Apple released the latest update to Mavericks OS X 10.9.2 yesterday. The update contains several application and security updates. Of major updates FaceTime has been updated with the the ability to make and receive FaceTime audio calls and several stability and compatibility issues with Mail have been fixed. On the security side a serious SSL vulnerability has been patched. Find more details about the OS X 10.9.2 update here.
Some MacBook Air computers sold between June 2012 through June 2013 have a defective solid state drive (SSD) that potentially could fail leading to a data lose. Only a minority of computers with 64GB and 120GB SSD drives are affected by this defective. Since the fall Apple has offered to replace all affected drives free of charge including MacBook Air owners with no AppleCare Protection Plan.
I have been running Mountain Lion on my mid 2012 MacBook Air and decided not to upgrade to Mavericks until I had time to do a fresh install rather than upgrading Mountain Loin. When a new OS X is released it’s normally a good time to clean up completely and start from scratch. Doing a manual backup, installing the new OS X, installing all applications again and then reload the manual backup is time consuming and normally takes out a full day. I got time during this month and it turned out my 120GB SSD was having this defective. Part of installing Mavericks is upgrading the firmware and this upgrade cannot be done on an affected SSD so no Mavericks this time… Instead this message popped up:
“MacBook Air Flash Storage Firmware Update could not update your drive. The firmware update tested your drive and confirmed it has an issue.”
A call to Apple confirmed that my Macbook Air needed a trip to the shop and my SSD has now been fixed. At first I was told that the SSD needed to be replaced but apparently they were able to fix the defective without replacing with a new SSD.
Apple has created a website for their MacBook Air Flash Storage Drive Replacement Program with specific details about how to find out if the SSD is defective and how to get it replaced or repaired.
From time to time the “Open With” option in OSX will get out of sync and begin showing duplicate icons or even start a different application than expected. Installing, removing or updating applications often causes this. On the Mac the associations between applications and file types are saved in a database called “Launch Services database”. Luckily it’s relative easy to fix this problem by rebuilding the database.
On most installations of OS X 10.5.x and later you can rebuild the database by running a few simple commands from “Terminal”. First open “Terminal” (If you don’t know how to open “Terminal” hold down “Command” and press “Space” once, type in “Terminal” in the text field that opens and chose the “Terminal” app). Copy the following code to the command line and hit enter.
.framework/Versions/A/Support/lsregister -kill -r -domain local -domain user; killall Finder;
The Mac will then rebuild the database and restart “Finder”. This can take anything from a few seconds to several minutes depending on your system. When completed the “Open With” option should be up to date. That’s it!
Several other websites recommend the OSX utilities Cocktail and OnyX if you fell uncomfortable working with the Terminal using raw commands. Besides fixing this problem they also provide several other options for adjusting and tuning your Mac.
