Installation

Installing Lion on the HP Probook 4x30s series laptops is actually pretty easy (compared toother hacks you may attempt). This is mostly thanks to the fact that the hardware is verygeneric and well supported by current versions of Mac OS and to all who have contributed tothe process including tonymac, MacMan, blueking, tegezee, Mieze, Zenith432, kozlek, bcc9,BigDonkey, philip_petev, Mac4Mat, RehabMan and others who spend many hours messingwith the technical details to make things run smoothly.

Here is what you will need:- A legal purchased "Install Mac OS X Lion.app" from the Mac App Store- philip_petev's HP ProBook Installer from here: http://www.tonymacx86.com/hp-probook...s-support.html- The latest Unibeast from here: http://www.tonymacx86.com/downloads.php?do=cat&id=3- Access to an OS X install, where the "Install Mac OS X Lion.app" is. Whether this is Lion orSnow Leopard, or Leopard, hackintosh or Mac, it doesn't matter.- A flash drive that can be formatted, anything 8 GB or bigger is fine.- For computers with high resolution displays (1600x900 or greater), a "mini SSDT" fromhere: https://github.com/RehabMan/HP-ProBo...T-DualLink.aml- For ProBook Installer v6.1.1: If you're starting with a version of Lion that is not the latest,gather the "combo" update from here: http://support.apple.com/kb/DL1582, and place it ona USB stick or other media.

1. Go to the Mac where "Install Mac OS X Lion.app" downloaded from the Mac App Store is.Your "Install Mac OS X Lion.app" must be present in the Applications folder before runningUnibeast (prior versions allowed you to mount InstallESD.dmg, but not the latest version).

Make sure you download the Unibeast intended for Lion.

2. Insert your flash drive, and open disk utility. Format it as Mac OS X Extended (Journaled)with a MBR partition map. Name it Installer. Note: If your flash drive is larger than 8GB,create a partition that is 8GB instead of the full size of the drive.

3. Exit Disk Utility, and run Unibeast, installing to that flash drive. When installing, be sure toselect "Laptop Support." Then select your flash drive to install it to. Let it finish to create yourUnibeast USB flash drive.

4. Copy the latest HP Probook Installer to the flash drive. You will need it later.

4a. If you have upgraded your screen from the standard 1366x768 screen in the 45x0s toeither 1920x1080 or to 1600x900, or you have a Probook 47x0s with a 1920x1080 or1600x900 screen, you must copy a "mini SSDT" to the Unibeast flash drive as/Extra/ssdt.aml. So, copy the Mini-SSDT-DualLink.aml from your Downloads to theclipboard, navigate to the Unibeast drive's /Extra folder, and paste it. Then rename it tossdt.aml. You may have to show hidden files or navigate to /Volumes/Installer/Extra directlyvia Finder's Go -> Go to Folder.. option. Having this /Extra/ssdt.aml on your Unibeast drivewill enable you to have a working screen during installation.

5. Now we are moving on to the laptop. If you have discrete graphics card (switchablegraphics) other than the Intel HD 3000, disable it in BIOS now. It currently does not work inOS X. If your laptop has an i5 or i7 processor, be sure to disable "Virtualization Technologyfor Directed I/O" in BIOS. If you can't boot for some reason, set all BIOS settings to default,and then try again, again making sure any other graphics cards are disabled, and"Virtualization Technology for Directed I/O" is disabled.

6. Insert the flash drive in one of the USB ports on the right (you want a USB2 port, notUSB3).

7. Upon boot-up, hit Esc, and F9. Then, select the USB hard drive. Select the Flash Drive,called Installer, and hit enter. Let it load.

8. Now you should be at the Installer screen. Hit continue to select your language.

9. Along the top, click Utilities. Then select Disk Utility.

10. Select your hard drive, and format it in however many partitions you want, with a GUID

partition map.

11. Hit Alt+Q to return to the installer after you have finished. Finish the install process likenormal, selecting the partition you just made.

12. After it restarts, you will need to once again hit Esc then F9. Then select the USB harddrive again. This time, select the partition you just installed Lion on, and hit enter. Make sureyou leave the flash drive plugged in.

12a. It will now say you need to use a keyboard. Plug it in on the other USB port on the right,and after the stupid prompt goes away, you can unplug it.

13. Finish the setup process like normal. After you get to the desktop, open the flash drive (it'scalled Installer in Finder) and copy the HP Probook installer to your desktop.

13b. For ProBook Installer v6.1.1 and greater: If you installed a version of Lion other than thelatest (eg. latest is 10.7.5, but you installed 10.7.3), you must update to the latest using the'combo update' downloaded from apple.com. This is because the ProBook Installer v6.1.1 onlysupports the latest of each major OS X release. Update using the combo update PKG and DONOT RESTART.

14. Run the installer, and select:

- From "OS X support kexts," select only the version that matches your laptop (4x30s) theversion of OS X you just installed.- From "DSDT generator/patcher" select your "ProBook model," a "Fan behavior" thatmatches your preferences, and your "Display type." If you have an Atheros 9285 WiFi miniPCIe card installed, choose the 9285 patch under "Optional patches." Note: you must selectone option from each of the first three groups to generate a patched DSDT. In addition, youmust have no DSDT present in /Extra/dsdt.aml at the time you run this option. If you wish toregenerate a DSDT later, you must remove /Extra/dsdt.aml, reboot, and then run theProBook Installer using your desired DSDT options.- Check the option for "SSDT" generator.- From "System definitions," select ONE system definition which matches closest your laptop.- Chameleon: This allows you to boot from your main HDD/SSD- From "Optional hardware-specific fixes,"- "AHCI 3rd party kext," You can apply this option later if it turns out your DVD drive is notrecognized by the system. It is not needed on every laptop.- "Graphic Glitch Fix," You probably won't need this, because you will have a custom patched

DSDT, but you can try without and see if you experience random blocks/lines on the display.This option can help sometimes.- "EDID generator" Recommended.- From "Misc OS X fixes"- "Color profiles," Recommended.- "Sleep fix," If you have SSD, "Sleep image fix" is recommended. This disables OS X versionof "hybrid sleep" where upon entering sleep, a "hibernation image" is written to the bootdrive. For SSD, you don't really want to write this file every time your laptop goes to sleep.- "blinkscreen" This option works around an issue where 1) all the screen brightness levels arenot available before the first display sleep, and 2) the screen brightness is not restored on afresh boot (still... currently only fixed if you're using the Chameleon boot loader). This optionwill very quickly "blink" the screen when you login, fixing the brightness issue.- "Screen brightness fix" Select an option here if you would like your screen brightnesschanged automatically each time the laptop starts.- "Extra tools" All optional. Select the ones you want.

15. Shutdown the computer, unplug the USB flash drive and attempt to boot from the harddrive. If it does not work (you don't see the Chimera boot loader), it is very likely you have a4k/AF (advanced format) HDD. If that is the case, see this link for more information (start atsolution 1 step 4, or solution 2 step 2): http://www.tonymacx86.com/25-boot0-e...ial-guide.html.

16. At this point everything should be working (WiFi, Audio, keyboard, trackpad, ethernet,etc.). Note for WiFi: You must have Atheros for it to work. If you don't you should considerreplacing the mini-PCI card that provides WiFi.

Other Updates

When new updates come out it is best to wait until someone here has analysed what is in theupdate and if any additional patches or rollbacks are required. And with all updates it is wiseto create a backup before performing the update, because you never know what is going tohappen.

If you want to understand more, get Pacifist so you can look inside PKG installers...

BIOS updates/hardware upgrades

If you ever make a hardware change or update the BIOS, you should re-patch your DSDT. Seethis thread: DSDT patch: HP ProBook 4x30s (4330, 4430, 4530, 4730) patches -- Updatedand this thread for a guide using MacIASL: Patching your DSDT ProBook 4x30s usingMaciASL

You can also re-patch your DSDT using the ProBook Installer. Follow these instructions

1. Remove /Extra/dsdt.aml. If you have a high-resolution screen, install Mini-SSDT-DualLink.aml to /Extra/ssdt-1.aml. Then reboot. After reboot, you are running without aDSDT (no audio, WiFi, battery, etc)2. Run ProBook Installer and select only the DSDT options you did before in step 14.3. Allow the ProBook Installer to create your DSDT, then reboot.

Optional Optimizations:

A number of the kexts that are in the installer are under active development. If you want, youcan update to these kexts as they are updated.
