Every time you install a Mac OS X update, a receipt.pkg file for the update is stored in this folder. In certain situations, as discussed in Chapter 2, the OS (especially Software Update) uses these files as a means of knowing that a given update has been installed. Google no longer provides support for older versions than Mac OS X Yosemite 10.10. FAQ Can you install Google Chrome on a Mac? If you want to use Chrome as your default browser, you will need to manually set it to the default browser on your PC as Mac comes out with the Safari web browser pre-installed.

1. The Layers of Mac OS X: Aqua

Mac Os Versions

There is more than one way to think about dividing up a pizza. First, there is the familiar method of dividing it into slices. Alternatively, you could divide it into layers: topping, cheese, sauce, crust. Theoretically, you could also divide it into its basic ingredients: flour, water, tomatoes, garlic, milk. Each method makes a different contribution to your enjoyment of the pizza. The first method (slices) is best when you're getting ready to eat the pizza; the second is best when you are deciding what to order (such as pepperoni with extra cheese); the third is best if you are concerned about nutrition (needing to know the exact ingredients to calculate calories).

The same is true for Mac OS X. There are multiple ways to look at it and take it apart. Each way makes its own contribution to your understanding of the OS. In this chapter, I look at the major ways to 'take apart' Mac OS X. Having at least a minimal knowledge of Mac OS 9 will help, as I occasionally make comparisons between the two OS versions. But even if you've never used Mac OS 9, you'll be able to follow along.

The Layers of Mac OS X: Aqua

Aqua is the name given to what most users think of when they think of Mac OS X: the user interface, the Finder, the Dock, the windows, the translucent buttons, the high-resolution icons, the menus, and all the rest. Many users may never explore Mac OS X beyond its Aqua layer.

From this perspective, a user upgrading from Mac OS 9 will feel quite at home, at least initially. Much still works the same way. You still double-click icons in the Finder to launch them; you still choose the Save command from an application's File menu to save a document; you still open a folder icon to see its contents.

But you will soon notice some significant differences: a new column view, a very different Apple menu, the Dock. I discussed the basics in Chapter 3, when I presented an overview of Mac OS X.

How to Make Handbrake Libdvdcss Workable on Mac OS X El Capitan or Later

If your MacBook or iMac is running on Mac OS X El Capitan or later version and you need to make libdvdcss workable on Mac OS X 10.11 for your Handbrake DVD ripping, you are suggested to prepare yourself mentally. The Handbrake doesn't run as smoothly as the one abovementioned.

Case 1: El Capitan apparently broke Handbrake ripping copy-protected DVDs. Any clue what to do?

Solutions:
1) Disable SIP and reinstall libdvdcss on Mac El Capitan. FIY: SIP means System Integrity Protection, the new security system for OS X El Capitan.
2) Install a copy via homebrew ( a package manager).
3) Move software library to /usr/local/lib instead, which is not protected by SIP.

How to move libdvdcss file to /usr/local/lib?
• Create a new Finder window
• Go to /Library/SystemMigration/History/ through cmd-shift-G (<--copy the path from here also allowed) and manually proceed on inside Migration-some-gibberish/QuarantineRoot/usr
• Copy the libdvdcss.2.dylib file (Cmd-C)
• Apply cmd-shift-G to /usr/local/lib (no copy remember!)
• Take use of cmd-opt-V to move it (not copy) it to this location
• It will ask for your password and should then move it.

Case 2: Current libdvdcss version is 2.8.1 BUT won't install on OS X El Capitan unless it has been installed before upgrading. The problem seems to be that El Capitan does not allow the creation of the necessary folders in usr. If you installed it BEFORE updating to El Capitan then there is no problem. I tried to disable rootless but still no luck

Solutions:
1) Downgrade your El Capitan to Mac OS X Yosemite first and then download & install libdvdcss and OSXfuse on Yosemite before upgrading to El Capitan.
2) Generally, /usr/local can't be found on fresh installs of OS X 10.5 to 10.10. When you update operating system from Yosemite (no /usr/local directory) to El Capitan, /usr/local is generated automatically. If not, there might be something wrong with the El Capitan installer or your system.

The way to fix libdvdcss won't install problem is temporarily disable rootless, create the directory, make sure the 'restricted' flag is not set, and re-enable rootless.
