Q: Disk is too slow or System Overloaded ERROR

i think there is no way to fix that problem because it is an hardware limit.If your work is too big for that Mac you need a more powerfull machine.Anyway you can try to freeze some tracks or use Logic Node tryin to distribute the work between 2 machines.Hope this help you. Regards.

It's a bug in logic. It's been there since multicore CPUs came out.

Try putting your fx on a bus/aux rather than on the same track as the instrument.

That way it will trick logic into using a different core for the different tracks.

I've seen this problem on dual quad core CPU mac pros, so it has nothing to do with your CPU performance.

Also if your recording to the internal harddrive whilst playing back audio from it you might run into problems when using bfd2 or addictive drums or any other large sample library type plugin.

In my MacBook pro I took the DVD drive out and put in an SSD for the OS in its place.

I then use the internal mechanical drive for recording and samples etc.

This solved all my issues and made everything so much snappier.

It's dead easy to do too. Infact it works so well I'm thinking about getting a standard MacBook pro (so I can do the same thing again) instead of the retina one.

I'd refuse to buy a retina one until I have seen logic play back  1 instance of bfd2 a few audio files whilst at the same time recording a guitar through amplitube 3. I'm not paying £2000 if it can't do that. (you'll be surprised)

Like I said my old one couldn't do it due to the overloads you mention until I did the DVD drive swap trick.

The retina looks good but, 1/4" thinner is one thing, but having to carry leads and adapters for everything it kind of defeats the purpose!

I would need a thunderbolt to FireWire adapter (which aren't out yet) a FireWire 800 lead and a FireWire 800 to 400 adapter jut to plug my apogee duet soundcard in! ***?

I'd buy a thunderbolt audio interface but their are no mobile ones. The only ones that are out are large ones for the studio (And mac pros don't even have thunderbolt)

It makes no sense, no sense at all!

You couldn't make it up. At least they have dropped the dongle from logic so I can plug my mouse in.

Emagic should release a pc version again. These quarterly decade updates are getting boring!

Where's logic X?

great points Logic Rocks but the bug is in the dealio.... same slow probs ect
