Questions about Sierra install

[AllGold]

I have two machines running 10.9.5, a 2012 15" MBP and a 2012 Mac Pro. I upgraded both to 10.12.6.

The MBP was a piece of cake. It is more of a work machine; I don't have anything on it other than photography tools. I don't even use it for email.

The Mac Pro is stuffed with drives and has all my non-work things (as well as the same photography tools). I had all sorts of trouble with Update in the App Store. It didn't want to download updates and kept giving me an error to the effect of "Network lost connection. (-1005)" I had to try literally about 100 times over two days before the security update would download.

Both machines used the exact same internet connection, although obviously at different times.

I'm a little suspect about the Mac Pro installation and am trying to decide whether to roll back to the pre-upgrade Time Machine backup and do the Sierra install over again. What do you think?

You might try an over the top re-install of Sierra?
Otherwise-do a Fresh install of Sierra on a blank internal drive-then migrate in your info. Many times this is better than upgrading in place.

Thanks.

I already did the first and it didn't help. I thought of the second as well, but really hating the idea. :wink:

The Mac Pro is stuffed with drives...

If you have a mix of SATA-II internal bus mixed with a PCI-e device it may cause
issues, especially if there's a firmware update involved. Also, some PCI-e cards like
USB 3.x controllers can cause conflicts.

Doesn't happen all the time but it can drive you friggin crazy!

When you installed Sierra, did the installer also do a firmware update? If not, no matter how much you hate the idea, you’re going to have to install it on a drive connected to one of the internal SATA connections.

Yeah, my boot drive is an SSD in a PCIe card.

I do have something I can install on the SATA bus rather than the PCIe card.

But I thought Sierra didn't need new firmware--only High Sierra and beyond.
