It was less than 48 hours ago that I reported that Mac OS 10.5.

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

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.
