I have noticed that a few people are re-installing the OS when they get their new iMac. Is this only to get rid of unwanted bloated files i.e language, or is their any other reason. I didn't go down that route, I just removed some language files using a third party software. (Clean my Mac) Plus I do not want windows on a separate boot partition, I prefer the VM solution, this suits my needs perfectly, so adjusting drives for partitioning was not an issue. Thanks. By the way, this forum is fantastic, and I like to thank everyone who has taken the trouble in answering my questions. Sometimes google is not always the answer, and having the ability to ask fellow iMac users, some with a fast amount of experience a simple and sometimes trivial question to some, and get answered quickly is great.
