Optional QuickDraw & Print Manager headers support in OS X 10.7+ ( requires FB 5.7.7+ )

Optional QuickDraw headers support in OS X 10.7+ ( requires FB 5.7.7+ )

QuickDraw and Print Manager Headers are missing in 10.7 and higher

In OS X 10.7 and higher Apple removed the Quickdraw headers and in OS X 10.10 removed some Print Manager headers.
FB5's runtime requires the Quickdraw headers ( located in the Quickdraw framework ), so any SDK selected in Build Settings must have the Quickdraw headers installed in it.

Starting in FB 5.7.11, build settings shows only the installed SDKs while older FB versions showed all possible SDKs even if they were not installed

Apple's 10.6 SDK has the Quickdraw headers/framework but if you want to use features in 10.7+, a Quickdraw framework must be added to the SDK directory ( either 10.7, 10.8, 10.9, 10.10, 10.11, 10.12 or 10.13 SDK ).
Which SDKs are upgraded this way is entirely up to the FB programmer but only the one being used needs to be fixed.

Generally it is best to use the latest SDK ( 10.11 as of August 2016 ) and add the Quickdraw headers to it.

After updating the latest SDK with Quickdraw headers and Print Manger headers, the 10.6 SDK can be set aside and saved and only the latest SDK used in Build Settings

Only one(1) SDK is required for typical FB5 operation:
- the latest SDK updated as described below or
- the 10.6 SDK

Fixing the missing headers issues

Adding the support for both issues( i.e. absence of Quickdraw and Print Manager headers ) requires the user to intervene and make one-time changes for the desired SDKs ( i.e. either 10.7, 10.8, 10.9, 10.10 or 10.11 ). SDK changes should be made carefully. There are two options for making the SDK changes:

The automated method is the FixSDK app. To run it, use the FB Help menu and select the FixSDK.app option
The manual method: Manual Method Instructions/Description

This optional process is only required if you need to build against 10.7 SDKs and higher. In other words, if the 10.6 SDK's limitations don't pose a problem for your project, no changes are required.

You will have to repeat the headers updates after any Xcode update

Since Apple's recent OS X and Xcode updates don't include the Quickdraw framework, FixSDK, or its manual equivalent, should be included in the normal Xcode update cycle but otherwise only needs to be run once for each SDK.

Finding and installing the OS X 10.6 SDK

Both manual and FixSDK approaches REQUIRE a copy of the OS X 10.6 SDK. It may be found here OS X 10.6 SDK

To install: Drag a copy of the 10.6 SDK in the Finder to the directory within the Xcode.app as follows:

Control-click( or right click if available ) Xcode.app
Choose Show Package Contents
Navigate to: Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/
Drag & drop the MacOSX10.6.sdk in the SDKs directory.
