Updating os x 10 4
Using the Chrome browser instead is reasonable for some users, but not a solution for others.A future bug fix update will likely address any underlying issues here, but who knows when it will arrive.A few variations of this trick was found on Apple discussion forums, and it involves using the command line to manually remove user cache directories from the /private/var/ — again, something we do not recommend, but some users on Apple forums have reported success with.Rebooting the Mac again as usual appears to resolve the issue for some, as reported on the Apple discussion boards.
A workaround if Safari is persistently problematic is to use Chrome browser, or Firefox browser.
Another less than fun situation with Safari in OS X 10.11.4 is an abnormally frequent beachballing, where web pages either don’t load at all or freeze up.
Eventually, this often crashes the web browser, or you have to manually intervene and use Activity Monitor to quit the errant Safari process in question.
While we strongly advocate deleting temporary /private/var/ folders the safe way with a reboot, which may resolve the issue alone, some users have reported that a reboot with impacted versions of OS X 10.11.4 does not adequately clear those cache folders and instead manually deleting some of the files can result in a functional OS X app launching process again.
We’re going to leave this process intentionally less verbose because we are unable to test it ourselves and can’t vouch for it’s effectiveness, therefore it should only be performed by technically advanced users who make a thorough backup of their Mac with Time Machine beforehand.
