Is there a more thorough guide for installing Lion on dell 1525


11 posts in this topic

Recommended Posts

Hello Gents, I've read all the posts here, but some of it's a little fuzzy to me, I'm not sure what exactly I need to competely upgrade from 10.6.8 on my Dell 1525 to 10.7.3.


Could someone point me to the steps that are explicit and detailed on how to upgrade? It's my only 'puter and I can't afford to be down and out without it.

What are you, 14 years old? I'll let you in on a little secret, that's not how you ask for help.


Nobody here can guess what you're having problems with, or where your level of understanding is at. "Explicit and detailed" means one thing to you and something entirely different to me. As long as I don't know what "explicit and detailed" means to you, then the best I can do is guess, but by then I start to feel like I should be getting paid. Can you understand where I'm coming from?


If you have trouble understanding a specific step from a guide, ask about it. "Some of it is a little fuzzy"....uh, okay, so what are you talking about?


Make it easy to help you. This is not a job, nobody here gets paid.


Additionally, you have to understand that running, maintaining and especially updating OS X on a PC always involves risks.

If you depend on your laptop like you say you should probably stick to Windows, or 10.6.8 if it's working well for you.


Or you could experiment with installing Lion on an external hard drive connected via USB.

Doesn't exactly help me to share your opinion on risks involving a procedure I'm clearly well versed in. I'm asking for your opinion on guides for a clean install of os x to upgrade me to 10.7.3, I realize I didn't share this but I have back up HDD that I can use to install lion onto, I'm looking for a complete guide. Not something that assumes I have already done a, b & c but doesn't share what A B & C exactly is.


I get your point, but please don't reply to a post without any actual helpful information regarding what I'm actually asking for. A more effective post would have been "There are always risks involved so be careful when installing a new os, but here's a few guides you might like to look at.."


Inform before you assume.

I'm sorry, but you've really got this whole asking for help thing upside down. "Inform before you assume" is your job. You're assuming people know what you need, but what I'm trying to tell you is that it's not really possible to tell how to help you with what little information you've provided.

You're the one who needs to "inform". I'm not the one who needs help here!


In a way you are only confirming what I said in my reply up there - your first post did not indicate to me at all that this is "a procedure you are well versed in".


I don't think the guide you are asking for exists and besides you continue to be incredibly vague - if you want help with something specific, then be specific when you ask questions. If you want to know about A, B and C, then just ask. You could, for example, post a link to the guide you're trying to follow and then refer to the specific part of the guide that you don't understand.


The basic procedure for creating a bootable Lion installer, which is widely documented all over the Internet, is this:


You're on 10.6.8, so go ahead and buy and download the Lion 10.7.3 installer from the Apple Store.

Use Disk Utility to partition and prepare your external hard drive, GUID, HFS+ Journaled. Make two partitions, a 5GB partition for the Lion installer and the rest for Lion itself. In fact, knock yourself out, make as many as you want.

Copy your existing Chameleon configuration (your /Extra folder) to the installer partition and then install Chameleon 2.1 to it.

Mount InstallESD.dmg and Basesystem.dmg from inside the Lion installer package. One of them is hidden (don't remember right now which one), enable view of hidden files to see it.

Use Disk Utility to "restore" Basesystem.dmg to the 5GB install partition.

Copy the folder named kernelcache from InstallESD.dmg to the Lion installer partition.

On the Lion installer partition, edit /Library/Preferences/SystemConfiguration/com.apple.Boot.plist and add the path to the kernelcache folder:

Kernel Cache


Delete the packages alias on the Lion installer partition and replace it with the folder /System/Installation/Packages from InstallESD.dmg.

Copy the hidden file mach_kernel from InstallESD.dmg to the root of your Lion installer partition.


Now try to boot from it. If your laptop does not support booting from USB, you can try booting it with your existing Chameleon configuration, the same one that you use to boot 10.6.8.


If you have any problems following these instructions, ask. But please be specific.

Nope, you're right, I'm cranky without coffee... I apologize.


Ok, so here' s my issues.. I'm using this guide as a reference - http://www.osx86.net/10-7-lion/14385-guide-dell-inspiron-1525-10-7-3-near-perfect.html

but I'm having some issues.. one I get a KP sometimes when I boot from the usb, even with -v -x, but when I do get to the lion install screen, my keyboard and mouse no longer function properly, I only have use of tab, enter, and the space bar. I was looking to see if there was a guide that included these details and whatever else I might be missing, just so I can do this only once and not have to go back a hundred times like every other time I've installed os x on a dell 1525.


Any thoughts?

For mouse and keyboard I think you need something like AppleACPIPS2Nub.kext and ApplePS2Controller.kext.


This guide looks good, well written:


Note that the guide requires an 8GB flash drive with the Lion installer on it:


...which, at a closer look, boils down to pretty much the same as I wrote above.

If you don't have any 8GB+ USB stick you can adapt the guide and create the installer on a hard drive partition instead.

Use the DSDT and Macbook4,1 smbios.plist from this post (register to download attachments):

Extensions go in /Extra/Extensions, the default location for DSDT.aml is /Extra. The same as always, same as on 10.6.8 that you're already running.


DSDT can't drive hardware. It can make hardware that already has driver support work better.

You'll need PS2 kernel extensions in order for PS2 input devices to work. You're most likely already using these very same kernel extensions on 10.6.8, otherwise you'd have no keyboard or trackpad.


I can't promise that any of this will work for you, all I can say is that it seems to work for others.

Well.you are not alone. A lot of people try to install mac osx on their computer just because they think they are doing something like advanced hacking( I dunno if that's why you are doing).Installing Mac OS X on a PC is damn easy when you know what are you doing and the reason for it.If you know the answers to 'why's then its simple.The core methodology is likewise regardless any hardware.If you get the idea how to make mac work on a pc you should be "enlightened".


You first have to understand the procedures and the reasons behind it.A 7 years old kid can easily read a thing but in order to understand you need to know it.learn about it.There is no guide that covers everything about hackintoshes.The main reasons for it because its not written by a writer.Its written by some geek sitting and experimenting in a dark room and if it did cover then it'd have been like a whole book.You need to learn about computers to understand the terminologies.


Well Now it depends how thorough you want to learn about it.Its a huge world and its sort of impossible to know about everything regarding to this world.Thus you need to be specific about your problems,You cant just say "it seems fuzzy."if something is fuzzy then ask other people or use GOOGLE!


Now should you come across a term that you dont know about then search it on the internet.


The ultimate things you'll need all the way are Time and patience.
