Depending on how you run/install SmartGit, on upgrade you may run into read-only file system problems which are caused by App Translocation. This happens:

  1. if started directly from the DMG file by double-clicking the SmartGit.app; or
  2. if copied from the DMG file to a different location (like Applications) without using Finder, e.g. from terminal by cp -R /Volumes/SmartGit\ 20.1.2/SmartGit.app /Applications

In both cases, in SmartGit’s About dialog, page Information, we can see for Java Version a translocated path containing AppTranslocation.

To resolve case (1), we can simply copy SmartGit.app from the DMG file to the preferred location (e.g. “Applications”) using Finder.

In case of (2), from terminal, we can see that the extended attribute “com.apple.quarantine” is set:

$ xattr -l SmartGit.app com.apple.quarantine: ...;...;Safari;...

We can get rid of this attribute using:

$ xattr -d com.apple.quarantine SmartGit.app

Now, when restarting SmartGit, the About dialog will show the actual installation path.
