Yosemite Upgrade


Well, Apple released Yosemite just recently. I have been using the beta for a few months and it seems that it is pretty ready for prime time. So, I decided to download and upgrade both my 2012 iMac and 2011 MacBook Air. This is a major upgrade so here is what I did.

First, I went through and updated as many programs as possible. I have tons of software, but of paramount importance were my “mission critical” apps like banking, web design, etc. Once those were updated as far as I could go (some updates will not install until Yosemite is installed) I then did the usual upgrade procedures. This was all on my Late 2012 iMac.

I ran permissions on my Mavericks install. Then I cloned my system to an external hard drive and booted from that drive in case Yosemite was a total mess and I
 needed to clone Mavericks back over. I also ensured that I had a Time Machine backup. Here is a shot of SuperDuper! cloning my machine:

Then, I downloaded the Yosemite installer. Let me tell you it is huge!! The Yosemite installer is a little over 5GB in size and it takes a while to download. Once I had the installer downloaded it tried to install Yosemite on my iMac, but I QUIT the install. I then moved the installer from my Applications folder. The reason for this is if you let Yosemite just go through a normal install it will delete the installer when it is done. But, I wanted to make a standalone USB installer with it (article to follow on this procedure) to use on all my machines and friends machines as well, so I did not complete the installation in the normal manner.

Once I had the installer created on an 8GB USB Thumb Drive, I used it to install Yosemite on my iMac. Installing Yosemite “over the top” of Mavericks OS (or another version of OS X) is quite a process. Here is how it went on my Late 2012 iMac, YMMV. If you have not installed already I urge you to read this article first  There are long pauses at places during the install, you just have to wait them out.

  1. The first screen said “Preparing to Install”. This screen stayed at “1 second remaining” for about 10 minutes. This whole process was about 20 minutes.
  2. The machine Restarted, there was a progress bar for about 5 minutes, then finished quickly.
  3. Then it went into the actual install. It said 18 minutes and took about 20 minutes.
  4. Next was a restart with a progress bar and SBBOD (Spinning Beach Ball of Death) which lasted about 8 minutes and ended at login screen for iCloud. This is a two-step authentication if you have that setup.

After this rather convoluted process my machine finally booted in OS X 10.10 Yosemite. After this startup I automatically did a normal restart. Then I proceeded to install a ton of application updates through the App Store. Then I ran Permissions using the Disk Utility app.

At this point in time, all seems to be working well. A couple of minor Mail Application extensions that I use will not work, but I am sure the developers will fix that post haste.

All in all everything is working fine. I really like Yosemite. I have not tried many of the new features yet, but will in time.
