1. HOW TO USE: MACOS SIERRA PATCHER TOOL FOR UNSUPPORTED MACS

2. 1. INSERT YOUR DESIRED USB DRIVE, OPEN DISK UTILITY, AND FORMAT IT AS MAC OS EXTENDED (JOURNALED).

3. 2. OPEN THE "MACOS SIERRA PATCHER" TOOL, AND BROWSE FOR YOUR COPY OF THE MACOS SIERRA INSTALLER APP.

4. *ENSURE THAT THE TOOL SUCCESSFULLY VERIFIES THE APP.

5. 3. NEXT, SELECT YOUR USB DRIVE IN THE TARGET VOLUME LIST, AND CLICK "START OPERATION."

6. 4. WHEN THE OPERATION COMPLETES, BOOT YOUR TARGET UNSUPPORTED MAC OFF THE USB DRIVE YOU JUST CREATED. Note: Only perform steps 5 and 6 if you intend to do a clean install. Otherwise, you can simply skip these steps and install to your volume containg a previous version of OS X, and it'll do an in-place upgrade.

7. 5. WHEN THE INSTALLER BOOTS, OPEN DISK UTILITY.

8. 6. SELECT THE DISK OR PARTITION YOU WANT TO INSTALL ON, AND ERASE IT, ENSURING TO USE MAC OS EXTENDED (JOURNALED) AS THE FILESYSTEM TYPE. IF FORMATTING AN ENTIRE DRIVE, ENSURE GUID IS SELECTED.

9. 7. INSTALL MACOS NORMALLY ONTO THE DESIRED VOLUME.

10. 8. WHEN THE INSTALL COMPLETES, REBOOT BACK ONTO THE INSTALLER DRIVE. THIS TIME, OPEN THE "MACOS POST INSTALL" APPLICATION.

11. 9. IN THE APPLICATION, SELECT THE MAC MODEL YOU ARE USING. THE OPTIMAL PATCHES WILL BE SELECTED FOR YOU BASED ON THE MODEL YOU SELECT. YOU CAN ALSO SELECT OTHER PATCHES OF YOUR CHOOSING.

12. 10. SELECT THE VOLUME YOU HAVE JUST INSTALLED MACOS SIERRA ON, AND CLICK "PATCH." WHEN IT FINISHES PATCHING, CLICK "REBOOT". IT MAY SIT THERE FOR A FEW MOMENTS REBUILDING CACHES BEFORE REBOOTING. -- IF FOR SOME REASON THE SYSTEM FAILS TO WORK CORRECTLY AFTER REBOOTING, BOOT BACK INTO YOUR INSTALLER DRIVE, RUN THE POST INSTALL PATCH AGAIN, AND SELECT "FORCE CACHE REBUILD" BEFORE REBOOTING. THIS ISN'T NECESSARY UNDER MOST CIRCUMSTANCES.

13. 11. WHEN IT REBOOTS, IT SHOULD NOW BOOT INTO A FULLY WORKING COPY OF MACOS SIERRA. Updates: Updates are now patched using a new method installed with the post-install tool. However, if you do not have this patch applied, you can follow the method below to install it manually.
