Yosemite has just been released. Like any new OSX, it has various problems with the first release, so unless you really need it, I’d wait for the first minor update to come out to fix some of the buys.

If you decide to install Yosemite, here are a few things to be aware of before you upgrade.

• By default Yosemite will default to encrypt your entire Hard Drive. This potentially means if you forget your password ALL YOUR FILES WILL BE UNAVAILABLE.  Make sure to turn this off unless you understand the consequences. I think this should have been opt in rather than opt out.
• Dragon Naturally Speaking There were some issues but this has been resolved.
• Fuji Xerox printers don’t work.   Here is a workaround.
• non Apple SSD as startup disk with TRIM enabled – there could be issues. See here for a more detailed explanation and here for a discussion.
• Problems with Gmail and Apple mail where you cannot log in to check your mail – password error. Tis can be solved by deleting your gmail account from Apple mail then putting the Gmail settings in again.
