    Safari problem on OSX Mavericks?
    I found several instances of this message in the syslog:

    "2014-07-01 19:19:06 +0100 Safari[281]: CGContextRestoreGState: invalid context 0x0. This is a serious error. This application, or a library it uses, is using an invalid context and is thereby contributing to an overall degradation of system stability and reliability. This notice is a courtesy: please fix this problem. It will become a fatal error in an upcoming update" Any ideas what it means and how to fix it?

    What makes you think the error is coming from Safari? What else is running? What Mac, what version of OSX and all the applications running? Any add-ons or extensions in Safari? What was (if you don't mind) the URL at which this error occurred?

    Never mind the first question, I see it now in the error message. Duh!

    I don't know whether the problem originates in Safari but the message seems to indicate that it does.

    I'm using OSX 10.9.3 on a Mac Mini and this occurs at start-up. The only application that is running at that point as far as I know is Trusteer Rapport. It is only recently that Rapport has started launching Safari to display a page saying that it has installed successfully every time I start up the computer. That was one of the reasons why I decided to have a look at the system log and found the error messages.

    I tried downloading and re-installing Rapport to see if the problem went away but the same errors are still in the log. This is a longer extract from the log this morning:

    My programming days are long behind me but I do know that a potential fatal error is not a good thing! Any help would be appreciated.

    I would say that Trusteer Rapport is your problem. Uninstall it, restart your Mac and I think you will be OK

    There is no need for any sort of AV on your Mac, and especially one that launches Safari for you, which to me, says its calling home, and thats not a good thing. Uninstall it (google to find how) or use the .dmg you installed it with, run it and should bring up the uninstaller and your problems should be gone.
    Dont forget to use the Reputation System if someone has helped you out !!!

    TM beat me to it. Get rid of Trusteer Rapport and see if the problem goes away.

    Sorry. I didn't look at the log closely enough before my second posting. Re-installing Rapport does seem to have worked. My guess is that it had failed to install a new version properly at shutdown a while ago and couldn't reconnect to the URL on start-up. It would have been helpful if the message had said exactly what is was that would fail at the next update. I didn't realise Rapport was a Microsoft product until now but that probably explains everything. My bank insists that I use it for on-line banking so I have to keep it installed.

    I just did a google search on 'Mac Mavericks Rapport problem' and got a huge list of hits and various problems.

    Why is it even installed??

    Bunch of the banks in the UK advise/want their customers to have it installed - don't know that it's required - or how the bank would be able to tell whether any particular computer has it installed or not.

    It's not really an anti-virus software - it's an anti-phishing software - suppose to keep folks from logging in to fake sites via phishing attempts.
    I cannot be held responsible for the things that come out of my mouth.
    In the Windows world, most everything folks don't understand is called a virus.

    It may be needed by some Windows users but from what I read about it Trusteer - Wikipedia, the free encyclopedia etc. the Mac OS X already includes such protection.

    Maybe the insisting bank people should get their brains up to date for their Mac OS X using clients if they are so insistent on having them have it installed!! Besides which, it seems the software doesn't even work properly and causes all kinds of problems - at least for Mac users.

    LOL, very true. Most banks around here can't even spell Mac OS X much less have any idea that it's way more secure than Windows.

    This is what happens when banks etc use ONLY Windows technicians. And as for insistence on Kaperskys AV!!!!!
    Hang on to those original install discs like grim death! Using OS X.7 or later make a bootable USB thumb drive before running Installer!
