Hi, I have just had a new SolidState Drive put into my iMac (24' early2008).
It has Processor 3.06 GHz intel core 2 duo.
Memory : 4GB 800 MHz DDR2 SDRAM
Graphics : NVIDIA GeForce 8800 GS 512 MB
Running El Capitan 10.11.6
Logic Pro 9.1.8 (1700.67) 32-bit
What I'd like to know is after logic crashed today after using it are they compatible
Any help would be great! thanks.
iMac, Mac OS X (10.6.8), LaCie drive
You can boot Logic 9.1.8 in both 32 and 64bit. Just 'Get Info' on the Logic app icon and untick the 'Open in 32bit' tick box.
I have gotten 9.1.8 working under 10.10.x quite successfully but stopped in my experiments there. But Logic 9.1.8 can be booted in 64 bit mode.
El Capitan is a 64-bit only OS. The version of Logic Pro you have is 32-bit. I doubt it will run reliably. However, you will need to find out what the system requirements are for that version (I don't know.) The current version is 10.3. I suggest you upgrade your version. Also, see App Compatibility Table - RoaringApps.
Hi CCTM, I wonder, I am thinking of switching to 64 bit from the 32 bit my logic is currently set to (it has always run on 32 bit) Do you know, if I switch will it muck up my work I have already completed or work in progress in my logic? thanks for your help!
You can switch at will. If you have any 3rd party 32-bit only plugs Logic will attempt to load them in bridged mode. Other than that, if you have an issue with a project you can just switch it back to 32 bit mode with no harm done.
The bridge mode is a helper app (located in /Applications/Logic Pro.app/Contents/Frameworks/MAAudioUnitSupport.framework/Versions/A/32-Bit Audio Unit Bridge.app) that will automatically launch if you activate a 32-bit AU plugin when Logic 9 runs in the 64-bit mode.
I'm seeing it often while mastering, because the old TT Dynamic Range Meter is 32-bit only.
Occasionally the 32-Bit Audio Unit Bridge.app may crash (and relaunch) but the rest of Logic usually remains unaffected. At least I haven't noticed any serious issues whatsover, but TT DRM is also the only 32-bit plugin I'm using regularly. Nonetheless it is always a Good Idea™ to relaunch Logic too, if the helper app crashes.
Thanks for your help Kappy. I will check the system requirements as you suggest. Thanks for the useful link also!
Hi
Whilst I generally use LPX, LP9.1.8 64bit runs fine on OS X 10.11.6 here ( as does LP9.1.8 32 bit).
Make sure to turn off iCloud Drive

Thanks Octopi, I'll look into that!
Thanks CCTM, that's very encouraging!
Sorry, I couldn't mark your comment as helpful because the link doesn't work for me.
Ok thanks Octopi. What is bridge mode? How does that work?
Hi Lucas,
Thanks for taking the trouble to reply in such detail, that is very helpful!
El Capitan 10.11.6 and Logic pro 9.1.8 are they compatable?
