Install Lion GM/RETAIL on a PC with only 1Gb of Ram

PippoX0 · July 15, 2011

HI,

This is a simple hack to install OSX Lion GM on older PC with only 1 Gb of RAM

Sustitute this patched OSinstall.mpkg on /System/Installation/Packages

on created Dmg for hackintosh

OSX Lion GM OSinstall.mpkg patched for only 1024 Mb RAM installation

OSInstall.mpkg.zip

Cheers

A better solution is to actually get 2GB of RAM. 1GB won't perform well.

Can you tell me how to patch this *2GB limit*?

thanks

Thank you very much.

This was very useful in getting lion installed onto a USB drive using a macmini which only had 1GB.

I could then move the drive over to a Hack-tosh.

Obviously, the person who said get 2GB of RAM didn't see all the value.

Thanks again.

thanks! I used this for a friend who wanted me to upgrade his computer but his imac only had 1 GB ram. I made him order a 6GB set from OWC but in the mean time I at least got his os installed, something he wouldn't be able to do by himself. he knows how to put ram in...

Can you tell me how to patch this *2GB limit*?

thanks

It looks like you just replace the file... if you are asking how it was done... he probably used a program like pacifist and extracted the distribution file and edited it so that it could accept a minimum of 1024mb ram: here is the file he edited:

Hey James I have an Asus Sabertooth X58 Mobo with 8gb G skill ripjaw ram and Lion will freezes up at the boot screen if I have more than 2gb installed. I am dual booting with Windows 7 and its a real pain to keep adding and removing ram on the fly. PLEASE HELP.

P.S- All of the ram showed up fine on SL 1.6.3 \ 1.6.7 \ 1.6.8

You mentioned something to another member about a patch but your response looked like Hieroglyphics to me do you know of any scripts that would fix this problem automatically or can you PLEASE PLEASE PLEASE explain to me how to edit that file step by step.

coelomate · December 12, 2011

Hello,

where is the file?

I'd like to use it to install lion

twilight.lee · November 14, 2012

It looks like you just replace the file... if you are asking how it was done... he probably used a program like pacifist and extracted the distribution file and edited it so that it could accept a minimum of 1024mb ram: here is the file he edited:
<?xml version="1.0" standalone="yes"?>
<installer-gui-script minSpecVersion="1">
 <options eraseOptionAvailable="true" hostArchitectures="i386" allow-external-scripts="yes"/>
 <title>MacOSX_Title</title>
 <license file="License.rtf"/>
 <conclusion file="Conclusion.rtfd"/>
 <script>
	 var minRam = 1024;
...................

Thanks for your idea. I got it.

Thanksgiving! Runs perfect on my Pentium D Hackintosh!

erk · October 2, 2015

Thanks for the patch. Someone gave me a late 2006 Macbook with 1GB in it, running Snow Leopard, but I wanted to install Viber which needs Lion, so I ordered some more RAM from Hong Kong off eBAy, but that will take weeks to get here, in the meantime the patch let me get on with the upgrade from Snow Leopard

Thanks again. :thumbsup_anim:

Panda Stirling · January 8, 2016

Thanks a lot

I just upgraded my Early 2006 iMac from Core Duo 2GHz to Core 2 Duo 2,16GHz, and i only have 1,5Gb of RAM, but with this, i could install Lion :lol:

Thanks again

EDIT: No D: It tell me "Mac OS X 10.7 can't be installed on this computer"

Even if i deleted all of the "PlatformSupport.plist" and "SupportedMachine.plist"

Install Lion GM/RETAIL on a PC with only 1Gb of Ram
