Hey all, I have been looking into installing OS X onto an external USB HD that I have since I absolutely love OSX.

 

My computer is an Asus laptop, with 1.86 pentium m, 1gb ram, intel gfx/wireless, etc (915GM chipset iirc). The problem is that it is an SSE2 chip, and I have seen some people posting (not here, on other sites) that OSX without an SSE3 chip is dog-slow, and pointless to even use. I was wondering if this was indeed the case, or if SSE2 chips can handle it without too much of an issue.

 

Also, were I to try the 10.4.5 method that has popped up in the last day or two (basically a pre-patched DVD), is installing to a partition on an external drive doable, or does it have to be an internal drive.

 

Thanks in advance for any help!

I can only speak for myself, but SSE2 only is not at all slow. I can do anything I need to do, and even play World of Warcraft. It boots quicker than XP ever did, and I get a higher Xbench than many real macs (of course, not the new intel macs). I'm so happy with it that it's my only boot. So give it a try!

Yeah I'm using a 1.73 ghz P-M, works flawlessly. SSE3 doesn't really come into play unless if you run PPC only programs (right now MS Office is the only one for me).

 

It works fine as well on my system, though games are not as fast as with SSE3 (ie WoW is really faster on Windows in OpenGL than in OSX running SSE2, but still it's playable and impressive for SSE3 emulation).

 

In conclusion, as someone said, Universal Binaries are fine with SSE2 and games that don't use much the CPU like Doom 3 is damn fast even on SSE2 if you have a decent ATI.
