OS X updates are huge files

These days, if all you have is dial-up for email and Internet access, you might as well forget about downloading the latest software update for Mac OS X. This week, Apple released the 10.5.5 client update that took about an hour to download and install on my MacBook Pro using a moderately fast broadband connection.

As noted on tech sites such as MacFixit, installing the standalone combo updater usually results in a smoother upgrade than running the incremental installers which only focus on the ‘delta’ changes between the old and new operating system.

The standalone 10.5.5 client combo updater weighs in at a hefty 601 megs while 10.5.5 server tips the scales at 729 megs. Even the HP Printer Driver 1.1.1 update that was recently released on September 11 requires 405 megs of disk space. Gone are the days you can back up the installation disk images onto a blank CD. Now you need a DVD to accomplish the same task.
