Reports on macOS 10.14 installs from Mac Pro/Radeon RX 580 owners
I've added the first 5 Mojave upgrade reports to the page of Sapphire Radeon RX 580 cards in Mac Pros (2009-2012) page. Jim's report was updated with confirmation (screenshot) of his Mac Pro bootrom version after the update and notes on his 2nd Mac Pro/RX 580 Mojave install - both he said upgraded from 10.13.6 to 10.14 (including firmware update) with only the Radeon Pulse RX 580 card installed. Updated Matt's report to note he was finally able to get the firmware updated/Mojave installed with only a Radeon RX 580 in the Mac Pro.
Apple support article on installing Mojave on 2010-2012 Mac Pros   [= Skip =]
(Note some Mac Pro 4,1 (2009) owners have updated to Mac Pro 5,1 (2010-2012) EFI.)
Apple posted a new article Install macOS 10.14 Mojave on Mac Pro (Mid 2010 & Mid 2012), that says first have macOS 10.13.6 installed, no FileVault, and this note on compatible Graphics cards:

" These specific third-party graphics cards are Metal-capable and compatible with macOS Mojave on Mac Pro (Mid 2010) and Mac Pro (Mid 2012):
  • MSI Gaming Radeon RX 560 128-bit 4GB GDRR5
  • SAPPHIRE Radeon HD 7950 Mac Edition
  • NVIDIA Quadro K5000 for Mac
  • NVIDIA GeForce GTX 680 Mac Edition
Some other third-party graphics cards* based on the following AMD GPU families might also be compatible with macOS Mojave on Mac Pro (Mid 2010) and Mac Pro (Mid 2012):
  • AMD Radeon RX 560
  • AMD Radeon RX 570

  • AMD Radeon Pro WX 7100
  • AMD Radeon RX Vega 56
  • AMD Radeon RX Vega 64
  • AMD Radeon Pro WX 9100

If the graphics card in your Mac Pro isn't listed above, you need to install one that's compatible with macOS Mojave. If you need additional help, contact Apple Support.
* Third-party graphics cards vary, so you should check with the vendor of your specific graphics card for compatibility details."
If any Radeon RX 580 owners upgrade to Mojave, send a report to for adding to our page on Radeon RX 580 in Mac Pros. (Reports on other graphics card models are also welcome of course.) Thanks!
macOS Mojave 10.14.1 (beta)
Apple's developer releases page had macOS Mojave 10.14.1 (18B45d) released a day after 10.14.0. (As of Oct. 1st, 2018 they finally added "beta".)
macOS Mojave released
Apple has a press release that macOS Mojave (18A391) is available now. (Requirements, notes to make a backup, etc. in Upgrade to macOS Mojave page.) See below for related support articles. (They've also added a macOS Mojave discussion forum.)

Reported Mojave Problems and Tips
Also see macOS 10.14 Mojave Forum posts on Problems and Tips, including no Wi-Fi hardware installed, problems with App Store, Time Machine backups failing, and More.

Reminder on OWC Aura SSD Firmware update (not Aura Pro)
I had posted info on this (beta) firmware update last December (page revised in late Feb. 2018) and added on the Storage page, but posting a reminder after I saw a thread in the Mojave forums on problems installing Mojave on a MacBook Pro with Aura SSD. A later post from Alfonso mentioned an Aura SSD firmware update solved the problem. Although the URL is different, the update page has the same info. (Mentions fixes for macOS 10.13 installs, Hibernation and cold booting. Same models listed - OWCSSDAB2MB02, MB05, MB10, MB02K, MB05K, MB10K.) I assume SSDs shipped after the update was posted already have that firmware.

Although the above firmware update is not for the 2013 Mac Pro Aura SSDs, OWC has a page about Aura for 2013 Mac Pro: 10.13.4 and Later Install Issue that includes 2 workarounds for those SSDs.

Here's their SSD Firmware Updaters for other models. If you need help, contact OWC support.

(Also saw posts on install problems with other 3rd-party SSDs like Samsung EVO.)

Little Snitch 4.2.1 (bug fixes/improvements)
Another update to Little Snitch. Info from the 4.2.1 release notes
- Improved support for Dark Mode in macOS Mojave.
- Added back the ability to use the dark appearance of Little Snitch Network Monitor on older system versions (macOS High Sierra and earlier).

Bug Fixes
- Fixed an issue that caused an alert to be shown for an invalid code signature for the App Store on macOS Mojave for some users. There was a bug that prevented Little Snitch from automatically updating the code signature of existing rules when appriopriate. See the Little Snitch help chapter Applications that change their bundle identifier in an update for details about this mechanism.

- Fixed a bug where duplicating a rule in a subscribed rule group would create the duplicate rule in that rule group. The new rule would then be a protected rule that could neither be deleted, nor edited.

- Fixed rule group tags not being shown in "Effective in all profiles".

(Little Snitch 4.2.1 runs on macOS 10.11 to 10.14.)
DisplayLink USB Software for macOS Mojave v5.0 Issue with 2018 MacBooks
FYI: The DisplayLink macOS page added this note on v5.0 problems with 2018 MacBooks:
"Issue with MacBook 2018 models with 10.14 Mojave
MacBook 2018 models (based on the Intel Coffee Lake chipset) running macOS 10.14 can experience black extended display(s) with only mouse cursor. DisplayLink driver v4.3 Beta 6 stays available to force an AirPlay extended display on these machines until a fix is distributed."
(Earlier post on driver v5.0 from Sept. 24th follows)
The DisplayLink macOS USB Software releases page now has a Sept. 24th dated v5.0 for macOS Mojave. (On Sept. 12th they posted v4.3 for macOS 10.11 to 10.13.6 and a beta v5.0.)

(Update: On October 9th/10th, 2018 they posted new drivers for Mojave (v5.0.1), v4.3.1 for High Sierra/Sierra/El Capitan, and v3.3.1 for OS X 10.10.x Yosemite .)

tvOS 12.0.1 released
Apple has posted tvOS 12.0.1 (build 16J380). Release notes say "This update includes general performance and stability improvements." (Link in release notes for "Aerial screen savers" is still incorrect as of post time.)
