How Loud Are Your Mac's Fans?

When they get hot, Macs turn on various internal fans to keep components cool. The noise can be annoying, but just how loud is it? If you have an iOS device with a built-in microphone, you can download one of many free sound meter apps (search on decibel in the App Store) and see if you're subjecting your ears to a truly unreasonable noise level.


PDFpen and PDFpenPro 5.4

Send Article to a Friend

Only a month after the last update, Smile has released new versions of PDFpen and PDFpenPro, their PDF manipulation software. Version 5.4 adds the capability to extract and edit files from PDF portfolios (collections of PDF files bundled together), fixes post-OCR selection in certain situations, and provides other minor fixes and changes. Also notable in PDFpenPro only is the significantly improved interface for creating tables of contents (what Acrobat calls bookmarks; the navigational aids that appear in Preview’s sidebar). New commands enable the creation of “child” and “aunt” entries, and keyboard shortcuts help users make entries much more quickly. ($59.95/$99.95 new, free update, 41.2 MB)

Check out the Take Control ebooks that expand on the topic in this article:
