Improvements?
I don't know what kinds of improvements Apple is making with each beta. Those of you who are testing these betas, can you share your general opinion about the stability, graphics performance without violating your NDAs? 10.8.3 brought lots of improvements for me, but I still believe a bug related to mdworker or Spotlight indexing is still present in 10.8.3. It caused system lockups on my rMBP before, however booting it once in the Safe mode lockups disappeared. Though, Spotlight indexing related bugs has appeared now, e.g. when I download a PDF file using Safari's Download to Stack option, Spotlight refused to assign any date and size information to the PDF downloaded. After I restarted the rMBP, it went away. Apparently, there are changes to Unix in 10.8.3 as well. Some of the unix commands that worked well in 10.8.2, do not work anymore or have to modified slightly in 10.8.3, including the mdfind command for searching the files on my rMBP and defaults command for changing the certain system behaviour. Can anyone share thoughts on these...
