First Impressions of OS X Lion

I Iz Upgrading Yor Makbuk

I upgraded my MacBook Air today to OS X Lion, and I thought I’d share my first impressions of Apple’s new operating system.

Download and Install

Lion is the first Mac OS to only be available as a download through the App Store, which is perfect for the MacBook Air.  The Air doesn’t have an on-board DVD drive — although you can use an external drive via USB connection — and with Apple pushing out a new model of the MacBook Air, you know they want everyone to go electronic copy only, no discs to ship or sell at the retail stores.

The download took about 20 minutes on my home network, and then the install process took another 30 minutes or so.  My immediate thought after the install started was, “Man, I probably should’ve done this on another computer first and not the work computer… oh well, too late now!”

Launch Pad

The first thing that shows up in the Dock after the install is the new Launch Pad feature.  It’s basically the iOS finder, where you can re-arrange your applications, group them, create new pages for the application lists, etc.  In other words, an entirely useless feature for the Mac.  I have the Dock already for my most-used apps; I have the Applications folder shortcut in the Dock for the less-common apps.  But, really, if you’re a power user on a Mac nowadays, you’re already using something like Spotlight, Quicksilver, or Alfred (my personal favorite).

Mission Control

Pretty much ruins my habits for using Expose and Spaces.  I had six Spaces pre-defined in Snow Leopard, with all of my common apps pinned to one of those Spaces (or all of them, in the case of iTunes).  After the upgrade to Lion, I had to reset my hot corners, and the Spaces become Desktops, but it’s an odd transition.  I wound up killing off all six Desktops for now, until I get the hang of Mission Control enough to start using multiple Desktops effectively.

Up/Down Scrolling

Which is natural to you?

This was the most jarring change for me.  Trackpad gestures reversed the movement of up versus down.  It’s like gravity has no meaning anymore!

Prior to Lion, when you used two fingers to gesture down on the trackpad (towards you, away from the keyboard), your app would scroll down.  In Lion, it’s the other way around — you gesture UP on the trackpad (away from you, towards the keyboard), and your app would then scroll down.

It seems completely unnatural to me, in spite of Apple calling that the “natural” scroll direction.  Luckily, you can disable that gesture and revert back to pre-Lion behavior.

I know that the “natural” direction is what’s used by iOS, and I’m completely fine with it on the iPhone and iPad, but it seems daunting to change that habit on the computer after years and years of mouse movements, scroll wheels and trackpad gestures.


iCal gets a HUGE facelift, looking just like the iPad version of iCal now.  It’s a huge step forward, and I found it very easy to use.  The quick create for events is going to take some time to get used to, but the couple of events I created today for work picked up my syntax perfectly.


Another daily use application that gets a major UI update.  I love that the 3-pane view is in the core product now.  Previously, I’d used a 3rd-party app to achieve that view, which of course would break on every OS update that touched Mail.  Conversations view is interesting, a little too much with the animation for my taste.  The new search functionality will be a HUGE benefit for me.  One thing to know when you’re first upgrading is that it takes a while to update your mail database, so carve out some time to let your Mac chug through the process before you need to immediately jump into your email.

Miscellaneous Stuff

  • Overall system performance seems a bit sluggish, especially when you’re switching apps.  I’ll have to see if eliminating multiple Desktops has an effect on that.
  • Full-screen mode is going to take a while to catch on, we’ll have to wait for all the 3rd-party apps to adopt it.  So far, the only apps that I use daily that have it are Mail, iCal and iTunes — none of which I’m ever able to stay in from a full-screen perspective.  I’m sure it’d be great for focusing on writing.  Maybe I’ll use Pages to write my next blog post, and go full-screen mode, just as an experiment.  Microsoft Word for Mac 2011 already has that feature, so no big whoop.
  • Time Machine… ugh… every time you do a major OS upgrade, it takes FOREVER to run a Time Machine backup.  30-something GBs were trying to back up over my home wifi today.  I had to cancel it for now since it was clobbering my network performance as well as the computer’s performance.  I’ll let it run overnight, and with the Ethernet USB adapter plugged in.


