Q: Serious lag in LP9/X in Yosemite

For the last couple of weeks 10.10 has been working perfectly on both my 2012 Mac Pro & 2011 MacBook Pro (both running with M4 SSD's as boot drives), however in the last week I started to notice that both Logic 9 & X were suffering from some serious input lag issues where by Logic will lock up when playing back, making editing a real pain.

 

Ie - you play a small section of a vocal to work on timing and it'll lock up and either play the half-beat cycle loop repeatedly or carry on playing if cycle isn't engaged. What's worse is that these lock ups appear to be getting longer and longer before it springs back to life, manically catching up with the commands I've been pressing when it left orbit.

 

Weirdly enough whilst it was in lunar orbit I opened up iCal to update some stuff and when I went to quit (cmd Q) Logic suddenly bounced up and down asking if I wanted to save and iCal remained open, implying that these lock ups are system wide not just within Logic and it hadn't noticed iCal was the app in focus despite me adding dates into it. When I open the activity monitor, nothing is kicking up a fuss or hogging loads of CPU.

 

Any ideas? Also is there an easy way of reverting to 10.9 from a bootable backup short of having to reinstall everything? I'm guessing the Migration Assistant won't see the backup as it's a newer OS...

    There are known issues with Yosemite and Logic (and other apps) and certain Macs/hardware configs..at this time hence the Tips page here on not updating to Yosemite......  yet!

     

    So, to roll back...

    This is for rolling back from the public beta but it works the same way with the final release too.

    I'm almost tempted to use one of my external drives for a test... almost.  :-)

    Maybe it's my imagination but does this seem to be happening more on computers with SSD's?

    Actually I'm seeing more problems on Macs that have Retina screens... but then the same seemed to apply initially with Mavericks too....

     

    Prospective iMac Retina owners.... You have been warned!

    I read somewhere that doing a clean install of Yosemite and then restoring their backup seems to be helping people with (non pro-app related) freezing and lock ups - has anyone tried it?

    My MacBook Pro's Logic X has been seriously affected by Yosemite. Now I can't work on a normal sized project without freezing all the tracks. That's simply horrible!

    Hi Everyone,

     

    Yes, I'm having this same problem. I've had it before but it's getting pretty bad. I have a mac mini bought in June. On Mavericks everything was kicking butt. Tons of puggs, audio files, etc... running very well.

     

    going to Yosemite has been trouble apparently with the Lag as ben mentioned. Playback not responding to space bar. It's a total drag. My CPU usage looks fine so I'm kind of puzzled. Btw this is intermittent. Sometimes it will happen with a almost clean session (not lots of pluggins or tracks) and other times my huge sessions with tons of data work fine.

     

    In addition to this, I've found that scrolling on my wireless mighty mouse, even when there is no playback, is very choppy and slow. Almost unusable. I would really like info from Apple about this, but unfortunately their idea of customer service is providing a forum for us to just figure **** out on our own.

     

    A WORK AROUND -

     

    I have noticed that one way to stop playback pretty consistently during these "orbits" is to use a DAW remote app on your phone. I'm using "DAW remote" with logic 9 on a iPhone 6. When I have that synced with the logic and playback won't stop, clicking stop on the DAW app will stop it in it's tracks. Good to have a workaround, but need the stuff I spend lots of $$$ on to work properly, thanks.

    There's less people to pay when there's no official support available online, Apple is lucky to have a helpful user base, they're trained their customers well. I'd like to see what would happen if every person that answers questions regularly on these Forums took a two or three day vacation from replying to posts.

     

    This is reminiscent of the problem that plagued Logic users a while back, newer graphic routines (especially with hi-res Retina displays) are not 100% compatible with Logic's current method of displaying graphics.

    Apparently this affects some machines with certain GPU's more than others.

    Indeed...

     

    However....

     

    if you have a Retina screen...

     

    Try turning off Automatic Graphic Switching..... (AGS) as several people have reported some success and a degree of improvement after doing so...

     

    MacBook Pro and MacBook Pro with Retina display computers: How to set graphics performance - Apple Support

     

    Note: If you are using a second monitor... even if you uncheck AGS it is still activated automatically unfortunately so you won't get any possible benefit. So to effectively test, unplug any secondary monitors....

    Question:  Do all Retina screen machines have dual graphic processors. (one being exclusively hardware based, correct?)

    I'm not absolutely sure but I believe so.. They have an 'onboard' Intel based Graphics Chip and then the extra Nvidia/AMD card....

     

    Even some non Retina MBPs had/have dual graphics systems.. My old 2009 non-retina had dual systems.. The idea being under battery power it used the onboard one to reduce power consumption.
