Over the last few weeks, many Mac users have discovered that attempting to launch some apps obtained from the Mac App Store fails, with the apps immediately crashing and thereby failing to open in Mac OS X. Typically you’ll see the app icon appear for a fraction of a second in the Dock, then disappear. For those who dig a bit deeper with Console and system logs, you’ll see a vague reference to error “service exited with abnormal code: 173”. It turns out the culprit behind the Mac App Store app crashing problem is a certificate issue caused by Apple (if that sounds like deja vu, it’s because a similar certificate problem occurred just a few months ago which also prevented app launching).

While this is undeniably annoying and surely should have been prevented by someone other than the end-user, the good news is this app crashing problem is easy to resolve, and you’ll be regaining use and access to your Mac App Store apps again in no time at all.

The Mac hosts file is a system level file located at /etc/hosts which maps IP addresses to host names for Mac OS X networking. Many users edit and modify the hosts file so that they can point a domain to a different IP address, whether for the purpose of local development, blocking sites, or simply to access alternate servers from various apps and system level functions. Most advanced users will edit the hosts file from the Mac OS X Terminal using nano or vim, but for those who prefer to stay within the Mac OS GUI, you can also modify the Mac’s hosts file through TextEdit, or even a third party app like BBEdit or TextWrangler. This offers a more user friendly option compared to going through the command line.

Many Mac users may like to adjust the font size of file names, folders, and other text found in the Finder of OS X. This is particularly helpful if you find the default text size of Finder fonts to be small and challenging to read when navigating in the Mac file system, where increasing the font size makes a notable difference in legibility, but it can also be used the other direction to decrease the text size of Finder items as well, thereby fitting more items on screen in list view. Whether you want to change the text to a larger size or smaller size is up to you.

Though just about everyone has our phones glued to us with a dedicated calendar app, for users who spend considerable time in the command line it can be more efficient to stay put rather than stray to another app or pick up a different device to flip around in the calendar and find a given date. With the help of a simple command line calendar utility, you can generate a calendar instantly, which is great for quick reference for dates and occasions. Going further, you can even generate a calendar for any date, in any year, and for any month, whether it’s the current year and month, last year, sometime in the Roman empire, or deep in the distant future of House Atreides.

That’s practically a regular occurrence on the web. Fortunately for Mac users, web life is a bit easier, because rather than opening those links into new windows or into the background, you have a third option: previewing a web page link using a little known multitouch tap trick built into Safari for OS X.

Live Photos are a great new feature for the iPhone camera, and while you can easily share them with other iPhone and iPad users or to a Mac, they come across as little movies unless the user has Live Photo compatible iPhone. Mysteriously missing is the ability to convert and save Live Photos as an animated gif directly from the iPhone Photos app, but with the help of a third party application, you can convert any Live Photo into an animated gif with minimal effort.

Many Apple device owners depend heavily on iCloud, iMessage, FaceTime, Apple ID, Siri, the App Stores, and the other myriad of Apple online services for their Mac, iPhone, iPad, iPod, and Apple TV to work as intended, whether it’s backing up to iCloud or sending messages to friends and families, using iTunes, or logging into the online stores, or authenticating an Apple ID. Thus, it’s not too surprising that potential downtime or issues with these Apple services can lead to user problems, with various error messages and failures to perform otherwise simple tasks. While sometimes issues with such services are user created, other times the problems are on Apple’s end, and so for troubleshooting purposes it can be very helpful to quickly find out if Apple services are online or if they down.
