Apple has historically used Samba, an open-source implementation of the SMB file sharing protocol, to share files with Windows machines. First included in OS X 10.2, Samba also enabled Macs to both join and host Windows-compatible directory servers, increasing the then-fledgling OS’s viability in a business setting. However, the Samba team recently began licensing the software under the GPL3 license, which prohibits its inclusion in retail products, and rather than lose these key interoperability features, Apple chose to develop its own in-house implementation for Lion. What does that mean for you, the user?

Well, for starters, Lion’s new SMB implementation is SMB 2.0 only - this is a Microsoft-developed improvement of the specification that was introduced in Windows Vista and continued in Windows 7. This has one major ramifications for Lion users, and I suspect it will only impact a fraction of a fraction of them: Lion computers can no longer be joined to NT Domain Controller directories. These directories are quite old at this point - their successor, Active Directory, came with Windows Server 2000 in 1999, and has become much more robust with each Windows Server release since - but if, for some reason, you or your business uses new or newish Macs on an ancient domain, Lion’s going to break things for you (Lion does, however, remain compatible with Active Directory).

You never want to see an OS lose features, but I can’t say I blame Apple much for making this call, and it’s not a secret that Apple has historically been much less interested in backward compatibility than Microsoft. For people who absolutely need for OS X to have this functionality, Samba is definitely still around, and I wouldn’t be surprised to see someone begin maintaining an OS X-friendly fork of the software. Just know Lion won’t do it out of the box anymore.

SMB’s main use in OS X is for file sharing with Windows users, though, and I can say that file sharing with users of both Windows XP and Windows 7 (and, by extension, Windows Vista, for what it’s worth) works just fine once you set it up in System Preferences. I was able to copy files to and from a basic share I made without issue.

Anecdotally, I can also say that connecting to and browsing through an SMB share with many files and folders feels faster than Snow Leopard does on the same system connected to the same share. In Snow Leopard, I’d often have to wait for folders with a lot of data in them to populate - in Lion, things are more or less instantaneous. SMB2 was optimized to improve speed over high-latency connections, and I’m sure that accounts for at least some of the increased snappiness.

    $29 is indeed a solid improvement. However, given the Mac Store now being out there, their desktop OS should follow the formula of their mobile OS: Free to upgrade. These features are nice but I can't help shake the feeling that these are Service Packs (because they are). And with their "app" store available on the OS and the means of most of their cash inflow, it makes more sense to make this a free upgrade for everyone instead of a $29 upgrade. Reply

    Service packs? Are you serious? Read up on the changes and try to come up with one service pack that changed as much.

    Some people…

    XP SP3 would be a good candidate, but yes, 10.7 is a bit beyond what one could reasonably call a Service Pack. Reply

    You're thinking of XP SP2, and if you have to go back 7 years to come up with a comparable "service pack", it's certainly fair to say OSX 10.7 is more than a service pack. Reply

    I fail to see how the age of the service pack matters. Xype asked for an example and qualified nothing. Reply

    Are we really going through the tired argument that every 10.x update to OS X is just a service pack and should be free? Then at what point should Apple try to recoup costs for OS development, because even if individual point updates are evolutionary, going from the original 10.0 to 10.7 has got to be a major change in anyones eyes. And the same questions could be raised about Windows NT 6.1 aka Windows 7 where the server version is bluntly labeled Windows 2008 R2 and Windows NT 6.0 aka Vista/2008 or Windows NT 5.1 aka XP and Windows NT 5.0 aka 2000.

    Besides, even if you discount the user facing changes, Lion has seem some major security infrastructure changes. Both the 32-bit and 64-bit kernel have been rewritten with full NX-bit and ALSR support as in place in Windows Vista/7 addressing the major security complaint Charlie Miller had with OS X. Application sandboxing frameworks are now available and soon to be mandatory for Lion apps in the Mac App Store which I believe is a security feature that even Windows isn't pushing yet. With the dropping of the Core Duo, the Lion has also be rewritten to make more use of SSSE3 instead of just SSE3 as pointed out by the Hackintosh community. Lion isn't just Snow Leopard with a few features added on top, but the entire OS has seem updates at a low level even if the user might not necessary see all the differences.

    And about the App Store being a major source of income for Apple, Apple has consistently said they aim to run their stores as a break even venture.

    I'm not clear if the iTunes Store in the graphic in the above link includes the App Store, but at the very least as an example of Apple's digital store, the revenue stream really hasn't increased in the last 2 years. Apple's sales growth is clearly from their hardware, iPhone, iPad, and even Mac.

    $1,634,000,000 in revenue from Other Music Related Products and Services (3)

    (3) Includes sales from the iTunes Store, App Store, and iBookstore in addition to sales of iPod services and Apple-branded and third-party iPod accessories

    I'd say their goal of a break even venture is not an accurate description of their stores. Hence the creation of the MAC Store. It sounds like a nice thought, but Apple is in business to make money and it seems their VERY good at it. Perhaps their projection analysis was a bit off.

    Hey, this is good news for the investors and I understand that they are a business. Lets not be too naive and just don't drink the cool-aid.

    Perhaps my finance terms are wrong, but I'd hope the Apps Store is taking in revenue. But if Apple should be offering some of their other products like OS X updates for free, shouldn't we be concerned with whether the App Store is making major profits, such that there is money to spare to pay for OS development?

    Revenue ≠ Profit

    They've paid billions to both developers, and music and video cotent owners. They've also spent money on the infrastructure to support their stores. I'm sure they're making a profit as all good for-profit companies should, but it's not the cash cow you've attempted to present here.
