Dell triple boot el capitan freezes on minimize

Hello All,

 

 

I have a dell e6420 laptop which i have setup for triple boot. i just realized that i followed an old guide and thus it might be why I'm having freezes on minimize windows. specifically browser windows.

 

this is what i did:

 

install osx el capitan

created 2 partitions fat

installed windows

installed ubuntu

installed gptsync on ubuntu to keep all partitions sync'ed. 

went back to windows and made OSX partition active so that clover will boot.

 

now everything works fine, but i have a very strange issue.

when i hit minimize, the window freezes half way down and then it goes to the dock. sometimes it just hangs and i have to reboot.

this issue is only on OSX. windows and linux don't exhibit this issue.

 

i thought my issue was related to installing gptsync under linux, so i have removed it after reading other triple boot guides but the issue remains. it seems keeping the partitions in sync is no longer needed.

 

 

Specs:

Dell E6420 

8GB RAM

525 GB Crucial SSD

intel i7 2.8Ghz

1600x900 Display

 

is there a log that i can attach to try and see where this issue is coming from ?

 

thanks

hello,

 

Thank you for your reply. You were the only one to actually have an idea as to what the issue is. I suspected it was a OSX bug as someone i know has a real iMac and is experiencing same issue.

As you suggested I changed my pixel clock and tried different settings. when i brought it down to 1600x900 @ 40Hz the widow doest freeze no more on minimize.

but to me that seems like its excessive. going down to 40Hz from 60Hz.

 

is there any other way  to get this issue resolved ? what am I loosing on my screen to go down to such low pixel clock ?

 

Is this something that reloading the OS could fix ?

 

I Can't believe i'm the only one with a Dell Latitude with the 1600x900 resolution.

 

is it a better option to just load Mavericks ? i have Mavericks running on my ASUS laptop and i really see no reason to keep EL Capitan.

 

Thanks again for taking the time to respond.

It's Dell laptops with Sandy Bridge CPU that have this problem, no other OEMs have the same problem. You are unlucky to be stuck with this not-so-perfect hackintosh here. I will try to find one that has the same problem as you and find out the option needed to fix the problem without lowering refresh rate

Edit: a friend of mine said: create a custom resolution profile, it will have 3 options to choose, CTV or something he can't remember. Pick one and begin trial-and-error. If it fails to boot you can use Safe Mode to remove the custom resolution and start anew
