  1. I’m glad that Apple is the company that it is…
    Anyone can screw up but if they are willing to take ownership and fix it and make it better, I’m willing to wait for it a little.

    Apple people just will not let Apple have shitty software. So Apple can thank us as well as we should thank them for their diligence.

  2. If Apple were to release new hardware in the next few months, such as a tablet, for example, then it would not be surprising that there would be a big OS X update just before, to ensure comparability with all of the new features.

    Keep in mind that the update, however massive, will be mostly replacing, not adding to the existing code of your installed OS.

  4. To be fair, these updates often replace applications and source code – not just add to it. In other words, that 665.7MB might remove 500MB in the update process, leaving something like 165.7MB in new code.

    I’ve never understood why some people look at software updates as proof of a flawed system. Nothing in computer software is perfect and I am more than happy to know that Apple pays a team of engineers millions each year to constantly refine and secure the OS. And that’s my biggest complaint with Linux is that there is no central quality control over the many different flavors floating about.

  5. @Lava_Head_UK and others

    Most bits of an Apple Software update replace existing components with patched new versions; hence, updates even large ones may not increase the footprint on your HD by much. The size of the update reflects to number of patched OS components. The updated OS would only increase significantly in size if features are added or significantly changed.
