Q: Disk Utility not working at all

The problem began with my iMac (10.11.6) slowing down. I restarted, it worked fine for a while, then the problem returned. I tried three times to use the Disk Utility but the same thing happened every time: the start box would appear on-screen, I'd "tap" First Aid, then... nothing. Nothing at all. I tried then to Force Quit the Disk Utility, but for some reason the Force Quit option suddenly didn't work. All I had was the beach ball and the non-functioning D.U. box. So what's going on? Virus (I do have Trend Micro, but nothing's perfect)? Age?

    Uninstall the Trend Micro anti virus software. It's not necessary on a Mac and is probably the causing the issues you are describing with Disk Utility.

     

    Third party anti virus software is not necessary on a Mac and can only cause problems.

    Carolyn,

     

    Thanks. I thought of that -- and will almost certainly do so -- but a couple of things give me pause. First, I've had Trend Micro for more than 18 months and haven't had any problems. True, that doesn't mean a whole lot by itself, but still... Second, I'm concerned about the security issue reported in today's Wired board:

     

    <<Last week, RESEARCHERS DISCLOSED AN uncommon discovery: a zero-day iOS vulnerability that didn’t just work, but was actively being used by at least one government against a dissident. It turns out that mobile vulnerability works for Safari on Apple’s OS X as well, which is why you should go install the latest updates on your computer right now. (If you haven’t updated iOS on your iPhone or iPad yet—go do that first.)

    Apple released Safari 9.1.3 and the OS X security update yesterday, citing the work of Citizen Lab and Lookout, the two research teams that discovered the iOS exploit that Apple patched last week. The description of the vulnerability in the Safari update release notes says that “visiting a maliciously crafted website may lead to arbitrary code execution,” which sounds identical to last week’s iOS flaw.>>

    What do you think?
