Pentium G3258, ANY SUCCESS?

Recommended Posts

So I'm trying to get maverick running on this awesome CPU, I've had full success with Mountain Lion 10.8.5 but no go on Maverick.

 

Did allot of reading, tried a whole lot of stuff. XCMP Free Kernels, patched AppleACPIPlatform.kext  and  Apple Intel CPU PowerManagement Kext, etc etc etc...

 

Wondering if anyone has had any success with this CPU.

 

The rig is:

Pentium G3258

GA-z87mx-d3h

8GB  Kingston HyperX Genesis 1600Mhz Kit

OCZ Vertex 3 120GB

Sapphire HD 5770 Video card. 

 

Thanks!

After much reading and searching I have discovered that it is unfortunately unsupported by 10.9 (and later probably). Running Mavericks was more for kicks that anything else anyways.  I feel that Fundamentally OSX hasn't evolved much since Snow Leopard. The CPU runs super great on ML. (i'm using Niresh's 10.8.5 distro)
 
The system is used as a HTPC plus for Audio interfaces/DJ controllers to which all run better under ML anyways. 
 
The CPU is great, I'm running it at 4.4.Ghz (it could run it at at least 4.5 but the ventilation of the G4 case I used is not the best plus I had to stick to the stock cooler to make it all fit) I'll eventually replace it with a low Profile CPU cooler when I come across one I like at a reasonable price.
 
I do recommend a gigabyte z87 or z97 board. (I tried it on an H81 board and couldn't get past 4.2) I'm also a system builder and strongly recommend gigabyte both for quality and OSX compatibility.
 
One thing to be mentioned is I currently only have 3 P-States 8/32/44 not the end of the world.  I'm sure more would be possible through tweaking but I don't have the time for it right now. My Priority was to get it running as the old machine it has replaced was old and time to be retired.
 
Anyways Hope this is all helpful.
 
Regards,

P.S. Here are some pics of the final product.

I made it out of an old one.  

 

Got an old G4 from a client, Gutted, repainted, installed a mod kit for the mainboard, rewired the front panel, etc etc etc...

Mushin,
 
I was curious how you got Niresh 10.8.5 ML installed with your G3258?  I tried Niresh as well as vanilla installs with clover, and unibeast, all without success.  Were you able to pre load kexts or edit the plist file prior to install?  As a side note I did get Mavericks installed using clover, but its terribly glitchy.  I'm using a gigabyte Z97-HD3 motherboard, and the Haswell Pentium G3258.  Have tried UEFI, and bios.  You should make a guide!    :)

I didn't do anything special,

 

Just booted the Niresh 10.8.5 and installed without hardware kexts (Audio and network etc).  Then loaded my kexts via Multibeast (DSDT-Free option well).

 

Those z97 are being tricky.

 

I haven't had much luck with them,

 

I have a z97-ud5h here and can't get the dame thing to boot. it KPs all the time.  tried niresh, unibeast, etc... nothing...

    • Sierra installed without any issue, but cannot get GT620 to work. Installed Cuda and Webdriver and boots without issues, but home screen wallpaper disappears and screen becomes black. Is this card supported on Sierra?
    • I get this message no matter what I do, I've tried changing my SMBIOS to a newer model to no avail. Anyone no how to get the second install boot to work?
    • This is my first time doing Hackintosh. I've several other machines running Mac using UniBeast and Multi beast. I wanted to try Hackintosh Vanilla. So far, no luck. I followed the Guide and MacPwn Mojave Guide. 
    • Hello! I wanted to install MacOS High Sierra, but the SSD does not appear in Disk Manager. I have a Samsung Pro 840 250GB. Is there a Driver for Intel Gigabit 82579LM Network LAN for MacOS High Sierra?
    • This is my very first post and have looked around the forums to my question but I wasn't able to find the exact specifics that I need. This is my very first windows/mac dual boot project. I chose to attempt high sierra and I hope I am posting in the correct area. High Sierra seemed to be the newest that is possibly more stable than Mojave so I chose that. I'm reaching out to the more advanced builders and experienced people. I'm currently running Win 10 as of now and bought a separate SSD to install a macOS on. Before I invest time and energy into this. I'm wanting to get the best recommendations on what OS I should choose , if my hardware will be up for the task and my best plan of attack. I'll be honest I'm not ready to bang my head on the keyboard for hours. I've been there and done that.  My hardware was some of the best at its time in 2011 and I'm not 100% confident it will work with a more up to date macOS I'm also concerned about drivers for my GPU.  All input is welcomed   Here are my current specs:   CPU
          Intel Core i7 2600 @ 3.40GHz    28 °C
          Sandy Bridge 32nm Technology
      RAM
          8.00GB Dual-Channel DDR3 @ 668MHz (9-9-9-24)
