Mac OS X 10.9.3 upgrade to 10.10.4 record

Last night, I couldn't help it. Upgrade Mac Pro OS from OS X 10.9.3 to 10.10.4, because the network does not give force, 500K/S, light System package to 5.6G, so a whole down to work during the day, and so on after work to start the installation, but the installation process is not too smooth,

Installed to show only 2 minutes left, waiting for 2 hours, I do not give up the idea of upgrading, and then restart, no, or to the installation page, this is the first time I installed OS X; I don't know how to toss it, I can only follow Apple's default arrangement. This doesn't matter, wait until the Mac has no power position, or not,

Then the next day will not forget, continue .... Or 2 minutes left, Tick tock .... From 8 o'clock until 10:30 only reaction, hehe, finally can see the progress, and then restarted the 4-5 times it, only the Settings page.

After setting up to continue, enter the password, finally upgraded successfully, the data are still in, just the system updated. Apple's system upgrade is good. Is the hint seriously inaccurate, Baidu also does not have the corresponding description, or share.

So write it down and give us a wake up call!

Finally, a post-upgrade diagram.
