Lions, Tigers and Leopards, Oh My!

Our customers are adopting Lion (Mac OS X 10.7) at an incredible pace. A week hasn’t even passed and 50% of LicenseKeeper users have already adopted it as their primary OS. Knapsack users aren’t far behind with 30% having already made the move.

Because of this incredible adoption rate, I’ve decided to finally make the move to start dropping support for older OS X versions along with PowerPC (PPC) in our Mac apps with the next round of updates.


Mac OS X 10.4, Tiger, was released over six years ago on April 29, 2005.

Except for Bullfrog, almost no-one is still using Tiger on a regular basis. Because it’s free, Bullfrog won’t hold up this move.

LicenseKeeper: 0% of user base in last 60 days
Knapsack: Has never supported Tiger
Bullfrog: 15% of user base still using Tiger


Mac OS 10.5, Leopard, is now four years old and was released on October 26, 2007. More of our customers were already running Lion before it was even publicly released.

LicenseKeeper: 4% over the past 60 days
Knapsack: 2.5%
Bullfrog: 18%


Apple stopped supporting PowerPC Macs with the release of Snow Leopard in August of 2009 — three years ago.

LicenseKeeper: 1.9% PPC users over the past 60 days
Knapsack: 0.6% PPC
Bullfrog: 19% PPC


The next set of updates for each or our applications will require at least Snow Leopard (10.6+) to run.


I’m currently working on LicenseKeeper 1.8. I still have several open items to take care of which will then require a fair amount of testing. I’m hoping to have this update out in the next couple of weeks — sometime in August.


There is a lot planned for Knapsack over the course of this year. Knapsack 2.3 is scheduled to follow the LicenseKeeper update which will also require Snow Leopard (10.6+). Development on Knapsack 3 along with iPhone and iPad versions has already begun.


Because Bullfrog is free, it takes a low priority for us and tends to sit on the back burner. I don’t have any specific releases scheduled, but I will no longer be updating Bullfrog for Tiger and Leopard. Any updates that do make their way out will require at least Snow Leopard and possibly only Lion.

Questions & Concerns

If you have questions or concerns regarding these changes and plans, please let me know.

The current versions of our apps will continue to run on your existing configurations and you will not be forced to upgrade to the newest versions.


Happy Lion Release Day!

Today, Apple unleashed the latest version of their Mac operating system, OS X Lion via the Mac App Store.

We’re Lion Compatible

The latest versions of all of our Mac apps are Lion (Mac OS X 10.7) compatible and should run without issue.

Knapsack 2.2.2

LicenseKeeper 1.7.2

Bullfrog 1.2.3

If you do happen to find any problems with our apps and Lion, please let us know so that we can get a quick fix out.

Knapsack 2.2: Add Photos to your Itinerary

Knapsack 2.2 is now available on the Mac App Store and direct from our online store.

This new version gives you the option to add photographs and other images to activities in your itinerary. Photos are copied into your trip and displayed inline with the times, names, and descriptions of all the activities in the trip.

Printing trips has been improved to use a new cleaner layout that includes the new activity photos along with all location and trip photos.

Finally, with Knapsack 2.2, you no longer have to unschedule a trip to modify the number and order of days in your trip — even if the trip is sync’d with iCal.

You can read all about the details in the release notes.

Sneak Peek at Knapsack 2.2

We just submitted Knapsack 2.2 for review to the Mac App Store. Hopefully we won’t run into any snags and Knapsack will make it through quick and easy.

In the meantime, here’s a little peek at what’s coming in this update. Knapsack 2.2 adds support for Activity Photos. You can now add photos or other images to your trip activities along with locations and the trip summary.

Knapsack will copy the photo into your trip and will display it inline and include it when the trip is printed. Double-clicking on a photo will show you the full-sized image:

Look for the official release soon!

WWDC Itinerary

Apple recently announced dates for WWDC 2011 which sold out in about ten hours. With help from some friends I was able to procure tickets, a nearby affordable hotel, and free flights using miles.

I’m pretty excited about this year’s World Wide Developers Conference since I missed last year due to short notice and existing plans. With all of the new things coming in Mac OS X 10.7 (Lion), Apple is sure to provide tons of new information. I’m looking to be inspired as we plan for some new things coming from Outer Level.

As I was putting together my trip itinerary in Knapsack, I thought it would be fun to share it with any other developers also making the pilgrimage this year. Maybe it can save you some time when putting your plans together.

You can use File > Import Trips… to import the WWDC itinerary into Knapsack where you can customize the details for your own plans.

If you have any suggestions for activities or locations to included in the itinerary, I’d love to hear from you.

Outer Level Welcomes New Developer to the Team

As I mentioned in my 2010 End of Year post, it’s been a crazy year for Outer Level. Adding two new products (Knapsack and LicenseKeeper for iPhone) and jumping in to Apple’s new Mac App Store has kept me really busy. So busy that I’ve been struggling to get everything done that I need to.

I’d like to welcome Kirby Turner to the Outer Level team. Kirby will be helping out with new development on Knapsack, our travel app.

I met Kirby about a year ago when he first started joining us at the Boston CocoaHeads meetings and we got along right away. As I started considering the need for help, Kirby seemed like the perfect guy to help since he was always asking me about new Knapsack features and when the heck was I going to make an iPad version.

Kirby is an outdoorsman, long-time programmer, and even a budding author: “Learning iPad Programming, A Hands-On Guide to Building Apps for the iPad”

Knapsack 2.1.3

Knapsack 2.1.3 fixes several crashes and the validation errors many have been experiencing. This version also includes a bunch of underlying architectural changes that should improve overall performance and stability.

Read the full Release Notes for
more details.

Use “Check for Updates” under the main Knapsack menu or download it directly.

This update will be available to Mac App Store customers once it passes Apple’s review process.

UPDATE (Feb. 7, 2021): Knapsack 2.1.3 is now available in the Mac App Store.
