Mac OS X Lion Roundup: Recovery Partitions, TRIM Support, Core 2 Duo Minimum, Focus on Security

With the first developer preview of Mac OS X Lion having been out for over 24 hours now, some additional points of interest are surfacing from those who have had a chance to look through the build. Among the interesting observations:

- Apple has added support for a separate recovery partition, hiding away utilities needed for repair and troubleshooting right on the user's hard drive. The new system will allow users to boot to the recovery partition without the need for an operating system disc. The move, along with the shift to Mac App Store distribution for the developer preview, signal a reduced reliance on DVDs that may become important if other notebooks follow the MacBook Air's lead and see their internal optical drives removed entirely.


- As noted by MacGeneration [Google translation], Apple has added TRIM support in this initial developer build of Mac OS X Lion. TRIM support provides for optimization of solid-state drives by cleaning up unused blocks of data and preparing them for rewriting, preventing slowdowns that would otherwise occur over time as garbage data accumulates.

- Mac OS X Lion requires a minimum of an Intel Core 2 Duo, leaving out compatibility for Apple's earliest Intel-based machines offering Core Solo or Core Duo processors.

- CNET notes that Apple has apparently invited a number of security researchers to test out Mac OS X Lion, a move that seems to signal a more open relationship with those who are trying to find security vulnerabilities in Apple's software.

Seriously? People are whining that their now 5 year old computers won't be supported? :rolleyes: That's how technology progresses. 5 years encompasses a lot of technology.


I install windows 7 on my seven years PC and it screams! (Not just the noisy fan)

A new computer is also a significant investment for some, considering the continually sucky economic climate. Given that, I'd say you're a little too quick to dismiss people's concerns.

Core 2 Duo minimum?

Does that mean it will run crappy on a 2010 MBP or will it run smoothly?



2010? Really? That is really old! What possible reason would you have to still be using that? Didn't that come installed with Jaguar or was it Panther? Does it even run Leopard? I think it is time to upgrade that antique!

Well, there goes my still-perfectly-functional-and-used MacBook 2 GHz Core Duo. :(


Because when your neighbor installs Lion, his version will leap across to your house and kill your old MacBook?

Pretty pathetic that you would need an Intel Core 2 Duo or better to run it. This is Apple obviously wanting to sell more units. Shame. This is probably one of the contributing factors why my company is now phasing back to PC's.


Not sure if serious.

To be honest I don't think most companies adopt bleeding edge operating systems, and the ones that do won't be hanging on to core solo machines.

Nice to see Apple copying Windows' good ideas.

LOL for all the posts claiming that TRIM wasn't needed.

Not pathetic - smart. All Lion systems will be x64 systems. Developers won't have to worry about the tiny fraction of Intel Apples that are x86-only.

If you look my history of posting, you'll see that I've said

[LIST]
[*]Apple should have skipped Yonah (Core and Core Duo) and waited for Merom (Core 2) several months later. I said this before the first Yonah systems were released.
[*]I said that Apple should have dropped x86 in Apple OSX 10.6 - and made that release x64-only.
[/LIST]

32-bit is dead. Windows Server doesn't support 32-bit, and the next version of Windows client won't support 32-bit. Apple is doing everyone a favor by simplifying Lion.

In before people whining about how it won't run on their 8 year old Intel PowerBook and cursing Apple.

EDIT: in AFTER. Really?

I guess the next generation will be the one we were expecting as "the future of macbooks". :)
