.8 to a .4? 10.9 is right around the corner and hopefully apple will continue to support 10.8 a little longer. seems like there OS lifespan has been going down.
  • A lot of this seems under the hood enhancements, so I haven't noticed anything major to play with. I'm interested in more showstopping features, hopefully we'll see something on the pipeline before the summer. 10.9? OS XI?
  • My wife's Mac book pro has had a battery problem. Hope this helps it out.
