Pre Update Notes:
- This update may break some of your Sierra functions, like audio and the nVidia Web drivers.
Make sure you backup first.
- If you're using nVidia drivers for your GeForce GTX 750, 750Ti, 960, 970, 980, 980 Ti and the Titans 'Maxwell' graphics cards, you'll need to install the nVidia 10.12.3 Web driver(s) after the 10.12.3 update >
NVIDIA Releases Alternate Graphics Drivers for macOS Sierra 10.12.3 (367.15.10.35).
- No support for GTX 1070/1080 graphics cards, yet. Still awaiting the a Nvidia compatible driver.
- For Samsung 950 M.2 NVMe SSD owners, you will need to await the update of
RehabMan's patcher script and installation instructions.
- For those who are using the MacPro6,1, iMac15,1, or iMac17,1 system definitions may need to re-apply the black screen fix. Thanks to pantrychef who pointed this out in
Post #14.
Update Procedure(s)
Here's the step by step way to update for those who aren't using the nVidia Maxwell graphics cards. For Nvidia Maxwell card users, see below
Backup your current installation using Carbon Copy Cloner or SuperDuper;
Download the Software Update or Combo Update and run it to update to 10.12.3 - the updater will reboot upon completion;
Upon rebooting into Sierra, you can:
Check to see if your audio is working (If you enabled Realtek on-board audio using the latest MultiBeast for Sierra or
toleda's CloverALC120 script, your audio should be OK),
(Optional) Update to the latest version of Clover,
(Optional) Check to see if your TRIM setting has survived through the update (About this Mac > System > System Report > NVMExpress or SATA/SATA Express) - if not, use the "trimforce" Terminal command
(1); if you've used the "trimforce" command in 10.11.0, then it should "survive" the update, but check to make sure; and
Re-boot
(Optional for Samsung 950 M.2 NVMe SSD owners) You will need to await the update of
RehabMan's patcher script and installation instructions.
For Nvidia Maxwell graphic cards users (see 2nd and 3rd note above), you'll need to do the following:
