HP Pavilion DV6187ea near perfect installation...?

Question

Hello all!

 

After quite some time of trying to figure out how I could possibly update my Snow Leopard installation

and have every major hardware operational I achieved my goal using Niresh's Lion distribution. The only

hardware I replaced was the WiFi adapter with an Atheros AR5BXB112. I wasn't fully satisfied

and tried the Yosemite distro as well...

 

However I still face a few "secondary" issues and was wondering how I could possibly resolve them 

and have a perfect system.

 

So to be more exact :

a ) my graphics board is regognised by the system as a GeForce Go7400 128MB which is correct,

however I cannot alter the resolution to a higher value than 1024*768, neither can I achieve a normal

frame rate which causes a lot of flickering

b ) the "Sound" appears to have poor quality (as if my speakers are blown)

c ) my system is recognized as a Macbook Air in "About This Mac -> More Info", however when I press

"More Info" it appears as MacBook 3,1 (which I assigned using Chameleon Wizard) and when I reach

the logon screen I get a message to install a bluetooth mouse...

d ) can I upgrade to 10.10.3 without a problem or should I stay where I am?

 

Thanks in advance for all responses.
