In April 2012, Apple started shipping a slight variant on the iPad 2 that remains for sale even as the third-generation iPad has become the mainstay of the line. This new version of the iPad 2 — labeled internally as “iPad 2,4” — uses a 32 nanometer version of Apple’s A5 chip that replaces the 45nm version in the previous iPad 2 model. The processing performance is the same, but AnandTech is reporting that the 32nm model has notably better battery life (and a lower manufacturing cost). Alas, there is no way to know if any given iPad 2 uses the new chip without running an app that reports on the internals. follow link
Fixing Save as Adobe PDF Crashes
There have been many reported instances of the "Save as Adobe PDF" workflow crashing regardless of application, but precious few workarounds or resolutions. In troubleshooting, I discovered that there were three instances of the "Save as Adobe PDF.action" in three different locations: /Library/Automator; ~/Library/Automator; and /System/Library/Automator. By eliminating all except the version in /System/Library/Automator, the workflow started behaving, and I was able to cut PDFs directly from the Print dialog.
