Running Yosemite on a 2011 rMBPro w 16 GB RAM. The problem is with RAM mgmt. When using MS Office & Acrobat Pro on documents around 1-10 MB (writing a book in separate chapter documents), the available system RAM would reduce to a mere MB level. Re-install of OS did not fix the issue as it is persistent and resident within the latest Yosemite release as of this post. Just using Safari would take the available RAM down considerably as well.
Read forum posts that Yosemite RAM mgmt uses free RAM to speed processes (vice older OS that did not use free RAM unless requested by programs), as long as the "Memory Pressure" was green in the activity monitor. What good is free RAM if it is not being used to speed up programs right? Well the system pressure would be green, but the avaliable system RAM would be xxx MB and my documents refused to save because there was not enough system memory. Therefore, the "Memory Pressure" color of the activity monitor in Yosemite is just as reliable as the "System Idle" in windows task manager that would show +90% whenever Windows would crawl and freeze due to obvious CPU overusage not reflected by the software.
Due to many lost hours of work (combined from multiple work sessions) and using Memory Clean every 5 minutes just to have enough RAM to save my documents if I was lucky to get enough back, I decided to go back to Mavericks which does not have any of these problems. Constantly using Memory Clean, Control-Command-Power, and restarting to get my free RAM back gets old after a while. Other than the RAM issue, everything else worked great! Not a fan of the flat icon look (somebody make a retro OS X theme to bring em back on Yosemite) but the rest of the OS was impressive in functionality. Don't think I will upgrade again until I confirm that this problem is fixed without doing a myriad of Terminal commands (trusting someone else's code solutions) that does God knows what to my computer.
