1j1 Posted February 2, 2013 Share Posted February 2, 2013 Hello, I upgraded to mountain lion a little while ago and have been experiencing lag issues, freeze issues and just general issues with logic that are a massive block to my work flow. I've got some tracks to finish for a label and at the risk of sounding like a primadonna, I can't work like this! I have done some reading online and apparently you cannot easily downgrade from ML to SL. You cannot use time machine to install SL and then restore files from a ML system. I'm pretty sure you have to do it all by hand (which is quite irritating). I'm just wondering, I have also read somewhere that you cannot copy over your library from ML to SL, due to some of the file types being different. Obviously, if this applies to logic library files then this is a problem for my many user sampler instruments and channel strip settings. Does anyone know if you can copy over your logic library files/settings etc from ML to SL? I'm hoping that the file types are the same for logic between systems. If anyone has downgraded from ML to SL and has any advice this would be much appreciated. Thank you Link to comment Share on other sites More sharing options...
redlogic Posted February 2, 2013 Share Posted February 2, 2013 Did you clone your Snow Leopard drive before upgrading to Mountain Lion? Link to comment Share on other sites More sharing options...
robinloops Posted February 2, 2013 Share Posted February 2, 2013 I have not, but I tried to do it with a mac that was purchased with lion. It turns out that if it came with lion pre-installed (even a refurb that originally had leopard) it can't be done. As far as downgrading one that was upgraded from leopard goes, I am fairly sure you have to start over from scratch with a leopard install. You can use the original discks that came with your computer to do it or you can buy a standalone install disk of snow leopard upgrade disk, for $30 (if you don't have the installation disks). I beleive I came across forums of people that successfully downgraded but it was a crazy complicated process... Apple is just not setup for downgrading... But first: Do you have all the most recent updates for Lion? It was a bit glitchy for a while but has gotten really stable. Link to comment Share on other sites More sharing options...
1j1 Posted February 3, 2013 Author Share Posted February 3, 2013 Did you clone your Snow Leopard drive before upgrading to Mountain Lion? Stupidly no (otherwise I wouldn't have a problem ). Silly me for assuming that apple's new "most advanced operating system in the world" would A: work or B: be backwards compatible (sorry, that was quite facetious, it's not directed at you but apple; this is pissing me off). Apple is just not setup for downgrading... Yup, seems a tad unreasonable. Feel like they should have warned me. But first: Do you have all the most recent updates for Lion? It was a bit glitchy for a while but has gotten really stable. I am using both the latest versions of Logic and ML, but still experiencing issues. I think it's only with some third party plugins, but plugins that I use all the time AND plugins that worked 100% fine with SL. I'm under applecare so might call up and see if I can get some advice. Please keep comments + advice coming though. Link to comment Share on other sites More sharing options...
peachboy Posted February 4, 2013 Share Posted February 4, 2013 I downgraded back to SL from ML. (For the record though, my system was originally installed with SL before I made the error of upgrading to ML.) I wiped my system and re-installed from scratch. Because it's a dedicated music system the only elements I needed to copy over from my backup drives were the Logic projects, and the various different applicable elements within the Library folder, specifically Channel Strip settings, Sampler Instruments, etc. i.e Don't copy the entire Library folder - just the stuff you need.

