Video Walkthrough of Mac OS X Lion Developer

[diamond.g]

Sandy Bridge is a very different chipset with changes in memory controllers and Thunderbolt (aka Intel's "LightPeak") requires necessary drivers. The new 2011 MacBook Pro's shipped with a specific 10.6.x disc/OS X with kext's necessary for these changes to operate. This is one extreme instance in which you cannot run an older version of OS X due to major hardware changes/introductions. So it's not about Leopard/Snow Leopard, it's about Snow Leopard that ships with the new MacBook Pro's being a version only available for use with these new systems.

AFAICT Sandy bridge memory controller is closer to Arrandales memory controller than Arrandale is to Core 2. So by that same token Leopard shouldn't run on a 2010 (Core i) MBP. Thunderbolt, (which afaict is not actually integrated into the chipset) shouldn't make a difference.

In order to utilize Thunderbolt you need the necessary kexts, etc. As point, nothing but the OS that shipped with the 2011 Thunderbolt MacBook Pro's will install. Sure, you could "hack" another OS X and install it, bypassing the issue, but you will have potential kernel panics and/or boot issues along with not being able to utilize new hardware.

Here is a comparison article with a chart, discussing differences between "Sandy Bridge", "Arrandale" and "Clarksfield" ("the body of last year's Arrandale and Clarksfield processors is called 'Calpella'."

Lion!

Won't run on my Intel Core Duo MacBook Pro.

So how come Leopard installs fine on a 2010 15" MBP. I guess that is the part I don't get. I know it should probably install fine on a 2010 13" since it is still Core 2. Wouldn't you run into the same issue with, say the 330M or SD card not being found?


I am interested in seeing more of Lion. I just was under the impression that when you purchased a new Mac you couldn't run the previous OS on it (which is opposite of how Windows typically works).

Again, it's hardware specific. Most Mac you can, re-read my posts, and do some googling, it's a lot of information. Unlike Windows BTO systems, Apple manages the software with the hardware so they do not have to code their OS to account for numerous hardware configurations unlike Windows, nor do you need to install third part drivers. Apple supplies all the kext's necessary to run the hardware (example you cannot install a PC based GPU in a Mac Pro as the firmware flashed isn't EFI/Mac compatible and the necessary kext's would be needed by Apple).

So again, it's system specific. Without splits hairs, it comes down to whether the newer hardware has significant changes that will impair the OS from running. Installs can be easily hacked, forcing an older OS on a Mac system, however you are playing with a system that may not work.

Any sign of the ability for TextEdit to save .txt with windows line endings? That omission has been annoying me for a good few years now.

AppleScript Editor can do it, ironically....

I have 10.7 installed on a MacBook AIR 11" & MacBook Pro 15" late 2008 and can confirm that I have had NO issues with any Graphic or Video Programs. PS,AE,AI. FCS C4D, and both of them only have 2Gb RAM!

That's great news to my uneducated ears

No issues with printer drivers?

You know, I think a lot of the new updates are things I'm not totally interested in. I'm not saying they are useless or that they are not of interest to a lot of people, but what I'm really interested is what is happening under the hood, and from a systems perspective. Like what's going on with

[*]Backwards compatibility of Apps, etc. (I think I heard Rosetta is going away, I'm sad to see that as I have quite a few PPC apps. Maybe Apple could open-source the Rosetta code so other companies could fill this gap)

Gone. No more PPC apps at all. Rosetta isn't even an option. I don't know if you could somehow install SL's Rosetta into Lion, but something tells me Apple made sure it will know and will block it just because.

[*]Resolution Independance

Not yet it appears.

[*]Terminal,

It has a fullscreen option.

[*]The Finder (Tabs like Total Finder, cut/paste, ftp support, an address bar that can be hidden for those that don't want it, etc.),

Nope. No tabs and no cut and paste, also there will never be an "address bar" in the Finder. Just use the OS X equivalent. The "Path bar".

[*]Quicktime Pro,

Still currently Quicktime X. It does have a few changes but nothing big that I saw yet.

[*]Will they allow different wallpapers on different spaces (like Hyperspaces)

Yes. You can. It's interesting though, you must drag the Preferences window from space to space with the desktop picture panel open and change it there. Each space can have whatever settings you want including different rotation times and locations of images.

[*]Will we see a multiple clipboard option (example: command+Shift+C) to allow more than one item on the clipboard at a time
No. Just use a third-party app. I use an old PTH Pasteboard.
[*]The Mail App, iCal

Both have Fullscreen options and completely revamped (More like iOS) UI's.

[*]How about that old feature where you could store a mobile home folder on an external drive or iPod to take with you

No, sadly. I think it's all about the cloud now. Just sync whatever files you use everywhere to the cloud (Be it DropBox or MobileMe) and access it from whatever device you want like iPhones, iPads and MacBook's.

[*]Frontrow

Gone! Finally! There are much better options, and the AppleTV pretty much sealed its death. I personally use Plex/Nine because Boxee and XBMC suck balls.

P.S. on "FUll screen apps" do they still use the main bar at the top of the screen? if not, is there a way to force it to always be visible? I would like that to always be consistant.

I dunno. But I do wish you could have it show in all apps.

Make sure you watch my second video. I cover a few of your questions in it.

Aww, I liked using it to watch Apple's HD trailers fullscreen. What are my alternatives?
