Upgrading OSX from 10.5 to Mountain Lion?

thomthom

I should have done a 'clean instal', but I didn't know about inode's http://www.joabj.com/blog/?p=732

inodes? how do they affect a clean install?

So - are you recommending the intermediate upgrade? (And you got the intermediate upgrade fro free?)

how do they affect a clean install?

a clean instal zero's the inode record count, which does have a limited.
so all those trashed scripts, apps etc.. still take up inode counts and slow the machine down, the culture of auto updates of OS versions, means the counts being transferred to the next version.
One of my mac I secure deleated almost everything, folders files apps, I had plenty of memory and disc-space but it was slow as dishwater, I only had 5% left in my inode count... a full 'clean' instal revives the inode list, speed returns.

Yes and Yes, I didn't request it Apple just sent me an email asking if I wanted it. I think anyone on the dev list got the offer. I could post [as in snail mail] a copy to you, but I think you could grab it locally [for free]

I was thinking of completely formatting the hard drive. Would that work?

thomthom

Only thing is - I don't know how I can buy a license. Since I cannot use the app store if I want to wipe clean my existing HD and install ML directly. :s

use a Snow Leopard disc, just borrow one, there's no secret locks on mac software. the instal disc will wipe and reformat your hard drive if you choose that option.
instal all fonts and all languages. it's an oft made mistake to be selective, but some are actually shared if you write or debug complicated code...
set up your account, your user profile, your internet, icloud, apple ID, apple Developer registration.
Then buy Mountain Lion from the App Store
do an upgrade from here, not a clean install,
get Xcode, TextWrangler, Homebrew, and SketchUp when it's all working.

worry about others later

Why a clean wipe then an upgrade?

driven

if you do a wipe for both you'll need to re-setup all your network settings, login details, apple id's, etc...
and if you've only used it to go online to get the next you'll be carrying forward very little overhead,

I guess if you find it easy enough and save your settings off the computer a second 'wipe' install means a really clean system.

I just find it all takes time and I'm bored by the second instal, so take the quick option...

Since there isn't any locks on the discs as you say, can't I just install 10.8 and buy a license in the shop afterwards?

driven

There are no discs anymore... download only.
Although it's possible to make a full backup for emergencies, when I tried that with Leopard >> Lion it was a complete pain and waste of time, days wasted,

when I got the snow Leopard Disc it was probably 10hrs in total to go through it to Mountain Lion...

We have a 10.8 disc at the office...

did they make it or are apple finally appeasing all the IT guys worldwide.

If they have it try it, can always go the long root if it fails. It won't lock down your hardware, or anything silly like that,

have they also got a 'snow' disc just incase

Our IT guy burned the installer into a disc. I'll try it and see what happens.

How's the update going, it will be good when your 'up to speed'

thomthom

I've not had time to update yet. (Busy jolly times.) Going to talk to the guy that made that disc tomorrow. Hope to get this sorted soon.
(Though a part of me wonders if, as a developer, if it might be useful to have a copy of this old OS... dual boot?)

I've got that on my macBook Pro and when I completely dorked my iMac 48hrs ago, I wanted to use it to do a rescue but both partitions where to small...
I kicked myself because I haven't used the 'old' OS on it since I updated, just haven't found a reason to and had forgotten it was there, taking up space.

luckily, I was able to use unix in single user mode to rm the offending software and rescue my drive [no backups...]

word of warning LittleSnitch and CodeWeaver combined, can dork pThread's causing complete system lockdown.
