Mac Developer Program

Pre-Release Software

Receiving pre-release OS X software is an exclusive benefit for all members of the Mac Developer Program. Access to pre-release software allows developers to incorporate the latest technologies into their development, test for compatibility, and report bugs.

Get the Latest Mac Software

Mac Developer Program members can access a range of pre-release Mac software, including OS X, OS X Server, development tools, SDKs, and more. If you are already a member, you can access pre-release software by signing into the Mac Dev Center.

Bug Reporting

Apple appreciates the efforts of our developers who help us discover and isolate bugs within our products. During the testing of pre-release software, we encourage you to submit bug reports and enhancement requests on Apple products and track these submissions using the Apple Bug Reporter.
