asdesoso Posted May 27, 2017 Share Posted May 27, 2017 Good morning, I have a board (AsRock 775i945GZ) that max cpu support is pentium E5300 aka Wolfdale-3M in 45 nm process (with SSE4.1 disabled) , but Core 2 Duo E7XXX or E8XXX have SSE4.1 instruction set and are from the same family and stepping (R0). I putted an E7500 in this board but doesn´t seems to boot-up. I want to know if I can enable SSE4.1 on E5300 or if there is any emulator such as kernel to translate SSE4.1 request to SSSE3 or SSE3 to install and run Sierra correctly. Thanks for your attention. Have a nice day. Link to comment Share on other sites More sharing options...

Hi there, Generally macOS Sierra doesn't work on Core Duo or Core 2 Duo processors, but with clover's SMBIOS settings you can choose any number of SMBIOSes with Core i3 or i5 processors and then install macOS Sierra. I have macOS Sierra installed on GA-EP45-DS3R and an intel E8400 processor with iMac14,1 SMBIOS. you can also look here for more information. Cheers!

If I choose for example iMac 14.1 SMBIOS or other that have Core i3 or i5 without having SSE4.1 on my CPU I can install Sierra? Best regards.

Cyberdevs Posted May 27, 2017 Share Posted May 27, 2017 I see in your signature that you have El Capitan installed on your machine so I would say yes. You can at least try to boot into macOS Sierra installer. If you could successfully boot into macOS Sierra installer without any errors then you can move to second stage which is installing the macOS. I usually use a spare 32GB flash disk for installing new OSes and when I boot successfully into the new OS then I move to the next step. Link to comment Share on other sites More sharing options...

asdesoso Posted May 27, 2017 Author Share Posted May 27, 2017 Any time It doesn´t seems to boot up, it stucks at multiple ++++++++ signs after select HD to boot sierra installation. I putted a lot of SMBIOS (iMac 10.1-9.1-8.1-14.1-13.1) but with 10.1-9.1-8.1 SMBIOS I get a message in clover saying that this version of Mac OS X doesn´t support this platform at the top of screen. I tried with a separed HD to test. Thanks for your help. Best regards. Link to comment Share on other sites More sharing options...

Cyberdevs Posted May 27, 2017 Share Posted May 27, 2017 The whole folder minus apple folder would be better than just the config.plist Sent from my iPhone using Tapatalk 1 Link to comment Share on other sites More sharing options...

Cyberdevs Posted May 27, 2017 Share Posted May 27, 2017 Thanks for clearing that up Sent from my iPhone using Tapatalk Sierra will install and run perfectly on any Penryn C2D CPU or later, provided it has the SSE4 instructions set. Sierra vanilla kernel will not run on a CPU without SSE4. You cannot install and run vanilla Sierra on a non-SSE4 C2D even if you opt for the SMBIOS of a Mac normally fitted with a SSE4-capable CPU. That's just a fallacy. Unlike Wolfdate dual-core Pentium E5x00, Intel Wolfdale desktop C2D E8400 is SSE4 capable, hence the ability to run Sierra on that platform. Same goes for laptops which require Penryn C2D minimum, i.e. CPUs such as T9xxx, T8xxx or later. Does using the FakeCPUID help I wonder? 1 Link to comment Share on other sites More sharing options...
