Wow – Yosemite (Mac OS X 10.10.1) still sucks, completely.
I can install Yosemite to an empty drive fine and start from scratch. That mostly works, though it makes my mid-2007 iMac (2GHz, ATI Radeon 2400, 4GB, 250GB SATA) run very slow and I hate the way it looks.
I cannot successfully run Migration Assistant to pull from a good backup of my working Mavericks system backups; Migration Assistant never completes, saying it has about 2 minutes remaining after 8 hours, and then staying at 2 minutes remaining for days (tested to 3 days). Quitting Migration Assistant and trying to use the system it is broken… Finder cannot see Applications, the Dock is frozen and unresponsive, Spotlight can find nothing.
I cannot upgrade Yosemite on top of the existing Mavericks system without loosing ALL Applications (including the ones from Apple). Same details as scratch install and migrate data; Terminal can list the files in /Applications; but Finder cannot see them.
I have to say I hate the appearance of Yosemite even on the working blank system.
Thank goodness for backups.
Thank goodness for Mavericks.
To be fair this is on some pretty old hardware, a Mid 2007 iMac 20″ (iMac7,1) with 2GHz Core2 Duo, ATI Radeon HD2400, 4GB memory, 250GB SATA spinning drive that is 87% full). Officially the oldest iMac that can be supported for Yosemite, barely. Chief complaint, on upgraded system is that Applications folder appears empty in Finder, though terminal can see the files listed. Dock is unresponsive, clicks never get acknowledged at all. Spotlight search is very slow (2 minutes to find and launch Terminal). Stock hardware, no changes; but I do have seven years of software cruft and all applications since initially running Leopard (10.5) back in 2007; though I purged a lot to upgrade to Lion as the PowerPC emulator vanished then.
