Latest OS X & Logic Pro Compatibility Information
Note: What follows is a series of personal opinions and advice based on my own experiences and those I have gleaned from other, long time, users of Logic Pro... and should be regarded as such. 🙂
Update: July 26th 2015: Reference El Capitan / OS X 10.11. I (and hopefully others...) will be testing and publishing results and further information on compatibility here, after 10.11 is out of Beta..... Bear in mind most issues relating to Logic after major OS X Upgrades are usually caused by incompatible drivers for external devices or 'broken' 3rd party plugins... Do not upgrade unless you have made full 'clone' backups using something like SuperDuper! or Carbon Copy Cloner beforehand, of your current system disk so you can easily roll back if things no longer function correctly after upgrading OS X.
Update: 20th May 2015: Logic Pro 9 working okay for some users under Yosemite 10.10.3.. though not optimally.... but that's because Yosemite adds/makes a much high demand on system resources For others however, the combo of Yosemite and LP9 is still proving to be unstable so bear this in mind. Ensure any hardware drivers used are fully compatible with 10.10.3 before upgrading to Yosemite.
Previous recommendations for Logic Pro 9 users to stay with earlier OS X versions (Preferably 10.6.8 for best performance) still apply for more optimal performance.
Logic Pro X 10.1.1 and Yosemite 10.10.3 seems to be relatively stable.... so long as any external hardware drivers are compatible with 10.10.3 However, as Yosemite seems to make more demands on hardware, there is likely to be quite a noticeable performance hit using LPX and Mavericks/Yosemite compared to the LP9 and Snow Leopard combination
Update: Currently, as of April 4th 2015, the combination of Logic Pro 9 and Yosemite (10.10.x) is NOT recommended as many people are reporting performance/stability related issues. If you have already upgraded to Yosemite, use your backups and 'roll back' to an earlier OS X such as Mavericks though some users still report issues with LP9 under any later OS X version than Mountain Lion.
Further information on how to roll back to an earlier OS X version, if you have been using Time Machine for your backups, can be found here...

For other backup applications such as Carbon Copy Cloner or SuperDuper! refer to the Users Guides for those applications.
Additional : Logic Pro 8 or earlier, will not run correctly with Mavericks nor Yosemite.
================
Update March 20th 2015 - After preliminary testing of LPX 10.1.1 and the final version of OS X 10.10.2.. Most of the performance related issues appear to have been resolved. So long as you have made good backups of your current system drive, your external hardware is compatible with Yosemite.. and you are not in the middle of some critical project.. then give the update to OS X 10.10.2 a shot... and see how your system gets on with the combination.
I do not recommend using the public beta of 10.10.3 at this time.... with Logic Pro
Recommended OS X and Logic Pro Combinations: Mar 2015
Logic Pro 8 - Snow Leopard 10.6.8 & LP 8.0.2 (Under Mavericks and Yosemite, LP8 has major issues)
Logic Pro 9 - Snow Leopard 10.6.8 & LP 9.1.5 (Note: LP9.1.8 is also stable and almost as good as 9.1.5 but not quite, performance wise)
Logic Pro X - Yosemite 10.10.2 & LPX 10.1.1

Update: Dec 30th 2014 - Sweetwater have updated their Yosemite Compatibility resource that can be found here....

For anyone, for whom working with Logic is important... and who is thinking about updating their current version of OS X....
Don't!!!!
At least not until it has been fully tested with different hardware/software/drivers etc.... and after ensuring that your current hardware is compatible with the version of OS X that you wish to upgrade to.. and has the appropriate drivers, where applicable.. that work and have been fully tested with that new version of OS X
If you really want to try out a new version of OS X then install that OS X version on to an external Hard Drive, install Logic Pro on that drive along with any drivers/plugins etc... and then boot to that. and test thoroughly.... leaving your current configuration alone and working...
or...
Make a full clone backup of your current system drive using something like Carbon Copy Cloner or SuperDuper! (My personal choice) to an external drive before you update to Yosemite and then if things don't work out you can quickly and easily revert back to your current config with ease..
Note: The sole use of Time Machine as a clone backup is not recommended as not all files will be restored correctly and you may find you have to do a great deal of manual tweaking/fixing/re-registering to get everything back to normal. TM is great for individual file restoration but for full cloned restores, not so good!
Based on past experiences.. as seen by the many 100s of posts made in the Logic Pro forum after the release of Lion, Mountain Lion, Mavericks and Yosemite...there could well be incompatibility issues that will rear their ugly heads upon the launch of the next new OS X version... so be warned!
So again... as always when OS X or Logic Pro is updated... Take your time and let others find the bugs/issues etc before you install it yourself.. or if you insist on doing so.. make proper clone backups first... to save a lot of wasted time and effort later.
