I updated directly over a copy of MyHero II's High Sierra 10.13.6. First, I ran MulitBeast v10.4.0 to just update Clover. Then, I updated the network and USB kexts in /Library/Extensions folder. Rebooted, and I clone the HS disk including copying the EFI folder into the new disk's EFI partition. I downloaded the Mojave installer from the App Store and ran the installer.
I'll be using the Mojave installation only to test and get use to it. I will continue to use HS 10.13.6 until Mojave 10.14.3 comes out with all the major bugs worked out of the system.
Good luck! ..and have fun.
[ Revised*2 : and making short sentence for quick read ]
[Success ] Upgrading from High Sierra (10.13.5) to Mojave [ 10.14.1 public beta 4]
1) Spent "Date and Time " : Almost 4 Weeks
- To find out the stable and better code-quality ( Today, I am standing the beta 4 of Mojave 10.14.1 )
- To find out ( discover ) the short-steps of making "Normal Boot" operation certainly.
2) Pros++ and Cons-- :
++
Much more elegant, better design, and ease of use -- OSx 10.14 (Mojave)
Fine GUI performance of On-Board (HD530) - No need to have GTX1080TI for just GUI making
Good chance to think(find) about the cost-value of HD530(on-board graphic chip) for regular GUI operation
--
Gave-up to use GTX1080TI continuously, Fighting in the dark and amazing steps
Need to have the separation DASD world -- one is Mojave DASD only, the other is MIXED (Win10 Pro and Mojave)
Very Very Tired thru long-long-term testing/installation/detective
Very Poor package content/process for Mojave 10.14.1 public beta 5,but the package of beta 2, 3, 4 are very good.
3) The final goal to establish the Normal-booting on my Hacintosh equipment.
Thru my longterm-heavy testing, I would like to show you as below.
And I am very happy to share these items with all of you.
- I was surprised when I saw many APFS access error ( IMG_210.jpg). Just Few days ago, these error are warning.
The real reason (which force you the safe boot ) is inside - I have found recently.
- It was not difficult to use OSx on my Hacintosh, but now it is so very difficult that I spent much time for testing.
< Tips/Hints are here bellow - thru the content/inside of my Hacintosh definition >
~ The actual content of "64bit Driver , kext-others , kext--patches " in EFI folder -- Picked up from Clover r4700
~ Recommended " Clean-up action before shutdown/initialize of your Mojave system )
It is to use two free-applications [ CClear ( Pro version need pay) and Onyx(Maintenance menu) ]
And Last one is the BIOS setting ( inside of Motherboard ) for saving energy, This is natural but helpful for the Earth.
If the Apple inside coding finds that your Hacintosh is violated these specification, the boot steps is in slow-speed-mode and then time-up --- this is my experience ( not sure that another Hacintosh user can also apply these tips) )
~ OC Tweaker/CPU Configuration -- 181024112104.PDF and 181024112134.PDF
~ Advanced/CPU Configuration -- remains 2 PDF files
~ Hyper Threading Technology -- Should be "Disable"
~ Intel Speed Step -- don't care
~ IGFX on board OC setting ( maximum 1400MHz on my Z170M OC Formula )-- don't care
4) So what now - how/what I am thinking
My impression thru the heavy work for Mojave Installation:
It was the easily maintenance til the High Sierra (HS 10.13.5 ), but after moved in HS 10.13.6 and Mojave I feel that I have moved from the Heaven ( of Hacintosh ) to the Hell .
>> None ( or poor ) of nVidia Web driver - My GTX1080Ti board has already gone
I really think whether alternative PCIex16 GPU ( AMD RX570, Vega 56, GTX780 etc) should be purchased or NOT.
The GUI operation (HD530: Overclocking to 1400 MHz) is so fast that I do not need to buy PCIe graphic board -
Except some Web application (that need some heavy load on GPU) : Ex. Googlemap - route setting
Finaly, I decided to continue the use of my motherboard with best overclokcing (CPU/Cache 4.4GHz,GPU 1400MHz)
>> Saving-Energy Policy ( like Mac Book Pro - even though your Hacintosh is X86 DesktopPC) seems active Mojave inside.
>> Expensive of Intel newer Processor ( i7-9900K, -9700K ), and much more expensive of newer GTX2080Ti
Therefore, it is the signal for moving hand-made-PC ( Hacintosh : by Older chip technology - 12~14nm ) to coming newer 2018 iPad-Pro ( 7nm chip technology ).
Best regards.