1j1 Posted February 4, 2013 Author Share Posted February 4, 2013 Peachboy, I've got a few questions: Firstly: did all of your files copy over ok? I have a lot of user settings and sampler instruments that I want to/need to keep: Channel Strip Settings, instrument settings, plugin settings, sampler instruments; were all of these ok for you? Have you experienced any problems since? Secondly, were you on Logic 9.1.8 and ML 10.8.2 and having problems, before you switched? Third, when did you have problems? Was it just with third party plugs? Fourth, were you running 64bit or 32bit logic? I spoke to someone at apple and they said that some files made on ML MIGHT not work on SL (MIGHT and they couldn't tell me which ones MIGHTN'T either). Before I was having problems with all plugs logic and third party, but then with the update 9.1.8/10.8.2 it was just third party. I am also running in 32bit mode; therefore, they also suggested that the problem might have been that I needed to upgrade my third party plugs, and/or the problem was that ML is 64bit and Logic is 32bit and therefore I should use 64bit. Just trying to figure out which is the best way to proceed. I might try 64bit + updating plugs and see what happens, but really, I'd just like to not have this headache and be able to go back to nice, easy SL (if everything copies across fine). Thank you for your time + input. J Link to comment Share on other sites More sharing options...
Simon Morrison Posted February 4, 2013 Share Posted February 4, 2013 Logic Pro 9.1.8 is very stable under Mac OS X 10.8.2 (Mountain Lion). Most 3rd party plug-ins are Mountain Lion compatible, and many are now 64-bit. Rather than downgrading the OS, I would suggest checking for updates to your installed software and plug-ins. With 8 GB of RAM I would definitely run Logic in 64-bit mode. What plug-ins are causing problems? Link to comment Share on other sites More sharing options...
peachboy Posted February 5, 2013 Share Posted February 5, 2013 did all of your files copy over ok? I have a lot of user settings and sampler instruments that I want to/need to keep: Channel Strip Settings, instrument settings, plugin settings, sampler instruments; were all of these ok for you? Have you experienced any problems since? Yes they worked okay. I copied over individual folders like the Channel Strip settings, plugin settings etc, rather than the entire Library folder. Haven't experienced any problems since. Secondly, were you on Logic 9.1.8 and ML 10.8.2 and having problems, before you switched? I'm not quite sure on the exact version numbers to be honest and I don't seem to have a record of them at the time of downgrade. Third, when did you have problems? Was it just with third party plugs? Regular crashes - couldn't find the source of the problem. Had multiple lag issues and found performance to be sluggish. Fourth, were you running 64bit or 32bit logic? 64bit. Hope that helps.

I upgraded those, changed to 64bit, but still, same issues, so, think i'm going back to SL. Link to comment Share on other sites More sharing options...
1j1 Posted February 5, 2013 Author Share Posted February 5, 2013 Peachboy (i'm being extra careful, so, I hope you don't mind extra questions). you say Yes they worked okay. I copied over individual folders like the Channel Strip settings, plugin settings etc, rather than the entire Library folder. Haven't experienced any problems since. Had you started any/many new projects on ML that you transferred to SL? If so I'm guessing these were fine as you've reported no issues. Same for sampler instruments, channel strip settings, etc. Did you create any in ML that you transferred to SL? If so, again, I'm guessing these were fine as you've reported no issues. Thank you for you input. Link to comment Share on other sites More sharing options...
Simon Morrison Posted February 6, 2013 Share Posted February 6, 2013 Ok, so, the problems are with NI plugs for sure. OK - midi-triggered VIs. Some suggestions: 1. Install the latest driver software for your audio and midi interfaces (even if they are not connected) 2. Install the latest iLok software (not used by NI, but needed for Mountain Lion) 3. Set Logic's Process Buffer Range to Large I suspect that there may be some older/incompatible 3rd party software installed. E-mail me a copy of your System Information report and I will troubleshoot: 1. Select "About This Mac" from the Apple menu 2. Click "More Info…" 3. Click "System Report…" 4. Select "Save…" from the File menu 5. Save the report on your Desktop Link to comment Share on other sites More sharing options...

1j1 Posted February 7, 2013 Author Share Posted February 7, 2013 Thank you Peachboy and Simon. Simon, re: Some suggestions:1. Install the latest driver software for your audio and midi interfaces (even if they are not connected) Lags/problems happen without even using audio interface. 2. Install the latest iLok software (not used by NI, but needed for Mountain Lion) Why do I need iLok? Some of my plugins are old and I can't find the boxes and subsequently codes for them, so am dubious to use this. 3. Set Logic's Process Buffer Range to Large I have tried this, to no avail. Still, I didn't need to do these things before, which suggests to me incongruities between Logic and ML and my computer in general. I suspect that there may be some older/incompatible 3rd party software installed. There is older software, but, I don't want to get rid of anything as it might affect old projects that I may go back to work on. E-mail me a copy of your System Information report and I will troubleshoot:1. Select "About This Mac" from the Apple menu 2. Click "More Info…" 3. Click "System Report…" 4. Select "Save…" from the File menu 5. Save the report on your Desktop What specifically do you need to know? No offence, I'm sure you understand, but, I am a little dubious about sending my entire system information, including serial number + other info etc to someone who A: I don't know and B: is not with apple.

