Q: I'm running Yosemite - OS X 10.10.4 - and Safari 8.07.  Ever since I installed Yosemite, nothing is working right on my late 2014 MacBook Pro retina.  Especially Safari.  It thinks my Gmail is malware, and I can't even update iMovie - preflight not signed

Hi - I'm running OS X 10.10.4 and Safari 8.07 on my late 2014 MacBook Pro retina. I can't get Safari to open my gmail because it thinks it's malware.  And it says the update for iMovie can't be installed because Apple didn't sign the "preflight" certificate"  - what on earth is going on?  I can't download YouTube properly either.


can anyone help???

MacBook Pro (Retina, 13-inch, Mid 2014), OS X Yosemite (10.10.4), Safari 8.07

    Hi,

    I have a similar problem. I'm running Safari on an iMac with 10.10.4. Whenever I launch Safari I get an error message that Safari cannot connect to Internet. The problem can be solved temporarily if I change the web proxies to "localhost" port 5016 but after having switched off my Mac and rebooted the proxies are back to port 80 and "localhost" is cancelled. As a matter of fact it's a bit nasty having to reset every day the preferencies. Does anybody know how to fix the problem?

    cheers

    I realize that it thinks it's malware - but why, and what can I do about it?  Thanks!

    Try a restart.

     

    Do a backup, using either Time Machine or a cloning program, to ensure files/data can be recovered. Two backups are better than one.

     

    Try setting up another admin user account to see if the same problem continues. If Back-to-My Mac is selected in System Preferences, the Guest account will not work. The intent is to see if it is specific to one account or a system wide problem. This account can be deleted later.

     

    Isolating an issue by using another user account

     

    If the problem is still there, try booting into the Safe Mode using your normal account.  Disconnect all peripherals except those needed for the test. Shut down the computer and then power it back up after waiting 10 seconds. Immediately after hearing the startup chime, hold down the shift key and continue to hold it until the gray Apple icon and a progress bar appear. The boot up is significantly slower than normal. This will reset some caches, forces a directory check, and disables all startup and login items, among other things. When you reboot normally, the initial reboot may be slower than normal. If the system operates normally, there may be 3rd party applications which are causing a problem. Try deleting/disabling the third party applications after a restart by using the application un-installer. For each disable/delete, you will need to restart if you don't do them all at once.
