clipping sound on new iMac when Logix X is running

System Preferences -> Startup disk

...or hold down the option key on bootup and choose your startup disk....

Cheers guys!

So... quick question for anyone who knows about booting from an external disk.

I'm not too hot on this external / bootable drive stuff.

Can I not just create a bootable disk from an 8GB usb stick and use that and leave logic pro x on the FD or would LPX HAVE to be an external drive with everything on it too?

:-/

The aim of booting from an external HD is so that the Fusion Drive is not accessed at all. If you simply boot from an OS X stick and then access LPX etc... on the FD... then the FD would continue to be used.. hence the problem with that idea...

So, the answer is no.. You should create an entirely new system disk with everything you need to use on it and not use the FD at all.

Note: The 'stick' method or any of the other variants that needed to access the FD for other programs/data etc... were tested and did not work.... for the reasons given above.

Ahhh... I see.

So if I was to make a new "Macintosh HD" on my thunderbolt drive from a Time Machine backup then I'm bypassing the whole Fusion Drive system, right? Which is the workaround until an official fix comes out.

I get it. Doh moment. Hahahaha. Sorry been a crazy weekend and on downtime brain wise! Haha.

Thanks :-)

I actually use a Clone program such as Carbon Copy Cloner or my personal favorite SuperDuper! to clone the current system drive on the the Ext drive because i don't trust Time machine for such things but yes, thats the same basic idea 🙂

I like the idea of the workaround because it seems to be producing great results, and I don't want to sound cynical in asking this, but do you guys think Apple will actually fix this?

Because I don't want to waste money spent upgrading to a FD plus that spent on an ext HD. I'd rather swap my computer out for one sans FD.

What do you guys think?

jwweeks,

Frankly I believe Apple will resolve the issue because it is in their best interests to do so but....

..and as just a personal opinion....

I truly don't think a Fusion Drive is something I would purchase irrespective of this issue or not

I might be pursuaded to buy a real SSD as my System Drive though the Cost to GB ratio compared to a fast 7200rpm HD connected internally to the ATA serial bus.. is still a little 'rich' for me.. and I'd want a fairly large sized one.. Certainly no less than 500GB... so that ups the cost... but the Fusion Drive, to me, is more a kind of halfway house doesn't warrant it's extra cost... and places a load upon the CPU that outweighs any benefits it brings to drive performance, due to the way it works.. To me its not much more than a glorified Extra Large Cache..... with some 'clever' software running/managing things..

So, I would stick to either a good sized SSD as my system drive.. if money wasn't of concern... or stick to the fast internal 7200rpm Mech HD and spend the extra money on a good Glyph External FW800 HD or two.. for my Audio work...

Hey Pancenter,

Thanks for the reply. When I open Audio MIDI setup I just have the Built-In Mic as an input option - no sign of a digital input.

If you still have a computer would you try an experiment for me.

In Audio-MIDI setup set the Mic as the Input set the Format to 48,000 hz 16-bit.

After that's done go to Logic and set the Input to Mic or Built-In (whichever one appears) Outout to Built-In.

Do you still get the noise?

Ok.. Update.

I have restored my iMac using Time Machine. Made sure it was backed up before hand.

I have split my thunderbolt drive and called 1TB of it Mac HD. I have reinstalled onto there and am now running off there 100% bypassing the fusion.

First of all. SUCESS!!!!!!

I have been playing ALL my Logic Pro X sessions for over an hour now and no pops, no clicks, no ANYTHING out of the ordinary running completely off the External Thunderbolt drive.

Secondly, The only difference i see in speed is when you switch the iMac on it is about 1/3 slower to get running but considering it only took 20 seconds to boot up anyways, who cares?!?!

Thirdly, SUCESS with the internal audio. I NEVER had pops or clicks internally but couldnt route the audio through the saffire without the issue of complete cut out occuring. but now it works flawlessly.

Main thing is that this cloning the drive and running external works for now and more importantly i can record (which I have tested and no issue what so ever!)

Once Apple deal with out a fix (which will be tomorrow knowing my luck! hahaha) I will switch it back.. but for now my Saffire Pro 14 is running as smooth as you like with Saffire Mix Control software.

One happy JP.. for now! haha

Hey Johnpaul..

Good news indeed!

and of course...

Thank you.... for letting us know what worked for you.. Such feedback is always welcome and useful in regards to helping others who may have the same issue...

Cheers!

Someone should let the people at Focusrite know this.

I never get the crackling noise when using the built-in mic, only when using an AI.

I owned a Focusrite Scarlett 18i20 for a while but ultimitely sent it back due to what I thought was faulty hardware (because who would question the FD right?).

Now I'm borrowing a friend's little Audiobox by PreSonus and getting the same crackling result.

But again, no crackling from the built-in mic.
