Mountain Lion on Mac Pro 3,1 ?

[kirkbross]

Apple's site says Mountain Lion supports early 2008 Mac Pros. I'm wondering if anyone has run into problems running Mountain Lion on a Mac Pro 3,1? (i.e. does it teeter on the edge of being unhappy).

I have been running since about a month after its release date with no major problem. The only thing you have to tweak iTunes settings a bit to make it look like the older iTunes, iTunes 11 is a big rewrite.

Plus IMHO when making new email accounts in 10.8 don;t use Mail to do it. Instead go through System Preferences->Mail, Contacts & Calendar's + button to add new email accounts.

I have several MP 3,1 machines running 10.8.3 very smooth here at work. I even have 10.8.3 running on my MP 1,1 with the Chameleon boot loader and it has been pretty stable and runs very well. You shouldn't have any issues on a 3,1.

Thank you all, kindly.

Any tricks for doing a clean install on a new drive or just download from App store, select new drive and install?

(I'm going to put 10.8 on a 256GB Samsung 840 Pro).

I usually like to download from App store, extract the InstallESD.dmg file from the download and restore to an 8GB flash drive. Then boot to the flash drive and install on the new drive.

This is exactly what I do for each install I do and to the OP, yes ML 10.8.3 works great on the Mac Pro 3,1. No modification required.

I usually make bootable flash drives when I do Windows installs, when I only have the (slow, tedious) DVD... but if it's a download to begin with, what's the benefit of this method?

I prefer this way so that it can be a clean fresh install and not installed from the original HDD.