1j1 Posted February 7, 2013 Author Share Posted February 7, 2013 Also, Peachboy, what version of Logic are you on now? Link to comment Share on other sites More sharing options...
Simon Morrison Posted February 7, 2013 Share Posted February 7, 2013 Install the latest iLok software (not used by NI, but needed for Mountain Lion) Why do I need iLok? Some of my plugins are old and I can't find the boxes and subsequently codes for them, so am dubious to use this. Older versions of iLok (PACE) software are incompatible with Mountain Lion and Logic Pro - you may experience system slowness and freezes/crashes in Logic. To find out if iLok software has been installed on your system, look for a file beginning with "PACE…" in the following folder: Macintosh HD > System > Library > Extensions I suspect that there may be some older/incompatible 3rd party software installed. There is older software, but, I don't want to get rid of anything as it might affect old projects that I may go back to work on. I am referring to system level software, such as iLok (above). What specifically do you need to know? I would like to see what System Extensions are installed (Macintosh HD > System > Library > Extensions) - older 3rd party extensions can cause system problems including slowness, freezing and crashing. I'm an ex-Apple engineer. Link to comment Share on other sites More sharing options...
1j1 Posted February 7, 2013 Author Share Posted February 7, 2013 Hi Simon, Thank you again for your input.

To find out if iLok software has been installed on your system, look for a file beginning with "PACE…" in the following folder: Macintosh HD > System > Library > Extensions No PACE file on here, so I guess no iLok? Does this mean that not installing it is not a problem? I would like to see what System Extensions are installed (Macintosh HD > System > Library > Extensions) - older 3rd party extensions can cause system problems including slowness, freezing and crashing. I'm an ex-Apple engineer. Ok, if it helps, attached are screen shots of the entire extension folder/section. Any suggestions to help get me running lag/bug free would be much appreciated.

Simon Morrison Posted February 8, 2013 Share Posted February 8, 2013 No PACE file on here, so I guess no iLok? Does this mean that not installing it is not a problem? No iLok + no iLok software = OK Ok, if it helps, attached are screen shots of the entire extension folder/section. Any suggestions to help get me running lag/bug free would be much appreciated. Several Apple system extensions appear to be pre-Mac OS X 10.8.2. 1. I recommend that you download and re-install Mac OS X 10.8.2 using the "combo" installer: http://support.apple.com/kb/DL1581 2. Update Soundflower to version 1.6.6b: http://code.google.com/p/soundflower/downloads/list 3. Remove the "InstantOn" and "InstantOnCore" extensions by dragging to the Trash - you will need to authenticate to complete this. Restart after removing these. 4. Delete the Logic Pro cache folder: a. In the Finder, press and hold the "option" key, then select "Library" from the "Go" menu b. Open the "Caches" folder c. Drag the folder "com.apple.logic.pro" to the Trash Let me know if you see an improvement after completing this. Link to comment Share on other sites More sharing options...
1j1 Posted February 11, 2013 Author Share Posted February 11, 2013 I'm going to attempt your suggestions tomorrow. Fingers crossed it works Link to comment Share on other sites More sharing options...
1j1 Posted February 15, 2013 Author Share Posted February 15, 2013 Right. I was having other issues with my system so I decided to do a clean install of ML. Also, someone at apple suggested that doing clean installs of both ML and Logic might help. So, after a clean install of Logic AND, all of my third party plugins, in 32bit mode still serious lagging. I've installed the latest NI updates, still getting lag/freezing. I have tried it in 64 bit mode, not AS much lag, but still freeze/lag issues. Also cracks and pops in both 32 and 64 bit mode. Any more suggestions? If you could get back to me as soon as possible that would be very much appreciated. I've only got a few more weeks left on my general applecare (i don't have logic applecare) so I need to get this sorted before it runs out (incase through the re-install/moving files about process something goes wrong and I need their help). I think going back to SL is all I have left to do now. I'm just worried that the 9.1.8 update in SL will result in issues in SL too. :/ Link to comment Share on other sites More sharing options...

I should have probably said, I did all written above AND, of course, followed the steps you suggested, though, after the clean install the 2 instanton extension files weren't there anymore, so I didn't have to remove them. I made a copy of the logic cache in a separate folder on my desktop and then deleted + emptied the trash and I installed the combo update (in the order you specified).

redlogic Posted February 16, 2013 Share Posted February 16, 2013 Thanks redlogic. Did you try ML have problems and go back to SL? Nope. I'm on a 2007 Mac Pro 1.1 that won't boot into the 64 bit kernel, so no Mountain Kitty for me. I'm stuck on Snow Kitty until I get a newer Mac.
