When we wrote about the Google-data backup application CloudPull 2.0, the most obvious problem was its performance when bringing in large quantities of email from Gmail (see “Back Up Your Google Data with CloudPull,” 6 March 2012). John Brayton of Golden Hill Software took note of this, and improved the performance significantly in CloudPull 2.0.2 by addressing inefficiencies in how CloudPull interacted with Gmail via IMAP. But that has remained his focus for the just-released CloudPull 2.1, where he has enabled CloudPull to use four simultaneous connections for far faster performance yet. That in turn tends to set off Gmail’s throttling for clients that use excessive bandwidth, so CloudPull 2.1 also restricts itself to 5000 messages per backup cycle to avoid being throttled. As a result, initial backups can still take a while, but subsequent backups can be over 10 times faster than 2.0.2. Equally important from the perceptual standpoint, CloudPull 2.1 now has an Activity window that tells you what the app is doing and provides progress bars. Other changes include a Check for Updates menu item, improved usability in the Google Accounts preference pane, a text-label switch from Google Docs to Google Drive, pagination of lists with over 1000 items, and retry and backoff logic to make individual backup cycles more resilient to connectivity problems and errors from Google. CloudPull 2.1 requires Mac OS X 10.7 Lion; version 1.5.7 remains available for those running 10.6 Snow Leopard. ($24.99 new, free update, 7.6 MB, release notes)
Smarter Parental Controls
If you've been using the parental controls options in Mac OS X to lock your child out of using a particular computer late at night, but would like to employ a more clever technique to limit Internet access, turn to MAC address filtering on an Apple base station.
To do this, launch AirPort Utility, select your base station, and click Manual Setup. In the Access Control view, choose Time Access to turn on MAC filtering. You'll need to enter the MAC address of the particular computer, which (in 10.5 Leopard and 10.6 Snow Leopard) you can find in the Network System Preferences pane: click AirPort in the adapter list, and click Advanced. The AirPort ID is the MAC address.
