Mountain Lion on AMD


Recommended Posts



I'm trying to install Mountain Lion on this machine:

AMD Sempron 145 2.8 GHz Single Core Processor


MSI 760GM-P23 (FX)

Sapphire AMD Radeon HD 6450 1 GB DDR3 PCI-E

450W PSU

250 GB HDD


*I know, it's amazing*



The progress:

Sound worked OOB (onchip)

Snow Leopard 10.6.3 running with legacy_kernel through ModCD




So the problems:

No QE/CI, rocking on 1024x768 through HDMI but I think this will get fixed when I get 10.8

No ethernet, which i think will come when I actually get 10.8 to work (Realtek RTL 8167)

When starting a sort of installed version of Mountain Lion it just restarts after the bootloader, probably cause of the kernel.





I'm open to try anything so give me suggestions.

By now, you must be aware that running Mac OS X requires special kernel, such as the legacy kernel you run (through ModCD installation) under Snow Leopard. No difference for Moutain Lion (or Lion) on that matter, if such a kernel exist for ML with support for single-core Sempron.


Sempron CPUs are really low-end so you'd better stick to SL in my opinion.


Since you're already on Insanelymac, do have a look at their wiki; it's well documented. You'll see that your Sapphire HD6450 is supported under SL and Lion and appears possibly supported under ML with patching.

There's a substantial thread at IM about AMD kernel for Mountain Lion. You can have a good look there. Remember that ML is normally 64bit kernel only, so if AMD kernels kept that line, your CPU needs to be 64bit capable.
