wai Posted February 9, 2013 Author Share Posted February 9, 2013 I also see there's a custom BIOS elsewhere on this site for the D820. I hesitate to try it though given the problems I'm having with what looks like it should be a plug and play install. Link to comment Share on other sites More sharing options...
Administrators Hervé Posted February 9, 2013 Administrators Share Posted February 9, 2013 Don't bother, it won't help you load the installer any better. If you can, try with a Lion version no higher than 10.7.3. Although EDP fixes it, 10.7.4 brought some ACPI issues. Maybe they're not bypassed by installer. I've never had any problem with my 10.7.2 version... Link to comment Share on other sites More sharing options...
wai Posted February 10, 2013 Author Share Posted February 10, 2013 Sigh. The legitimate (I paid for) copy I have is 10.7.4 Is there a boot argument that will wedge this? Link to comment Share on other sites More sharing options...
