[lubuntu-users] Lubuntu 16.04.1 Live causes overheating in a MacBook Pro C2D

[scrooyahoo at riseup.net]

Yesterday I ubgraded 'The Thing' to Capitain.  That was the longest 30 
minutes of my life... It actually took about 6 hours.

I'm still amazed how hot this machine gets.

Thanks for these tips (specially the grub partition tip) I'm now making 
notes and trying to figure how and what. I now think that i can figure 
it out, or at least i know that i can keep OSX alive.

I really had no idea that OSX would throw up so many specific rules.

I'll keep the OSX as 1st partition
then place the 10MB partition for grub

And then the GNU/Linux stuff.

I'll burn El Capitain on a CD just in case i really mess up :-)

I hate what Mac does when you enter the display corners in Capitain that 
combined with the weird touchpad behaviour causes a lot of 
frustration...

I hope I can now make a cute LXDE based desktop on this Mac.


Thanks!
