Jason Hook's shiny new blog...... :: 7 Hours to upgrade to Snow Leopard

Tags: Mac

A quick note for those planning to upgrade to Snow Leopard: check the kind of partition you intend to install Snow Leopard on.

Somehow I managed to have an Apple Partition Map (APM) rather than the GUID style needed. The fix was simple but a little time consuming. If you know a better solution than this, please do tell..

Installed the brilliant "Super Duper"
Connected a GUID formatted external drive
Used Super Duper to make a botable copy of my internal drive [3 hours]
Once complete rebooted and booted from the external drive by holding down the option key as the computer booted and chose the external volume
Used the OSX disk utility to repartition and format the internal drive ensuring that you I chose the GUID partition type, I formatted with the extended journaled fomat case insensitive [I was erasing all the data on my internal drive at this point so I checked the copy I booted to make sure all of data was there and that I repartitioned the right drive]
Used Super Duper to backup [restore] the external drive to the internal drive [3 Hours]
Rebooted with the USB drive disconnected

Snow Leopard would now install. Installation seemed to take about an hour. The result's aren't spectacular but this Macbook seems faster and I haven't found any appplications that won't work yet. Not sure how I ended up with the APM but I suspect it's a default option.

All in all the upgrade took 7 or so hours, Is it worth the effort? The jury is still out but things in general feel a little faster which is good.

50 - Sometimes people are layered like that. There's something totally different underneath than what's on the surface. But sometimes, there's a third, even deeper level, and that one is the same as the top surface one. Like with pie.

53 - The Internet is like alcohol in some sense. It accentuates what you would do anyway. If you want to be a loner, you can be more alone. If you want to connect, it makes it easier to connect.

54 - Your first appearance, he said to me, is the gauge by which you will be measured; try to manage that you may go beyond yourself in after times, but beware of ever doing less.
