Ok so I have dell optiplex 760 with fully functional Yosemite.

 

The thing that nags me is the way the boot screen progress bar acts; it goes really slowly for the first one third and then the screen blinks and the Apple logo vanishes and the progress bar rushes to the end. Then the login screen appears.

 

Although the progress bar problem is present in real macs, the boot screen smoothly transfers to login screen. Is there any way to fix this?

 

Ps: sorry for poor english

What bootloader you use?

oh sorry i forgot.

i use clover, latest version.

 

another thing is that for mountain lion and mavericks i used chameleon and when i had not installed video kexts, there was transition but after installing kexts there was again that blink. With clover (or yosemite) it was present from start.
