Today I decided to update to OSX Yosemite. How much time would it take? 1 hour, 2hours? It appeared to get stuck to “one minute to finish” the installation for quite some time. During the upgrade process if you move the cursor to the top of the screen a menu will appear. One of the options is: “Show Log”. This option pops up a window that shows detailed information about the process.

In my case for around half an hour it was logging events like this:

 Nov 16 12:54:13 MacBook-Pro.lan OSInstaller[411]: (NodeOp) Move "/Volumes/Macintosh HD/Recovered Items/usr/local/texlive/2012/texmf-dist/source/latex/koma-script/doc/english/common-1.tex" -> "/Volumes/Macintosh HD/usr/local/texlive/2012/texmf-dist/source/latex/koma-script/doc/english" Final name: "common-1.tex" (Flags used: kFSFileOperationDefaultOptions,kFSFileOperationSkipSourcePermissionErrors,kFSFileOperationCopyExactPermissions,kFSFileOperationSkipPreflight,k_FSFileOperationSuppressConversionCopy)

It appears it was taking a lot of time processing the texlive files. I had installed texlive in the past, but i haven’t used it at least in a year. So, before upgrading to Yosemite make sure to delete any unwanted applications for a faster upgrade!
