Me (and many other people) experience eye-ache from new Macbooks (and windows machines).
I have spent two years of trial-and-error and found that installing macOS Mavericks on my MacBook (pro 13 late 2013, Intel Iris 1536 MB) resolves the issue of eye ache completely. (it is believed that newer systems use harsher version of temporal dithering that causes of a certain group of indivisuals eye aches).
I cannot stay at Mavericks because of software support and security issues, so the only thing is an issue now:
How can I take drivers from Mavericks and install them on Catalina? (I tried replacing .kext in /System/Library/Extensions with old files but it didn't work).
I am having issues with VoodooInput. It loads fine, no errors or KPs, but movement is erratic. It seems when I am moving the cursor with my index finger and then try to click with my thumb, the cursor will shoot to the bottom of the screen, causing erroneous clicks and a lot of headaches. Sometimes it shoots to the top instead. Sometimes it performs as expected. It's unpredictable.
I have used VoodooI2C + VoodooI2CHID instead, and they work perfectly fine, but unfortunately they cause KPs. Plus, I like that VoodooInput is a singular kext. This is why I am trying to see if there's any way to fix this issue.
Unfortunately, this project has come to a halt, at least for now. I don't have enough time to work on the project and it's lacking behind, so please don't use it for configuring OpenCore, it will produce broken configuration files.
I will leave the source code on GitHub, so in case someone wants to take over the project, they can.
MacOS does not support natively the keyboard backlight for non-Apple hardware.
I wrote an open source Kext project (ClevoService) to perform this task on Clevo laptops.
It's fully working on my Clevo P9XXEN_EF_ED laptop with Mojave (18G95) and it should works on many other Clevo laptops.
If you own a Clevo laptop with full color backlight keyboard, take a look at:
The big advantage is that the backlight function is fully controlled from the numeric keypad and it's saved between boot/reboot and sleep/wake.
You can change color, backlight level and ON/OFF.
For the installation, download the kext from release page and follow the instruction given in the GitHub repository.
I can not manage to install Catalina on this legacy Asus machine that runs Mojave fine. When the installer boots up, DiskUtility does not see the internal hard-drives, neither the master SATA one or the the slave, ATA one. I have discussed this already on the Clover section with Slice, he told that some kext seems to have changed from Mojave to Catalina, he told me to use IOReg. Since then, I have postponed my work on Catalina due to the issues regarding the Mojave supplemental updates.
I have decided to start a new topic in here, due to visibility reasons and some new turn. The latest version of the dosdude1 patcher for unsupported Macs, discussed on Macrumors forums, patches the installer so that DiskUtility sees the internal hard-drives, I am able to install Catalina but, on first boot, the OS gets into a kernal panic with the message ”still waiting for root device”. I have searched online for this error, I have found Information regarding previous macOS versions with solutions that seem to have little to no relevance for the present issue.
Before installation finishes, I receive a message like ”Installation finished on Macintosh HD Data”, instead of ”Installation finished on Macintosh HD”. I admit this split between the two in Catalina still confuses me, perhaps this is how it was suppose to be? Perhaps something that was suppose to end up on Macintosh HD ends in Macintosh HD Data?
I admit the DVD-Rom and hard-drives are wired kinda of weird by some guy in a PC service, he said this is the optimum combination, something the ATA hard-drive is slave to the DVD-Rom. Perhaps this causes confusion into Catalina? On Mojave this configuration was fine.
Probably the solution suggested by Slice is the best, to replace one or more kext from Catalina with the Mojave versions of them. I do not know yet how to identify and replace them. If any other solutions seem possible, I am open to them.
