Another of Lion's much-hyped features is Resume, the ability of the operating system and of individual apps to restore themselves to their last-opened state. Unlike Versions, support for Resume doesn't appear to require any effort on the part of developers.

When shutting down or logging out, the OS will now offer to reopen your windows when you next login - you can opt not to, but the option is enabled by default.

Individual apps will now do the same thing - if you quit Word or Preview with items open, all of those items will reopen the next time you launch the program. This is only optional to a degree - there's no way (as best as I can tell) to disable resume for an application for a single instance as you can do with the OS. Your options are limited to enabling/disabling Resume for the entire user account using the control found in the General control panel.

OS X stores information about application states in each user's profile, specifically in the now-hidden Library folder. Navigate there and open the Saved Application State folder, and you'll see folders for storing the states of every app you've opened on your Mac.

As with many of Lion's features, whether you like Resume will probably depend on how you work. In certain situations - crashes and restarts due to updates, for example - it's convenient to have all of your windows spring back open. Resuming individual apps was a bit more annoying - I actually like getting a clean slate when I reopen programs, so I found myself pressing command-W a bunch of times to close windows before I'd press command-Q to quit the program.

The main trouble for me is that all of your windows re-open whether you're just launching the program from the Dock or whether you're trying to open a specific file - I'd double click a Word file and get four different documents open at once instead of the one I actually wanted.

At best, Resume makes restarting your computer less troublesome than it once was. At its worst, it encourages and enables bad user behavior - the sort of people who will appreciate Resume the most are the same people who leave dozens of unused windows open in the background at all times, sucking up RAM and slowing down their computers. I can't tell people how to use their computers, but I can scold Apple for helping people use them poorly.

    I just installed Lion on a OCZ Vertex2 SSD and it still doesn't support TRIM. I guess support for this feature is limited to stock Apple SSDs only.

    Thanks for the reply. It is a shame that there still is no TRIM support.

    In the mean time I would recommend checking out a 3rd party program called TRIM Enabler:

    Though the program is designed for Snow Leopard it works for Lion, but they are making a new version for Lion.

    I love how these diehard Apple fans are trying to resolve their discomforting feelings of exorbitant expenditure to Apple by

    A: Unreasonably denigrating other competitive alternatives.
    B: Exaggerating the usefulness of certain proprietary tools.
    C: Empathizing with the company's goals/missions/values

    All to resolve the realization that they are paying more money than what they are getting, which is...

    A totally outdated OS made to look streamline
    A pretty cool looking computer that uses tunnel fans (which are extremely loud) and likes to overheat.
    I used Snow Leopard on my Mac Mini for about 2 months and hated it. I think people force themselves to like OSX just because their laptop looks cool.
    Horrible graphics speeds. Their BEST video card that you can fit into a their $4500 Mac Pro, is a ATI 6500 series, which is like a 100 dollar card, and offers pathetic performance for gaming--I had a 6950 2gb and that was barely enough. You can argue that Mac pro's should be used for graphics design and other things and not gaming. If that's the case I don't see why they don't put a FireGL or other designer cards in. In any case, who buys a $4500 computer that comes with a bullcrap video card? Some people are IDIOTS.

    Edit: A $170 dollar video card, 6870 1gb...Which is a complete piece of garbage card that is 30% slower than the 5970 1gb. Guess how much the upgrade is? $200.

    Macs don’t seem to be the right choice for you. That’s alright. Just don’t claim that everyone else has the same needs as you.

    The test with the SSD is intriguing but there's a possibility that the FileVault performance hit might be less in the case of a conventional hard disk.

    Reason: hard disks are slower than SSDs, so there would be more idle states in which the OS could be performing encryption/decryption tasks.

    Worth a spot-check.
  • EnerJi - Sunday, July 24, 2011 - link

    That's a great point. I'd also love to know if the performance impact decreases with an HDD.

    What annoys me is the fact that the recovery partition doesn't keep a copy of the Lion installer for instant re-installation - and with a bit of Apple magic even a copy that updates as the OS updates.

    A download each time is a possibly expensive prospect considering we all have data caps of some kind.

    It also turns a reinstall into a shockingly long 4 hour job which is a major pain.

    Small detail, but in the review you said you could only launch Launchpad by clicking the dock icon or using spotlight, but you can also set it as a hot corner. This is what I personally do... top left corner set for Launchpad and I can quickly get in and out of it to find my apps and utilities.

    I'm not suggesting it's quicker than using an apps stack on the dock... actually, its the exact same. But it definitely is faster than clicking the Launchpad dock icon or using spotlight to launch it.

    Does anyone know if Lion extended trim support to 3rd party SSD's, instead of only the ones apple provides ?
