I installed Android Studio via homebrew “brew cask install android-studio” as a part of my automated Mac OS setup. Recently, Android Studio prompted me that an update is available. When I accepted to update, it failed with an error “Studio does not have write access to /private/var/folders/wt/rjv6_wcn4f97_2nth7fqftqh0000gn/T/AppTranslocation/19A80F28-865B-41FC-AA87-B8E43C826FCB/d/Android Studio.app/Contents.

This blog post contains a collection of small tips for engineers migrating from GNU/Linux to Mac OS X for software development. Note: In another post, I wrote about why there is a dearth of a good GNU/Linux laptop.