I use an external Western Digital hard drive to store my iTunes media and my iPhoto library, and it has to be connected anytime I want to A) use iTunes or iPhoto, and B) sync my iPhone or iPad.  Since the update to Lion, though, I’m finding that the external hard drive is unexpectedly being ejected.  I haven’t found any reports on the Internet about that being a problem with Lion yet, and I did a Disk Utility verify and repair, no problems found.  This could be a serious issue for me, I’ll have to keep an eye out for it.


  1. Hiya, Jason
    What kind of MBAir do you have? I’m concerned about what you term “sluggish” behavior generally, and specifically around task switching Me, I have a 13″ MBA with 4GB RAM, 250GB disk, and the 2.13GHz CPU.

    Out of curiosity, how much battery life did you get on a full charge, and has that changed with Lion?

    1. I have the 2010 model of the 11″ MBA, 4GB RAM, 1.6 GHz CPU.

      I’ll give you more of a progress report on the system behavior after spending a couple more days working normally with it. I suspect that the big two culprits yesterday were Time Machine and Spotlight indexing.

    2. Oh, and I haven’t really had a chance to see what the battery life changes are, since I’ve been plugged in the whole time since doing the upgrade. With Snow Leopard, I could get about 2.5-3 hours of use out of the battery on a full charge, assuming I wasn’t doing anything like iTunes or video.

    1. I did a bit more troubleshooting this morning, and I suspect that it was Spotlight trying to index the drive that was failing and causing the ejection. I disabled Spotlight indexing on that drive, and it’s been stable for 10 minutes now. That’s not saying much, but it’s better than what I was seeing before!

    1. I think I’ve isolated it down to my TV Shows directory from the iTunes library. There must be a file in there that’s corrupted, I’ll have to narrow it down further. I’d noticed a similar problem with Carbon Copy Cloner on the same volume several months ago, need to see if it’s the same file(s) that are affected. If so, those files will get deleted 🙂

  2. I would love to know whether you find that local Wi-Fi network performance/throughput is better in 10.7 than in 10.6.x:

    • around this time (whilst Time Machine properly handles the the post-upgrade mass of data)

    • in the future (after exceptional network and other activities have ceased).

    If I find relevant benchmarks, I’ll post to my microblog.

    Happy clobbering!

    1. Not that I’ve noticed, Graham. Didn’t have any benchmarks from before the upgrade, and I didn’t get around to doing an Apple TV home sharing experiment over the weekend. Other than Time Machine backups, that’s where most of my local Wi-Fi bandwidth goes to… the network at work is too unpredictable to get any real sense of throughput.

  3. I have a MacBook Pro, and i’m using an external NexStar drive (generic external drive). After doing Time Machine backups for several minutes it gets ejected unexpectedly too.
    Hope Apple fixes this soon!

    1. Ouch, Time Machine causing ejections is much worse IMHO than Spotlight.

      I’d suggest using Carbon Copy Cloner to try do a backup of the external drive, see if it winds up crapping out on a specific file or subdirectory.

  4. Similar problem with my Western Digital Element 2TB hard drives. The difference is that they don’t even show up in Finder, even though they are clearly recognized by Disk Utility. I’ve tried to run a scan and repair it, but it’s impossible to get any access to the files.

    That’s an unexpectedly major problem even for the first release of the new OS.

  5. I’m getting ejects as well on my 1TB WD as well. I got it hooked up to USB, I’ll try to use firewire instead.. OH WAIT!.. Apple removed the standard FW sockets in the iMac!..

    Anybody found a way to fix this?

  6. I’m having the same ejection problem on my WD 1TB Passport SE, I tried your advice, but it seems to keep ejecting…Especially now that I re-installed Front Row…
