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.

    I purchased a MacBook Pro when Leopard was due to come out. Apple mailed me a free upgrade DVD about a month after I purchased the MacBook. When Snow Leopard came out I purchased the upgrade DVD for something in the neighborhood of $30 if I remember correctly. I've done clean installations from all of the media and never run into an activation/registration problem.

    On the flip side, I paid $149 for Windows XP, another $149 for XP 64-bit (if only there had been driver support back in the day...), $199 for Vista and another $149 for 7. Granted these were over a slightly longer time period. Still, I can't help but think that some of the initial investment cost of the Mac has been offset by not having to spend significantly more on software upgrades to get the features or functionality that I enjoy having at my disposal.

    Factor in the inconvenience of having several iterations of Windows that were more or less junk, but still cost the same and it slides the scale further in favor of OS X in my experience. Now I can also get what is essentially a household upgrade in Lion for approximately $30 if I decide it is worthwhile.

    Don't take this as an attack on Microsoft and their Windows operating system, though. It is still an integral part of my computing experience every day and I really enjoy Windows 7 (in fact, it runs better on my MacBook than on most notebooks I've worked on). I just wish they would adopt a strategy that would make upgrading Windows more affordable for the do-it-yourself PC enthusiast.

    The amount of money Apple made on your purchase of their hardware more than covers the cost of the OS. Microsoft does not sell their own brand of computers. You can purchase a PC laptop for hundreds less than you can purhcase an Apple MAC.

    I love it how PC people have such a sweet feeling of entitlement.

    Have you ever had/bought/found a product that you were simply content with paying a premium for because it just worked well for you? Have you ever overtipped a waiter because the service was really good?

    You know, some people don’t have a problem rewarding either individuals or, yes, teh ebil corburayshns, for work/services well done.

    ??? "feeling of entitlement" ???

    Not sure what you mean, but I do work hard for my money and do have a choice of where I spend it and how much I'm willing to pay for a product or service. There is a HUGE difference between tipping a waiter for working hard to provide you the best experience, than a company who sells consumers the same technology I can get elsewhere for less and be just as satisfied with my purchase. I'm not a 'Scrooge', but I'm also not a fool. Meaning: A fool and his money are quickly parted.

    I build my own systems so I not just satisfied with what is put out by the large PC sellers either. Most readers here are not satisfied with being 'spoon fed' what we should be satisfied with.

    If you or anyone else wish to purchase apple products, your free to do so. Just don't expect me to give you a pat on the back for it.

    You seem to have missed the entire point that Microsoft OS upgrades are *hundreds of dollars* per copy and Mac OSX upgrades are $30 for multiple copies. Reply

    Umm, currently it is roughly 100$ for Home Premium (I paid 125 when I preordered Win7 Pro Upgrade edition), less at some retailers.

    Not to mention, you glossed over the fact that there does exist a "mac tax", which you would have paid on every mac you own, offsetting the total cost.

    Say I spend 2400 on 3 PCs (including OS) and you spend 3000 on 3 Macs. Performance is identical. It will cost me 300 to upgrade each one to Win7. It will cost you 30$ to upgrade all of your Macs. 2700 vs 3030, Interesting. I will have to go through another version of Win7 in order to catch up with you in cost. And I'm being generous with respect to the difference in price before upgrades.

    But, you know, you can install it on as many Macs as you'd like, so go nuts. Just don't pretend you're somehow spending less than those who buy Windows licenses.

    Sure, but let's compare apples to apples (pun intended). If Microsoft were to charge $150 for what little differences there are from 10.6 and 10.6 + hybrid iOS called 10.7 windows discs would never sell (who the hell buys MS discs retail that reads AT anyway?? Newegg has always sold oem discs MUCH cheaper-wait apple person NM). But to sit there and tell me that there isn't any major changes from XP to 7... that's just ridiculous. Reply

    I think you're the one who missed the point. Even with all these Win licenses, it'll still be cheaper than a Mac. Plus, you can get the Family pack, 3 licenses for $150... Reply

    I know this comment was a few days ago, but I had a laugh at your comment, so I just had to open my digital mouth and reply:

    "2400 for 3 PCS ($800 ea.) and $3000 for your [POS] Mac".

    If you paid $40,000 for three Chevy Malibus and I paid $80,000 for my one souped-up Corvette" I would have gotten RIPPED OFF! (No, actually I would have received A LOT OF TICKETS!!)

    A better comparison is

    $800 PC vs. $1400 iMac . Not 800 vs. 3000. * Incidentally, you can sell your used Mac for a lot more than the technically equiv. PC. I've used that to upgrade my Macs several times.

    * Think an $800 PC = Mac Pro? The Mac Pros have Xeon processors. You know better than I that Xeons are $400 or $500 each. The cheapest Mac Pro has *dual* E5620s @ 2.66. You can't build a octo-core Xeon machine for $800. And you've got to have a motherboard and a, what, case? Power supply? And a few other parts, right?

    So, you bought four copies of Windows for a single computer? You may be the only person to have done this... A more typical experience over that time period is: Windows XP "free" with new PC, and $100 to upgrade to Windows 7.

    With the amount of money you spent on OS licenses, you could have purchased both a Win XP computer (OS included) and a Windows 7 box (OS included) outright.
