It forces the Mac to always try to boot into 64 bit mode (assuming the boot volume contains.

It’s unclear what happens if this is done on a machine that is not 64-bit capable, or if the method interacts with it (which overrides which?). This method sets the PRAM (parameter RAM) to tell the machine to boot 64-bi modet. I’m not a big fan of this method, because I’d rather edit a text file than mess with non-volatile machine settings in the computer itself. The PRAM method for always booting into 64-bit mode PERMALINK Insert arch=x86_64 into the Kernel Flags field. Library/Preferences/SystemConfiguration/ Use a plain-text editor, such as Text Wrangler. The change is shown in red below (“ arch=x86_64”). This is the method I use, because I can leave it set the way I want to having to hold down '6' and '4' keys at startup is absurd, it’s ridiculous that Apple did not provide a system preference panel for this. Sudo systemsetup -setkernelbootarchitecture x86_64

Update: Apple has added a command line setting for enabling the 64-bit kernel. With 32-bit firmware, you cannot boot into 64-bit kernel it’s not possible.Ĭhecking whether 64-bit kernel is in use The configuration file approach for always booting into 64-bit PERMALINK See this Apple tech note for which machines can boot the 64-bit kernel You Mac might be a few years old and have 32-bit EFI firmware (the code that runs to boot the Mac).

The reason not to boot into 64-bit mode is compatibility with software drivers of various kinds.

But they won’t see full performance that way. Your 64-bit programs (if any) will run fine on a 32-bit kernel, gaining the benefits of 64-bit-ness. Why not get a good chunk of that for about $25? Tests of photographic applications show that the gains of booting with the 64-bit kernel can be substantial, keeping in mind that a 30% gain via hardware often costs several thousand dollars more.

The former does not require an existing Mac/Hack, the latter does.ģ) Format spare MBR partition Mac OS X (Journaled) and install SL on it.Ĥ) Reboot on ModCD/ModUSB and select newly installed SL partition.ĥ) Complete initial installation settings to get to basic running SL system.Ħ) Install SL 10.6.8 Combo update but do not restartħ) Copy above model-specific /Extra folder to HDD rootĨ) Install and run EDP 1.9.2 (model-specific kexts + Chameleon + Hibernation fix, etc.Storage options for Mac Pro. Then a new main MBR partition was created on the recovered disk space and formatted NTFS.Ģ) Boot using either ModCD+SL 10.6.3 DVD or ModUSB/SL10.6.3 USB key. Existing single Win7 MBR partition was therefore reduced from within Windows to begin with. Here's my method with Nawcom's boot utility, SL 10.6.3 retail DVD and EDP 1.9.2.ĭ620 with C2D T7200 DDR2-667 RAM, 320GO SATA HDDġ) D620 being already configured with Win7, the target was a dual-boot laptop. Otherwise, it's impossible to install the OS on newly created & formatted Mac OS X partition as installer will want GUID partitioned disk only. When installing on HDD with existing Win/MBR partition (that you want to retain), do not copy "Extra" folder to USB key prior to installation, but directly to HDD right after installation. Now install and when it's done, update to 10.6.8 and run EDP 1.9.2 and make a build. Make sure the hard drive is formatted Mac OS Extended (Journaled) and GUID Partition Table. Now boot from your USB stick using "-v" or "-v -f -x" and then install OS X. If you have Dell Latitude D620 with Intel graphics, download and copy this Extra folder to your USB stick: Now download the latest certified Chameleon bootloader from here: Enter root password and let it copy away!

On Lion and Mountain Lion it does it by itself. If you are making it on Snow Leopard, be sure "Erase Destination" is selected. For destination, drag your formatted USB drive to the destination section. Go to the Restore tab, and for source, click "Image" and select your Snow Leopard DMG file or from the DVD menu if you have the DVD version. Go to disk utility and format a USB stick with Master Boot Record and Mac OS Extended (Journaled). Insert your Snow Leopard install DVD or if you have a DMG image that works too.
