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, Titans 'Maxwell' and GTX 10x0 "Pascal" graphics cards, you'll need to install the nVidia 10.12.5 Web driver(s) after the 10.12.5 update; when the drivers are updated, the link available in Post #1.
- For M.2 NVMe SSD owners, you will need to update the HackrNVMeFamily kext with
RehabMan's patcher script and installation instructions. See his
Post here.
- 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: see
pastrychef's post on the need to wait for the updates of the Lilu.kext and NvidiaGraphicsFixup.kext.
- For users of on-board graphics, see tonymacx86's
Post #6 in this thread for updates as 10.12.5 breaks HD5xx and HD6xx.
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 10.12.5 - 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) 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 El Capitan, then it should "survive" the update, but check to make sure; and
Re-boot
(Optional for M.2 NVMe SSD owners) You will need to update using
RehabMan's patcher script for 10.12.5. See the installation instructions and this
Post here.
For Nvidia Maxwell graphic cards users (see 2nd and 3rd note above), you'll need to do the following:
Backup your current installation using Carbon Copy Cloner or SuperDuper;
Download the Software Update or use the MAS update;
Run the Sierra 10.12.4 Mac App Store Update - the updater will reboot upon completion;
Upon rebooting, the Nvidia driver will prompt you to update to the latest driver and reboot when its completed it's installation;
(Optional for M.2 NVMe SSD owners) Update your HackrNVMeFamily kext with RehabMan's patch-nvme. See this
Post here.
