AFAIK, yes but i didn't test it myself.

 

You should first add everything from the first post: Clover folder with kexts (don't forget to copy Yosemite kexts also and add kext-dev-mode=1), config.plist and update clover.

Then in RtVariables make sure you have 0x28 in BooterConfig  and 0x67 (go back to 0x3 right after install) in ActiveConfig.

Download El Capitan and start install. On first reboot, choose Boot OS X Install instead of you usual HDD. 

 

That should be it, but once again, never did it myself because its always easier to spend 30min and have spare USB in case something goes wrong. :whistle:

Is it possible to update an OS X 10.10.5 with the installer app? without booting from USB and install from there?

 

I have seen posts where people said they upgraded from Yosemite to El Capitan using upgrade option.

 

I have always backed up with Time Machine, done a clean install, then restored all of my files and settings from my Time Machine backup.

Hello Guys i have managed to install El Capitan to my 790 with almost the same files of the tutorial of Morpheousman and Polyzargon. I will attached the 790_Clover directory maybe you can expand the tutorial to 760, 780, 755 and 790. Everything is working well even sleep and wake up.  :)

I have also managed to install El Capitan to my E6320 laptop. you can find the tutorial here

 

Her are the files for the 790

I am not sure about it i think it is the DSDT from last year from the 780. I am not a great hacker for that maybe you can compare it.

And i am also sure it will work on a optiplex 990. I will test it on my work my PC is a 990, last year i have installed yosemite on it.

hey using chris111's tool, when the app has finished do you then copy the clover folder over and then do the post install or do the post install then copy the clover folder over

or do you not do the post install 

 

sorry I'm confused

 

Use chris1111's tool to make USB installer. Then inside EFI partition of USB installer, go into EFI folder, you will see a Clover folder. Delete it, then replace with Clover folder from file from guide.

 

Then your USB installer is ready to use to instal El Capitan.

 

After you have installed El Capitan, use latest version of Clover Installer to install Clover boot loader to your Hard Drive. Then go into Hard Drive's EFI/EFI folder, and delete Clover folder again, and replace.

Thanks for help and do I do the post installation like it says in chris111's post

 

 

No, after installing El Capitan, use Guide on page one for post install.  

 

Post install is installing Clover Bootloader to your hard drive. Use setting in guide on page onto install latest version of clover, then delete and replace the clover folder.
