Skipping the upgrade for the first time in 18 years.
Losing 32 bit apps like indesign CS6 is just too much.
Unless someone can suggest a parallels VM solution?
Stay away from Parallels. Super expensive, horrible support.
I had it for 1 year and I stopped subscription.
I moved to VMWare, not the best but works fine. I am also thinking on holding back however this is not Apple's fault.
Lazy developers don't update their SW for 64 bits since many many years. I agree with Apple that 64 bit should have been a standard long ago and they have sent many warnings to users and devs as well that their apps will no longer be supported.
In the same time, it does impact me quite a bit but I have 2 machines so one will be around until I find SW companies that make 64 bit code and do what I need.
To be honest, I cannot blame developers either. The world of consumers goes mobile fully (phones and tablets) and the laptop market is not the biggest cash cow, so no wonder their efforts go that direction.
So I suppose businesses are more inclined to invest in places where they can make more profits.
Maybe it's just me, but I start to see a clearer delimitation between uses of OS-es like it was in the past:
Linux - SW Development for VMs, Real-Time embedded systems, servers and security appliances
Windows - Gaming and some level of content creation
Mac OS X - Content Creation only (music, videos and photography)
iOS, iPad OS, Android - consumer social media, gaming, consumer content creation
This is maybe why Mac OS X is now lagging behind in release dates and does not care anymore for legacy 32 bit SW, it's simply not worth the effort.
