You need to address this complaint to Apple. This forum is for help with application issues, functionality and bugs.
I am interested in your comment, 'For those who don't understand'. Understand what?
There have been plenty of warnings about updating OS's and the implications of using older applications. There is no conclusive evidence that updating OS makes an application work better, in fact on the contrary.
I get so sick of people complaining about issues after updating their OS. Do your homework and check if a particular app, will work with a certain OS. You don't say how long ago you purchased Logic Pro at $200. Man that is cheap and the cost could be recovered in the charge for one small Logic Project, assuming that you make a living out of Recording like I do.
I run Logic 7 & 9 with OS 10.8.5, can't update because of interface driver issues. Anyway, LP 9 will let me do all I need without upgrading to LP X and still make a living out of it.
I have the ability to run apps, twenty or so years old, up to current versions. Some older versions of apps, work better than updates. Apple seems to dumb down updated apps, like iMovie, Final Cut Pro and Logic, my bread and butter.
Hard Drive storage is dirt cheap. Get yourself a large HD or maybe two or three and partition them with OS 7 to 12 and be able to select the OS to suit the application required, old or new.
If you are a serious Mac user and progressed through the OS upgrades, then you will have the original discs, right?
No! Then buy them and stop complaining about the cost of Apple software and Hardware.
