Dell Latitude 7490 - Installation Mojave 10.15.x with a dualboot - Support Request

Patched DSDT is in ACPI/patched folder of the packs I had posted (now moved away to avoid issues). If you've not done so, remove it as it would cause your computer to KP.

 

Again, forget about BIOS version, it's irrelevant.

Now I have this error :

I retried with 10.15.5 Catalina and it's still not working. I used the new version of the 7490_Catalina_Clover_Pack_#3.zip

 

Where is "-igfxvesa" ? I can't find it

You type it as a boot argument/option when you go to Clover Options menu at Clover boot screen !

 

Above picture is not a problem at all, it's the normal early info displayed in verbose mode since 10.15.4.

I retry once again step by step and I still having trouble. I have that : 

 

Are you French ? Because, if you're French, it could be easier for me to talk French that english

Forum runs in English only as per our posted rules.

 

No errors either in the last picture you posted; just wait a little, it should get to the black screen with white Apple log + white progress bar before reaching the main macOS installation screen.

When I wait, this happened

And if I wait more, I just have some line with nothing that spawn
