Dunkelstern Posted July 22, 2010 Share Posted July 22, 2010 Just installed Snow Leopard 10.6.2 on my Acer Aspire 3620 (Leopard ran fine before but i need SL for newer Xcode). Specs: Intel Celeron M 1,5GHz (no SSE3) 2 GB of RAM (DDR2, slowest you can get) Intel 915 (GMA900 Graphics) To get the Graphics running i just copied over the AppleIntelIntegratedFramebuffer.kext from my Leopard install, left the rest where it was. Used Hazards ISO to install and selected the USBFix, some ATA fix, voodoo Battery, The PS2 Mouse/Keyboard Fix and VoodooPS2. I installed the 10.6.2 Legacy Kernel as that's the only one that doesn't crash the system. On Boot I experienced the dreaded blue screen and fixed with the paperclip method (Bridge Pin 6 and 12 in the external VGA Connector). Then i Mirrored the screens to have all things on the laptop panel. Now i got 2 remaining problems (ok, 3, sound doesn't work currently but thats no problem as i use a usb headset and that works): 1. On Startup the mds process is running amok, it eats the cpu. I thought perhaps disabling spotlight indexing will fix that but sadly it doesn't. If i kill the process multiple times eventually it stays dead so perhaps a script to kill it repeatedly would be a hacky workaround. But i think that is somehow related to: 2. All time displays (clock in menubar, number on the ical icon, system preferences for time/date, etc.) display negative numbers. Currently the clock displays "Fri -7:-31 AM" and the ical symbol displays "-49". How can this be fixed? I tried a multitude of AppleRTC.kexts (All the ones on the Hazard install disc) and google finds nothing related to that (someone in the forum had the same problem but no answers for that there, so i thought i post a new thread to make the problem more visible) Thanks.

crazyJAT Posted August 31, 2010 Share Posted August 31, 2010 I can confirm this also happens on a bunch of my systems. Asus P4B533-E with a Pentium 4 2.4 GHz Asus K8V-SE Deluxe with an AMD Athlon 64 2800+ Intel D865GLC with a Pentium 4 3.2 GHz Gigabyte GA-K8NF-9 with a AMD Athlon 64 3000+ - I have a modified dsdt.aml in /Extra with default patches and RTC, CMOS, HPET fixes all applied. - I am using the XNU modified SSE2/SSE3 10.4.0 kernel on a Vanilla Retail Snow Leopard 10.6.4. - The bootloader I used is Chameleon 2 RC4 along with a custom com.apple.Boot.plist and smbios.plist. - I have tried a nVidia 6200 LE, nVidia 8400 GS and an ATI Radeon x300 in the systems with no difference. /Extra/Extensions : ATY_Init.kext AppleACPIPS2Nub.kext ApplePS2Controller.kext Disabler.kext fakesmc.kext (2.5) OpenHaltRestart.kext PlatformUUID.kext SleepEnabler.kext I know these are older boards, but I am a bit of a hobbyist and I like the challenge of getting OS X to run on them. I recently received some older PCs from a local business looking to upgrade. Unfortunately, I do not have the tallent that a lot of you in the community have. I spend all of my day working as interface developer for a large game publisher. My knowledge of hardware development is very minimal. I am a quick learner, just have not had time, or found someone interested to teach me, to pick up the skills to know all of what I am doing. Anyone able to point me in the right direction? I hope that it will help expand the compatibility of Snow Leopard. Link to comment Share on other sites More sharing options...
crazyJAT Posted September 6, 2010 Share Posted September 6, 2010 This seems related directly to the CPU. If the CPU does not support SSE3, these problems occur. Does the XNU 10.4.0 kernel not support Athlon 64 and some Pentium 4 processors? Is the SSE3 emulation broken in Snow Leopard? Can no one help here?

crazyJAT Posted September 7, 2010 Share Posted September 7, 2010 I was able to confirm that all 4 systems that I have this problem with have CPUs that don't support SSE3. The boards support SSE3 CPUs, but I don't have any for them. So, I did a little research and found that the following kernels have the following outcome: The 10.0.0 test7 kernel from http://www.kexts.com/view/90-amd_kernel_snow_leopard..html - This kernel does not boot. The boot doesn't event get to Waiting for DSMOS... Stalls out after getting boot device. The 10.0.0 10a432 kernel from http://www.kexts.com/view/71-modbin_10a432_kernel.html - This kernel does not boot. The boot doesn't event get to Waiting for DSMOS... Stalls out after getting boot device. The 10.2.0 AnV kernel from http://www.kexts.com/view/190-anv_10.2.0_k..._amd-intel.html - This kernel will boot SSE2 CPUs, however it causes the pinkish background, messed up icons, negative time and date all screwy, as well as terrible stability. The 10.2.0 legacy kernel from http://www.kexts.com/view/157-10.6.2_kerne..._-pentium4.html - This kernel will boot SSE2 CPUs, however it causes the pinkish background, messed up icons, negative time and date all screwy, as well as terrible stability. The 10.3.0 legacy kernel from http://www.kexts.com/view/324-10.6.3_legac..._intel-amd.html - This kernel will boot SSE2 CPUs, however it causes the pinkish background, messed up icons, negative time and date all screwy, as well as terrible stability. The 10.4.0 legacy kernel from http://www.insanelymac.com/forum/index.php...p;#entry1492469 - This kernel will boot SSE2 CPUs, however it causes the pinkish background, messed up icons, negative time and date all screwy, as well as terrible stability. The 10.4.0 Qoopz AnV xnu kernel from http://www.kexts.com/view/475-qoopz_anv_xn...+dydld_fix.html - This kernel will boot SSE2 CPUs, however it causes the pinkish background, messed up icons, negative time and date all screwy, as well as terrible stability. Is SSE2 emulation going to be fixed for Snow Leopard? Link to comment Share on other sites More sharing options...
crazyJAT Posted September 8, 2010 Share Posted September 8, 2010 I'm guessing by the lack of any responses that SSE2 CPUs are just not compatible with Snow Leopard. This would include all Northwood Pentium 4 CPUs, most Pentium M CPUs, many Celeron CPUs, most Athlon 64 CPUs and many many others. That is just a damn shame.

Nicolai Bülow Posted July 21, 2011 Share Posted July 21, 2011 i have a Pentium 4 3.0 Ghz and it support SSE3 (it sayes) but i can't run snow leopard WTF'? i run iDeneb 1.4 (leo 10.5.6) with all working but i really want snow leo.... Link to comment Share on other sites More sharing options...
