This could be the most straight forward MacOS update I have ever performed (I have been doing them since System 7.5 ).
This time all three machines (iMac, MBP and MBA) worked first time with no dramas. As always the first thing I did was a full TimeMachine back-up (I have been burnt before) and then downloaded a copy of the Yosemite install from the AppStore. Rather than do an in-place upgrade I always do a clean installation, for the last three releases I have used the excellent DiskMaker X (or Lion Disk Maker as it used to be known) . Once I have a USB installer I rebooted into the USB disk and then erased my primary hard drive using the disk utility, which is always a fun moment.
Once the new system had installed and I have logged in the first thing I do is install the Command Line Tools , once they are installed Brew can be installed and then Cask …….
Now its time for the none AppStore software ….
Finally open the AppStore & install the rest ….
…. other than putting the Apps in thedockand actually adding licenses etc that was it.
The only real issue I had was that the machine needed a reboot to kickiCloud Driveinto life. The only thing I don’t like so far about the visual update to goto in the the Mini player iniTunes 12you have to hover over the artwork in the player, which is ok. However, to return to the main window you have to click the window close icon which just feels wrong.
I suppose one little annoyance out of such a major update isn’t bad going, but grrrrrrr.
