I had a hardware failure (wi-fi/bluetooth module) that prevented the laptop from running. I spent a long time searching the log files for kernel panic info, and the web to figure out what was causing the issue. The Mac error message was useless. I could have really used this app since I was new to Mac's. I have it now though. Good job.

I, for one, would give the developer a break. He is offering a convenience in the form of instant access to information that can certainly be found on the internet without spending a dime, but not without spending valuable time and interrupting your work flow. Not to mention the fact that all those free internet tips are totally unavailable to you if the machine you're working on isn't working properly or won't boot normally. It goes without saying that, when you're out in the field, having essential information at your fingertips is crucial. Looks to me like this developer found a need and filled it. However, the app should definitely include many more shortcuts for the price.

As the local Macintosh “Go-To” guy, I often find I need to remember the many obscure startup keystrokes. This is even more critical when it is my own machine that is acting up and I cannot reach a browser with Google. iStartup fills those needs. It’s worth about $2 for the peace of mind, I would say. My only criticism is that the text is a little small — perhaps in version 1.0.1, the author could increase the font size a tad. Also, if the author increases the number of shortcuts (which I would look forward to), he or she might consider organizing them into functional groups (“at startup,” “troubleshooting,” “at shutdown”), as well.

When I don't have internet access and I don't recall any of these important commands I will use this. I like this app and find it useful even after owning a mac for 3 years and 3 different Macs. I highly recommend this. It does what it states and should get 5 stars for what it is. Its kinda like not having a back up you don't need it until your system crashes.
