In the comments to my near-desaster story of last week, several readers suggested I should have a look at a utility called AppleJack. In hindsight, I cannot tell whether AppleJack would have been able to fix the problems that caused my Mac to refuse me access to my main user account. I sure wish, though, that I had it installed so I could at least have given it a try.

In recent months, my MacBook has occasionally slowed down to a sleepy snail's crawl: applications would respond with a major lag, switching between applications would take a few seconds, and the time for launching another application -- including Activity Monitor for hunting down the culprit -- could be measured in minutes. I still have not found a general root cause for this behavior yet, but force-shutting down and rebooting would always get the machine back to its proper performance without any further problems. The last time I had to apply this remedy, though, I could no longer log into my main user account after the machine had rebooted. And this was just minutes after I had left Phil Schiller's keynote, looking at a full week of Macworld Expo '09 still ahead of me. Bad timing, really bad timing...

If you live a highly Internetworked life, there will likely be certain types of files that, after downloading them from the 'Net, you perform the same regular tasks on: say, archiving bank statements to a folder, printing electronic invoices, etc. You can highly automate processing such files by using Folder Actions attached to your downloads folder.

The recent huge Mac OS X 10.5.6 update happily, if somewhat slowly, updated my iMac. My MacBook, on the other hand, was another story...

In the comments to last week's post on the caveats of using invitations with iCal, a reader pointed out John Maisey's iCal Reply Checker. As it turns out, that little utility delivers a set of useful options that should have been built into iCal all along.

Making travel reservations online has come a long way, and some airlines now even include standard vCalendar files in their confirmation emails, so it takes just a few mouse clicks to add all flight-related information to your digital calendar. One such airlines is Lufthansa, who include vCalendar _invitations_. And that, I daresay, is a bad idea.

The free Griffin iTalkSync app makes the process of copying an iPhone (or 2nd generation iPod touch) iTalk audio recording simple and painless. I have lost yet another excuse for not having a regular podcast.

Indev Software's Mail Act-On extension for Apple Mail has been updated to version 2 last week. Among the new features are an improved user interface, support for undo, and applying rules to outgoing email messages.

Two weeks ago, I was still searching for the "perfect" Twitter client for the Macintosh. In the meantime, I've been testing yet another client called Syrinx, and I am so impressed with it that it is now the only remaining Twitter client on my Mac's hard drive.

Little more than four months ago I signed up for Twitter. While I am still not able to pinpoint exactly what it is that makes this webservice so appealing, I have since used it regularly to keep up-to-date with what some of my friends are up to, learn about 'net-related news that lies beyond my own radar, and find the odd gem of wisdom as inspiration. As much as I like Twitter per se, I am still a bit disappointed by the Twitter clients that are available for the Mac.

With a little help from their friends at SightSpeed, Dell have launched their own video chat service, aptly named: "Dell Video Chat." It's a nice touch that a Macintosh client for this service is available. But is there a compelling reason to use it?

Here's something I've missed since OS 9: a wee program that checks if your other programs are up to date. The App Update widget compares your programs against the listings at Apple, Version Tracker, and MacUpdate, and then offers download links to the programs that are outdated. It generated a few "false positives," but also reminded me of a...

Two weeks ago, I complained about something not being quite right with the way OmniFocus -- a task management application based on GTD -- handles repeating actions, which may cause most of a project's actions to be hidden from you. In the comments to that blog post, a reader suggested three possible workarounds. Here's how useful those workarounds turned out to be, plus an official view on the topic by the OmniFocus developers.

The bottom line I gave to my review of ScreenFlow, Vara Software's screencasting studio software, last month was that " ScreenFlow does deliver on the promise of providing a one-stop-shop tool for creating high-quality screencasts with excellent visual effects, and it does so in a polished, modern, and totally Mac-like user interface." Apparently, ScreenFlow also appealed to this year's Apple Design Awards jury.

When, three weeks ago, I blogged about Patrick Stein's "SmartSleep" preferences panel, which lets you configure a Mac laptop's sleep and hibernation (aka "Safe Sleep") settings, I explained that I wanted to use this software to switch off Safe Sleep altogether, because that feature had failed on my MacBook so many times that it was basically useless. I didn't expect SmartSleep to restore Safe Sleep's usefulness, but it did.

One of the fundamental concepts used in OmniFocus is that of "Next Action." Each project has a Next Action, and it is the very next task you have to get done in order to keep that project moving. Being able to focus on such Next Actions is tremendously helpful for managing a large number of projects without losing track of what literally needs to be done next. Due to a curious problem with the way OmniFocus determines what a project's Next Action should be, however, you may overlook some tasks without even noticing that they are being hidden from your view.

The Safe Sleep feature in more recent Apple laptops is a good idea in theory: every time the computer goes to sleep, the entire contents of its RAM are written to disk so that the machine's state can be quickly restored in case the computer runs out of juice while sleeping. No data loss, no waiting for the computer to reboot, and very handy for exchanging batteries without having to shut down the machine, too. In practice, though, this feature may not work quite as advertised, so you might just as well want to deactivate it, and you can.

Thanks to cross-platform GUI libraries, writing an application that can be deployed on more than just one computing platform is reasonably straight-forward. But there is more to making an application truly Mac-like than just compiling it for Mac OS X.

Psystar, the company that caused a bit of a stir recently by announcing a Mac-clone called "Open Computer" have now posted a video which, they claim, shows that machine in operation.

To find out a Mac's serial number, don't bother hunting for the tag on the machine's enclosure, as it's right there in the "About This Mac" dialog box. But what about looking up this information without being logged in?
