So, other than the color of the dock looking comical, Mavericks works great for me EXCEPT I use my MBPr at home and work and access a file server via SMB to hold all my work, movies, music, etc. I can connect, via the old CMD+K method, and via clicking the server in the Finder sidebar, and no matter the method I use to access the servers, when I double click to open a file (excel, word, pdf, etc) it says "The application 'Excel, Word, Acrobat' can't be opened. -36". If I copy and paste the file to my local SSD then it opens fine. This is a massive issue for being able to quickly work. Even worse is that hitting the space bar to get a quick preview works perfectly. Any ideas on a fix/workaround? I hope to god Apple fixes this immediately. This is massively bad.
