Common problem is when people turn on Time Machine, then for whatever reason don’t connect the external drive to the system for a lounge time. OS X will create a whole bunch of offline backups waiting for the next time the time machine volume is available. Here’s a good starting point: https://support.apple.com/en-au/HT204015 > What's a minimum hard disk free space one should maintain on a Mac? I generally use a 10% rule-of-thumb regardless of the OS. Maybe a little more if you have logs and temporary data on the same volume as your startup drive. In Linux, I usually keep “/“ and “/boot” away from “/var” for instance, in which case I can comfortably maintain 10% or even less free as the data is mostly static. > This runs OSX 10 7 5, to upgrade to Yosemite, is it just 'click and watch'? > How much free space should I make before attempting upgrade? Not sure about inline upgrades from 10.7 straight to 10.10. You can always go to the app store, download 10.10 the run the bootable media creation utility: sudo "/Applications/Install OS X Yosemite.app/Contents/Resources/createinstallmedia” sage: createinstallmedia --volume <path to volume to convert> --applicationpath <path to Install OS X Yosemite.app> [--force] Arguments--volume, A path to a volume that can be unmounted and erased to create the install media. --applicationpath, A path to copy of the OS installer application to create the bootable media from. --nointeraction, Erase the disk pointed to by volume without prompting for confirmation. Example: createinstallmedia --volume /Volumes/Untitled --applicationpath "/Applications/Install OS X Yosemite.app" > Are there any good housekeeping utilities to use, going through some apps, > I've found a photo app with over 1 g of deleted photos. > (something like ccleaner ?) Any hard disk area to check for junk, like temp > in windoze? There’s a few around, but I found, generally speaking, OS X does a pretty good job of looking after itself. Certain applications can be big disk hogs though - iPhoto, iMovie and iTunes spring to mind. They generally have their own “deleted stuff” which if you don’t clear out in the application itself won’t be released when you empty the normal “Trash” on OS X. Having said all that, “Disk Inventory X” is a GPL tool that will show you where all the space has gone: http://www.derlien.com - check it out, it works well. As for getting rid of stuff remember OS X is a fully-fledged Unix so most of the familiar command line tools are available in a terminal :) > Thanks for any pointers No worries - hope it helps :) Cheers, James
