electrotech555 Posted September 21, 2011 Share Posted September 21, 2011 Hey fellow Hackintoshers! Last night I attempted to install Lion, and I had everything ready (Xmove, extra partition, and a usb rollback Kext just incase). So, I started up the installer after the 10.6.6 update I applied, and everything was going well until it told me to quit because I didn't have a C2D or higher processor. So, has anybody gotten around this? I understand compeletely why it wouldn't work, but if there is a hack of some sort, that would be cool. Specs: P4 2.8ghz (Overclocked 3ghz) Prescott 1GB DDR2 Intel X1300 Graphics MSI G31TM P21 Motherboard Thanks! BTW: I am currently working on a new Hackintosh so that I will have the Capability of running Lion. Another thing, Has anybody gotten the Gforce 450 card to work with the nvidia drivers? Not too sure about Lion compatibility because I don't have Lion at the moment installed on any of my PC's. Link to comment Share on other sites More sharing options...

So, do you think that I should get a developer preview version of lion? Link to comment Share on other sites More sharing options...
yhloh Posted September 22, 2011 Share Posted September 22, 2011 wait for legacy kernel, see if it support p4 cpu or just stay with 10.6.8. Link to comment Share on other sites More sharing options...
MTWomg Posted September 26, 2011 Share Posted September 26, 2011 Nothing to wait for. It will not work, ever. Finder.app is 64bit only with no 32 bit version. Even if you can boot the kernel, Finder (and many other apps) will never run. Link to comment Share on other sites More sharing options...
Raj_1990 Posted September 27, 2011 Share Posted September 27, 2011 if it says that ur system is not supported...jst replace the original OSInstall.mpkg with this one and it will work... OSInstall_Modified_.zip Link to comment Share on other sites More sharing options...
electrotech555 Posted September 27, 2011 Author Share Posted September 27, 2011 if it says that ur system is not supported...jst replace the original OSInstall.mpkg with this one and it will work... Thanks! I will try it in a little bit, and post what the outcome is. Link to comment Share on other sites More sharing options...
electrotech555 Posted September 28, 2011 Author Share Posted September 28, 2011 if it says that ur system is not supported...jst replace the original OSInstall.mpkg with this one and it will work... It still says "OS X Lion cannot be installed on this computer". It did fix the processor thing "Your need a C2d...... or above to install lion". Any suggestions?

Gringo Vermelho Posted September 28, 2011 Share Posted September 28, 2011 Late model P4 CPUs do have the EM64T instruction set though. I think the real problem is that the P4 is single core. The only Intel Mac with a single core CPU is the 2006 model Mac Mini which cannot run Lion because it uses a 32-bit Core Solo CPU. It can however run Lion if you upgrade its CPU to a Core 2 Duo. http://www.everymac.com/mac-answers/os-x-l...tible-macs.html We can do the same - "upgrade" the P4 CPU to a Core 2 Duo with... SMcputype 769 ...in smbios.plist...and it might just work. Not sure if this requires OS X to be willing to let Hyperthreading pass as two cores. Maybe the old P4-architecture based Pentium D models (with EM64T) can run Lion. Link to comment Share on other sites More sharing options...
electrotech555 Posted September 29, 2011 Author Share Posted September 29, 2011 Thanks so much! I edited an existing plist, and it worked. The only catch is that it recognizes it as a Core Solo. So, I am going to try a modded OSInstall.mpkg with Lion. Thanks for the help! Link to comment Share on other sites More sharing options...
a1ucard Posted October 3, 2011 Share Posted October 3, 2011 So, did u installed succesfully Lion on a P4? Did the apps (finder, etc) Work? How is the performance? Let me know, have a couple computers here that i would like to try on. Link to comment Share on other sites More sharing options...
electrotech555 Posted October 4, 2011 Author Share Posted October 4, 2011 Nope, not at all. I have an LGA 775 socket, so a C2D is just around the corner. I have 10.6.8, which does just about anything Lion can do minus a couple of new features. Snow Leopard Performance is ok, but my specs aren't great. I have a slow drive and 1gb ram, but it runs ok, and is useable. Overall, I couldn't get Lion to work. Something is up with the installer that checks to see what processor I have. The C2D fix didn't work because it recognized it as a Core Solo, which didn't help. I would say just stick with SL, it is your best bet. Link to comment Share on other sites More sharing options...
a1ucard Posted October 5, 2011 Share Posted October 5, 2011 How did u managed to update to 10.6.8!? im stuck at 10.6.6 with my p4 Kernel? Distro? Details plz Link to comment Share on other sites More sharing options...
tle88 Posted October 5, 2011 Share Posted October 5, 2011 > Maybe the old P4-architecture based Pentium D models (with EM64T) can run Lion. This happen, when someone patch kernel. Normal (="vanilla") mach_kernel need SSSE3 (read sharply: 3S) and older Pentium D have only SSE3 (=2S) multimedia functions. Different is quite little, but it is there. This is the reason, why we need rebuild "legacy_kernel" as need amd processors owners too. I buy new processor, second hand core2quad 9400, which have SSE4.1 functions, but I have 2 computer left which have older Pentium D945, and I really wait that someone have time to make "legacy" -version from xnu darwin mach 11 kernel.

LimaYock Posted February 16, 2012 Share Posted February 16, 2012 Nothing to wait for. It will not work, ever. Finder.app is 64bit only with no 32 bit version. Even if you can boot the kernel, Finder (and many other apps) will never run. There is a way of doing it. ALL system objects on lion have the chance of running on 32bit, so the CPU doesn't need to be 64bit to run the commands. The only problem is that you need to FOOL* the image to install, then remove the CPU restrictions on lion. Hope that helps. Link to comment Share on other sites More sharing options...
Gringo Vermelho Posted February 17, 2012 Share Posted February 17, 2012 With that out of the way, you'd still need a patched kernel. There is no patched kernel out for Lion yet, for the same reason it can not be installed on PCs with an AMD processor. Link to comment Share on other sites More sharing options...
