It was less than 48 hours ago that I reported that Mac OS 10.5.7 was causing grief for some hackintosh owners who couldn’t wait to install Apple’s latest update on their netbooks.

What a difference two days makes.

MyDellMini Forums member “conq” has found a solution for installing 10.5.7 on the Del Mini 9:

  • Download the installer, don’t use Software Update.
  • Install 10.5.7, in my case i downloaded the Combo.
  • Let it reboot.
  • At the boot screen use the -x to enter Safe Mode.
  • After in Safe Mode run DellEFI.
  • Reinstall the Mini 9 Extensions and remove custom dsdt.aml file.
  • Reboot.
  • At the boot screen use the -x to enter Safe Mode.
  • After in Safe Mode run DellEFI.
  • Install custom dsdt.aml file.
  • Reboot.

But it gets better.

A thread in the MSI Wind Forums on 10.5.7 Battery Life claims that Mac OS X 10.5.7 can provide a significant boost to battery-life on hackintoshes. Poster “jackobus” claims that 10.5.7 boosted battery performance on an MSI Wind from 3.5 to 4.5 hours. Another poster “Dalton63841″ claims:

On 10.5.6 I was getting about 3 hr 45 min to a charge. With 10.5.7 I now get 5 hr 5 min

If accurate this amounts to increase of 33% with that machine’s a six-cell 4400 mAh battery — which is staggering.

So far, no battery love for the Dell Mini 9/Vostro A90 hackintoshers though. Several posters in the MDM 10.5.7 thread have commented that they have not noticed any improvement in battery life on that machine. Which is a bummer.

Biography

Jason D. O'Grady

Jason D. O'Grady developed an affinity for Apple computers after using the original Lisa, and this affinity turned into a bona-fide obsession when he got the original 128 KB Macintosh in 1984.

He started writing one of the first Web sites about Apple (O'Grady's PowerPage) in 1995 and is considered to be one of the fathers of blogging. He has been a frequent speaker at the Macworld Expo conference and a member of the conference faculty. He also co-founded the first dedicated PowerBook User Group (PPUG) in the United States.

After winning a major legal battle with Apple in 2006, he set the precedent that independent journalists are entitled to the same protections under the First Amendment as members of the mainstream media.

O'Grady is the author of The Nexus One Pocket Guide, The Droid Pocket Guide, The Google Phone Pocket Guide, and The Garmin nuvi Pocket Guide (Peachpit Press), the author of Corporations That Changed the World: Apple Inc. (Greenwood Press), and a contributor to The Mac Bible (Peachpit Press). In addition, he has contributed to numerous Mac publications over the years, including MacWEEK, Macworld, and MacPower (Japan).

When he's not writing about Apple for ZDNet at The Apple Core, he enjoys spending time with his family in New Jersey.

Given Hackintosh is, well, a hack to begin with - how can you trust it?

I'm tempted to start a thread stating the 10.5.7 update on my netbook has improved my sex life but instead I think I'll do more testing.
