Operating Systems


Operating System Version Date Issue
Mac OS

10.7 (Lion)



















10.7, 10.6, 10.5

July 2011 Does not include Rosetta, Apple's compatibility environment for PowerPC applications. This is known to affect the following


  1. Oracle Calendar Client does not work. Workaround: Use the Oracle Calendar web interface with Safari at


  2. Microsoft Office 2008 (or older):
    • Cannot be reinstalled in Lion. Workaround: Purchase Office 2011, available from the Campus Computer Store.
    • Will not work if Lion is installed over top of and it is not fully updated. Workaround: Do updates to Office 2008 before installing Lion.
  3. Adobe CS4 (or older) does not run. Workaround: Purchase Adobe CS5, available from the Campus Computer Store.

  5. Adobe CS5 updates will not be reinstalled. Workaround: Do a full install of CS5 (will not work with upgrade version of CS5).

Entrust Certificates are not recognized in Safari. Users may therefore receive a warning when they try to access some services such as webmail, QShare, and Single Sign-On.  Workaround: Queen's uses Entrust, and users may safely trust the Certificate. See the Verify Certificate tutorial to learn how to accept the Certificate and bypass the warning.

Operating System Version Date Issue
Mac OS X 10.6 February 2012

New Trojan Effects Macintosh Users


There is a new variant of the Flashback trojan horse that infects Macs.

  • The malware first tries to install itself using one of two Java vulnerabilities. If either of these vulnerabilities are present the trojan will be successful and users will be infected without doing anything.
  • If Java is up-to-date then the trojan attempts to fool users by displaying a self-signed certificate, claiming to be issued by Apple. If the user clicks on Continue this will allows the trojan to install itself.

What this malware does

  • This malware patches web browsers and network applications essentially to search for user names and passwords. It looks for a number of websites such as Google, Yahoo!, CNN; bank websites; PayPal; and many others. Presumably, the people behind this malware are looking for both user names and passwords that they can immediately exploit – such as for a bank website – as well as others that may be reused on different sites. (Hint: don’t use the same password for all websites!)
  • One of the clues that a Mac is infected is that certain applications will crash. This is the case for web browsers, such as Safari, or other network programs, such as Skype. This is because the injected code interferes with the program making it unstable.
  • This malware also has an automatic update module that checks a number of websites for new versions.

How to Protect Yourself

  • Confirm all updates are done by going to the Apple menu and selecting Software Update. If you do not have all updates installed, there will be updates available.
  • If you see the self-signed certificate - DO NOT trust it. Cancel the process.
  • View the samples of self-signed certificates - both good and bad.
  • Install Symantec End Point (SEP) V11.0.7075 (or later) for Mac OS X. Download from
