I cannot update anything with Software Update
Software Updates is not installing anything (Safari, iTunes).
It hangs for hours...
I tried downloading Safari 9.1.3 but after opening the installer after a few seconds it stops and says that the software was not installed.
I recently changed hard drive to an SSD, permissions have been repaired an infinite amount of times...
I have been able to install other software.
iMac, OS X Mavericks (10.9.5)
