Why not? Time Machine only writes to the disk when if finds something
different. TM on a disk that is not changing won't fill anything up.
What you do NOT want to do is run Time Machine when there are really
humongous things that the OS thinks of as files. Say you have an
emulator such as Parallels or Fusion. To the Windoze side it is disk
C:, but to the Mac it is a FILE. Make a change of one byte in that
file and all 30GB or it, or whatever size it is, will be written to
the Time Machine volume.

Some programs -- notably Mail -- changed the format/layout/whatever of their directory (~/Library/Mail/) between 10.6 and 10.7.

You can still run Mail from both OS's, but you cannot *share* your home directory between them, you would need to have a home directory set up on each OS drive/partition/volume.

Just use the Snow Leopard partition for programs that require it. Use the Lion partition for the rest of your work. Don't try to save things between them.

Thanks for the responses, folks. I'm pretty sure dual O/S is something I want to do. I just have to figure out the best way to do it. I'd love some detailed advice. I've had a few different thoughts on how to do this, and am not sure which is the best way.

1. I do have my original Snow Leopard DVD, so I could do a fresh install on a different drive, then run the latest Snow Leopard Combo Updater and load my PPC programs one by one. That is probably the cleanest way, but it is a lot more work and I'd also have to redo a lot of settings, transfer some files, etc.

2. Or...I could use SuperDuper and make an exact clone of my current Mac HD Snow Leopard installation on the new drive. This would copy everything, and since everything is working fine, I guess that's an option. I have plenty of space on the destination drive, so that's not an issue. Of course, I'll be copying a lot of programs that I won't need on the Snow Leopard drive. I could then remove the programs I don't need on that drive.

I've not done this before, so please bear with me if I am asking silly questions...I just want to be certain so I don't do something dumb.

1. When I boot and run programs from my cloned drive, I assume NOTHING on my original Mac HD will be altered in any way. Is this correct? I want the two drives to remain totally isolated, as if they were separate computers. I may choose to write some data to a separate data HDD that both O/S's can access. But, I wouldn't run Photoshop from both boot drives, for example. I only intend to use the SL drive for my legacy programs.

2. Once I have my new SL drive running properly, would it be wise to install Lion now, or just wait for Mountain Lion and go straight from SL to ML? Is the upgrade seamless?

3. Should I remove all PPC programs from my Mac HD before installing Lion or Mountain Lion?

I will have multiple backups of my current Mac HD before embarking on this project.

Thanks again,

Lou

I run a triple OS on my iMac running Lion. I run Lion, Linux Mint and Win 7. Now that Linux has a good GRUB loader for OS X and an automatic install for OS X, it's pretty easy. This eliminates the need for rEFIt for a loader and is much cleaner and easy to remove. GRUB will sense all operating systems installed and give you the option of starting any of them. The installs were simple. The only need to use Disk Utility to partition was for the Win 7 partition.

Resizing partitions is pretty painless with Disk Utility. It does a non-destructive re-partitioning. I used this method rather than Bootcamp Assistant for Windows. You must still backup prior to the installs.

Yes.

I'm sure some people on this list are testing Mountain Lion, but obviously, it's not released yet, so you won't get much info about its behavior yet. It seems to me it's fine either way, and if you want Lion now, then install it. If you want to wait, then do that. I don't think there's any particular "wise" way to do it.

> 3. Should I remove all PPC programs from my Mac HD before installing Lion or Mountain Lion?

Once they are on your Snow Leopard drive, then there's no reason to have them on the other drive, so yes, uninstall them.

> I will have multiple backups of my current Mac HD before embarking on this project.

Good idea. I think this is all going to be a lot easier than you fear.

Thanks Daly.

I assume Lion can be installed directly over my current snow leopard installation without having to do a clean install. I have a TON of Apps on my computer, and the idea of reinstalling and reactivating them is not very appealing. Any liabilities to just upgrading my current SL install to Lion?

It probably will be a lot easier thank I am fearing--a test is always easy when you know the answers.

Thx,

Lou

Re: OSX Kext Issue

I'd be happy to suggest an alternate utility if you tell me what it
is you are hoping to accomplish with it. What is it that MacKeeper
offered to do for you that you are attracted to?

It's also important to know which version of the Mac OS you are
using. Lion has a special partition that you can boot into to do
repairs.

Has anyone else had a problem with the iTunes store in the past week? It won't let me buy anything, or download free items. I even bought an iTunes gift card for myself today, and they redeemed it, but I STILL can't purchase anything. Going nuts w/o my music.

5 Airpring & Safari Problem in iOS 5

Fri Jul 20, 2012 12:53 am (PDT) . Posted by:

"Harry Flaxman" hflaxman001

I have been having a problem using Airprint with Safari under iOS
5. Every other Airprint capable program on my iPod Touch work fine when
I use Airprint. Safari, however, will not recognize my printer and does
not see it as default when I try to print. I cannot see any pref
parameter that might be affecting it. It has, instead, a 'select
airprint printer' instead of automatically defaulting to my printer, as
the other apps do. When attempting to locate it, the app cannot find it.

I cannot locate the source of this, and nothing, short of reinstalling
iOS on the device, might even attempt to fix it. I do not want to go
through that procedure as it will probably be very time consuming with
no guarantee that it will work.

Can anyone assist here?

TIA

Harry

(regarding why I regarded myself as temporarily dissuaded from indulging my Retina-lust)

Your question made me look at the box my Seagate GoFlex Pro 7200 rpm 750 GB drive came in. The drive integrates the interface (I use FW800) into a proprietary connector to the plastic enclosure. I thought that's all I had, but looking into the box now I see there's a USB2 interface as well. I have no idea why, but another weird thing about this drive is that the USB interface also requires one of those "mini" USB to standard USB connectors such as one sees on mobile phones, cameras, and GPS handhelds.

I guess putting the interface into the connector allows them to minimize the size of the case.
