Moving to a Mac? That's even worse. There are quite a few VSts that stop working when a new OS comes out. At least you have a work around instead of 1) upgrading and waiting until the manufacturers update or 2) don't upgrade yet. Then again, at least you have the choice to not upgrade.
Not my experience. Put Sierra on my DAW Macbook yesterday, the last of three different spec Macs I've upgraded. There are problems with plugins from certain developers, including some very big ones that seem to have not being paying attention, but none that affect me.
A bit to my surprise, everything works. Needed to disable the pestilential Siri and switch unwanted "store loads of stuff in the cloud" settings off and that was pretty much it. At least unlike Win10 it didn't let me disable functions, including privacy-related one, during the install process only to quietly switch them on again at first boot and again after updates, Aqua looks and works like it did before and everything's where I expect it to be.
I've used MS operating systems from MSDOS6 onwards, but Win10 as it currently operates is the step too far for me. The last time I recall Windows updates causing as many problems as Win10 updates seem to is XP service pack 2 when MS finally bit the bullet and clamped down on the security and user account permissions stuff, which broke quite a lot of software that had been developed outside MS's recommended guidelines.
Apple have it relatively easy of course, because they only have to code for their own limited range of (expensive) hardware, not for a myriad of combinations of third-party components. And they still have security issues at times and bugs and compatibility problems, but the law of large numbers means that once any software is rolled out over tens of thousands or millions of computers stuff the developers and testers missed is 99.9% likely to turn up. In the end, just as with cars, instruments and washing machines it comes down to what you prefer, what you need a computer to do and the available budget.
