Can confirm 10.14.1 is installed and running fine on my MacBook5,1 (late 2008 unibody, upgraded to 8GB RAM and a 128GB Crucial SSD formatted HFS+ journaled). Only hiccup was that I had to use the "Force Cache Rebuild" function – see all steps as listed below.
Here are the steps I followed to update from 10.14.0 to 10.14.1:
1. Downloaded DosDude1's latest macOS Mojave Patcher (version 1.2.3).
2. Launched the patcher app, selected "Download macOS Mojave" from the Tools menu, and waited for the full 10.14.1 installer to finish downloading from Apple's servers.
3. Plugged in my external USB drive and let the Patcher do its thing – reformatting the drive and copying the patched Mojave installer onto it.
4. Restarted my MacBook from the USB drive, and ran the new installer overtop of the existing 10.14 install on my internal SSD (still formatted HFS+ journaled). Installer completed after about 33 minutes and initiated a restart. I held down the option key and again booted from the USB drive.
5. Ran the macOS Post-Install utility for my Mac model. Clicked the reboot button.
6. MacBook rebooted several times. After showing the kernel panic screen i.e. "Your computer restarted because of a problem...please press any key" and rebooting several times to no avail, I held down the option key to again reboot from the USB drive.
7. Re-ran the macOS Post-Install utility for my Mac model, and this time clicked the "Force Cache Rebuild" checkbox and clicked the Reboot button. That did the trick, and within a minute or two the Mac had restarted successfully back to the sign-in screen. (Total elapsed time for this upgrade install was about 40 minutes.)
BUGS I HAD NOTICED IN 10.14.0:
-File and folder icons will periodically stop refreshing on the Desktop. Restarting usually resolves this issue.
BUGS/ISSUES I'VE NOTICED UPGRADING TO 10.14.1 (other than known sidebar shading issue):
-Night Shift was disabled after the update, but I fixed this by reinstalling the Night Shift patch via DosDude1's Patch Updater app.
-My computer was renamed to the generic "MacBook", but I fixed this by re-editing the name in Sharing preferences.
-10.14.1 seems to have resolved a small issue I experienced under 10.14.0, where I'd notice my file and folder icons weren't loading on the Desktop. That seems to now be resolved.
-I tried playing a new DVD but it didn't work. The built-in optical drive did recognize the DVD media and launched the DVD Player app, but DVD player would not autoplay or respond to my clicks to start playing or enter the main menu. (FYI: The same DVD played fine on a supported Mac running Mojave.)
-The MacBook does seem to slow down after regular use, or when I put it to sleep overnight instead of shutting it down. I think this was present under 10.14.0 but I can't be sure as I was shutting the computer down after each use. Now I'm putting the machine to sleep more and am noticing the problem more often. The only way I can temporarily correct this is by doing a restart, or using Memory Clean to do it's thing...which seems to sweep away some of the cobwebs.
-iCloud seems to not update from this MacBook quite as often as from my other devices. I'll often make changes on this MacBook to my Calendar, or iCloud Drive, or other apps that sync with iCloud, then put this Mac to sleep, only to notice that those changes haven't copied over across devices. At one point I used Terminal to reset my iCloud Drive, which successfully got things back in sync, but then left me with a bunch of duplicate files to sort through.
-My birthdays calendar has periodically stopped showing up in Calendar. It works fine with my other devices — syncing birthdays from my Contacts to my Calendar — but I recently noticed it suddenly stopped working on my MacBook for a week or so. And then one day I awoke the MacBook from sleep and the birthdays appeared again. So I'm not sure what's going on with that.
Otherwise everything else is behaving as it did under 10.14.0. Will update this post if I discover any other issues. The most important thing is that I can now view all the latest Emojis
***UPDATE: After installing 10.14.3***
Upgrade procedure went smoothly and was the exact same as outlined above for 10.14.1. One nice improvement is that Textedit now works in dark mode. Under 10.14.1 it had continued to use black text on the white background, but now it's white-on-black. Will update this post with any bugs as I discover them...
