On Friday Apple unleashed Mac OS X Leopard on the awaiting public and the masses rushed to Apple Stores, mail boxes and "download sites" to get first looks at the furry big cat.
Unfortunately first time adopters of software are bound to be stung by bugs that failed to have been squashed during testing. In fact it appears that moving to any first release of Mac OS X is a risky business, almost all versions have been fraught with issues.
Leopard appears to be no stranger to these issues, bring on the blue screen of death. Well, maybe not that drastic but it certainly caused a stir over the weekend.
To recap for those who have been sleeping for the last three days, multiple users have suffered from a “blue screen” after upgrading to Leopard: they upgrade, reboot, and get stuck at a blank blue screen.
As of writing this it appears the issue is no longer a mystery and the cause has been found, third-party application by Unsanity called Application Enhancer. In particular older versions of APE, it seems anything preceding 2.0.2 can cause the blue screen issue.
Unsanity clocked onto the issue and tried to help out but was keen to respond to those judging them by stating that users should upgrade old software before moving to a brand new operating system. But what if you didn't even know you were running APE?
It seems that during the installation of the Logitech Control Centre (which comes bundled with their mice) it kindly installs APE. Currently the Logitech Control Centre installs version 2.0.3 of APE but has, in the past installed older versions, causing many users to be blind to said applications existence and thus causing "widespread" issues with Leopard installs.
Apple has kindly stepped up to the plate and released a Knowledge Base article, which is essence states that users should Archive and Install as opposed to upgrading and update third-party "enhancement" software.
